Resumen

Rota Island, the southernmost island in the Commonwealth of the Northern Mariana Islands in the western Pacific, has the types of caves previously documented on the other limestone mantled islands in the Mariana Arc that have been investigated for caves: Aguijan, Guam, Tinian and Saipan. Caves developed at the edge of the fresh-water lens by zones of enhanced carbonate dissolution produced by fresh-water/salt-water mixing are most common. Among these mixing zone caves, flank margin caves dominate. Flank margin caves were found singly and in extensive horizons representing significant sea-level still stands. However, another type of mixing zone cave was found on Rota in numbers not documented on neighboring islands. Mixing zone fracture caves, apparently formed as zones of enhanced dissolution, produced fresh-water discharging from the lens along fractures, migrated vertically as sea-level changed. Some mixing zone fracture caves on Rota are developed in clusters from two to four caves. The mixing zone caves of Rota reflect the interaction of eogenetic limestone, glacioeustasy, local tectonics and enhanced carbonate dissolution via mixing of disparate waters. The development of mixing zone caves on Rota is in agreement with the Carbonate Island Karst Model (CIKM). Rota has a few caves developed along the contact between limestone and the insoluble volcanic rock that makes up the core of the island. The most important of these is Water Cave, a large spring that is the source for most of the municipal water on Rota. Rota also two extensive zones of vertical fissures developed along bedrock fractures; Fissure City and As Mundo Fissure Zone. In addition, Rota has one cave apparently developed along a fault; Gagani Cave. Some of the caves documented on Rota are difficult to classify and warrant further investigation.

Resumen

The problem studied was the poor academic achievement of middle school students in the Commonwealth of the Northern Mariana Islands (CNMI). Research indicates that a growth mindset positively affects a student's academic achievement and motivation to learn. However, despite the importance of mindset in fostering student success and enhancing learning, mindset remains underexplored in the CNMI. The purpose of this generic qualitative study was to fill this gap in knowledge by investigating teachers' knowledge, perceptions, and practices concerning mindset in the CNMI. Three research questions examined teachers' knowledge and perceptions of mindset in the CNMI and how teachers described and demonstrated the use of mindset in their practices. Dweck's seminal work on mindset served as the conceptual framework. Social constructivism guided the study process. Qualitative data were collected from 15 purposively sampled teachers at a local CNMI middle school. Data were analyzed through categorization and codification, from which emerging themes were used to answer research questions. Results indicated that teachers in the local middle school have limited knowledge and inaccurate perceptions regarding the mindset concept. Accordingly, the analysis recommended the need for and served as the basis for the design of a professional development workshop about mindset for teachers throughout the CNMI to enhance teacher instruction and improve student learning, thus promoting positive social change.

Resumen

Master of Science<br>Department of Apparel, Textiles, and Interior Design<br>Joy Kozar<br>This study examines colonization, development, and globalization in the Commonwealth of the Northern Mariana Islands (CNMI) with respect to the garment industry, the main industry of the islands. A broad-reaching analysis examined population, gender, economic factors, and import/export data in order to explore the repercussions of garment industry development and subsequent decline on the CNMI. A quantitative analysis was conducted utilizing data from the United States Census Bureau, the CNMI's Department of Commerce, and the U.S. Department of Commerce Office of Textiles and Apparel. This research illustrates how the effects of the garment industry in small developing nations are dramatically impacted by a trade arrangement, the Multi-Fiber Arrangement (MFA), which was a protectionist measure used to restrict manufacturing of certain product through a quota system. In addition, this study reveals the economic implications and societal outcomes for the CNMI after the collapse of the garment industry as a result of the 2005 MFA phase-out. Garment production orders shifted to large producer nations once quota restrictions were no longer in place. Factory closures, lost business revenue, and a loss of manufacturing positions affecting predominantly women plagued the CNMI as well as cost-of-living increases. Federalization of the CNMI took place in 2009 which further complicated the islands’ politics and guest worker population status. Tourism is now the CNMI's chief industry although its growth is dismal and heavily reliant upon world economies. A comparison between Mauritius, another small island nation, concludes the discussion with insight on women's development and future considerations for economic growth as a means of development and dependency in the CNMI.

Resumen

Background: At the end of 2009, there were 33.3 million people living globally with the Human Immunodeficiency Virus (HIV) with 2.6 million new infections occurring annually (UNAIDS, 2010). In the Commonwealth of the Northern Mariana Islands (CNMI) in the Western Pacific Ocean, annual STI and HIV statistics as of 2009, indicate that syphilis, hepatitis B and herpes simplex virus are at their highest rates since 2002. This study documented the understanding of the social, risk and sexual behavior among a cross-section of the population in the CNMI. The primary objective of the study was to establish baseline behavioral data on STIs and HIV/AIDS in the CNMI.Methods: Behavioral information was obtained using a modified version of a survey based on the Family Health International STI/HIV/AIDS Behavioral Survey for adults adapted specifically for use in the CNMI. The questionnaire was administered to three population groups in the CNMI: The first consisted of pregnant women (n=228) who were attending their first prenatal visit and who had not been previously tested for STIs. The second consisted of men (n= 132) over 18 years of age who had engaged in sex with another man during the last five years. The third group consisted of male and female youth (n=433), aged between 18-24 years, were unmarried or had been living with a partner for less than 12 months prior to the survey date. The survey comprised of a variety of questions including personal background history, marital history, sexual partner history, sexually transmitted infection history, condom usage, alcohol and drug use. Additional information was obtained on the participant’s level of HIV/AIDS knowledge and access to HIV testing.Analysis: The data was analyzed using SPSS Statistics Version 17. Frequencies of all the variables were undertaken and bivariate analysis was conducted to determine statistical association between continuous and categorical data. Chi-Square analysis was used to determine if differences existed between prevalence figures and categorical variables and analysis of variance (ANOVA), was used to determine if differences existed between continuous variables.Key Findings: Results from the prenatal survey group indicated that the majority of the respondents (66%) were unmarried, unemployed Micronesians (54%) who had never used a condom and who were not using any form of birth control. Most were living with a partner (70%), and none had ever injected drugs. Information about STIs and HIV was obtained through the television, newspaper, the internet, radio and friends. The majority of pregnant women (94%) were aware that they could pass HIV on to their unborn child, however a quarter of the women were not aware that they could pass HIV through breastfeeding. During the last twelve months, the majority of women (99%) had only one sex partner, a large percentage had never used a condom, and the most common self-reported STI diagnosis was chlamydia.Data results from the MSM survey group indicated the majority of participants (60%) were Micronesian, well-educated with 91% having completed university or college or graduated high school yet unemployment and not living with a regular partner. Most MSM had multiple oral and anal sex partners. A third of those who travelled overseas in the last 12 months (27%) had sex while away; the majority of those were male partners, most did not use a condom and the most common self-reported STI diagnosis was HIV (11%).Data results from the youth survey group indicated that the majority of participants were born in CNMI and currently reside with family. The majority of participants had had sex and a significantly higher proportion of males had had sex than females. Approximately half of the participants had sex without a condom in past 12 months. More females than males had been diagnosed with an STI in the past 12 months chlamydia was the most common STI reported. Youth participants had the highest rates of substance and drug use for betel nut and marijuana and the second highest overall use for tobacco. The majority of youth reported having used drugs (amphetamines, ecstasy, inhalants, hallucinogens and cocaine). The results also revealed that youth were least likely of the three groups to have accurate knowledge on HIV. HIV testing was low across in the youth group. The media has played a large role in educating participants with most participants reporting having heard messages about HIV on TV, then the radio, newspapers and billboards. A large number of youth sought HIV knowledge through the internet.Conclusion: This study presents data on several aspects of risk behavior in the CNMI and documents several risk behaviors (sexual, drug usage and STI history) that provide a starting point for improving preventive healthcare and health promotion programs and increasing healthcare funding in the CNMI. Findings include low HIV testing rates, low HIV knowledge, significant internet usage for HIV/STI information, low off-island travel rates and low rates of condom use. The recommendations proposed can be incorporated into the STI and HIV management programs. This study acknowledges the importance of HIV testing and interventions to improve ST and HIV testing in the CNMI need to be considered. Finally, a recommendation is also made to build on this study to enable further research and testing in the CNMI.

Resumen

Aquaponics has recently emerged on the global scene as a viable form of alternative agriculture. A combination of practices, such as growing and harvesting fish (aquaculture) along with "hydroponically" grown fruits and vegetables, aquaponics integrates traditional agriculture practices with twenty-first century scientific food producing methods. In this thesis, I analyze the literature on aquaponics and connect it firmly within the current social and environmental discussions of the food security discourse among Pacific Island Countries and Territories in order to provide a context of geographical relevance of fish and vegetable producing systems. I also provide data from the Northern Mariana Island of Rota to showcase why and how aquaponics may be a viable option for improving food security within such a context. I then argue that the aquaponic project on the island of Rota helps serve as one potential pathway to improving food security.<br>2015-07-14

Resumen

Over the last 5 years, high school students with disabilities in the Commonwealth of the Northern Mariana Islands (CNMI) have experienced a higher rate of dropout compared to their peers, adding to an ever-widening gap in learning and graduation rates. The rationale for this study was the growing numbers of dropouts among students with disabilities that contribute to high rates of poor performing schools and create a burden on the local and federal government as the CNMI employment rates decline and reliance on the U.S. government for support increases. The purpose of this study was to understand the experiences of students with disabilities who drop out of high school, their perceptions of the learning environment, and the factors that contributed to their decisions to drop out. The conceptual framework was the constructivist theory. To answer what influenced high school students with disabilities to drop out of school and to what extent their perceptions of the constructivist element of belonging, engagement, or advocacy contributed to their decision to drop out, a qualitative case study design was used. Interviews were conducted with 10 former students who dropped out between 2013 and 2016 school years from high schools in the CNMI. Thematic analysis was used for emergent themes. Findings included that students do not receive their high school diploma because school policies prevented them due to age and lack of credits. Poor learning environments hindered students' engagement. Poor teachers' advocacy also hindered students' graduation. The findings can be used by school district leaders and staff in the implementation of effective interventions for improving graduation outcomes for students with disabilities in order for these students to become contributing members of society through gainful employment and enhanced quality of life.

Resumen

This dissertation is based on ethno-historic fieldwork in the Commonwealth of the Northern Mariana Islands (CNMI). In the CNMI there is a complex interaction of customary law within the framework of an American legal system. By studying land disputes in a historical context, I examine how custom is represented, reconfigured, and constructed through law and the dispute process. Law reflects and reproduces ideology through its relationship with the state while at the local level of the case one can analyze the specific ways individuals access, affect, and are affected by the legal system. Courts are a site for the production of meanings that includes state-level forces, such as the law and procedural rules, as well as the impact of individuals, such as attorneys, litigants, and witnesses.

Resumen

The ubiquitous microplastic (MP) pollution is an emerging environmental issue in the marine environment. In this study, historical accumulation trends of MPs in the beach sediments around the Ras Rakan Island of Qatar have been established. The vertical distribution of MPs ranged from 0 to 665 particles/kg with maximum abundance at the surface layer (0–5 cm). Pellets were the dominant type of MPs in the surface sediments, whereas fibers were dominant in the bottom sediments. The polymer composition of MPs was identified using Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) spectroscopy. Polyethylene (PE), polypropylene (PP), polyamide (PA), polyethylene terephthalate (PET), polyvinyl chloride (PVC) and Polystyrene (EPS) were the abundant polymers present in the sediments. High MP concentrations were found in the western and northern parts of the island. The prevailing winds, waves, tides and currents are the forces responsible for the distribution and transport of MPs from the offshore to the island and further to vertical re-distribution as time progresses. The level of MP pollution along the Coast of Ras Rakan Island was higher than that found on the coast of mainland Qatar. This informs that remote islands should also be considered for MP pollution monitoring to assess the risk associated with MP on the biota.

Resumen

The world’s demand to decrease carbon dioxide emissions causes that energy production areas will substantially grow to offshore applications. The growth of offshore wind will be rapid. Elomatic have innovated a solution where the complete wind turbine including float foundation can be built as on-shore construction. The unit including wind turbine installed is floated to offshore location and lowered to seabed as one complete unit. The steel structure used in the float foundation may offer new business potential for the traditional ship building industry used to handling bigger steel constructions. The solution is to major parts eliminating noise to sea life from hammering used in monopile structures. At end of lifespan the whole unit can be re-floated and thus no waste is left in the environment and the used steel can be recycled. While traditional offshore wind farm building requires water depths for the jack-up vessels to operate, the float foundation can be towed with tugboats to also shallower areas, opening up completely new potential areas for wind park construction. Of course this concept can be utilized also in water depths currently in use with for example monopiles. The growth of energy production per farm will require energy conversion units offshore, where transformers, HVDC, or hydrogen and synthetic P2X fuels are produced. A pipeline to shore may be utilized or ships may come and refuel at the offshore production and storage facility. Also in this case technologies such as monopiles or for the bigger footprint man made rock islands can be replaced with the float foundations, once again enabling minor environmental impact with minimal dredging and seabed excavations. The total footprint may also be reduced since no extra lay down space is needed during the construction phase. Northern areas with high energy demands can be expected to grow and in these area solutions withstanding ice conditions is required. Steel constructions used have the benefits over traditional rock island that no repair of ice barriers is needed after each winter, thus reducing the life cycle cost. Moving the construction phase from off-shore to on-shore will reduce cost but also reduce many of the risks associated with offshore construction. When the industry grows the produced electricity is going to be converted into P2X fuels at the offshore location. As a result new logistic chains will be introduced and these can be considered in the design of the energy island. The Float Foundation solution utilizes the know-how from marine and off-shore industries. The huge growth in the green offshore industry is an area where the maritime industry may find new growth potential.

Resumen

Java Island is an active volcanic arc that resides in the southwestern - southern boundary of Sundaland edges. The volcanic arc consists of several volcanism episodes, with a relatively younging trend northward (Late Oligocene to Pleistocene), following the Indo-Australian plates inward migration. In contrast to the prolific neighboring Northwest and Northeast Java Basins in the Northern edges of Java Island; the basin reconstruction and development in the East-West trending depression in median ranges of Java (from Bogor to Kendeng Troughs) are overlooked and lays bare the challenge to the seismic imaging due to the structural complexity of the overthrusted Neogene unit as well as immense Quaternary volcanic eruption covers. On the other hand, oil and gas seepages around the northern and central parts of the Island confirmed the active petroleum generation. Five focused window areas are selected for this study. A total of 1,893 Km sections, 584 rock samples, 1569 gravity, and magnetic data, and 29 geochemical samples (rocks, oil, and gas samples) were acquired during the study. Geological fieldwork was focused on the stratigraphic unit composition and the observable features of deformation products from the outcrops. Due to the scarcity of the Paleogene deposit exposure in the Central-East Java area, the rock samples were also collected from the mud volcano ejected materials in the Sangiran Dome. Both Bogor and Kendeng Troughs are active petroleum systems that generate type II /III Kerogen typical to the reduction organic material derived from transition to the shallow marine environment. The result suggests that these basins are secular from the neighboring basins, The Northwest and Northeast Java Basins, characterized by oxidized terrigenous type III Kerogen. The contrasting subsurface configuration between Bogor and Kendeng Troughs mainly concerns the fold-thrust belt basement involvement and the tectonic shortening effect on the formerly rift basin.

Resumen

Phytoplankton is the base of the marine food web. However, the phytoplankton bloom may deplete the dissolved oxygen and shade aquatic life, and even damages the marine environment. In this study, the satellite-derived sea surface chlorophyll-a concentration (Chl-a) and sea surface temperature (SST) are considered to examine the behavior of the phytoplankton bloom in the sea around the western side of the Luzon Strait in the northeastern South China Sea (SCS). Meanwhile, the related sea surface wind (SSW) is also included to understand the possible mechanism to induce the high Chl-a plume around there. The results indicate that the clear high Chl-a water is mainly around the northeastern SCS in winter, and spreads out westward from the northern edge of the Luzon island, Philippines. The external force of this blooming is probably from monsoon wind driving, the strong and diverse winter monsoon in the Luzon Strait can develop a very clear positive wind stress curl in the northwestern side of Luzon island, and then induce the cold and high nutrient water upward. Meanwhile, the strong winter monsoon can also spread this cold water plume out to develop a very clear and large phytoplankton blooming around there.

Texto completo

Resumen

The unmetamorphosed and nearly undeformed late Mesoproterozoic Borden Basin on northern Baffin Island exhibits sag, rift, and foreland-basin-like phases. A thin, partly subaqueous basal basalt is overlain by mature shallow-marine quartz arenite, upward-deepening siltstone and shale (marking the beginning of rifting), a complex suite of rift-delineated carbonate units containing two dramatic internal unconformities, and a flysch-molasse-like succession containing evidence of sediment derivation from the Grenville Orogen. Geochronological data indicate that deposition of most of the succession took place ca. 1100 to 1050 Ma. One of the carbonate intervals, Nanisivik Formation, is the main host of regional Zn-Pb showings including the past-producing Nanisivik orebody, which formed in the late Mesoproterozoic from low-temperature fluids, and which was emplaced under strong structural and stratigraphic controls. Minimal postdepositional deformation is limited to the emplacement of mafic dykes ca. 720 Ma and repeated reactivation of basement-rooted normal faults.

Resumen

Channel Islands National Park includes the five northern islands off the coast of southern California (San Miguel, Santa Rosa, Santa Cruz, Anacapa, and Santa Barbara Islands) and the surrounding waters out one nautical mile. There are approximately 176 miles of coastline around the islands, about 80% of which is composed of rock. The diversity and undisturbed nature of the tidepools of this rocky coastline were recognized as special features of the islands in the enabling legislation. To conserve these communities unimpaired for future generations, the National Park Service has been monitoring the rocky intertidal communities at the islands since 1982. Sites were established between 1982 and 1998. Site selection considered visitation, accessibility, presence of representative organisms, wildlife disturbance, and safety. This report summarizes the 2018–2019 sampling year efforts (from November 2018 to April 2019) and findings of the Channel Islands National Park Rocky Intertidal Community Monitoring Program. Specific monitoring objectives are 1) to determine the long-term trends in percent cover of key sessile organisms in the rocky intertidal ecosystem, and 2) to determine population dynamics of black abalone (Haliotis cracherodii), owl limpets (Lottia gigantea), and ochre sea stars (Pisaster ochraceus). Objectives were met by monitoring percent cover of core species in target intertidal zones using photoplots and transects, and by measuring size frequency and abundance of black abalone, owl limpets, and sea stars using fixed plots or timed searches. Twelve key species or assemblages, as well as the substrate, tar, have been monitored twice per year at 21 sites on the five park islands as part of the rocky intertidal community monitoring program. Fixed photoplots were used to monitor the percent cover of thatched and acorn barnacles (Tetraclita rubescens, Balanus glandula/Chthamalus spp., respectively), mussels (Mytilus californianus), rockweeds (Silvetia compressa, and Pelvetiopsis californica (formerly Hesperophycus californicus), turfweed (Endocladia muricata), goose barnacles (Pollicipes polymerus) and tar. Point-intercept transects were used to determine the percent cover of surfgrass (Phyllospadix spp.). Information about size distribution (i.e., “size frequency” data) was collected for owl limpets in circular plots. Size distribution and relative abundance of black abalone and ochre sea stars were determined using timed searches. The maximum number of shorebirds and pinnipeds seen at one time were counted at each site. The number of concession boat visitors to the Anacapa tidepools was collected and reported. All sites were monitored in 2018–2019. This was the third year that we officially reduced our sampling interval from twice per year (spring and fall) to once in order to streamline the program and allow for the implementation of additional protocols. Weather conditions during the site visits were satisfactory, but high wind coupled with strong swell and surge limited or prevented the completion of some of the abalone and sea star searches. The percent cover for most key species or assemblages targeted in the photoplots was highly variable among sites. Mussel (Mytilus californianus) cover remained below average at Anacapa and Santa Barbara Islands. Record or near record low abundances for Mytilus were measured at Middle West Anacapa (Anacapa Island), Harris Point (San Miguel Island), Prisoner’s Harbor (Santa Cruz Island), and Sea Lion Rookery (Santa Barbara Island) sites. The only site that appeared to have above average Mytilus cover was Scorpion Rock on Santa Cruz Island. All other sites had mussel cover near or below the long-term mean. Qualitatively, Mytilus recruitment appeared low at most sites. Both rockweed species, Silvetia compressa and Pelvetiopsis californica (formerly Hesperophycus californicus), continued to decrease markedly in abundance this year at the majority of sites compared to combined averages for previous years. Fossil Reef and Northwest-Talcott on Santa Rosa Island, Sea Lion Rookery on Santa Barbara Island, and South Frenchy’s Cove on Anacapa Island were the only sites that supported Silvetia cover that was near the long-term mean. No sites exhibited above average cover of rockweed. Extremely high levels of recruitment for Silvetia and Pelvetiopsis were documented at many sites. Most sites exhibited marked declines in S. compressa abundances beginning in the early 2000s, with little recovery observed for the rockweed through this year. Barnacle (Chthamalus/Balanus spp.) cover fell below the long-term means at all islands except Anacapa, where barnacle cover was slightly above average. Endocladia muricata abundances remained comparable to the grand mean calculated for previous years at Santa Barbara, Santa Cruz, and Santa Rosa Islands, while cover of the alga decreased slightly below the long-term means at Anacapa and San Miguel Islands. Black abalone (Haliotis cracherodii) abundances at the islands remain less than one percent of 1985 population levels. Zero abalone were found throughout the entire site at Landing Cove on Santa Barbara Island and South Frenchy’s Cove on Anacapa Island. Above average abundances relative to the long-term mean generated from post-1995 data were observed at all but five sites. Juvenile black abalone were seen at all islands except Santa Barbara. Ochre sea star (Pisaster ochraceus) populations crashed in 2014 at all monitoring sites due to Sea Star Wasting Syndrome, an illness characterized by a suite of symptoms that generally result in death. The mortality event was widely considered to be the largest mortality event for marine diseases ever seen. Beginning in June 2013, the disease swiftly and significantly impacted P. ochraceus (among other species of sea stars) populations along the North American Pacific coast from Alaska to Baja California, Mexico. By the beginning of 2014, P. ochraceus abundances had declined by >95% at nearly all Channel Islands long-term intertidal monitoring sites, in addition to numerous other locations along the West Coast. At various times during the past decade, extremely high abundances (~ 500 P. ochraceus) have been observed at multiple sites, and most locations have supported >100 sea stars counted during 30-minute site-wide searches. This year, abundances ranged 0–13 individuals per site with all but one site having fewer than 10 P. ochraceus seen during routine searches. Insufficient numbers of sea stars were seen to accurately estimate the size structure of P. ochraceus populations. Only two juveniles (i.e., <50 mm) were observed at all sites combined. Giant owl limpet densities in 2018–2019 were comparable or slightly above the long-term mean at seven sites. Exceptionally high densities were measured at Northwest-Talcott on Santa Rosa Island, Otter Harbor on San Miguel Island, and Willows Anchorage on Santa Cruz Island. The sizes of L. gigantea this year varied among sites and islands. The smallest L. gigantea were observed at Otter Harbor followed closely by Willows Anchorage and Anacapa Middle West, and the largest were seen at Northwest-Talcott. Temporally, the mean sizes of L. gigantea in 2018–2019 decreased below the long-term mean at each island except Anacapa. Surfgrasses (Phyllospadix spp.) are typically monitored biannually at two sites each on Santa Cruz and Santa Rosa Islands. Beginning in 2015, all transects at each of the monitoring sites were only sampled once per year. At East Point on Santa Rosa Island, the conditions were not conducive to sampling the surfgrass transects, but qualitatively, percent cover of surfgrass appeared to be near 100% on all three transects. Relative to past years, cover of surfgrass increased above the long-term mean at Fraser Cove on Santa Cruz Island, fell slightly below the mean at Trailer on Santa Cruz Island, and remained approximately equivalent to the mean at the two Santa Rosa Island sites. Overall, the abundance and diversity of shorebirds in 2018–2019 at all sites appeared similar to observations made in recent years, with the exception of elevated numbers of brown pelicans (Pelecanus occidentalis) observed at East Point on Santa Rosa Island. Black oystercatchers (Haematopus bachmani) were the most ubiquitous shorebird seen at all sites. Black turnstones (Arenaria melanocephala) were not common relative to past years. Pinniped abundances remained comparable in 2018–2019 to historical counts for all three species that are commonly seen at the islands. Harbor seals (Phoca vitulina) were seen in the vicinity of eight sites this year. As in past years, harbor seals were most abundant at Otter Harbor and Harris Point on San Miguel Island. Elephant seals (Mirounga angustirostris) were seen at six sites during the year, where abundances ranged 1–5 individuals per location. California sea lions (Zalophus californianus) were common at Santa Barbara Island; 117 individuals were observed at Sea Lion Rookery. Sea lion abundances were higher than usual at Harris Point (N = 160) and Otter Harbor (N = 82) on San Miguel Island. Relative to past years, abundances this year were considered average at other locations.
