Full textAbstract:
In 2016 and 2017, the Utah Geological Survey partnered with the U.S. Bureau of Land Management to conduct a paleontological inventory of the Morrison Formation south and west of Blanding, Utah, along the eastern margin of the Bears Ears National Monument. The Morrison in this region is critical to understanding Upper Jurassic stratigraphy across the Colorado Plateau because it is the type area for the Bluff Sandstone, Recapture, Westwater Canyon, and Brushy Basin Members of the Morrison Formation, which are the basis for nomenclature in New Mexico and Arizona as well. Researchers have disagreed about nomenclature and correlation of these units, which transition northward in the study area into the Tidwell, Salt Wash, and Brushy Basin Members. Numerous vertebrate localities make inclusion of the Bluff Sandstone and Recapture Members in the Middle Jurassic San Rafael Group, as suggested by some previous workers, unlikely. The Salt Wash Member does not separate the Bluff Sandstone and Recapture Members at Recapture Wash, but sandstone lenses of Salt Wash facies occur higher in northern Recapture exposures. Northward, along the outcrop belt east of Comb Ridge, the Bluff-Recapture interval thins, interlenses, and pinches out into the Tidwell and lower Salt Wash, with the main lower sandstone interval of the Westwater Canyon merging northward into the upper Salt Wash Member.
The partly covered, 1938 type section of the Brushy Basin Member is identified along Elk Mountain Road at the southern end of Brushy Basin. We describe a detailed, accessible Morrison Formation reference section about 11.2 km (7 mi) to the south along Butler Wash. There, 81.68 m (268 ft) of Brushy Basin Member is well exposed along a road between the top of the Westwater Canyon Member and the base of the Lower Cretaceous Burro Canyon Formation. We informally call the upper sandstone bed(s) of the Westwater Canyon Member that cap mesas and benches in the region “No-Mans Island beds.” Smectitic mudstones between the No-Mans Island beds and the main sandstone body of the Westwater Canyon suggest that the Salt Wash-Brushy Basin contact to the north may be somewhat older than the base of the Brushy Basin Member as originally defined in its type area. Determining whether the No-Mans Island beds pinch out to the north or are removed by erosion below the regional basal Brushy Basin paleosol requires further research. Several significant fossil vertebrate and plant sites have been documented in the Brushy Basin type area. Newly identified volcanic ashes provided zircons for U-Pb ages of 150.67 ± 0.32 Ma from near the top of the Brushy Basin Member and of 153.7 ± 2.1 Ma and 153.8 ± 2.2 Ma for two zircons in lower part of Recapture Member. At the top of the Brushy Basin Member, ferruginous paleosols commonly overlying conglomeratic sandstone are speculated to be of Early Cretaceous age (detrital zircon age pending) and are assigned herein to the Yellow Cat Member of the Burro Canyon Formation. These iron-rich paleosols suggest wetter climatic conditions during the Jurassic-Cretaceous transition in the Blanding basin.

Summer heat waves inNorthern California continue to break records for extreme temperatures and put vulnerable urban populations at increasing risk for adverse health impacts. An analysis of Landsat land surface temperature data was conductedin this study to better understandthe geography and demographics of extreme urban heat events in Santa Clara County and the city of San Jose, California. The influence of several urban cover features including streets/roadways, parcel sizes and densities, impervious surfaces, and irrigated shrub/lawn cover were determined for county-wide surface heat patterns in early August 2020. Results showed that the surface temperature of the largest impervious (high-asphalt) surface features was significantly higher, at a mean value of 45°C, than the majority of the other areas across the entire county. In contrast, urban tracts with even partial coverage by irrigated green lawns, shrubs, and small trees had notable cooling effects on summer surface temperatures. Social demographic and household population variables from the U. S. Census Bureau were correlated against satellite surface temperature by census tract to reveal significant associations of family structure and education levels with local neighbourhood heat conditions.

Full textAbstract:
The Klong U-Tapao watershed is the main source of water supply for agriculture, industry, and household consumption of the Songkhla province and it frequently contributes serious problems to lowland areas, particularly flood and soil erosion. Therefore, land use and land cover (LULC) scenario identification for optimum water yield and sediment retention ecosystem services are necessary. In this study, LULC data in 2010 and 2017 were firstly classified from Landsat data using random forests classifiers, and they were then used to predict LULC change during 2018 –2024 under three different scenarios by CLUE-S model. Later, actual LULC data in 2017 and predictive LULC data of three scenarios were further used to estimate water yield and sediment retention services under the InVEST and LULC scenario for optimum water yield and sediment retention ecosystem services were finally identified using the ecosystem service change index (ESCI). The result of the study showed the major increasing areas of LULC types during 2010–2017 were rubber plantation and urban and built-up area while the major decreasing areas of LULC classes were evergreen forest and miscellaneous land. In addition, the derived LULC prediction of three different scenarios could provide realistic results as expected. Likewise, water yield and sediment retention estimation of three different scenarios could also provide expected results according to characteristics of scenarios’ definitions and climates, soil and terrain, and LULC factors. Finally, LULC of Scenario II was chosen for optimum water yield and sediment retention ecosystem services. In conclusion, the integration of remote sensing technology with advanced classification methods and geospatial models can be used as proficient tools to provide geospatial data on water yield and sediment retention ecosystem services from different scenarios.

Full textAbstract:
When the last U.S. Census canvassed Slab City, a remote, self-governed community of artists, retirees, anarchists and homeless people in southern California’s desert, most of its residents claimed ownership of the plots they occupied as “free and clear.” And yet Slab City itself occupies land that is public, as firm in this designation as the resolve of those who live there. Often called the “last free place,” this square-mile plot is one of the remaining Section 36 areas, which were originally reserved for the state’s public schools when each township was laid out by the National Ordinance’s land surveys that blanketed the American West in an invisible but all-encompassing grid. Consequently, the state of California hosts an array of one-square mile pockets of land. Among these, Slab City is a camp that bears the ongoing question of how land—environmentally inhospitable yet relatively hospitable in its public status—might host practices of self-determination, self-regulated community, and national identity. Veritable blind spots of land management, Section 36 areas contrast other more regulated, though comparable, practices on public and private lands. The Bureau of Land Management oversees Long Term Visitor Areas where campers can park trailers across vast territories for extended periods of time, and Walmart plays host to cross-country travelers who overnight in its parking lots—a permutation of recreational camping known as boondocking. But what happens in the absence of oversight? In places where the campsites become permanent? In times when those living there have arrived not only by choice but also in many cases out of necessity? Legacies of a country’s organizational matrix, Section 36’s pockets of land linger as residual pieces of frontier mythologies, as testaments of the arbitrariness of the grid and its land policies, and as fertile ground for alternative practices of adapting to inhospitable environments and making home in improvised communities. This essay seeks to understand how Section 36 land hosts contemporary intersections of public space and freedom.

Full textAbstract:
This study was conducted to assess the water quality affected by different land use patterns in U Minh Ha National Park, Ca Mau, Vietnam. This study determined the water quality characteristics in three land use types (Acacia hybrid, planted melaleuca cajuputi, and natural melaleuca cajuputi) at different plant ages on two acid sulfate soil layers in the rainy season (8/2018) and dry season (4/2019) using nine water quality parameters. Multivariate statistical analyses were applied to evaluate the correlation and spatial and temporal variations in the water quality. The study results showed that the water quality in S-ASS was more polluted than that in D-ASS, characterized by low pH; the EC, organic matters (BOD and COD), nutrients (N-NH4+ and N-NO3−), and metal ions (Al3+ and Fe3+) were high; and the EC, BOD, COD, Al3+, and N-NO3− were determined high in D-ASS. The NMC area was noted to have high concentrations of organic matters and nutrients, while the factors specific to acidic soil were found to be higher in the AH and PMC areas. The water quality in the rainy season tended to be more polluted than that in the dry season. The cluster analysis grouped the land use patterns on S-ASS and D-ASS in both seasons into four groups, with a clear similarity between the wet and dry seasons in the areas at various plant ages. The seasonal variations of the water quality of the three land use types were distinguished by the main parameters, including pH, EC, BOD, N-NO3−, and Al3+ (S-ASS) and EC, BOD, N-NO3−, N-NH4+, and Fe3+ (D-ASS). Therefore, there is a need for better water management measures in the rainy season and focus on the key parameters causing water quality variations in each area. The findings in this study provided important information for the future water quality monitoring for both agricultural production and conservation in the national park.

Full textAbstract:
A ditch system was designed, constructed, and evaluated on a 1-km2 experimental plot in peat-covered wetland in Slave Lake Forest, Alberta, Canada, during 1981–1985. The purpose of the experiment was the development of techniques and procedures for the design of drainage systems for water-table control in large tracts of forested peatlands of northern Alberta, in order to enhance tree growth. The technical objective of the envisaged drainage systems is to prevent the water table from rising above a specified depth, or drainage norm νm, below the land surface, for a continuous time interval longer than a specified flood duration limit λm, during the growing season. The position of the water table and the rate and amplitude of its fluctuations in a ditched area depend on the environmental parameters (K, hydraulic conductivity; S*, field coefficient of water-table response to precipitation; z, depth to the first effectively impermeable stratum; P, pattern of daily rainfall) the design parameters (L, ditch spacing; u, ditch depth), and at later stages of drainage, the effect of the tree stand. The objective of the design is, therefore, to determine appropriate values of L and u as functions of the environmental parameters to be used in the construction of operational drainage systems. The central component of the design procedure is the optimization of synthetic hydrographs. The synthetic hydrograph is a graphical representation of calculated time series of the water table's fluctuations reflecting the effect of discrete rainfall events under specified drainage conditions. Synthetic hydrographs were calculated with the U.S. Bureau of Reclamation drain spacing formula adapted here for daily rainfall events and ranges of estimated environmental and assumed design parameters. An experimental drainage system was constructed with preliminary design parameters that were expected to satisfy the criteria νm and λm. In addition, 14 water-table observation wells and a rain gauge were installed and operated for two summers. Synthetic hydrographs were then computed using the actually implemented design parameters, the actual rainfall pattern and a fixed z value, leaving K and S* as the only unknown variables. Those K and S* values giving the best approximation of calculated to observed hydrographs were considered to represent the effective field values and were used in turn to calculate the final design parameters, again by hydrograph matching. Final values for K and S* for two subregions of the experimental plot were found to be K1 = 0.37 m/d, S1* = 0.13; and K2 = 0.26 m/d, S2* = 0.11. For subregion No. 2 a ditch spacing L = 25 m and ditch depth u = 0.9 m satisfy the stipulated drainage norm νm = 0.4 m and flood duration limit λm = 14 days, using P1962, which was the wettest year for the last 28 years in the region.

"Challenges in updating habitat suitability models: An example with the lesser prairie-chicken." PLOS ONE 16, no. 9 (September 20, 2021): e0256633. http://dx.doi.org/10.1371/journal.pone.0256633.
Full textAbstract:
Habitat loss from land-use change is one of the top causes of declines in wildlife species of concern. As such, it is critical to assess and reassess habitat suitability as land cover and anthropogenic features change for both monitoring and developing current information to inform management decisions. However, there are obstacles that must be overcome to develop consistent assessments through time. A range-wide lek habitat suitability model for the lesser prairie-chicken (Tympanuchus pallidicinctus), currently under review by the U. S. Fish and Wildlife Service for potential listing under the Endangered Species Act, was published in 2016. This model was based on lek data from 2002 to 2012, land cover data ranging from 2001 to 2013, and anthropogenic features from circa 2011, and has been used to help guide lesser prairie-chicken management and anthropogenic development actions. We created a second iteration model based on new lek surveys (2015 to 2019) and updated predictors (2016 land cover and cleaned/updated anthropogenic data) to evaluate changes in lek suitability and to quantify current range-wide habitat suitability. Only three of 11 predictor variables were directly comparable between the iterations, making it difficult to directly assess what predicted changes resulted from changes in model inputs versus actual landscape change. The second iteration model showed a similar positive relationship with land cover and negative relationship with anthropogenic features to the first iteration, but exhibited more variation among candidate models. Range-wide, more suitable habitat was predicted in the second iteration. The Shinnery Oak Ecoregion, however, exhibited a loss in predicted suitable habitat that could be due to predictor source changes. Iterated models such as this are important to ensure current information is being used in conservation and development decisions.

Full textAbstract:
In Northern China, many regions and cities are located in semi-arid regions, and groundwater is even the only source of water to support human survival and social development. Affected by human activities, the Bashang (BS) region (including Zhangjiakou City and part of Xilin Gol League) have showed a significant decline in groundwater levels in recent years. However, in the BS region, the causes for the decline in groundwater level were not clear. In this study, we used time series of multi-source data Moderate Resolution Imaging Spectroradiometer (MODIS), Gravity Recovery and Climate Experiment (GRACE) and Global Land Data Assimilation System (GLDAS) to analyze vegetation and groundwater changes based on linear regression models. The variation trends of NDVI (Normalized Difference Vegetation Index, derived from MODIS) and GWSA (groundwater storage anomaly, derived from GRACE and GLDAS) indicated the increasingly better vegetation in the agriculture planting areas, partially degraded vegetation in the grassland, and the declining groundwater level in the whole study region. In order to assess the impact of human-induced factors on vegetation and groundwater, the R U E s e a s o n a l calculation model was proposed based on RUE (rain use efficiency) in this study. The R U E s e a s o n a l calculation results showed that human-induced factors promoted the growth of vegetation in agricultural areas and accelerated the consumption of groundwater. In addition, we also obtained temporal and spatial distributions of human activities-affected regions. The area affected by human-induced factors in the south-central study area increased, which accelerated the decline in groundwater levels. From bulletin data, we found that the increasing tourists and vegetable production are respectively the most important factors for the increased consumption of urban water and agricultural water. Based on multi-source data, the influences of various human-induced factors on the ecological environment were explored and the area affected by human-induced factors was estimated. The results provide the valuable guidance for water resource management departments. In the BS region, it is necessary to regulate agricultural water use and strengthen residential water management.

Health management of a machine, such as a gas turbine engine, offers the potential benefits of efficient operations planning and the reduced cost of ownership. It requires a tight integration of major health management functions, such as trending, failure identification, forecasting, life prediction, operations and maintenance planning. This paper introduces a suite of plug-in tools that enhance the condition monitoring and health management capabilities of operational (or legacy) systems. One of these systems is the U. S. Air Force Comprehensive Engine Trending and Diagnostics System (CETADS), which has been used as the baseline for the development of the tools. These tools are collectively called the Intelligent Condition-based Engine/Equipment Management System (ICEMS). These tools are configured as software modules, which can be incorporated into an operational health management system individually or as a group. ICEMS modules implement the advanced algorithms containing artificial intelligence, statistical, model-based analysis techniques, and RCM practices. Although these modules have been developed and tested using data from the Pratt & Whitney F100-PW-220 engine in service at Luke Air Force Base, the modules are also generalized to cover many generic machines (or equipment).

It has exceptional landscape conditions, highly productive lands, and a large percentage of the water reserve that supplies the region and the country, giving the territory an economic center character since the colony. These physical values make part of collective imagination as a recreation area and an opportunity for development in the 1960s, according to the construction of large national infrastructure works. At the same time, it was object of armed conflict in the 1980s and 1990s, and more recently, directly related to the spatial dynamics of the region: unplanned urban expansion, changes in land use and vegetation cover, with effects on the cultural landscape. In a post-conflict situation, the economic strategies of different actors trust on tourism as a social-spatial management strategy to improve the territory. However, the identity of rurality shows spatial imbalances without recognizing elements of historical construction whose legacies must be revealed to ensure equitable development. To do this, we propose an approach from the cultural landscape in a revision of the historical, symbolic and relational transformation through five systems (anthropic, productive, political, symbolic and spatial), analyzing competitiveness, tourism, landscape and social management, in different scales and during three historical moments.

Full textAbstract:
The area of the town of Mailuu Suu, Kyrgyzstan, is polluted by radionuclides and heavy metals in tailing dumps and heaps resulting from the historic exploitation of U-mines in the Mailuu Suu area in Kyrgyzstan. Radioactive substances are stored in 23 tailings and 13 mining debris heaps situated along the Mailuu Suu River. The objective of the EC-TACIS funded project is to evaluate and prepare measures to be taken by the authorities to reduce the radiological exposure of the population and to prevent environmental pollution by radionuclides and heavy metals in case of loss of tightness of dams and damage to dumps and heaps from mining and milling by land and mudslides and to propose sustainable remedial options, accepted by the public. The actual radiological situation is of no immediate concern for most of the population of Mailuu Suu. From the gamma radiation monitoring campaign (monitoring network in Mailuu Suu, Kara Agach and vicinity), it showed that the background radiation is 100–120 nSv/h. On the tailings radiation is on average twice background. The average outside and in-house radon concentration is 175 Bq/m3. In 3 of the houses monitored at Kara Agach the radon level is between the exemption limit for new (200 Bq/m3) and old (400 Bq/m3) houses. The concentration of uranium in the Mailuu Suu river water is far below the exemption limit for drinking water set in Kyrgyzstan. Additional dose from irrigation with Mailuu Suu river water is small in actual conditions (< 0.1 mSv/year). However, there is an important possibility that triggered by an eathquake or a landslide, (part of the) tailing(s) content may be directed to the river Mailuu Suu. Doses to the affected population may increase to multiple ten mSv per annum. Given the actual limited stability of Tailing N°3, the potental of such a disaster to occur isnon-neglegible. To impede the consequences of a potential disaster, under the TACIS project different remedial options are evaluated for Tailing 3 including in situ stabilisation and tailing translocation. Also more global remedial options for the Mailuu Suu River valley are studied (translocation of other tailings, tunnel to deviate river, partial protection of river from landslide blockage). It was proposed to acquire a phased approach in time performing urgent limited stabilisation options for Tailing 3, improve the stability of the Tailing 3 by COLMIX-columns in the medium term, while investigating and evaluating further two long-term remedial options: the translocation of the tailings and the long-right-bank river diversion tunnel.

Full textAbstract:
The meaningful United States regulation of onshore oil and gas field waste/soil commenced in the mid 1980’s in response to a series of state, federal, industry and international initiatives. Most initiatives centered on the design, construction and operation of earthen pits used in the exploration and production of oil and gas (E&P). Prior to this time, earthen pits were constructed as needed by the operator and used in all phases of E&P activity. Chief concerns of the regulators were focused on what had gone into pits historically, what was going into them currently and was the E&P exemption excluding high volume E&P wastes from the Resource Conservation and Recovery Act (RCRA) regulations justified. Several investigations, including the comprehensive field study by the Environmental Protection Agency in 1987, determined E&P wastes are ostensibly non-hazardous. EPA concluded regulation of E&P wastes under RCRA Subtitle C was not necessary. To this day there is no U. S. federal regulatory program with exclusive jurisdiction over exempt E&P wastes. Other studies, primarily industry and academic, focusing on land limiting constituents, management practices and pit closure strategies revealed sodium salts and petroleum hydrocarbon in the form of diesel range organics were the primary limiting constituents. One state, Louisiana, adopted the technical aspects of these studies and developed a comprehensive regulation known as Statewide Order 29-B, which was based on the concept of limiting constituents and defined post closure performance standards. These standards limited salinity, sodicity, total metals and total petroleum hydrocarbon (oil & grease) with values varying with respect to landform, land use and closure technique. Other states have adopted some of the concepts and criteria advanced under 29-B but none are as comprehensive. Obviously there is a need to control what goes into pits and how pits should be closed. The industry would best be served by adopting the concepts and standards set forth in the Louisiana 29-B regulation. A few of the provisions could be changed to make it more palatable to industry without sacrificing the protection afforded human and animal health, safety and the environment. Internationally, particularly countries in South America embraced USEPA protocol for testing characteristically hazardous wastes, but 1) without the framework to handle the relatively large volume of non-hazardous E&P waste generated and 2) no regulations or protocols for on-site waste management. Several operators, although partners with state owned oil companies, on their own volition, applied the concepts and standards under Louisiana’s 29-B to rainforests in South America and rice paddies in Indonesia. Canada and European oil and gas producing countries have developed stringent standards not based on science, which favor costly treatment technologies. Generally, these countries prohibit cost effective on-site waste management and closure techniques. This paper traces the evolution of waste/soil remediation within the United States and internationally. We trace the progress as a function of time; the impetus for regulation; and probable future controls.
