Abstract:

Aircraft measurements are analysed from the “First Lagrangian” of the Atlantic Stratocumulus Transition Experiment (ASTEX) from south east of the Azores Islands. In this experiment, Lagrangian strategy was used and the marine air mass, that advected southward, was followed during 12 to 14 June 1992. During the experiment, the stratocumulus clouds transitioned into thin and broken stratocumulus with cumulus cloud penetrating from below. To characterise the vertical structure in the marine boundary layer the buoyancy ﬂuxes, the variances, the turbulent kinetic energy, the momentum ﬂuxes and humi

Abstract:

The vertical structure in the coastal marine atmosphere has been investigated using data from aircraft measurements performed along the Blekinge coast. The present data are from the third of October 1990. The main feature is fairly homogeneous horizontal conditions and a subceeing boundary layer which lowers from 600 meters down to about 50 meters during the day. The turbulence were found to be in a decreasing state. The turbulence parameters were normalized using normal stationary scaling, in order to compare with other results.

Abstract:

Marine viruses are the most numerous biological entities in the ocean, with an estimated abundance of 4 x 1030. They merit study not only because of their sheer abundance, but also because of the role they play in the Earth's biogeochemical cycles. Viral lysis of bacteria redirects the flow of nutrients among marine microbes, which ultimately affects the efficiency of the biological pump. Viral diversity is important because most viruses are host-specific. In preying on a certain type of bacteria, viruses affect the diversity and structure of the bacterial community, leading to changes in carb

Atmospheric aerosols are a highly relevant component of the climate system affecting atmospheric radiative transfer and the hydrological cycle.

A total of 45 species of amoebae were isolated, about one third of which were new to science. One Salton Sea species, Platyamoeba pseudovannellida n.sp. was found to survived over the range 0 - 150 ‰.

Abstract:

<p>Oceans cover about 70% of the earth’s surface. They are the largest source of the atmospheric water vapour and act as enormous heat reservoirs. Thus in order to predict the future weather and climate it is of great importance to understand the processes governing the exchange of water vapour and heat between the ocean and atmosphere. This exchange is to a large extent mediated by turbulent eddies. Current numerical climate and weather forecast models are unable to resolve the turbulence, which means that the turbulent exchange needs to be simplified by using parameterizations. </p><p>Tower

Abstract:

Concentrations of methanesulfonate (MSA), nitrate (NO3-) and non-sea-salt sulfate (nssSO4-) were compared for five different air mass categories encountered during a 1993 NOAA cruise in the North Atlantic. NO3- and nssSO4- concentrations were highest during air masses originating from Europe and the United States. MSA concentrations increased with increasing latitude. Dry deposition fluxes for the three analytes were compared with respect to particle size and air mass category. MSA had a mixed distribution with particle size, nssSO4- was found primarily on smaller particles (<1.1 μm radius), a

Abstract:

Cyclic variations in skeletal structure of long-lived reef corals produce annual density bands evident by X-radiography and X-ray computed tomography. The chemical composition of the calcium carbonate (CaCO3) skeleton and the chronological reliability of these high-density (HD) and low-density (LD) bands can provide accurate records for reconstruction of long-term climatic and ecological conditions. Due to variability across coral taxa, the architectural variations responsible for density banding are not completely understood. The western Atlantic/Caribbean reef coral, Diploria strigosa, is th

Abstract:

Tissue samples from twenty bottlenose dolphins from a stable, residential community of coastal dolphins in the western Gulf of Mexico were analyzed for toxic PCB congeners and chlorinated pesticides. The tissues analyzed (blubber and melon) were from known individuals in a long-term (27+ y) study that stranded and were recovered for necropsy. Substantial demographic data were available on these individuals and utilized in the analysis of maternal transfer of organochlorines to young. The male dolphins in this study were shown to accumulate organochlorine contaminants with age. In female dolphi

Abstract:

Blue tilapia, Oreochromis aureus were cultured from fingerling through maturation, in outdoor tanks, at varying salinities, for a period of nine months, from September 19, 1997 to June 19, 1998. Twelve tanks were used for testing four different salinities, with three replicates each. Each tank had a surface area of 0.8 m2, a water depth of 48cm, and held a volume of 350 liters. Each tank was stocked with ten O. aureus, with a total mean weight of 100 grams, and fed 5% to 10% body weight per day depending on size throughout the study. Salinity was the only induced variable throughout the experi

Full text

Abstract:

The response of diel extracellular α and β-glucosidase activity to in situ dissolved carbohydrates was explored in coastal marine waters. The hypothesis being tested was to determine whether natural substrate could regulate enzyme activity. Relative enzyme activity was determined using artificial 4-methylumbelliferone (MUF) substrate derivatives at low substrate concentrations (300 nM). Disssolved carbohydrate concentrations were measured using the 3-methyl-2-benzothlazolinone hydrazone hydrochloride (MBTH) method: a spectrophotometric determination of monosaccharide concentrations.

Abstract:

The distribution and abundance of ghost crab (Ocypode quadrata) burrows on Hillsboro Beach, Florida, and their relationship to, and effect on sea turtle nests were documented at three control sites and three experimental sites from April 1994 through October 1994. The three experimental sites were located immediately to the east of three open beach sea turtle hatcheries and the control sites were established on nearby open beaches. The purpose of this work was 1) to determine if a larger population of O. quadrata occurred near sea turtle hatcheries than elsewhere along Hillsboro Beach and 2) t
