Parasitized amphipods were generally found lower in the watercolumn than control amphipods (fig. 2). On the shelf, the oceanic species were absent: the dominant fish in the watercolumn was antarcticum. The most important ecological features in differentiating tadpole species were position in the watercolumn, time of occurrence and water depth. Floating or motile ones in the watercolumn have a greater chance of being incorporated into the ice, if water from below fills openings. These activities could contaminate the water body and disturb the watercolumn, microbial communities, and sediments. The unexpanded egg has a density significantly greater than that of water and sinks rapidly to the bottom of a watercolumn. Autochthonous carbonates can rapidly precipitate out of the watercolumn in shallow, hard-water tropical lakes, thus diluting pollen present in the lake sediment. Although not age diagnostic, it demonstrates either stratification within the watercolumn or dysoxia/anoxia within the top layer of sediments. The copepodid is initially free living in the watercolumn and finds and attaches to the host. The watercolumn remained thermally stratified throughout the remaining record. The absence of fauna suggests a dearth of graptolites in the overlying watercolumn caused by adverse environmental conditions. The high-diversity assemblages may preserve complex ecological associations of graptolites that existed in the watercolumn during 'graptolite-friendly' environmental conditions. This facies architecture suggests settling of size- and density-graded ash through the calm watercolumn. Its dilution effect stabilises the watercolumn, increases the retention of nutrients washed off the islands and leads to periodic phytoplankton blooms. In the ponds, the fish are gregarious and found in shoals, and they occupy the entire watercolumn. Turbulent mixing leads to entrainment of ' background ' material from the ambient watercolumn within this rising plume. Productivity may have been greatly affected by ash transported through the watercolumn or an attendant change in seawater chemistry. The series of tows on the bottom revealed that diversity and biomass were enormous relative to the watercolumn. Position in the watercolumn was the most informative ecological variable in discriminating among tadpole species. These flashes of activity are then followed by longer periods of drifting or sinking in the watercolumn. This unit was deposited during a time when the lake was oxygenated throughout the watercolumn and no water-column stratification was present. By contrast, the accumulation of opal is strongly influenced by dissolution in the watercolumn. These suggest different ecological associations of graptolites in the overlying watercolumn cor responding to local environmental changes. Digenean parasites produce large numbers of non-feeding and motile cercariae that disperse within the watercolumn and seek out the fish host. The reverse would be called for in the case of hosts living ' up ' in the watercolumn. The density in the ocean is determined by temperature, salinity, and pressure, with most of the vertical variation within a watercolumn being due to the pressure. Organic matter sources to the watercolumn and surficial sediments of a marine bay. Evidence for gammacerane as an indicator of watercolumn stratification. A further, requirement, of course, is to equip such a vehicle with the appropriate sensors to prospect for and detect hydrothermal signals in the watercolumn. Infected amphipods were found to exhibit significantly lower levels of activity and to occur significantly lower in the watercolumn than uninfected controls during both periods. Within the 'open marine biotope', differences in the associations of graptolites preserved at individual horizons in the rock sequence suggest different graptolite ecologies in the overlying watercolumn. In the ocean, typically varies by at most a few per cent over the vertical extent of a watercolumn. Such activity will increase as seawater temperature rises and could conceivably lead to a greater intake of pollution from oil contained in the watercolumn.
