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. See all examples of water column These examples are from corpora and from sources on the web.
