water-column

Five years ago the National Academy of Sciences issued a nearly 400-page study on oil dispersants, which cautioned, "In many instances where a dispersed plume may come into contact with sensitive water-column or benthic organisms and populations, the current understanding of key processes and mechanisms is inadequate to confidently support a decision to apply dispersants."

In the Norwegian Sea and the Atlantic (southwest) part of the Barents Sea, thermally-derived water-column stability is established in late May to early June [22].

A shift from an ice-associated bloom to a water-column bloom in the central and northern Bering Sea shelf as a result of ice retreat provides the potential for development of the plankton community at the expense of the benthic community [18].

However, current estimates of water-column denitrification also vary widely (from 65 to 150 Tg N a-1).

One would expect the extent of water-column denitrification to be better constrained due to the geographical restriction of vigorous denitrification to just a few well-demarcated sites - within the oxygen minimum zones (OMZs) of the eastern tropical Pacific and the northwestern Indian Ocean (Arabian Sea).

The most important loss terms are sedimentary and water-column denitrification.

One can get at the weight of water, thank goodness! and it has been ascertained that our water-column will weigh fifteen pounds if the tube is a square inch in size.

The spring spouted again at seven o'clock in the evening, ascended higher than at noon, and brought up some stones, which looked like black spots and points in the white frothy water-column.
