Extract

In July, 1935, a cruise was made in Col. E. T. Peel's yacht St. George to study the distribution of certain plankton animal indicators in the mouth of the English Channel.

Three bodies of water were clearly shown by their plankton content:

(1) water characterised by the presence of Sagitta elegans, Clione, Themisto graclipes, Euphausian larvæ, Stephanomia and Aglantha; (2) Biscay water, on this occasion characterised by Noctiluca and a paucity of zooplankton; and (3) Channel water characterised by the presence of Sagitta setosa and absence of other indicators.

It has been shown that the study of certain plankton animals should prove of help in understanding the hydrography of the Channel mouth region.
