Publisher's Synopsis
Excerpt from British Antarctic Expedition 1907-9, Under the Command of Sir E. H. Shackleton, C. V. O, Vol. 1: Reports on the Scientific Investigations; Biology
In summer the collecting was still simpler. The weed could be washed in the lake water without the need for preliminary thawing.
In this way we collected continually from the shallow lakes. There were some deeper lakes, which, as it proved, did not melt in summer. In Clear Lake a hole was dug through the ice. We came on water at a depth of about four feet. Here we dredged on the lake bottom, at a depth of seventeen feet. There was a quantity of vegetation brought up, but it was discoloured and dead, and there was no living thing upon it.
Late in the winter, Priestley sunk a shaft in the southern portion of Blue Lake, for the purpose chie?y of observing the temperatures of the ice. At a depth of nine feet some scraps of weed were got, and when thawed a number of living animals were found on it. At a depth of fifteen feet we came on the bottom of the lake, which was here composed of angular fragments. These were covered by a continuous film of yellow weed, and on this also there were numerous living things.
