OverviewExcerpt from Department of Marine Biology of the Carnegie Institution of Washington, Vol. 17: Alfred G. Mayor, Director; Shallow-Water Foraminifera of the Tortugas Region Collecting was done largely from the boats, the most satisfactory method that used with the Darwin. This is equipped with glass bottomed wells, and it was possible in collecting on the reef areas to let the snapper down to within a short distance of the bottom, where in the clear water it could be easily seen at several fathoms; then, on passing over a suitable spot, free from corals, the gear was allowed to run and samples of the bottom were obtained before coral heads again came in the way. Collecting in the moat at Fort Jefferson on Garden Key and in Shallow water on Long Key, as well as on the reefs and flats, was done by hand. An opportunity was afforded of studying living forms. Results of these studies are also given here, some of them being of special interest as throwing light upon disputed problems.
