About The Product

Published through the yankee Geophysical Union as a part of the Antarctic examine Series.

The distribution of Siphonophora of the Antarctic, Subantarctic, and adjoining areas of the Pacific and Atlantic Oceans is defined. Specimens for this research have been received through the usa Antarctic learn software from USNS Eltanin cruises 3-5, 8-23, 25-28, 35, and 38 in the course of spring, summer season, fall, and iciness. Samples have been accrued from 1962 to 1969, utilizing open-closing and nonclosing plankton nets. info is compiled on horizontal distributions of siphonophores within the South Atlantic Ocean west of 0°. Illustrations of the species, and maps of distribution on the 3 bathymetric degrees, also are integrated. furthermore, information on Eltanin cruise 30 are offered, overlaying mostly the Pacific tropical sector in the course of the summer time, with a few stations lower than the equator (austral winter). Vertical distributions of every species are mentioned for the 3 bathymetric zones: epipelagic (200-0 m), mesopelagic (1000-200 m), and bathypelagic (below a thousand m). lifestyles phases and differences due to the season also are thought of. 80 species of Siphonophora have been pointed out in those collections. between those, and defined somewhere else, have been 5 new species: Lensia eltanin, L. eugenioi, L. landrumae, Heteropyramis alcala, and Thalassophyes ferrarii. The eudoxid phases of L. lelouveteau and L. reticulata have been additionally stumbled on. moreover, the next infrequent Siphonophora species have been accumulated: Halistemma cupulifera, Desmophyes annectens, Lilyopsis rosea, Eudoxia macra, Lensia achilles, L. baryi, L. exeter, L. grimaldii, L. hostile, Nectocarmen antonioi, and Clausophyes galeata. the most typical species of the Antarctic?]Subantarctic quarter through the 4 seasons used to be Dimophyes arctica. The eudoxid levels of Chelophyes appendiculata, Diphyes dispar, Diphyopsis mitra, Clausophyes ovata, and Heteropyramis maculata have been plentiful.
