Abstract
Observational data for this discussion were obtained principally during the two
cruises of the oceanographic research ship, "Atlantis," to the Caribbean Sea March 7 to May 5, 1933 (stations 1487-1610) and February 2 to March 2, 1934 (stations
1935-2002). The oxygen determinations, carried out on board, have been published in
Bulletin Hydrographique (1934, 1935) together with other hydrographic data.
The Caribbean Sea region falls into two natural bathymetric subdivisions: a
western, lying between Yucatan Channel and a ridge extending from Honduras to Haiti
via Jamaica, designated in this paper as the "Cayman basin," and an eastern, between
this ridge and the lesser Antilles, here designated as the "Caribbean basin".
"Cayman basin" has been used by Parr (1937) and by Rakestraw and Smith (1937), and,
while antedated by "Yucatan basin" (Krümmel, 1907) it seems that less confusion will
arise if the term "Cayman" is used in this discussion.
The "Atlantis" observations supply for the first time the necessary information for
a detailed study of the distribution of oxygen in the Caribbean Sea region. The 1933
and 1934 observations are here used indifferently; such a procedure seemed desirable
since the data are insuffcient for determination of annual or seasonal variations, particularly
in view of the disturbing effect which may be caused by short period vertical
oscillations of relatively large magnitude.
