[38] Krümmel (paper cited in footnote 26) suggests applying the name Sargasso Sea to the area limited by the curve of 5 per cent probability of occurrence on his map (our Fig. 1). This area amounts to 4,500,000 square kilometers, or somewhat less than half the area of Europe. Schott (see footnote 26), p. 140, gives 8,635,000 square kilometers as the area of his natural region Sargasso Sea, which is based not only on the occurrence of gulfweed but also on the prevailing absence of currents and on the relatively high temperature of the water in all depths.--EDIT.
