In Curve B, at Station 43, in theGulf Stream itself, all this warm water below 100 fathomshas disappeared; but a surface-stratum has been added,of a temperature rising to 24° C. Still further on, at Station44 (Curve C), a short distance beyond the western limits ofthe Gulf Stream, we find ourselves in the midst of an Arcticcurrent rising up to within 300 fathoms from the surface, with a o H z<-II- < X oeO z 00lU oe i; DCUl Ul. ^ ^ a a 2; ;zi < CQ o Z< I- < z«- CCO z COUifiC < UlQ.
