英语翻译
A large branch of the current follows the E edge of the bank; this is the part which carries ice farthest S to reach the transatlantic shipping routes.Another branch rounds Cape Race and sets SW.Although some of the water that has passed on to the Grand Banks continues in a more S direction,especially during August to October,the bulk of it sets SW and continues,as a SW- going set,to fill the region between Newfoundland,Nova Scotia,and the Gulf Stream.
The Labrador Current subsequently continues S along the coast of the United States as a cold current as far as about 36°N from November to January,37° N from February to April,38°N from May to July,and 40° N from August to October.Between the S limit of the Labrador Current and the Tail of the Bank,the warm and cold waters converge on a line which is known as the 'Northern Edge' (or sometimes the North Wall) of the Gulf Stream.
The E end of the Northern Edge presents the greatest hydrographic contrasts to be found in the world,the water changing from the olive or bottle green of the Arctic side to the indigo blue of the Gulf Stream:a temperature change of 12℃to 0℃ has been recorded within a ship's length

洋流的一大支流沿（北美）东岸而下；这是将冰块带到最远的南面以到达跨大西洋航线的那部分洋流.另一支流沿着开普雷斯并流向西南.尽管部分水流已经越过纽芬兰大浅滩并继续向更南的方向流动,尤其是在8月至10月间,大量的水流还是向西南方向流去并继续沿着西南方向流去,填满纽芬兰、新斯科舍（加拿大东部省份名）和墨西哥湾洋流之间的区域.
拉布拉多洋流随后继续向南作为寒流沿着美国海岸南下,从11月到次年1月流经北纬36度海域,从2月至4月流经北纬37度海域,从5月到7月流经北纬38度海域,从8月到10月流经北纬40度海域.在拉布拉多寒流的最南端和大浅滩的尾部,温暖的海水和寒冷的海水在这里交汇,被称为墨西哥湾暖流的“北端”（或者有时称为北墙）.
北端最东端代表了迄今发现的世界上最强的水文对比,水由靠近北冰洋一端的橄榄绿或深绿色渐变为墨西哥湾的靛蓝色,从船舶记录来看,驶过一艘船厂的距离,温度由12度变为0度.
 
【解析】这是讲述大洋环流,即拉布拉多寒流和墨西哥湾暖流的交汇处的水温状况,附张图你瞧瞧,
