The HUDSON-70 expidition

HUDSON-70 was a multidisciplinary oceanographic cruise encircling North and South America. The aim of the expedition was to make a significant contribution to the exploration of the world´s oceans at the beginning of the International Decade of Ocean Exploration. The program included the total spectrum of oceanographic studies of interest to scientists today covering the fields of the life sciences, physics of the oceans and the earth sciences. Probably one of the main achievements for oceanographic studies was the opportunity to use identical measuring equipment in the two major oceans of the world - the Atlantic and Pacific, and at the same time obtain data in areas where little, if any, information was previously available particularly in the Arctic and Antarctic regions. This paper will review some of the more important scientific results of the cruise.
