OCEANOGRAPHIC AND ACOUSTIC MEASUREMENTS IN DRAKE PASSAGE

On December 2001 the Argentinean Naval Service of Research and Development participated in the LMG01-9 expedition to Antarctic Peninsula, which was part of the Antarctic Program of the National Science Foundation of the USA for 2001. The inclusion of a SENID researcher, in the role of scientific nat...
