Der Einfluss von Seamounts auf die klein- und mesoskalige Verteilung des Phytoplanktons im zentralen, subtropischen Nordostatlantik
Ampere (35°05'N 012°55'W) and Great Meteor (30°00‘N 028°30‘W) Seamounts (subtropical NE-Atlantic) were visited in April 1996 and September 1998, respectively, to investigate the influence of these two seamounts on the distribution of phytoplankton. Measurements of the oceanographic conditi...
