Respiratory electron transport activity in plankton of the Weddell and Scotia Seas during late spring - early summer: relationships with other biological parameters
8 pages, 5 figures, 3 tables As a means to estimate potential oxygen consumption, profiles of elctron transport system (ETS) activity were made along three transects across the Weddell-Scotia Confluence zone (WSC) and the marginal ice zone (which overlapped in part) during the EPOS leg 2 cruise of t...
