AMT17 Cruise Report

The main objectives of AMT17 were to acquire a consistent set of core measurements for comparison with data from earlier cruises, and to carry out new experimental work on planktonic processes relevant both to the AMT objectives and to future work at sea as part of a new marine biogeochemical projects. The latter included oxygen isotope measurements to assess the trophic balance within surface waters, measurements of the turnover rates of organic substrates by bacteria, and nutrient addition experiments to identify limiting substrates for phytoplankton growth.
