Leg1

Chief scientist David Barber:

Leg 1 of the 2018 Amundsen cruise was successful. Many of our objectives for the cruise and BaySys project were achieved, baring a few locations in the bay in which were not able to access due to ice and weather conditions. Overall, data collection and sampling went exceptionally well, including all onboard and remote-based (i.e., helicopter; zodiac; barge; and on-ice) operations (see Table 7.1).

Leg 2

The main goals of our team for LEG 2a of ArcticNet 2018 were to establish the horizontal and vertical distributions of nutrients, to measure the primary production and nitrogen uptake in the water column, and to assess the concentrations of fatty acids in phytoplankton as well as zooplankton. The auxiliary objective was to access the effects of acidification and temperature on lipids.
