    Abstract

    The cruise KB 2018616 aboard the Research Vessel Kristine Bonnevie is the first research cruise of the project the Nansen LEGACY. LEGACY is the Norwegian Arctic research community’s joint effort to establish a holistic understanding of a changing marine Arctic climate and ecosystem. KB 2018616 is a physical oceanography cruise with objectives to conduct ocean mixing and water transformation process studies in the region west and north of Svalbard, with particular focus on the warm Atlantic boundary current. Ocean stratification, current and microstructure measurements were made. Four main sections were taken across the path of the warm West Spitsbergen Current; a fifth section was incomplete, interrupted by the ice edge extending to shelf at 24E. Profiles were collected at stations along the sections from shelf to deep water as well as at two repeat stations, each for approximately 24 hours duration. Profiles covered the full water column, except the shipboard acoustic Doppler current profiler (SADCP) sampled the upper 300-400 m. The cruise was completed with a section into Isfjorden. In total 120 CTD (conductivity temperature depth), 106 LADCP (lowered acoustic Doppler current profiler), 200 microstructure profiles and 11.5 days of SADCP data were collected.

    Abstract

    The cruise GOS 2020113 (6 October 2020 Longyearbyen, 27 October 2020 Tromsø) aboard the Research Vessel G.O. SARS is a mooring service/deployment and process studies cruise of the Nansen LEGACY project. The study region covered 24-35E and 75-79N, with objectives to deploy moorings for process studies (1 year duration), service and redeploy accessible gateway moorings (long term), deploy underwater gliders (cruise duration as well as 3-4 months missions), conduct ocean mixing and water transformation process studies in the Barents Sea Polar Front region east of Svalbard, and sample for biology, nutrients and the carbonate chemistry in the water column at selected stations. The cruise contributes to tasks T1-1 on the Atlantic Water inflow to the northern Barents Sea at key gateways, T1-2 on processes that control sea ice and stratification in the northern Barents Sea, T2-1 on ocean acidification, T3-2 on timing of critical biological processes. Overall, we deployed 7 process moorings with physical oceanography focus, recovered and redeployed gateway moorings M3, M5 and M5-bioac and recovered the gateway mooring M6. We collected measurements of ocean stratification, currents, and microstructure from the vessel as well as from transects using ocean gliders. From the vessel we obtained 212 microstructure profiles down to 0-20 m above seabed; 64 CTD (32 with bottle sampling) and 63 LADCP profiles down to 5 m above seabed, and 20 days of underway current profiles. From gliders we obtained 801 profiles (16 days) including 266 profiles (6 days) using microstructure sensors in the polar front region north of Hopen Trench, and 678 profiles (10days) between the Great Bank and the Central Bank. Using the CTD’s water sampler, we collected 149 water samples for nutrient and carbonate chemistry analyses, 136 for POC/PON analyses, 68 for dissolved oxygen analyses, 52 for chlorophyll analyses, and 48 for phytoplankton analyses. We used multinet and bongo net for mesozooplankton sampling. We performed 4 hauls with Multinet (2 with 64 µm and 2 with 180 µm meshed net) and 29 hauls Bongo net (18 profiles with the 180 µm and 40 profiles with the 64 µm meshed net).

    Abstract

    The cruise GOS 2020113 (6 October 2020 Longyearbyen, 27 October 2020 Tromsø) aboard the Research Vessel G.O. SARS is a mooring service/deployment and process studies cruise of the Nansen LEGACY project. The study region covered 24-35E and 75-79N, with objectives to deploy moorings for process studies (1 year duration), service and redeploy accessible gateway moorings (long term), deploy underwater gliders (cruise duration as well as 3-4 months missions), conduct ocean mixing and water transformation process studies in the Barents Sea Polar Front region east of Svalbard, and sample for biology, nutrients and the carbonate chemistry in the water column at selected stations. The cruise contributes to tasks T1-1 on the Atlantic Water inflow to the northern Barents Sea at key gateways, T1-2 on processes that control sea ice and stratification in the northern Barents Sea, T2-1 on ocean acidification, T3-2 on timing of critical biological processes. Overall, we deployed 7 process moorings with physical oceanography focus, recovered and redeployed gateway moorings M3, M5 and M5-bioac and recovered the gateway mooring M6. We collected measurements of ocean stratification, currents, and microstructure from the vessel as well as from transects using ocean gliders. From the vessel we obtained 212 microstructure profiles down to 0-20 m above seabed; 64 CTD (32 with bottle sampling) and 63 LADCP profiles down to 5 m above seabed, and 20 days of underway current profiles. From gliders we obtained 801 profiles (16 days) including 266 profiles (6 days) using microstructure sensors in the polar front region north of Hopen Trench, and 678 profiles (10days) between the Great Bank and the Central Bank. Using the CTD’s water sampler, we collected 149 water samples for nutrient and carbonate chemistry analyses, 136 for POC/PON analyses, 68 for dissolved oxygen analyses, 52 for chlorophyll analyses, and 48 for phytoplankton analyses. We used multinet and bongo net for mesozooplankton sampling. We performed 4 hauls with Multinet (2 with 64 µm and 2 with 180 µm meshed net) and 29 hauls Bongo net (18 profiles with the 180 µm and 40 profiles with the 64 µm meshed net).
