Seasonal Cruise Q3

The Nansen Legacy Q3 cruise, 5-27 August 2019, initiated the seasonal investigations of the Nansen Legacy transect. The transect represent an environmental gradient going through the northern Barents Sea, and included 7 process stations (P1-P7) lasting 6-53 hrs. CTD stations were taken to increase the hydrographic resolution on the transect. The program included measurements and sampling from the atmosphere, sea ice, ocean and sea floor. Data collected ranged from physical observations, chemical, biological and geological data collection, and the aim was to link observations and measurements to improve our understanding of the systems involving both climate, human impacts and the ecosystems. Deployment of moorings and gliders extended the observational capacity in time and space, outside the cruise period.

PC-2 Winter Process Cruise (WPC)

The Winter Process Cruise (WPC) aboard RV Kronprins Haakon (KH2021702) conducted observations on processes that control the position and variability of the polar front in the Northern Barents Sea and the distribution of Arctic and Atlantic water masses. Moreover, the WPC serviced 2 gateway moorings sites (M1 and M4) and collected complementary hydrographic, microstructure and current profiles to detect the winter circulation pattern and the layering structures between the two competing water masses. Meteorological measurements were also made.

Sampling Protocols

The collection of detailed sampling protocols is crucial tool for the success of the Nansen Legacy, because they ensure: Methodological agreement between the involved researchers Continuity and comparable data throughout the 5 years sampling period An easily accessible overview over parameters sampled Easier cruise planning

The Nansen Legacy

The scientific investigation of a rapidly changing northern environment leads to research questions of such intellectual, empirical and logistical complexity—and of such importance to the management of national resources and associated international obligations—that they can only be addressed properly through national and prioritized cooperation, with the highest scientific standards.

SS-MSC2 Process cruise/mooring service 2020

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.

Mooring service cruise 2019

The main objective of the joint Nansen Legacy and A-TWAIN/SIOS-InfraNor mooring service cruise was the recovery and deployment of the projects’ moorings in the Barents Sea and north of Svalbard. Additionally, CTD stations with water sampling for both projects, a Seaglider deployment for NL, and mooring recoveries and deployments for partner projects were planned, depending on sea ice conditions and time available.
