Atmospheric profiles of temperature, humidity, wind speed and direction from radiosondes (Vaisala RS92-SGPL) released from ship, R/V Lance. A total of 27 radiosonde launches were conducted during the Fram Strait 2017 cruise from August 25th to 10th September 2017. Sondes were launched one or two times a day around 00 UTC and 12 UTC.

CTD profiles from multiple transects over the continental slope north of Svalbard in September 2012

CTD profiles from multiple transects over the continental slope north of Svalbard in September 2012

Samples for Uranium 236 and I 129. Collected on ship CTD during cast 42 and 44 in June between 5m and 400m depth.

Ocean microstructure profile from a lead during leg 2 (floe 2) with VMP250 microstructure profiler

Sensible & latent heat fluxes, momentum flux, roughness length, boundary layer height, and CO2 flux from intermittent deployments of eddy-covariance system by KOPRI scientists.

Temperature, Humidity, wind speed and direction (radiosondes), boundary layer height

Laser leveling exercises with rotating laser were carried out during N-ICE 2015. The sea-ice and snow surface elevation were computed with reference to the local sea-surface found by drilling at the corners of the laser leveling field.

Bromoform (CHBr3) fluxes from sea ice measured with chamber technique

Sea ice, snow depth, freeboard, and total thickness (ice + snow) measurements from 2" drillholes or ice core holes during the N-ICE2015 expedition. EM31 conductivity value for EM31 calibration are included where available.
