This dataset presents the number of germinated individuals that originated from protoplasts from Ulva lacinulata and Ulva compressa. The individuals are separated into different...

This dataset presents the diameter of the larger green cells found in the thalli of Ulva lacinulata and Ulva compressa that became protoplasts after being released to the water.

This dataset presents the fresh weight of U. lacinulata's biomass during the degradation experiment. This allowed the calculation of relative growth rates (RGR).

This dataset presents the number of protoplasts collected during the degradation experiment with Ulva lacinulata and Ulva compressa. This allowed the calculation of protoplast...

This dataset presents the diameter of the discs grown from protoplasts of Ulva lacinulata at the end of the germination experiment.

Snow temperature measurements were obtained doing classical snow pits during the ALERT2018 campaign in May 2018 over the sea ice in the Lincoln Sea. Snow pits were taken at...

Patterned ground of the polygonal tundra yields sensitive indicators of environmental and climate change. Polygon ponds, mires and cryosoils are typical components of Arctic...

We measured sea-ice thickness, snow depth, freeboard and sub-ice platelet-layer thickness by repeated drill-hole measurements between April 2013 and January 2014 at six stations...

Version 1, 2011-07-06. Please refer to the newest Version (see "Replaced by" reference).We continued our regular measurements of sea-ice thickness, snow depth and freeboard...

During the Polarstern cruise PS149 from July 2025 to August 2025 in the Atlantic part of the Arctic Ocean dielectric permittivity and dielectric loss of the snow and ice were...

During the Polarstern cruise PS149 from July 2025 to August 2025 in the Atlantic part of the Arctic snow and ice surface temperatures were measured using a waterproof...

During the Polarstern cruise PS149 from July 2025 to August 2025 in the Atlantic part of the Arctic Ocean, ice core samples were obtained with a 9 cm Kovacs corer during 30 ice...

Sea-ice salinity, temperature, density, thickness, and draft were measured during surveys at coring sites of the CONTRASTS expedition, with three to four sampling events...
