Concentrations of Chlorophyll a from special sampling events during the MOSAiC (PS122) drift expedition in the central Arctic Ocean. 0.3-4L of water were filtered onto...

Nutrient concentrations (NO3−, NO2−, NH4+, PO43−, and Si(OH)4), water oxygen isotope compositions (δ18O), and salinity were measured for ice samples from melt pond, and water...

Algal pigment concentrations were retrieved from meltponds and leads, during Leg 4 and 5 of the MOSAiC expedition (Multidisciplinary drifting Observatory for the Study of Arctic...

During winter, a significant part of the Arctic Ocean is covered with sea ice. Sea ice works as an insulation layer between the ocean and the atmosphere. The presence of leads...

Leads and pressure ridges are dominant features of the Arctic sea ice cover. Not only do they affect heat loss and surface drag, but also provide insight into the underlying...

The data show the long-term relative sea ice lead frequencies for the Arctic (November – April 2002/03 – 2018/19) and Antarctic (April – September 2003 – 2019), respectively....

The dataset comprises stable water isotopes and conductitities of a lead case study during leg 5 of the MOSAiC campaign. Samples have been taken from different water and ice...
