Sea ice lead fractions from multiple sensors in the Transpolar Drift during M...

Divergent sea ice motion breaks the ice and opens fractures and leads. Depending on the air temperature, those open-water areas can quickly refreeze. The open water or thin ice...

Flow cytometry dataset from first year sea ice (FYI) core bottom 5 cm section...

This dataset is a subset of the abundance of microorganisms (smaller than 20 µm) enumerated using flow cytometry (FCM) during the Multidisciplinary drifting observatory for the...

Flow cytometry dataset from CTD casts showing the abundance of microorganisms...

This dataset gives an overview of the abundance of microorganisms (smaller than 20 µm) enumerated using flow cytometry (FCM) during the Multidisciplinary drifting observatory...

Binary sea ice lead maps derived from Sentinel-1 SAR images during MOSAiC exp...

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...

Helicopter-borne RGB orthomosaics and photogrammetric Digital Elevation Model...

The Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition took place between October 2019 and September 2020 giving the rare opportunity to...

Spectral solar radiation over and under sea ice during the MOSAiC expedition ...

Solar radiation over and under drifting sea ice was measured using RAMSES hyper-spectral radiometers (TriOS) mounted on the remotely operated vehicle (ROV) during the...

Lead classification maps from helicopter-borne surface temperatures during th...

Leads (open water and thin ice) were classified in helicopter-borne thermal infrared observations. Lead classification maps, gridded in 1 m resolution, are provided for 35...

Helicopter-borne thermal infrared sea ice surface temperatures during the MOS...

We provide high-resolution surface temperature data for a better understanding of the spatial and temporal variability of sea ice surface characteristics in the Arctic winter....

Positioning and telemetry from ROV survey PS122/3_38-91 on 2020-05-02, survey 1

The horizontal position of the remotely operated vehicle (ROV) during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition between...

Composition of chromophoric dissolved organic matter in Central Arctic surfac...

The data set comprised the dissolved organic carbon (DOC), total dissolved nitrogen (TDN), DOC/TDN and the specific ultraviolet absorbance (SUVA254) for MOSAiC expedition, and...

Pollution mask for the continuous corrected particle number concentration dat...

This dataset contains a pollution flag in 1 min time resolution. It is derived by the pollution detection algorithm (PDA) based on the corrected particle number concentration...

Master track of POLARSTERN cruise PS122/3 in 1 sec resolution (zipped, 52 MB)

Raw data acquired by position sensors on board RV Polarstern during expedition PS122_3 was processed to receive a validated master track which can be used as reference of...
