Arctic and Antarctic buoy data are available in near real time on http://data.seaiceportal.de. These buoys also contribute to the in-ternational buoy networks, as well as to the Global Telecommuni-cation System (GTS). The data of all buoys are pu-blished and distributed through the online data-base PANGAEA.

One central node and 3 sub-nodes represent one drifting observatory. Each year between 2017 and 2020, two such observatories will be de-ployed upstream the Transpolar Drift of the Arctic Ocean.

The remotely operated vehicle „BEAST“ is equipped with similar sensors as the buoys, and used to characterize the spatial variability of key parameters

on floe scale.

Region of planned deployments

Central Arctic & Weddell Sea buoy deployments between 2013 and 2016, and region of planned de-

ployments in 2017.

to overcome the Three main observational challenges in ice-covered oceans:Spatial coverage:

the challenge of scalesTemporal coverage:

the challenge of seasonalityInterdisciplinarity:

climate- & ecosystem interaction

Outlook: ROV operations & buoy observatories are critical elements of the MOSAiC experiment in 2019/20.
