The YOPP International Project (2013–2022) Year Of Polar Prediction
The YOPP Project is initiated by the World Meteorological Organization to develop improved weather and environmental forecasts in the polar regions on time scales from hourly to seasonal variability.
The iceSVP-B/40H sea drift buoys designed by Marlin-Yug LLC (https://marlin-yug.com/assets/files/pdf_ru/drifter_svp_30h_40h_ru.pdf) adapted for use in polar regions are used in the works.
The first two buoys were installed on the ice in April 2018 near the North Pole. When ice melts, the underwater sail automatically deploys and the buoy continues to work as a marine drifter. The project is supposed to use more than 60 of such devices.
Data are transmitted via the Iridium system, and buoys position data are transmitted via the GPS/GLONASS systems.
Buoys measure the motion parameters of ice (water), air (water) temperature and atmospheric pressure when on ice or in water.
