Wayne Camp posted in LinkedIN that real-time ocean and Great Lakes surface water measurements check out the data provided by the Viking explorer vessels https://lnkd.in/gWiYRiCV

Graph shows a number of parameters, such as surface water temperature measured recently by the Polaris vessel crossing the Antarctic convergence in the Southern Ocean into Antarctica from about 8 °C to -1 °C. These vessels also regularly release weather baloons to record data used for weather forecasting such as provided by https://www.windy.com.
The Viking Octantis and Vicking Polaris cruise ships carry automated oceanographic equipment (The FerryBox System) that measures marine conditions while underway at sea.
