Ultramarine carries one of the few European Common Automatic Weather Stations operating on an expedition vessel today. Installed on the upper deck, it collects hourly data on temperature, pressure, humidity, wind, and vessel position—helping fill critical gaps in climate and forecasting models across the Polar Regions. STRENGTHENING GLOBAL FORECASTING THROUGH WEATHER DATA
Guests can also contribute manual observations of sea ice, wave height, and atmospheric conditions, adding context while engaging directly with onboard science. In 2025, the station shared over 8,500 observations with the German Weather Service and the World Meteorological Organization. This open-source data supports forecast centers worldwide and powers apps like Windy.
