A basin-wide sea-level depression of approximately −60 cm hit the Baltic Sea in February 2026, driven by persistent high pressure and easterly winds that forced a massive outflow. Daily global mesoscale eddy tracks have now been calibrated for ocean intelligence, offering scientists a validated, real-time view of these powerful rotating currents from satellite altimetry.

Winter 2025/2026 Baltic Sea depression reveals atmospheric forcing on ocean volume
A basin-wide sea-level depression of approximately −60 cm hit the Baltic Sea in February 2026, driven by persistent high pressure and easterly winds that forced a massive outflow. The volume anomaly reached −290 km³ before recovering 76% of that loss by April. This is not merely an oceanographic curiosity; it is a measurable climate indicator.

Daily Global Eddy Tracks Now Calibrated for Ocean Intelligence
Daily global mesoscale eddy tracks have now been calibrated for ocean intelligence, offering scientists a validated, real-time view of these powerful rotating currents from satellite altimetry. This dataset transforms how we measure ocean energy transport and climate indicators. Understanding these eddies is essential, and for deeper context on ocean carbon fluxes, the ECCO‑Darwin model delivers first multi‑decadal global ocean CO₂ flux estimates. From orbit to ocean floor, we are building an integrated data ecosystem for a measurable, shared future.
