Ocean Data Access and Tools

NASA data span the geophysical parameters that characterize the global ocean and the physical processes operating within its depths and at its surface. Our datasets and tools help researchers translate these interconnected data points into actionable knowledge.

Surface Water and Ocean Topography (SWOT) Platform

SWOT provides detailed surface topography and monitors water body changes over time. The platform enables high-resolution ocean monitoring at 15-150 km spatial scales, tracking ocean currents, coastal dynamics, storm surges, and regional sea level changes. On land, SWOT measures water storage changes in lakes, reservoirs, rivers, and wetlands, supporting river discharge estimates for water resource assessment.
