The towering trees in Gabon's impenetrable mangrove swamps have helped to make the Central African country one of the world's few net absorbers of carbon as the plants sequester the greenhouse gas four times faster than forests on land.

The shallow waters around islands and continental coastlines are important for human activities and for the health of many marine species. However, these areas are constantly evolving and notoriously challenging and time-intensive to map. For several years, remote sensing scientists have worked to change that paradigm. A recent study led by NASA-funded researchers shows how it might be done with freely available satellite data and cloud computing.
For centuries, marine surveyors relied on shipborne tools – first sounding lines, then sonar – to decipher the depth and shape of the seafloor, or bathymetry. Starting with U.S. Landsat satellites in the 1970s and more recently with European Sentinel satellites, researchers have been slowly developing ways to derive bathymetric information from satellite images.
