Animations, graphs and data from the USGS Open File Report 2013-1081 and the USGS project "Modeling Sea-Level Rise in San Francisco Bay Estuary" can be found online.

This photo shows a USGS researcher surveying marsh topography using a RTK GPS measuring unit, collecting data that was used to build the sea level rise forecasts for this USGS Open File Report.

An aerial view of subsiding marshes in the Mississippi River Delta. This region contains vast areas of marshes, swamps, and barrier islands—important habitat for wildlife, as nursery grounds for marine life, and as protective buffers against storms and hurricanes. However, rapid land subsidence due to sediment compaction and dewatering increases the rate of submergence in this deltaic system.
