The United States Geological Survey estimates that Virginia's barrier islands could be broken up by new inlets or lost to erosion if sea level rises two feet by the year 2100. Beach erosion will threaten the oceanfront portion of Virginia Beach, unless people take measures to offset the erosion. Rising sea level also threatens bay beaches and ...
The natural environment of Virginia encompasses the physical geography and biology of the U.S. state of Virginia. Virginia has a total area of 42,774.2 square miles (110,784.67 km 2 ), including 3,180.13 square miles (8,236.5 km 2 ) of water, making it the 35th- largest state by area. [ 1 ]
Drivers, processes, and impacts of sinking cities [1]. Sinking cities are urban environments that are in danger of disappearing due to their rapidly changing landscapes.The largest contributors to these cities becoming unlivable are the combined effects of climate change (manifested through sea level rise, intensifying storms, and storm surge), land subsidence, and accelerated urbanization.

The map below shows changes in the aragonite saturation level of ocean surface waters between 1880 and 2012. [107] To pick one example, pteropods are a group of widely distributed swimming sea snails. For pteropods to create shells they require aragonite which is produced through carbonate ions and dissolved calcium. Pteropods are severely ...
CLIMAP map of ice sheets, sea temperature changes, and changes in the outline of coastal regions during the last glacial. Climate: Long range Investigation, Mapping, and Prediction , known as CLIMAP , was a major research project of the 1970s and 80s to produce a map of climate conditions during the Last Glacial Maximum .
A bathymetric chart is a type of isarithmic map that depicts the submerged bathymetry and physiographic features of ocean and sea bottoms. [1] Their primary purpose is to provide detailed depth contours of ocean topography as well as provide the size, shape and distribution of underwater features.
Virginia Wildlife Management Area boundary sign. WMAs in Virginia differ from other state-managed protected areas in that they are solely intended to preserve and improve wildlife habitat, with a particular focus on game animals, and to provide public space for hunting and fishing activities.
Coastal ocean dynamics. Coastal ocean dynamics are important for many societal applications. They have smaller spatial and temporal scales than the dynamics of the open ocean and require finer-scale monitoring. SWOT will provide global, high-resolution observations in coastal regions for observing coastal currents and storm surges.
