HABITAT
VARCHAR
No
No
Active
Habitat assignment based on physical and biological features. | Description Source: Unknown
Biogenic sands: Biogenic sands had visible biological features such as mounds, pits, burrows, worms, tubes or oxic voids in sediments. | Depauperate sands: Depauperate sands had no visible evidence of biological features, which was likely related to their shallow (possibly intertidal) distribution in the bay. | Halodule bed: Seagrass habitats were divided into two mutually exclusive subclasses based on species composition, including Halodule wrightii and Valisneria americana. | Homogeneous silts: Silty-bottom habitats with no evidence of subsurface layering. | Layered silts: Silty-bottom habitats with visible sediment layering below the surface. | Oyster bed: Oyster beds predominantly consisted of oysters (Crassostrea virginica) and also included mixed beds of oysters and mussels. | Valisneria bed: Seagrass habitats were divided into two mutually exclusive subclasses based on species composition, including Halodule wrightii and Valisneria americana. |
