description:
|
This map provides an overview of the loose sediment types in the Gulf and is a guide to their mobility under waves and currents, as well as to the physical factors for benthic animals. Sediment can be classified in a variety of ways.
One method, known as the Folk Codes (Folk, 1974) divides sediments into mud, gravel and sand, depending on how big the particles are. Sand, coarse mud (silt), and fluid muds are unstable in areas affected by waves and currents. Gravel and stiff mud are unstable only in extreme weather conditions. Muddy bottom areas on slopes of 2° or more are prone to sliding and mass failure caused by gravity and internal sediment pore-water pressures.
The data for this analysis comes from a subset of USGS's usSEABED called dbSEABED. |
