Fine-structure (centimeters to meters) in vertical profiles of acoustic volume scattering strength is a common and ecologically significant characteristic of the coastal marine water column. The processes that create these structures modify the avail

Within the coastal marine environment, populations of phytoplankton, zooplankton, bacteria, viruses, and aggregations of marine snow are frequently concentrated beneath the surface in discrete, vertically thin layers. Thin layers range in vertical di

Thin layers of plankton are recurrent features in a variety of coastal systems. These layers range in thickness from a few centimeters to a few meters. They can extend horizontally for kilometers and have been observed to persist for days. Densities

Measurements of bottom scattering strengths were made with a multi-frequency echo sounder mounted on a tower on a sandy bottom off West Destin, FL. Data were measured at five frequencies in the range 265–1850 kHz, at subcritical grazing angles rang

Huge accumulations of diatom-dominated marine snow (aggregates >0.5 mm in diam- eter) were observed in a layer approximately 50 cm thick persisting over a 24 h period in a shallow fjord in the San Juan Islands, Washington, USA. The layer was associat

Zooplankton biovolumes and sizes were determined from high-frequency acoustical measurements taken from an undulating SeaSoar vehicle on three cruises in the northern Arabian Sea. Cruises in 1994 and 1995 encompassed the periods of the winter Northea
