Distinct from the benthic (seabed) habitat.Ī method of detecting discontinuities in the water, often used for current and turbidity measurements and for detecting changes in the character of the seafloor.Ī process by which species evolve, and by which individuals adapt, their growth and/or behaviour to better survive and grow in a particular environment.

The glossary could be expanded should experts offer to do so and where no existing online peer-reviewed glossary exists. ![]() At present, this glossary excludes terminology specific to the following areas: names of marine species and higher taxa (see WoRMS) place names (see gazetteers at Marine and GEBCO) taxonomy physiology archaeology fisheries legal and regulatory terms acronyms. Where a term has different uses that the editors feel require clarification, then these will be included. The definitions are those recommended for use in marine biology, ecology and geology. As it was removed after a few years with the intention of being replaced by an improved system it is here republished. The glossary does not intend to provide a review or history of all uses of particular terms, nor how they may be used in other fields of research. It was published online on WoRMS from 2010 and comments by users led to additions and corrections. This glossary was developed as a collaboration between the scientists of the GEOHAB ( Marine Geological and Biological Habitat Mapping) and WoRMS ( World Register of Marine Species) communities. ![]()
