New equipment for benthic habitat studies
Oceans '97. MTS/IEEE Conference Proceedings, 2002This paper presents an overview of new systems used in benthic habitat studies at the Bedford Institute of Oceanography. These new systems include towed, profiling and moored instruments. A partial list of sensors used in these systems includes high resolution video, silhouette cameras, hydraulic bottom grab, surficial floc sampler, water bottles and a

Abstract Polar land habitats suffer extreme variation of conditions, with desiccation or mechanical damage by wind, unstable substrates, or ice movement, as the usual limiting factors. Shallow inland waters have similar disadvantages. Deeper inland waters afford more stable conditions with steady temperatures and ample water, but tend to

GIS-based mapping of benthic habitats
Estuarine, Coastal and Shelf Science, 2003The aim of the work was to map and analyse benthic habitats in the Polish zone of the Baltic Sea using the Geographical Information Systems (GIS). The habitats definitions were analogous to those proposed in the HELCOM classification, which is based on two concepts—the euphotic zone has no clearly defined boundaries and the bottom sediments are defined

Benthic Habitats and the Effects of Fishing
2005<strong><em>Abstract. </em></strong>This paper first considers why it has been so difficult to make progress on moving fisheries toward ecological sustainability even in the narrow context of the target species. It then reviews the additional challenges that must be confronted when addressing the ecosystem effects of fishing ...

Benthic foraminifera in oxygen-poor habitats
Marine Micropaleontology, 1993Abstract Numerous eurytolerant species of calcareous and agglutinated benthic foraminifera, belonging to diverse suprageneric taxa, survive under modern dysoxia and su☐ia (2-0 ml/l O2), as well as under higher oxygen levels. Under the usual combination of oxygen depletion and organic-matter enrichment of the substrate, the populations of some of ...

A review of approaches for classifying benthic habitats and evaluating habitat quality
Journal of Environmental Management, 2004We have assessed the current state of knowledge relative to methods used in assessing sub-tidal benthic habitat quality and the classification of benthic habitats. While our main focus is on marine habitat, we extensively draw on knowledge gained in freshwater systems where benthic assessment procedures are at an advanced stage of maturity.

Benthic Habitats of the Florida Keys
1998This atlas contains 32 color maps depicting the benthic habitats at a scale of 1:51,500. In addition to showing the locations and extents of different habitat types in the Florida Keys, the atlas provides a brief description of the Florida Keys region, summary information on the extents of the ecological habitats by subregion, and a detailed ...

Isoprene emissions from coastal benthic habitats
2020Isoprene is a climatically important biogenic volatile organic compound with oxidation in the atmosphere leading to ozone and aerosol production. While predominantly terrestrial, isoprene can be sourced from the ocean, although this needs to be quantified.
