Biological assessments utilize information from biological communities, along with measures of physical and habitat characteristics, to provide data for water quality management purposes, including the identification of contaminant sources, causes and severity of impairments, evaluation of the effectiveness of control measures and restoration activities, use attainability studies, and trend ...
by:Aqua Survey, Inc. based inFlemington, NEW JERSEY (USA)
Aqua Survey has a wide variety of sampling equipment such as: benthic grab samplers, kick-nets, gill-nets, seines, bongo-nets, plankton-nets, epibenthic sleds, fish traps, trawls, underwater video camera, underwater digital still cameras, lightweight ROVs and other monitoring equipment. Specimen samples are collected, sorted, taxonomically identified and enumerated by ASI ...
by:EOMAP GMBH & CO. KG based inSeefeld, GERMANY
EOMAP can map, classify, and quantify the seafloor in shallow waters. Our benthic cover and habitat mapping methods are based on our value-added processing chain, which removes the distorting effects of the atmosphere, water surface, and water column from the satellite imagery. This offers you an unbiased and focused view of the seafloor over vast areas, contrary to spotty ...
by:Aqua Survey, Inc. based inFlemington, NEW JERSEY (USA)
To support benthic investigations Aqua Survey can deploy a Smith-Macintyre grab sampler to collect sediment and benthic macroinvertebrate samples. Once the macroinveretebrate samples are onboard the samples can be prepared with a sieving station to process the samples making them ready for the laboratory to sort and identify. ...
by:Timberline Aquatics, Inc. based inFort Collins, COLORADO (USA)
At Timberline Aquatics, Inc. we take pride in our working knowledge of indices (metrics) that use benthic macroinvertebrate data to describe aquatic conditions. These metrics include those described in the EPA’s Rapid Bioassessment Protocols and numerous others that are designed to detect a variety of specific disturbances. Timberline Aquatics, Inc. has an extensive library ...
by:Green Rebel based inCork City, IRELAND
Our expert team take into consideration a number of key parameters, including proximity to Special Protected Areas (SPAs) or Special Areas of Conservation (SACs), bathymetry and benthic habitat. This strategic design maximises the accuracy of the survey data and ensures adequate precision for detecting changes ...
by:Apercu Consultants, Inc. based inQuezon City, PHILIPPINES
Based on images from the video, software applications can be used to evaluate fish populations, coral diversity, percent benthic cover of corals, algae, and other organisms. Considering time and other constraints while scuba diving, underwater video monitoring allows sampling of larger areas of the reef in less time as identification and analysis are done on land. ...

Fish, benthic invertebrate, and vegetation chemistry studies. Fish health assessments. Fish ...
by:Partrac Ltd based inGlasgow, UNITED KINGDOM
Collection of seabed samples is often required for seabed geological mapping to ground-truth geophysical investigations, for validation of sediment transport models and to delineate benthic habitats for environmental impact ...
by:Nautilus Environmental based inBurnaby, BRITISH COLUMBIA (CANADA)
Adding physical and biological metrics to chemical and toxicological assessments provides a more comprehensive evaluation of the condition of a given body of water, and provides a means with which to quantitatively separate impacts of non-chemical substances, such as sedimentation and habitat degradation, from the effects of chemical contaminants and changes in the hydrological regime. While ...
by:Aqua Survey, Inc. based inFlemington, NEW JERSEY (USA)
ASI’s EM systems are high powered to maximize their detection range. EM systems can be towed behind
survey vessels on floating platforms or submerged
benthic sleds, to survey up to 6-meter swaths, towed
by a diver (1-meter swath) or included within the
nosecone of a vibracoring barrel (4-inch ...

by:Marine Research Ltd. based inBucharest, ROMANIA
Acoustic Seafloor Classification using Side-scan sonar data. Mapping benthic habitats is necessary for the implementation of a balanced approach on ecosystems in the management of marine protected areas. It is focused on monitoring and identifying the marine ecosystems by shaping the geometry and distribution of the habitats and building up a complete map of the seafloor. ...
by:Alpha Analytical Laboratories based inWestborough, MASSACHUSETTS (USA)
Total PAH concentrations in sediment are generally recognized in the literature to be poor predictors of benthic invertebrate toxicity. Pore water analysis provides a better indication; however, the direct measurement of PAH concentrations in pore water has traditionally been very ...
by:Pacific EcoRisk based inFairfield, CALIFORNIA (USA)
Sediments and their associated benthic organisms are critically important in maintaining the overall health and productivity of aquatic ecosystems. For a number of reasons, sediments are often the primary sink for contaminants. As a result, sediments can be the most sensitive and ecologically important component of aquatic systems, and assessment of sediment toxicity and ...
by:ASI Group Ltd. based inHamilton, ONTARIO (CANADA)
EEM is not just an end-of-pipe measurement of the concentrations of various contaminants in effluent. Monitoring of the fish populations and benthic invertebrate community is done in local aquatic environments, to determine if the effluent is having any effects on fish, fish habitat and the human use of fisheries resources.ASI’s full accredited in-house laboratory enables ...
