  • Trace metal status in marine biological samples: a review

    The literature on trace metal status in marine biological samples is reviewed, taking into account the importance of the subject. Marine organisms accumulate trace metals to body concentrations well above those in seawater. Different marine organisms differ significantly in accumulated tissue and total body concentrations of heavy metals. The present literature survey indicates that more than 26 ...

  • Fish out of water — marine management in a changing climate

    A fisherman's tale: on the night of 6 October 1986 lobster fishermen from the small town of Gilleleje, north of Copenhagen, fishing the Kattegat Sea, found their nets crammed with Norway lobster. Many of the animals were dead or dying. About half were a strange colour. Observations of dissolved oxygen in the water in combination with the dead lobsters told researchers at the National ...

  • Panama Canal: Boat Towed 3D Resistivity Surveys - Case Study

    The Panama Canal Authority (ACP) needed to expand the canal in order to accommodate larger ships (and more traffic)—but first, they needed to know two things: what types of sediment loads needed to be dredged out—and more importantly—how much these loads would cost. That’s where AGI marine resistivity imaging ...

  • Marine specimen banking: archive and pollution control for the 21st century

    The oceans have in the past been extensively used as disposal sites for various kinds of waste. The world ocean – being the final sink for many natural and anthropogenic substances – is a "labile" ecosystem, which is and has for a long time been the focal point of extensive interdisciplinary research. Measurements of heavy metals and a suite of various chemical compounds in the marine ...

  • Evaluation of the impact of industrial sewage pollution on marine benthic communities

    A survey was performed to assess organic pollution, water properties and the marine benthic community. The need to assess the environmental status of marine and coastal waters encouraged the design of specific biotic indices to evaluate the response of benthic communities to human-induced changes in water quality. In this study of the benthic community structure in Ghanam Creek surrounding an ...

  • Top 5 ways marine researchers are currently using Underwater Drones

    Marine researchers around the world are utilizing Deep Trekker Underwater Drones (or ROVs) in their marine projects; here are the top 5 applications being used today. In a few weeks, the world will gather in San Diego, California for the Oceanology International North America exhibition. It will bring together ...

  • Marine pollution in Australia, with special emphasis on central New South Wales estuaries and adjacent continental margin

    This paper reviews the current knowledge and environmental status of Australian estuaries and continental margins in terms of sedimentary heavy metals. Although only 2.5% of Australian estuaries and 0.1% of the adjacent continental shelf have been surveyed for sedimentary heavy metals, some of the most contaminated maritime areas in the world have been located in this country. The most ...

  • Survey on Existing Sample Archives For The Assessment of Time Trends of Pollutants in The Environment of New EU Member States and Candidate Countries

    Foreword Potentially high levels of chemical pollution in the EU+10 compared to the EU 15 Member States generate concern on the environmental status of the former. Especially contaminations in the agro-environment of the new EU MS may result in an increase of the overall human exposure in the enlarged EU. First attempts to collect concrete data on polychlorinated dioxins (PCDDs), -furans ...


  • Effects‐based marine ecological risk assessment at a polychlorinated biphenyl‐contaminated site in Saglek, Labrador, Canada

    Although the presence and distribution of polychlorinated biphenyls (PCBs) in Arctic marine environments has been well documented, the implications for the health of biota are poorly understood. In the present study, multiple lines of evidence, including site‐specific effects data, were used to assess PCB‐related risks to marine biota at a contaminated military site in Saglek Bay, Labrador, ...

  • Las Flores basin hydrogeology, camp Pendleton marine corps base, San Diego County, California.

    The Las Flores basin is located in northwest San Diego County, California, on the Camp Pendleton Marine Corps base. The Las Flores basin is one of four groundwater basins that supply drinking water to Camp Pendleton. Groundwater in the Las Flores basin is extracted from the alluvial aquifer and the San Mateo aquifer located in the coastal basin. The San Mateo aquifer is overlain by unconsolidated ...

  • Molecular screening of microbial communities for candidate indicators of multiple metal impacts in marine sediments from Northern Australia

    Coastal sediments accumulate metals from anthropogenic sources and as a consequence industry is required to monitor sediment health. The total concentration of a metal does not necessarily reflect its potential toxicity or biological impact, so biological assessment tools are useful for monitoring. Rapid Biological Assessment (RBA) tools sensitive enough to detect relatively small increases in ...

  • Mapping top of rock and sediment thickness case study

    San Felipe, Panama A port expansion was planned off the coast of San Felipe, Panama. GeoView was tasked to provide bathymetric information within the survey area, map the top of rock and evaluate the thickness of the overlying marine sediments. The survey area was approximately 300 hectares in size. GeoView collected sub-bottom profiling and bathymetry data along transect lines spaced ...

  • Compare active and passive cables

    Active cables refer to the cable with electronic part in the cable. Control and ADC in resistivity system controls the electronic parts in the cable, which controls the current injection. Passive cables refer to the cable with no electronic part in the cable. One of the advantage of passive cables is its ability to borehole and marine surveys, operator can put passive cables in water. Putting ...

  • Fugro acquires consultancy to boost renewables business

    Fugro Renewables (Wallingford, U.K.) announced that it has acquired ERT, an Edinburgh-based environmental consulting firm, to complement its suite of services provided to developers of offshore wind, wave, and tidal power projects. “From feasibility studies and initial assessments to site surveys and investigations, construction services, and ultimately, decommissioning, Fugro ...

  • Mapping sediment thickness case study

    Polk County, Florida Bathymetric and sub-bottom surveys were conducted within a clay settling pond at a Phosphate mine in Central Florida. Prior to the geophysical survey, a depression or slump had formed along the northern dam of the pond. The purpose of the study was to map various sediment layers within the pond to help determine if the depressions or slumps were related to sinkhole ...

  • Biodiversity Detectives Solve Mysteries with Environmental DNA

    For years, Monterey Bay Aquarium’s 1.2 million gallon main tank has been a source of thrill for visitors seeking fish-eye views of life in the pounding Pacific Ocean right outside its doors. Now, thanks to advances in DNA sequencing, it’s also becoming a model for how to survey life inthat vast ocean with just a few glasses of water. In a study published last January in ...

  • Attitudes of Europeans towards the issue of biodiversity

    The European Union (EU) is committed to the protection of 'biological diversity', i.e. the variability among living organisms from all sources including, inter alia, terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems1. The EU has been legislating on biodiversity since the ...
