TL;DR: The Mt Mitchell as discussed by the authors operated in the Gulf, Strait of Hormuz, and Gulf of Oman from February to June 1992, with seven separate legs, six official legs and on unofficial leg on the homeward journey, four were devoted primarily to physical oceanographic measurements.

TL;DR: Rainbow and Phillips as mentioned in this paper have extensive experience of biomonitoring worldwide, and are co-authors of the recent book entitled Biomonitorsing of Trace Aquatic Contaminants.

TL;DR: In this paper, the authors evaluated biological criteria for defining water quality and the presence of acceptable levels of benthic resources for estuarine macrobenthic communities of the lower Chesapeake Bay, USA.

TL;DR: A survey was organized to determine the extent and degree of contamination by petroleum hydrocarbons and trace metals that entered the Gulf from the massive oil spill and oil field fires in Kuwait as mentioned in this paper.

TL;DR: In this article, the most commonly encountered herbicides were atrazine, simazine, alachlor, metolachlor and molinate in the Ebro delta on the Eastern Coast of Spain, the Rhone delta in the South of France, the River Po, Italy/the Northern Adriatic Sea, the Thermaikos and Amvrakikos Gulfs in Greece and the Nile delta in Egypt.

TL;DR: In this article, a monitoring program conducted in the Bay of Arcachon between 1979 and 1991 revealed an increase of copper content in oysters harvested in a zone located in the vicinity of marinas and mooring areas.

TL;DR: The toxicity of arsenicals is highly dependent upon the nature of the compounds, particularly upon the valency state of the arsenic atom, and compounds containing trivalent arsenic are much more toxic than those with a pentavalent arsenic atom.

TL;DR: The most important physical aspects of the Gulf with respect to effects of marine pollution are its semi-enclosed, shallow nature and its arid setting as discussed by the authors, which has a low rate of water exchange, and large parts of it experiences extremes of salinity and temperature which have considerable effect on the marine communities.

TL;DR: In this paper, the seasonal dynamics of net productivity in the Adriatic Sea and in the northern Gulf of Mexico is coherent with the dynamics of freshwater discharge from their major rivers, the Po River and the Mississippi River, respectively.

TL;DR: In this paper, an analysis of covariance (ANCOVA) was used to detect spatial and temporal trends in the livers of Atlantic croaker (Micropogonias undulatus) livers.

TL;DR: In this paper, the effects of contaminated sediment on liver cytochrome P4501A (EROD) activity, antioxidant enzymes and oxidative damage (lipid peroxidation) examined.

TL;DR: In 1987, the UK government introduced legislation to control the sale of tributyltin (TBT) based paints, and a monitoring program of waters and surficial sediments from six estuarine river systems was undertaken as discussed by the authors.

TL;DR: In this article, a short review article summarizes the results from long term assessment of an oil spill into a coastal fringe mangrove ecosystem in Panama and concludes that a time period of up to 20 years or longer is required for deep mud coastal habitats to recover from the toxic impact of catastrophic oil spills.

TL;DR: In this article, the development of bioremediation is examined as a prototype for new environmental technologies, which involve interactions between scientific researchers, the public, the media and government regulators.

TL;DR: Site location, weather and occasional large inputs (dumping, washouts, etc.) appeared to be the most important factors controlling debris on Panama's Caribbean beaches.

TL;DR: With a marine area of about 415 000 km 2, the Baltic Sea is the largest body of brackish water in the world as mentioned in this paper, and about 80 million people live in its catchment area, including the Peoples of the Slovak Federal Republic, Norway, Ukraine and part of Belarus.

TL;DR: In this article, the authors collected approximately 200 intertidal and subtidal (surface and subsurface) sediments in the areas of Dawhat al Musallamiyah, Dawhat ad Dafi, and Ras Tanaqib along the Saudi Arabian coast as part of the Nearshore Geochemistry Processes Study (Leg II: 16 March-5 April 1992) of the Mt Mitchell Gulf survey.

TL;DR: A statistical analysis of 45 oil spills shows a weak log-log correlation between spill volume and numbers of seabirds killed as discussed by the authors, which cannot be used to predict mortality and loses its significance if one extreme case is omitted.

TL;DR: The Gulf's biological character is briefly reviewed to provide a background to the main habitats and their condition, for the papers in this Special Issue as discussed by the authors, where the Gulf's marine resources are described in the context of possible environmental consequences of the 1991 Gulf War.

TL;DR: Year after the spill, the increased number of injuries and associated reduction in colony size, and decreased size of gonads (eggs) on oiled reefs can reduce the number of reproductively viable colonies and gametes in coral populations, and ultimately reduce population survival.

TL;DR: Pilot surveys of beaches in islands of the Eastern Caribbean show substantial levels of beach debris, but no long term assessment has been conducted, and driftwood was most common in Dominica.

TL;DR: A survey of Lepsiella vinosa in Southern Australia detected imposex at 14 of 20 sites sampled, suggesting that although tributyltin is important in the development of imposex, other factors including copper, paint matrix and environmental stress may also induce this deformity.

TL;DR: Larsson et al. as mentioned in this paper measured chlorinated pesticides in air from the Greenpeace ship Gondwana between New Zealand and Ross Island, January-March, 1990, and found that the concentrations of DDTs in Antarctic air are similar to those in the Arctic.

TL;DR: Blubber from long-finned pilot whales, Atlantic white-sided dolphins and harbour porpoises caught off the Faroe Islands, and from fin whales, sei whales, and sperm whales from Iceland was analysed for organochlorine pollutants, suggesting differential transfer rates of the two organoch chlorine groups through food webs.

TL;DR: Aliphatic and aromatic hydrocarbons were measured on oil residues from beaches on six islands in Prince William Sound, Alaska in addition to altered products from the Exxon Valdez oil spill of 1989 as mentioned in this paper.

TL;DR: International comparison of residue levels in cetaceans in the recent decade revealed that DDT concentrations in Indian dolphins were comparable to those from other localities whereas PCB levels were low.

TL;DR: In this article, the potential hazards of industrial organic chemicals (71 in total) found in surface waters from several UK estuaries were assessed by consulting published aquatic toxicity data using Quantitative Structure-activity relationships (QSARs) in some cases where no data were available.

TL;DR: This paper features the results of a survey of intensive prawn farms in Western Visayas and Northern Mindanao conducted in 1990, which revealed that to solve the self-pollution characteristic of intensive ponds, the farms utilized some 40 chemical and biological products.

TL;DR: Results confirm that, as with many other gastropod species, imposex in Thais orbita is irreversible, and may be found in populations where TBT contamination is no longer present, Nevertheless, controlled transplantation of T. orbita shows promise as a routine bioindicator of contemporary T BT contamination in southern Australia.
