levels in coastal waters was higher than last year in both the southern areas of the Finnish Archipelago Sea and the Gulf of Finland.
Led by Lynn Roberts and Ed Bouwer, the researchers track samples at sewage - treatment facilities in Massachusetts and Maryland to determine whether and in what quantities pharmaceuticals are getting through the waste - treatment plants and the extent to which they may be
accumulating in coastal waters.
In fact, Canadian researchers have already moved forward with plans to place sensors along the northern third of the Juan de Fuca plate, and China recently entered the fray with ambitious plans for
observatories in its coastal waters.
RCRVs are among the smaller vessels in the federal fleet, optimized for
work in coastal waters, estuaries, and bays.
To track
changes in coastal waters and predict when seafood species in the region may be safe to consume, it will be necessary to establish a «temporal data set» — that is, to measure the levels and distributions of contaminant radionuclides at a given location over time, he says.
Next, the researchers estimated the chances of one or more of the 13 nonnative bivalve species sold as seafood in the Western U.S. — but not yet
established in coastal waters — being introduced into the regional marine environment.
Tidal wetlands buried 42 percent of the carbon in the study and estuaries buried 38 percent, for a total of 80 percent of carbon
burial in coastal waters.

sampling in coastal waters: «We were thrilled with the first results for robotic sampling coupled with genetic analysis.
Craig Downs, executive director of the Haereticus Environmental Laboratory in Clifford, Va., part of the Global Coral Repository, has been looking at the effect of cosmetic chemical
byproducts in coastal waters for years, in particular how they affect coral reefs.
Nutrient runoff may well be creating dead
zones in coastal waters, but we can't just stop fertilizing our fields; global warming is a serious threat to coral reefs, but we can't just stop emitting greenhouse gases, and at this point it would probably be too late.
Pseudo-nitzschia is a microscopic algae that occurs
naturally in coastal waters, and is of particular concern due to its production of the neurotoxin domoic acid.

«This study shows for the first time that the oxidation of hydrogen sulfide and ammonia from the bottom waters could be a major contributor to lower pH in coastal oceans and may lead to more rapid acidification
in coastal waters compared to the open ocean,» said Cai, the paper's lead author and an expert in marine chemistry and carbon's movement through coastal waters.
