A new kind of witchy interaction is underway in the oceans, report the authors of a new paper in Environmental Science & Technology. William G. Sunda and Wei-Jun Cai created a model to predict how CO2 from water pollution—that is, runoff from chemical fertilizers (farms), human waste (sewage), and animal waste (feedlots, ranches), plus nitrogen [...]
As scientists continue to research ways in which the oceans are changing – and what these changes mean for fish populations, three new research projects will receive funding to examine the effects of ocean acidification on fisheries, and the coastal economies that depend upon them. Ocean acidification occurs when the ocean absorbs carbon dioxide from [...]
An increasingly warm climate is worsening the problem of harmful Great Lakes algae blooms by boosting the intensity of spring rains that wash phosphorus into the waters, a scientist said Wednesday during a conference for advocates and policymakers. The trend is likely to continue over the coming century, heightening the urgency to control runoff of [...]
To anyone who has spent a languid summer afternoon tumbling in the waves on South Beach or watched the earth’s closest star dip into the horizon at Menemsha, the ocean can seem eternal and unchanging. But scientists are increasingly discovering that human activity is transforming what was once thought to be an invulnerable resource. The [...]
University and NOAA investigators have found seed-like cysts of the toxic alga Alexandrium at all depths in a sediment core taken from Sequim Bay in Puget Sound. The depths in which they found the seeds indicate Alexandrium dates back to the late 1800’s. Correlations between cyst abundance, sea surface temperature, air temperature, and, for a shorter [...]
Atlantic silversides (Menidia menidia) prefer to deposit their eggs on native salt marsh habitat but not invasive salt marsh species, beaches, or shorelines hardened by bulkheads or rip-rap, according to a recent paper by a researcher funded by the National Centers for Coastal Ocean Science. NCCOS-supported research found approximately 94% of M. menidia eggs collected [...]
The importance of the Gulf of Mexico to the US economy is significant. The National Centers for Coastal Ocean Science has invested over $66M in public funds for research into harmful algal blooms, nutrient over-enrichment contributions to hypoxia, ecological effects of sea level rise (EESLR), and coral reefs in the Gulf of Mexico since 1990. [...]
Skin lesions on coastal dolphins are associated with water that’s colder and has lower salinity, say researchers at the National Centers for Coastal Ocean Science. They analyzed photographs collected during routine monitoring studies of dolphins in estuaries and coastal waters of South Carolina, Georgia and Florida and found that in all three sites, the prevalence of skin lesions [...]
