Marine calcifiers exhibit mixed responses to CO2-induced ocean acidification
Eighteen marine species exposed to ocean acidification conditions for 60 days exhibited a wide range of responses. Ten of the 18 species were affected negatively with lower rates of net calcification and, in some cases, net loss of shell. Those species included temperate corals, pencil urchins, hard clams, conchs, serpulid ...
Estuaries of the northeastern United States: Habitat and land use signatures
Geographic signatures are physical, chemical, biotic, and human-induced characteristics or processes that help define similar or unique features of estuaries along latitudinal or geographic gradients. Geomorphologically, estuaries of the northeastern U.S., from the Hudson River estuary and northward along the Gulf of Maine shoreline, are highly diverse because of a ...
Monitoring Ocean Acidification in Deep Waters of the Stellwagen Bank National Marine Sanctuary: A Progress Report
Influences of oceanographic processes on the biological productivity of the Gulf of Maine
The Gulf of Maine's unusual geography and oceanography make it distinct from other continental shelf ecosystems. It has deep basins, shallow offshore banks that limit water flow between the Gulf and the open Atlantic Ocean, strong tidal mixing of it shallower waters, and a seasonal cycle of intense winter cooling, ...
Coastal Acidification to Rivers: A Threat to Shellfish?
This article provides an overview of how rivers, which tend to be acidic compared to the ocean, affect shellfish, with a focus on the Gulf of Maine.
Effects of elevated temperature and carbon dioxide on the growth and survival of larvae and juveniles of three species of northwest Atlantic bivalves
Ocean acidification conditions and warmer temperatures reduced the survival, development, growth, and lipid synthesis of hard clam and bay scallop larvae. During the juvenile life stages, ocean acidification negatively affected juvenile eastern oysters and bay scallops, but not hard clams. Larvae were substantially more vulnerable to ocean acidication than juveniles ...
Reduced early life growth and survival in a fish in direct response to increased carbon dioxide
Exposure of early life stages of a common estuarine fish (inland silverside) to ocean acidification conditions expected in the world’s oceans later this century reduced survival by 74 percent and growth by 18 percent. The egg stage was significantly more vulnerable than the post-hatch larval stage. These findings challenge the ...
Contemporary Changes of the Hydrological Cycle over the Contiguous United States: Trends Derived from In Situ Observations
Over the contiguous United States, precipitation, temperature, streamflow, and heavy and very heavy precipitation increased during the twentieth century.
An investigation of the calcification response of the scleractinian coral Astrangia poculata to elevated pCO2 and the effects of nutrients, zooxanthellae, and gende
Corals collected in Woods Hole, Massachusetts, exhibited a complex set of responses when exposed to ocean acidification conditions, different nutrient levels, and two different temperatures. For example, female corals were more sensitive than males to elevated CO2 levels. Considering gender and spawning may be important when considering how populations of ...
