This report describes climatological mean monthly distributions of pH, total carbon dioxide concentration, and the degree of CaCO3 saturation for the global surface ocean waters (excluding coastal areas) to depths of approximately 160 feet (50 meters).
The carbonate system of the Baltic Sea is strongly influenced by the input of low salinity waters during spring and summer originating from the Bothnian Sea, the Gulf of Finland and the Gulf of Riga as well as by the input of high salinity waters during autumn and winter originating ...
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, ...
Sea urchin larvae from the Mediterranean Sea survived at higher rates under ocean acidification conditions, but they grew smaller. Warmer temperatures increased survival and growth rates of the larvae. The results suggest that ocean acidification and warming could boost populations of the sea urchin, increasing its impact on shallow Mediterranean ...
Diversification of the marine biosphere is intimately linked to the evolution of the biogeochemical cycles of carbon, nutrients, and primary productivity. Analysis of the ratio of carbon-to-phosphorus buried in sedimentary rocks during the past 3 billion years indicates that both food quantity and, critically, food quality increased through time as ...
Bryozoan colonies that came from larger larvae survived better, grew faster, and reproduced sooner or produced more embryos than colonies that came from smaller larvae. These effects crossed generations, with colonies from larger larvae themselves producing larger larvae.
This study estimated vertical and lateral diffusion coefficients for the Scotian Shelf region using a numerical 2-D approach. It also estimates cross-shelf transport of carbon and nutrients and provides a potential mechanism for CO2 outgassing on the shelf.
The services of ecological systems and the natural capital stocks that produce them are critical to the functioning of the Earth's life-support system. They contribute to human welfare, both directly and indirectly, and therefore represent part of the total economic value of the planet. This study estimated the economic value ...
Small phytoplankton (pico-, nano- and microphytoplankton) play an important role in uptake of carbon dioxide on the Scotian Shelf.
