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, ...
Three direct effects of increasing ocean acidification on marine plankton have been recognized: enhanced phytoplankton growth rate, changing elemental composition of primary produced organic matter, and reduced biogenic calcification.
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.
The entire Northeast U.S. Continental Shelf was warm in 2012 compared to the period of 1977-1987. Warm conditions penetrating to the ocean bottom over much of the region. Warming was greatest during the late winter in the southern Middle Atlantic Bight, peaking during summer elsewhere. Bottom waters in the Middle ...
Rivers are a dominant source of sediment entering the ocean. The sediment can be trapped in frontal zones and other oceanographic features, leading to high concentrations. Because of this and other processes, the transport of sediment in river-influenced environments often occurs near the seafloor, rather than the surface.
