Influences of oceanographic processes on the biological productivity of the Gulf of Maine

  • Posted on: Mon, 06/13/2016 - 05:56
  • By: Anonymous

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, ...

Reviewing the impact of increased atmospheric CO2 on oceanic pH and the marine ecosystem.

The world’s oceans contain an enormous reservoir of carbon, greater than either the terrestrial or atmospheric systems. The fluxes between these reservoirs are relatively rapid such that the oceans have taken up around 50% of the total carbon dioxide (CO2) released to the atmosphere via fossil fuel emissions and other ...

Marine biodiversification in response to evolving phytoplankton stoichiometry

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 ...

Offspring size affects the post-metamorphic performance of a colonial marine invertebrate

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.

Short-lived radium isotopes on the Scotian Shelf: Unique distribution and tracers of cross-shelf CO2 and nutrient transport

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 value of the world’s ecosystem services and natural capital

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 ...

Description of the 2012 Oceanographic Conditions on the Northeast U.S. Continental Shelf

  • Posted on: Mon, 06/13/2016 - 05:56
  • By: Anonymous

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 ...

The transport, transformation and dispersal of sediment by buoyant coastal flows

  • Posted on: Mon, 06/13/2016 - 05:56

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.
