Effects of phytoplankton community on production, size and export of large aggregates: A world-ocean analysis
phytoplankton community production, size export of large aggregates: A world-ocean
2014/4/17
We recorded vertical profiles of size distributions of large particles (.100mm) to a 1000-m depth in the Atlantic, Indian, and Pacific Oceans and in the Mediterranean Sea with theUnderwater Video Prof...
Environmental control of open-ocean phytoplankton groups: Now and in the future
Environmental control open-ocean phytoplankton groups Now and in the future
2014/4/17
Climate change will alter concurrently many environmental factors that exert control over oceanic phytoplankton. Recent laboratory culture work, shipboard experiments, and field surveys reveal many re...
Can photoinhibition control phytoplankton abundance in deeply mixed water columns of the Southern Ocean?
photoinhibition control phytoplankton abundance deeply mixed water columns the Southern Ocean
2014/4/17
To study how natural Southern Ocean phytoplankton communities acclimate to rapid fluctuations in irradiance levels that result from deep wind-driven mixing of the upper water column, we measured their...
Remineralization of upper ocean particles: Implications for iron biogeochemistry
Remineralization upper ocean particles iron biogeochemistry
2014/4/17
The role of heterotrophic bacteria in iron recycling, the influence of complexation on iron remineralization,and iron mobilization rates from lithogenic vs. biogenic particulate iron (PFe) were examin...
Isotopic niches and trophic levels of myctophid fishes and their predators in the Southern Ocean
Isotopic niches trophic levels myctophid fishes their predators in the Southern Ocean
2014/4/16
We report the trophic structure of a myctophid assemblage by measuring theisotopic niches of 14 species living in Kerguelen waters, southern Indian Ocean. Most of the species show distinct isotopic ni...
Ocean acidification hot spots: Spatiotemporal dynamics of the seawater CO2 system of eastern Pacific coral reefs
Ocean acidification hot spots Spatiotemporal dynamics the seawater CO2 system eastern Pacific coral reefs
2014/4/16
Seawater CO2system dynamics were assessed from eastern Pacific reef sites in Panama ′ over 5 consecutive years(2003–2008) and twice in the Gala ′ pagos Islands (2003 and 2009). The seawater CO2system ...

Researchers and funding agencies justify much oceanographic research by characterizing it as useful for better understanding ocean issues of interest to society at large. However, the direct transfer ...
Ocean Acidification at High Latitudes: The Bellwether
Acidification surface water aragonite underground water sea sea creatures the cold water coral sea urchins mollusks
2015/7/6
Owing to anthropogenic-induced acidification, surface waters of the high latitudes are projected to become persistently undersaturated with respect to aragonite as early as mid-century. Seasonal arago...
Why Corals Care About Ocean Acidification: Uncovering the Mechanism
Stone coral skeletons calcium carbonate carbonate ions the sea the coral
2015/7/6
Stony corals build hard skeletons of calcium carbonate (CaCO3) by combining calcium with carbonate ions derived, ultimately, from seawater. The concentration of carbonate ions relative to other carbon...
Coral Reefs and Ocean Acidification
Coral reef ecosystems ocean acidification calcium carbonate reef-forming organisms
2015/7/6
Coral reefs were one of the first ecosystems to be recognized as vulnerable to ocean acidification. To date, most scientific investigations into the effects of ocean acidification on coral reefs have ...
Quantification of point-source groundwater discharges to the ocean from the shoreline of the Big Island, Hawaii
Quantification of point-source groundwater discharges the ocean shoreline of the Big Island Hawaii
2014/4/18
Aerial thermal infrared imaging has revealed that submarine groundwater discharge (SGD) along the western coast of the Big Island of Hawaii is often focused as point-source discharges that create buoy...
