Banks of Antarctica's Ross Sea offer rich food source for emperor penguins（图）
Banks Antarctica Ross Sea rich food source emperor penguins
2020/8/14
A new U.S. National Science Foundation-supported study provides some of the most comprehensive evidence to date of the lengths penguins will go for a meal. The results were reported in the journa...

New Study Explains Mysterious Source of Greenhouse Gas Methane in the Ocean
Mysterious Source Greenhouse Gas Methane the Ocean
2016/11/29
For decades, marine chemists have faced an elusive paradox. The surface waters of the world’s oceans are supersaturated with the greenhouse gas methane, yet most species of microbes that can generate ...
New 13-year Study Tracks Impact of Changing Climate on a Key Marine Food Source
Changing Climate Key Marine Food Source
2016/11/4
A new multiyear study from scientists at the Woods Hole Oceanographic Institution (WHOI) has shown for the first time how changes in ocean temperature affect a key species of phytoplankton. The study,...
World’s Richest Source of New In-Water Oceanographic Data Now Operational at Rutgers
New In-Water Oceanographic Data Now Operational Rutgers
2016/5/19
Funded by the National Science Foundation (NSF), the Ocean Observatories Initiative (OOI) is collecting, processing and sharing vast amounts of data on the oceans. The Rutgers team, which includes the...
As one of the most abundant organic compounds on the planet, methanol occurs naturally in the environment as plants release it as they grow and decompose. It is also found in the ocean, where it is a ...
Seamount Mineral Deposits:A Source of Rare Metals for High-Technology Industries
Seamount Mineral Deposits Rare Metals High-Technology Industries
2015/7/7
The near exponential growth in Earth's population and the global economy puts increasing constraints on our planet's finite supply of natural metal resources, and, consequently, there is an increasing...
At different times of the year, prevailing winds blow into Bermuda from open ocean to the south or from the continental United States — an ideal laboratory for studying pollution generated by human ac...
Scientists Identify Source of Mysterious Low-Frequency Sound Heard for Decades in the Southern Ocean
Scientists Identify Source Mysterious Low-Frequency Sound Heard for Decades Southern Ocean
2014/5/13
Scientists have conclusive evidence that the source of a unique rhythmic sound, recorded for decades in the Southern Ocean and called the “bio-duck,” is the Antarctic minke whale (Balaenoptera bonaere...
Denitrification alternates between a source and sink of nitrous oxide in the hypolimnion of a thermally stratified reservoir
Denitrification alternates sink of nitrous oxide
2014/4/2
Nitrogen loading from developed watersheds to aquatic ecosystems can stimulate microbial denitrification, a
process that reduces nitrate (NO{

) to dinitrogen (N2) or nitrous oxide (N2O), the latt...
The “salt wedge pump”: Convection-driven pore-water exchange as a source of dissolved organic and inorganic carbon and nitrogen to an estuary
salt wedge pump Convection-driven pore-water exchange source of dissolved organic inorganic carbon nitrogen to an estuary
2014/4/4
Hypoxia and anoxia in coastal waters have typically been explained by the respiration of sinking organic matter associated with nutrient over-enrichment and phytoplankton blooms. Here, we assess wheth...
Cyanobacteria as a carbon source for zooplankton in eutrophic Lake Taihu, China, measured by 13C labeling and fatty acid biomarkers
Cyanobacteria carbon source zooplankton eutrophic Lake Taihu China measured by 13C labeling fatty acid biomarkers
2014/4/4
Using a combined stable-isotope and fatty-acid approach, we examined carbon-transfer routes from the cyanobacterium Microcystis to zooplankton in eutrophic Lake Taihu, China. Microcystis is generally ...
Assessing nonpoint-source nitrogen loading and nitrogen fixation in lakes using δ15N and nutrient stoichiometry
Assessing nonpoint-source nitrogen loading nitrogen fixation lakes using δ15N nutrient stoichiometry
2014/4/4
Runoff from human-dominated watersheds has greatly altered nitrogen (N) and phosphorus (P) cycling in lakes. Nutrients from human sources are distinct from those from undisturbed ecosystems in several...
