Bacteria release more carbon from the ocean than previously thought（图）
Bacteria release carbon ocean previously thought
2021/4/23
A team led by University of Minnesota researchers has discovered that deep-sea bacteria dissolve carbon-containing rocks, releasing excess carbon into the ocean and atmosphere. The findings ...
Ocean Waters Prevent Release Of Ancient Methane（图）
Ocean Waters Prevent Release Ancient Methane
2018/2/1
Ocean sediments are a massive storehouse for the potent greenhouse gas methane.Trapped in ocean sediments near continents lie ancient reservoirs of methane called methane hydrates. These ice-like wate...
The sun inputs huge amounts of heat to the ocean, heat that would stay near the ocean's surface if it were not mechanically mixed into the deep. Warm water is less dense than cold water, so that heate...
Movement Patterns and Catch-and-Release Impacts of Striped Bass in a Tidal Coastal Embayment in Massachusetts
accelerometers catch-and-release stress
2014/11/5
An investigation into the spatial ecology and effects of catch-and-release angling on the physiology and behavior of striped bass was conducted. Fine-scale behavior was assessed by tagging fish with a...

Phosphorus release with carbonate dissolution coupled to sulfide oxidation in Florida Bay seagrass sediments
Phosphorus release carbonate dissolution
2014/4/17
We hypothesized that CaCO3 dissolution, coupled to sulfide oxidation, is an important mechanism by which
solid-phase inorganic P (iP) becomes available to seagrass in tropical carbonate sediments. To...
The Contribution of Salt Fingers to Vertical Mixing in the North Atlantic Tracer Release Experiment
Salt Fingers North Atlantic
2008/7/16
The North Atlantic Tracer Release Experiment (NATRE) was performed in an area moderately favorable to salt fingers. However, the classic finger signature of a distinct thermohaline staircase caused by...
Release of dissolved organic matter by coastal diatoms
Release of dissolved organic matter coastal diatoms
2014/4/23
Dissolved organic matter (DOM) production was examined in axenic batch cultures of five coastal diatom species. For Chaetoceros decipiens, dissolved organic carbon (DOC) accumulated beginning in late ...

Nitrogen fixation and release of fixed nitrogen by Trichodesmium spp. in the Gulf of Mexico
Nitrogen fixation release fixed nitrogen Trichodesmium spp. Gulf of Mexico
2014/5/4
During a 3-yr study in the Gulf of Mexico, we measured dinitrogen (N2) fixation and nitrogen (N) release by Trichodesmium and compared these rates with water column N demand and the estimated N necess...
