Microscopic organism plays a big role in ocean carbon cycling, Scripps scientists discover
Microscopic organism big role ocean carbon cycling Scripps scientists discover
2014/5/13
It’s broadly understood that the world’s oceans play a crucial role in the global-scale cycling and exchange of carbon between Earth’s ecosystems and atmosphere. Now scientists at Scripps Institution ...
Carbon cycling hysteresis in permeable carbonate sands over a diel cycle: Implications for ocean acidification
Carbon cycling hysteresis permeable carbonate sands over a diel cycle ocean acidification
2014/4/2
Dissolved inorganic carbon, dissolved oxygen, H+, and alkalinity fluxes from permeable carbonate sediments at Heron Island (Great Barrier Reef) were measured over one diel cycle using benthic chambers...
The cold-water coral community as a hot spot for carbon cycling on continental margins: A food-web analysis from Rockall Bank (northeast Atlantic)
The cold-water coral community carbon cycling continental margins: A food-web analysis Rockall Bank
2014/4/17
We present a quantitative food-web analysis of the cold-water coral community, i.e., the assembly of living corals, dead coral branches and sediment beneath, associated with the reef-buildingLophelia ...
Oxygen as a control on sea floor biological communities and their roles in sedimentary carbon cycling
Oxygen sea floor biological communities sedimentary carbon cycling
2014/4/22
13C tracer experiments were conducted at sites spanning the steep oxygen, organic matter, and biological community gradients across the Arabian Sea oxygen minimum zone, in order to quantify the role t...
Pathways of anaerobic carbon cycling across an ombrotrophic-minerotrophic peatland gradient
Pathways of anaerobic carbon cycling an ombrotrophic-minerotrophic peatland gradient
2014/4/22
Peatland soils represent globally significant stores of carbon, and understanding carbon cycling pathways in these ecosystems has important implications for global climate change. We measured aceticla...
Virus and bacteria dynamics of a coastal sediment: Implication for benthic carbon cycling
Virus and bacteria dynamics coastal sediment Implication for benthic carbon cycling
2014/5/19
We measured microbial heterotrophic activity, bacteria, and virus-like particle (VLP) abundance in homogenized, undiluted, and anoxic enclosures of sediment collected at a coastal station. The bacteri...
Relationship between bacterial community structure, light, and carbon cycling in the eastern subarctic North Pacific
bacterial community structure light carbon cycling eastern subarctic North Pacific
2014/5/19
Biogeochemical controls on the community structure of heterotrophic marine bacteria are not well understood, and these organisms play a critical role in the global carbon cycle. Through terminal restr...
Planktonic carbon cycling and transport in surface waters of the highly urbanized Hudson River estuary
Planktonic carbon cycling and transport surface waters highly urbanized Hudson River estuary
2014/5/21
We examined variations in organic carbon (OC) pools and microplanktonic carbon fluxes at three stations in the Hudson River estuary during 12 cruises between Octobers of 1996 and 1998. Phytoplankton b...
