Microbial oceanography of the dark ocean’s pelagic realm
Microbial oceanography dark ocean’s pelagic realm
2014/4/17
The pelagic realm of the dark ocean represents a key site for remineralization of organic matter and long-term
carbon storage and burial in the biosphere. It contains the largest pool of microbes in ...
Large, non-Redfieldian drawdown of nutrients and carbon in the extratropical North Atlantic Ocean (46uN): Evidence for dinitrogen fixation?
non-Redfieldian drawdown of nutrients carbon
2014/4/21
Considerable drawdown of total dissolved inorganic carbon (CT) and oversaturation of oxygen (O2
) within a
cold (,15uC) oligotrophic eddy in the extratropical North Atlantic Ocean (46uN, 20.5uW) ind...
Observations of pigment and particle distributions in the western North Atlantic from an autonomous float and ocean color satellite
Observations of pigment particle distributions
2014/4/18
Profiling floats with optical sensors can provide important complementary data to satellite ocean color
determinations by providing information about the vertical structure of ocean waters, as well a...
Scaling of phytoplankton photosynthesis and cell size in the ocean
phytoplankton photosynthesis cell size
2014/4/22
We have determined the scaling relationship between photosynthesis rate and cell size in natural
phytoplankton assemblages of contrasting marine environments. We found that phytoplankton photosynthes...

Determining net dissolved organic hydrographically complex western Arctic Ocean
2014/4/22
Each spring and summer, the Chukchi Sea in the western Arctic Ocean experiences a short but intense
phytoplankton bloom that is controlled by sea ice cover, nutrient availability, and river runoff. D...

Hurricanes Geophysical
2007/3/1
February 28, 2007，Atmospheric scientists have uncovered fresh evidence to support the theory that global warming has contributed to the emergence of stronger hurricanes in the Atlantic Ocean. But the ...
Copepod biodiversity as an indicator of changes in ocean and climate conditions of the northern California current ecosystem
Copepod biodiversity ocean and climate conditions
2014/5/5
We evaluated copepod taxonomic diversity as a potential biological indicator of ocean conditions in the
northeast Pacific Ocean using data collected biweekly between May 1996 and December 2004 and fr...
