Evolution of North Atlantic Water Masses Inferred from Labrador Sea Salinity Series
North Atlantic Water Masses Labrador Sea Salinity Series
font style='font-size:12px;'>
2015/7/20
The Labrador Sea is the coldest and freshest basin of the North Atlantic. Winter cooling in this sea produces Labrador Sea Water. This intermediate water plays an important role in the exchange of hea...
Sea Surface Salinity Trends over Fifty Years Within the Subtropical North Atlantic
Sea Surface Salinity Trends over Fifty Years Subtropical North Atlantic
font style='font-size:12px;'>
2015/7/20
Seawater is a dilute salt solution. The salt or salinity is reduced or elevated as freshwater is added or removed, respectively, through precipitation, evaporation, and sea-ice melting and freezing, a...
Holocene Sea Level Changes Along the United States' Atlantic Coast
Sea Level Changes the United States Atlantic Coast

2015/7/9
Reconstructions of Holocene relative sea level (RSL) have valuable applications in a number of topics within the Earth sciences, including calibrating and constraining geophysical models of Earth's rh...
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...
Nutrient limitation of picophytoplankton photosynthesis and growth in the tropical North Atlantic
picophytoplankton photosynthesis growth in the tropical North Atlantic
font style='font-size:12px;'>
2014/4/21
Identification of the proximal nutrient limiting primary production is a necessary first step toward evaluating
the physiological state of phytoplankton communities and the biogeochemical constraints...
Observations of pigment and particle distributions in the western North Atlantic from an autonomous float and ocean color satellite
Observations of pigment particle distributions
font style='font-size:12px;'>
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...

2014/4/18
In October of 2003 a fleet of autonomous underwater gliders began a time series of transects across the New
Jersey shelf. The gliders are equipped with a conductivity–temperature–depth sensor, and so...
Molecular assessment of phosphorus and iron physiology in Trichodesmium populations from the western Central and western South Atlantic
Molecular assessment phosphorus iron physiology
font style='font-size:12px;'>
2014/4/22
Trichodesmium is capable of responding to low phosphorus (P) and low iron (Fe) concentrations through the
induction of alkaline phosphatase (AP) activity (an enzyme that hydrolyzes inorganic phosphat...
Picophytoplankton cell death induced by UV radiation: Evidence for oceanic Atlantic communities
Picophytoplankton cell death induced oceanic Atlantic communities
font style='font-size:12px;'>
2014/4/23
We analyzed the effect of ambient levels of visible and ultraviolet radiation (UVR) on picophytoplankton cell
death by exposing natural communities of picophytoplankton (Prochlorococcus, Synechococcu...
Archaeal uptake of enantiomeric amino acids in the meso- and bathypelagic waters of the North Atlantic

anoxygenic photoheterotrophic bacteria northwest Atlantic
font style='font-size:12px;'>
2014/4/23
Aerobic anoxygenic photoheterotrophic (AAP) bacteria can use both dissolved organic matter and light for energy
production, but their photosynthesis does not produce oxygen. We measured AAP bacterial...
