    The freshwater composition of waters on the southeast Greenland shelf and slope are described using a set of high-resolution transects occupied in summer 2004, which included hydrographic, velocity, nutrient, and chemical ...
  • Freshwater content variability in the Arctic Ocean 

    Hakkinen, Sirpa M. A.; Proshutinsky, Andrey (American Geophysical Union, 2004-03-31)
    Arctic Ocean model simulations have revealed that the Arctic Ocean has a basin-wide oscillation with cyclonic and anticyclonic circulation anomalies (Arctic Ocean Oscillation (AOO)) that has a prominent decadal variability ...
  • Freshwater export from the Labrador Current to the North Atlantic Current at the Tail of the Grand Banks of Newfoundland 

    Fratantoni, Paula S.; McCartney, Michael S. (2009-11)
    Historical hydrographic data, spanning the period 1896-2006, are used to examine the annual mean and seasonal variations in the distribution of freshwater along and across the shelf/slope boundary along the Labrador and ...
  • Friction, frontogenesis, and the stratification of the surface mixed layer 

    Thomas, Leif N.; Ferrari, Raffaele (American Meteorological Society, 2008-11)
    The generation and destruction of stratification in the surface mixed layer of the ocean is understood to result from vertical turbulent transport of buoyancy and momentum driven by air–sea fluxes and stresses. In this ...
  • Frictional behavior of oceanic transform faults and its influence on earthquake characteristics 

    Liu, Yajing; McGuire, Jeffrey J.; Behn, Mark D. (American Geophysical Union, 2012-04-26)
    We use a three-dimensional strike-slip fault model in the framework of rate and state-dependent friction to investigate earthquake behavior and scaling relations on oceanic transform faults (OTFs). Gabbro friction data ...
  • From salty to fresh—salinity processes in the Upper-ocean Regional Study-2 (SPURS-2) : diagnosing the physics of a rainfall-dominated salinity minimum 

    Schmitt, Raymond W.; Asher, William; Bingham, Frederick; Carton, James A.; Centurioni, Luca; Farrar, J. Thomas; Gordon, Arnold L.; Hodges, Benjamin A.; Jessup, Andrew T.; Kessler, William S.; Rainville, Luc; Shcherbina, Andrey Y. (The Oceanography Society, 2015-03)
    One of the notable features of the global ocean is that the salinity of the North Atlantic is about 1 psu higher than that of the North Pacific. This contrast is thought to be due to one of the large asymmetries in the ...
  • From serpentinization to carbonation : new insights from a CO2 injection experiment 

    Klein, Frieder; McCollom, Thomas M. (2013-08)
    We injected a CO2-rich hydrous fluid of seawater chlorinity into an ongoing, mildly reducing (H2(aq) ≈ 3 mmol/kg) serpentinization experiment at 230°C and 35 MPa to examine the changes in fluid chemistry and mineralogy ...
