The mean surface circulation of the North Atlantic subpolar gyre: A comparison of estimates derived from new gravity and oceanographic measurements
(2011-08)
A new mean sea surface topography (MSST) is used to estimate the surface circulation of the subpolar gyre of the northwest Atlantic. The MSST is produced using a new geoid model derived from a blend of gravity data from ...
Madden-Julian Oscillation and sea level: Local and remote forcing
(American Geophysical Union, 2010-01)
The Madden-Julian Oscillation (MJO) is the dominant mode of atmospheric variability in the tropical atmosphere on intraseasonal time scales (i.e., weeks to seasons). This study examines the connection between the MJO and ...

Estimating mixed layer nitrate in the North Atlantic Ocean
(2010)
Here we present an equation for the estimation of nitrate in surface waters of the North Atlantic Ocean (40 degrees N to 52 degrees N, 10 degrees W to 60 degrees W). The equation was derived by multiple linear regression ...
Mapping the relationship between northern hemisphere winter surface air temperature and the Madden-Julian oscillation
(American Meteorological Society, 2011-08)
A regression-based modeling approach is described for mapping the dependence of atmospheric state variables such as surface air temperature (SAT) on the Madden-Julian oscillation (MJO). For the special case of a linear ...
Methodological Underestimation of Oceanic Nitrogen Fixation Rates
(2010-09)
The two commonly applied methods to assess dinitrogen (N(2)) fixation rates are the (15)N(2)-tracer addition and the acetylene reduction assay (ARA). Discrepancies between the two methods as well as inconsistencies between ...
Contrasting biogeochemistry of nitrogen in the Atlantic and Pacific Oxygen Minimum Zones
(2012)
We present new data for the stable isotope ratio of inorganic nitrogen species from the contrasting oxygen minimum zones (OMZs) of the Eastern Tropical North Atlantic, south of Cape Verde, and the Eastern Tropical South ...

Absolute probability estimates of lethal vessel strikes to North Atlantic right whales in Roseway Basin, Scotian Shelf
(2012-10)
Vessel strikes are the primary source of known mortality for the endangered North Atlantic right whale (Eubalaena glacialis). Multi-institutional efforts to reduce mortality associated with vessel strikes include vessel-routing ...
Accelerometer tags: detecting and identifying activities in fish and the effect of sampling frequency
(2013-04)
Monitoring and measuring the behaviour and movement of aquatic animals in the wild is typically challenging, though micro-accelerometer (archival or telemetry) tags now provide the means to remotely identify and quantify ...
