The copepod Calanus finmarchicus is the most important and biomass dominant mesozooplankter in the temperate-boreal North Atlantic. C. finmarchicus has an overwintering phase, termed diapause, during which it descends to great depths (300-2000m) and is metabolically quiescent for up to ten months. Changes in the currents at depth due to...
Moored temperature observations were obtained at an array of buoys in the North Atlantic (59° 00.2'-59°10.7'N, 12°27.4'-12°33.6'W) during the Joint Air-Sea Interaction Experiment (JASIN) of 1978. Observations were taken at 10-minute intervals by use of thermistors at 21 depths ranging from 4.5 m to 81.5 m. Plots of temperature as...
Observations of wind speed and direction, air and sea temperature,
and solar radiation were obtained from an array of buoys in
JASIN. The observations were analyzed to show spatial and temporal
variability. Spectra of wind speed and air and sea temperature were
computed to illustrate the distribution of variance over...
The ecology of the North Atlantic right whale (Eubalaena glacialis) was examined at three spatial scales during the summer and early fall on their northern feeding grounds. The diving and foraging behavior of right whales was investigated at spatial scales of hundreds to thousands of meters by tagging right whales...

For many species of marine turtle the characteristics that define pelagic habitat have yet to be fully identified. A better understanding of these habitat characteristics is critical to reduce high seas fisheries interactions with turtles, especially as the status of many turtle populations has placed them on the threatened or...
Sedimentary records from the North Atlantic, instrumental in the development of modern paleo-geomagnetic concepts, show a highly variable field even during times of constant polarity. Yet, our understanding of how the magnetization is acquired in the sediments is poorly understood. Primary magnetizations preserved in deep-sea sediments are known to be...
The western North Atlantic population of the northern right whale (Eubalaena
glacialis) was severely depleted by whaling over the last century. Despite over fifty
years of protection, fewer than four hundred individuals are believed to exist in the
North Atlantic. Relatively little is known about the diving behavior, respiratory
physiology,...
