GLOBEC Georges Bank Long-term Moored Array Component

N.E. Peak Mooring Site
41 44' N, 66 32' W

The data reported here are for those data obtained by the N.E.Peak mooring deployment of Nov 1 1995 to Mar 30 1996.

Note:
Sampling rates vary from instrument to instrument and depth to depth.

1. The nominal position of the mooring is the designed deployment site
   and actual deployments varied by about 0.5 nm around this position.
2. Sensor depths are nominal designed depths.  In water sensors vary
   around this designed depth by about 1 m, variation larger at greater
   distance below buoy.
3. Temperatures are listed in the IPTS68 standard, rather than IPT90.
4. Salinity conversion from conductivity was done with PSS78
5. Sensor normalization was done with pre-cruise calibrations, and checked
   with post-cruise calibrations.
6. Only minor editing has been done to remove spikes from records.
7. No corrections have been made to fluorometer and transmissometer data
   to remove biological fouling induced drift.
8. No corrections have been made to salinity for drifts due to biological
   fouling.

The U.S. GLOBEC Georges Bank Program is a large multi- disciplinary multi-year oceanographic effort. The proximate goal is to understand the population dynamics of key species on the Bank - Cod, Haddock, and two species of zooplankton (Calanus finmarchicus and Pseudocalanus) - in terms of their coupling to the physical environment and in terms of their predators and prey. The ultimate goal is to be able to predict changes in the distribution and abundance of these species as a result of changes in their physical and biotic environment as well as to anticipate how their populations might respond to climate change.

The effort is substantial, requiring broad-scale surveys of the entire Bank, and process studies which focus both on the links between the target species and their physical environment, and the determination of fundamental aspects of these species' life history (birth rates, growth rates, death rates, etc).

Equally important are the modelling efforts that are ongoing which seek to provide realistic predictions of the flow field and which utilize the life history information to produce an integrated view of the dynamics of the populations.

The U.S. GLOBEC Georges Bank Executive Committee (EXCO) provides program leadership and effective communication with the funding agencies.

U.S. GLOBEC (GLOBal ocean ECosystems dynamics) is a research program organized by oceanographers and fisheries scientists to address the question of how global climate change may affect the abundance and production of animals in the sea.

The U.S. GLOBEC Program currently had major research efforts underway in the Georges Bank / Northwest Atlantic Region, and the Northeast Pacific (with components in the California Current and in the Coastal Gulf of Alaska). U.S. GLOBEC was a major contributor to International GLOBEC efforts in the Southern Ocean and Western Antarctic Peninsula (WAP).
