Notes

• The image aspect ratio is now correct. The images should be square. This problem within the IDL engine was solved November 2007 by switching to the ferret application to generate the images.
• Images were constructed by first using bi-cubic spline interpolation of the 5-day averaged OI SST grids (produced at 5-day intervals through GOMRMRP funding). The 5-day images were then interpolated linearly in time to produce daily images.
• Information/validation regarding the gridded OI data and the (ASCII) grids are available J. Bisagni at the address above.
• Images are 512 X 512 pixels, possess a resolution of ~7 km and are displayed as .GIF images.
• The archive "switches" from NOAA-11 to NOAA-9 during September 1994 due to the NOAA-11 failure in September 1994.
• The archive currently ends on 5 August 1995 due to the failure of NOAA-9
• *NOTE*: These data are preliminary. Adjustment of data from each satellite (NOAA-9, NOAA-11 and NOAA-14) relative to sea truth values from NOAA data buoys will result in a final calibrated data set at sometime in the future.
• The colorbar used is derived from so-called Pete's Palette, or pete24, and converted to an equivalent palette in the ferret scheme. (See petespalette.spk.

• The image aspect ratio is not quite right. The image should be square. This problem within the IDL engine will be solved shortly (May 20, 2002)

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).
