Predicted temperatures were then adjusted by the difference between the means of the MARMAP bottom temperature data for each site and the means of the predicted temperatures over approximately the first 2 annual cycles of growth for each scallop.
Lines showing the mean annual maximum and minimum temperatures from the MARMAP data from each site were drawn on the graph for reference.
All sampling for this study occurred during daylight hours between March and October and was conducted on 1 of 4 vessels: MARMAP and SEAMAP-SA used the RV Palmetto (1990-2011), and SEFIS used the RV Savannah (2010-11), NOAA Ship Nancy Foster (2010), and NOAA Ship Pisces (2011).
We thank the captains and crews of the RV Palmetto, RV Savannah, NOAA Ship Nancy Foster, and NOAA Ship Pisces, the MARMAP and SEFIS staffs, and the numerous volunteers for making our field work possible.
The initial recruitment predictions were based on estimates of spawning and hatching abundances and life-stage mortality rates derived from the MARMAP and GLOBEC surveys (Tables 1 and 2).

surveys of the continental shelf from Cape Hatteras, North Carolina to Cape Sable, Nova Scotia (1977-1984).
The MARMAP survey and other well-designed fishery-independent surveys are extremely useful for stock assessments because standardized gears are used with known efforts in documented locations, which constitute a statistically valid experimental design that facilitates comparisons among years, areas, and gear types (Collins and Sedberry, 1991).
These data included information from fishery-dependent sources (commercial hook-and-line, trawl, and trap fisheries, and recreational headboats, charter boats, and private boats) and the fishery-independent MARMAP survey.
For fishery-independent modeling, we used values for 1972-78 from Manooch and Huntsman (1977), and we estimated values for 1979-97 from MARMAP
data, 1979-94, (a=-3.
