1) were used to supplement the Ambrose Channel lightship (1941-1972, Fig.
Hourly air temperature (AT) and SST data from NOAA buoys (1985-2002) were used to calculate the observed difference between average monthly AT and average monthly SST for Ambrose Channel (Mar 1985 to Nov 1986), Five Fathom Bank (Mar, Apr 1987), Delaware (Feb to Apr 1991), and Chesapeake (Apr 1993 to Feb 1994, Dec 1994 to May 1995, Feb, Aug 1996).
In contrast, Montauk Point, Ambrose Channel, Barnegat, and Five Fathom Bank all had significantly fewer years in the 1940-1994 period with below normal temperatures and incidence of the mild > cold pattern than would be expected by chance (Binomial tests, P < 0.
9 and 10) were observed at Montauk Point and Ambrose Channel (Table 6).
A latitudinal gradient of recruitment in relation to bottom temperature is indicated by PCA 4 where warmer temperatures in November and December at Montauk Point and Ambrose Channel are correlated with increased recruitment (Tables 6, 7, Fig.
Examination of bottom water temperatures for 1958 at either Ambrose Channel or Montauk Point shows below average water temperatures at both sites.
