¥The 1998 field
season recorded minimum salinity due to the intrusion of Labrador Slope Water which was observed in
the Northeast Channel and eventually came
on to Georges Bank from the Gulf of
Maine. High Calanus
abundance also was noted that year from the
broadscale surveys, as well as high haddock survival.
¥The 1999 season was
warmer, more stratified, and an earlier Calanus bloom was noted which may have led to a 3rd generation (Durbin et al. 2003). Contrasting 1999 with 1998, where haddock survival also was high, will serve to check the
hypotheses relating recruitment to secondary
production.
¥The 1995 season had
low haddock and cod survival during a warm year where Scotian Shelf intrusion was observed in March
and the shelf/slope front moved on-bank to the
60-m isobath during May. What effect did these large physical events have on the
residing populations?
