Size composition is similar
from 25-30 m in all three areas.
There are proportionally more small particles in the shallower (15-20
m) layer. At 15-20 m the front and
strat are similar and about 2x the concentration found in the mixed
area. If you go all the way to the
max. concentration at 10 m (see Fig. 3, repeated in next slide), then the
strat. zone is the richest in prey. Only in the strat. area do you see an
appreciable proportion of cod larvae this shallow (10-20 m in Greg’s MOCNESS
tows)—perhaps the light conditions are different. We need to look at light, size of cod, etc. See last figure, from Greg. Is food limiting in any of these
situations at any of these depths when we consider size, turbulence, light,
etc?
