• Note the apparent high stocks of gt5 ug
  chlorophyll l-1 as estimated from satellite in
  August 1998, and not in August 1999 on the
  northern West Florida shelf similar amounts
  were indeed observed during August 2001 we
  shall find, however, that the 1998 estimates are
  instead CDOM

the 50m and 100m isobaths in summer 1998

The daily three-dimensional trajectory( ) of
neutrally buoyant microflagellates during 5
October-13 November 1998 with respect to A)
location of the water parcel and B) depth during
transit. During maximal upwelling at 4 m day-1,
the innocula of settling diatoms and migrating K.
brevis would have the greatest probability of
retention within the parcel.
