SoundHAB: Noctiluca vs brown

[Jack Rensel]

It feeds on several types of plankton and is loaded with ammonium at times
too.  See http://botany.si.edu/references/dinoflag/Taxa/Nscintillans.htm

"This large cosmopolitan species is phagotrophic, feeding on phytoplankton
(mainly diatoms and other dinoflagellates), protozoans, detritus, and fish
eggs (Fig. 2)(Dodge 1982; Fukuyo et al. 1990; Hallegraeff 1991; Taylor et
al. 1995; Steidinger & Tangen 1996)."

Quarter Master Harbor at 12:30 today
 Away from the mass of Noctiluca piled at the north end or the  windward
corner of the float.
Does Noctiluca comsum other plankton or just use up all other nutrients?
The sample gathered in a qt jar had the heavy orange scum at the top, this
morning the scum had piled up on the bottom of the jar (in the
frig.)?Reading the other posts I remember that when I sampled from QMH
yesterday I could see tan blobs at different depth drifting by under the
faint orange scum.
I took a sample of just the  tan blobs - looks like bits and pieces of
Cheatoceros!
The net tow sample that we took at 12:30 was very "clean"!    Chaetoceros
rare,  Dinophyses total of 3 and no PN or Alex. Total math not yet done.
All too interesting and I need to move on to other items!
