I will discuss three projects relating to bottom-up controls on
bacterial community composition and bacterial use of dissolved
organic carbon (DOC). A time-series study in the Santa Barbara
Channel illustrated that the bacterial community in this system
displays both repeatable seasonality and long-term and episodic
shifts in composition. A series of field experiments conducted
during a diatom bloom demonstrated that the bloom-associated DOC,
which accumulated in the surface waters as the bloom progressed,
contributed to several metabolic and biogeochemically-relevant
pools. Finally, laboratory experiments using DOC from
nutrient-stressed diatoms showed that DOC bioavailability to
bacteria depends on diatom source species, stressing nutrient, and
the timeframe of interest.
