Field observations and results from previous laboratory studies on the effects of turbulence on dinoflagellates have led to a paradigm in phytoplankton ecology that dinoflagellate growth is negatively affected by turbulence. To test the paradigm, 10

A new method of releasing cellular soluble organic matter from microalgae is reported. This method, which could be used to help characterize the production and taxonomic composition of a phytoplankton bloom, was developed in the laboratory to determi

Photoinhibition of mechanically stimulable bioluminescence (MSL) in the heterotrophic dinoflagellate Protoperidinium depressum Bailey was investigated using samples collected from the Massachusetts and southern Texas coasts. The times for both photoi

Ceratium fusus (Ehrenb.) Dujardin was exposed to light of different wavelengths and photon flux densities (PFDs) to examine their effects on mechanically stimulable bioluminescence (MSL). Photoinhibition of MSL was proportional to the logarithm of PF

Day-night changes in the vertical distribution, intensity, and size of bioluminescence flashes were investigated during a series of cruises to the northern Sargasso Sea in 1987 and 1988. Overall, depth integrated bioluminescence potential and flash d

Natural bioluminescence results from the emissions of bioluminescent organisms in the absence of man-made disturbance. Most epipelagic and mesopelagic bioluminescence is caused by planktonic organisms. Limited attempts to measure natural bioluminesce

The vertical structure of bioluminescence potential (BPOT) and flash density (FD) were measured on five cruises to the northern Sargasso Sea in 1987 and 1988. Depth-integrated (0 to 150 m) BPOT did not vary seasonally, remaining within the range 9 to

[1] Methanol is a biogeochemically active compound and a significant component of the volatile organic carbon in the atmosphere. It influences background tropospheric photochemistry and may serve as a tracer for biogenic emissions. The mass of methan

Temporal and spatial acoustic backscatter estimates of Zooplankton biomass were made using an unmodified hull-mounted 153-kHz acoustic Doppler current profiler (ADCP) during the May 1991 Marine Light-Mixed Layers (MLML) cruises to the North Atlantic.
