Bioluminescence from dinoflagellates

However, oceanic bioluminescence in some regions is not due to dinoflagellates but to a number of zooplankton groups (28). The color of the bioluminescence from other organisms varies with taxonomic group (29-32). For an accurate calibration, both the phototube spectral sensitivity and the types of organisms being stimulated must be known. [Pg.238]

Bioluminescence Observations in Isolated Plankters. The use of plankton chambers for the photoelectric recording of flash responses from luminescent dinoflagellates (35, 36), calanoid copepods, and other zoo-plankters (8, 37, 38) is not novel. Although artificial stimuli (electrical and condenser shocks or vacuum and formaldehyde-solution stimulation) were... [Pg.221]

Iselin cruise. On all cruises, cells for calibration were collected in nearsurface waters so that cells would have high levels of bioluminescence (34). The dinoflagellates were collected late in the afternoon by net tows, isolated by pipette into filtered seawater, collected from the same depth, and held in 10-mL pipettes with enlarged tips. After several hours in the dark, and at the time of natural darkness, they were gently introduced a few at a time into the sample chamber intake of the bathyphotometer with the pump running. Batches of the same cells were assayed in the laboratory photometer after being isolated into 3 mL of filtered seawater, held several hours in darkness, and stimulated mechanically to exhaustion. [Pg.244]

Dissolved oxygen sensors, pH electrodes, or specific ion electrodes can be fitted, and a fluorometer for petroleum oils was developed from the chlorophyll sensor (sensitivity, 1 /xg of naphthalene/L). A solid-state bioluminescence sensor was developed (18) with a minimum detection of 5 x 10 W equivalent to about 10 quanta/s at 480 nm, sufficiently low for the detection of a single dinoflagellate flash (19). [Pg.322]
