Unfiltered seawater entered through 15 holes at the head of the tank. Sheets of fluorescent light grating ("egg crates," 8 mm2 holes) wrapped with plastic screens ( mm2 mesh) served as collimators (four up- stream, one downstream). The carrier flow rate was ± .11/s (, n = 10). Average flow velocity in the tank was ± .06 cm/s (n = 10). The test solution (described below) was gravity fed through a 1 mm pasteur pipette at a rate of 50 ± 2 ml/min (n = 10). The nozzle of the pipette was placed in the cross-sectional center of the tank 9 cm off the bottom, roughly at the odor sampling plane of a kg lobster. As a frame of reference for further plume descriptions, the source is at x, y, z = 0. The x-axis is the main axis of the plume, and the y-axis is the other hori- zontal axis. Initial observations of the fluid flow with red dye did not indicate any large asymmetries in the general flow. Red dye was also used in the test solution, and ob- servations showed that the plume was neutrally buoyant with respect to the carrier flow. A total of 63 different sampling sites were chosen in three dimensions (Fig. 1). Sites along the x-axis were 25, 50, and 100 cm from the source. Sites along the y-axis were -10, -5, 0, +5, +10 cm at all x-axis locations. In addition, at x = 50 cm we added y = ±20 cm and at x = 100 cm, y = ±20 and ±30 cm. Sites along the z-axis were 3, 9, 15 cm from the flume bottom, , -6 cm (below) and +6 cm (above) all x, y sites in the z = 0 plane. All sites were sampled sequentially, each for a 3-min pe- riod.
