. Comparison of remote airborne oceanographic sensors. Aeronautics in oceanography; Oceanography. Figure 15B shows two plumes moving rapidly toward 150° with speeds up to meters per second. In figure 15C the main patch has caught up with the plumes. In figure 15D a large diffused plume again projects from the main dye patch. These photographs suggest turbulent flow accompanied by near-surface jets. Data recorded at ARGUS ISLAND during this period are shown in appendix A. The values averaged over the hour following dye release were: wind toward 150° at 7*7 m/sec, current at 8-meter depth toward 210° at m/sec, and current at 30 meters toward 130° at m/sec. Judging from the area of greatest concentration, the set of the dye patch was initially toward the southeast. Within 30 minutes, how- ever, the direction had changed slightly and the patch drifted more southward. The initial set of the dye patch was apparently due to wind action on the surface layer of water. After the dye diffused downward it began to move more in agreement with currents at the 8- meter depth. The area and concentration of the dye patch determined from photog- raphy are shown in figure 16. Appropriate least-squares regression lines are also shown. The areas were determined from aerial photog- raphy, and concentrations were measured from the boat. The area increased linearly during the 5-hour period; concentration decreased as the nega- tive power of Figure 16 Characteristics of Dye Patch as a Function of Time 26.
