In Situ Imagery
UAVSAR polarimetric three-color composite image of ocean currents and eddies in the Santa Barbara Channel acquired on September 16, 2009, from the NASA G-III aircraft. Local currents form into two minor convergence zones, shown in the top right and bottom left corners of the image.
OSCAR image of mean surface current speeds in cm/s.
A and B - Climatological averages of QuikSCAT Ocean Wind stress (grey arrows) and curl (color)
C and D - OSCAR surface currents (grey arrows) and surface current magnitude (color)
E and F - SeaWiFS ocean color for February and August 2000–2007.
All three parameters are indicators of ocean current convergence.
SeaWIFS image showing phytoplankton pigment, or chloropjyll, in the Gulf of Maine.
Earth Exploration Satellite Service (EESS) image of global sea surface temperature (SST). Areas of warmer temperature tend to be areas of ocean convergence.
Marine Debris Imagery
Marine debris densities sites at Kure Atoll, Maro Reef, Pearl and Hermes Atoll, and Midway Atoll. Debris density is shown in red.

Side-scanning sonar image of bottom dwelling debris. Pictured here is derelict fishing gear (DFG), or abandoned fishing traps, located in the Gulf of Maine during a NOAA led detection and removel effort.
Side- scanning sonar image of crab pots detected in the James River, Virginia.
