Research Tools

ROVs, AUVs, and ABE?

Researchers use instruments anchored to the ocean floor, floating in the water, towed behind ships, and contained in manned and remotely operated submersibles and satellites. Among the alphabet soup of exploratory equipment, ROVs are remotely operated vehicles tethered to a mother ship. AUVs are newer, battery-operated, autonomous underwater vehicles. ABE, or Autonomous Benthic Explorer, is the name of one underwater robot from the Woods Hole Oceanographic Institution that can survey the ocean floor at depths up to 5500 meters with its video cameras, sensors and scanning sonar. Its computers guide it on a pre-determined path. ABE can be deployed at night from the research ship while submersible dives occur during the day, or it can "sleep" on the ocean floor between jobs. To learn more about ABE, check out this Web site: http://www.dsl.whoi.edu/DSL/dana/abe_serious.html

Our Destination

Based on data analyzed by the chief scientist and others for this cruise, we are going to a vent on the South Cleft of the Juan de Fuca Ridge on the Mid-Ocean Ridge.

This image shows a map of the west coasts of Washington State and
part of Oregon. The Juan de Fuca Ridge is approximately 250 miles
west of the coastline, running slightly southwest to southeast.
