2002 Research Data  

08/10/02


Date: 08/10/02
Time: 11:31 AM
Latitude/Longitude: 34°, 18 minutes N
75°, 48 minutes W
Ocean Depth: 412.6 m (1,353.3 feet)
Depth of Equipment: 412.6 m (1,353.3 feet)
Water Temperature at Equipment Depth: Unavailable
Wind Speed and Direction: 9.1 knots, NE
Seas: 3- to 4-foot seas

Equipment Used: Otter Trawl

Estimated Catch: See below

Description of catch:

  • 2 Spider crabs
  • 3 Green eyes
  • 1 Sea urchin
  • 3 Sea robins
  • 1 Spotted hake
  • Tube worms
  • Shrimp

Other Observations: This net came up inside-out, so we were surprised to find anything in it! In addition to the catch noted above, we also found lots of black plastic pieces from the float that imploded. The spider crabs’ bodies were about four inches in diameter, but the long legs made the animals about a foot across. The sea robins have pectoral fins that have been modified into "legs" so they can walk along the sea floor.

Time: 3:52 PM
Latitude/Longitude: 34°, 17 minutes N
75°, 50 minutes W
Ocean Depth: 373 m (1,223.4 feet)
Depth of Equipment: 373 m (1,223.4 feet)
Water Temperature at Equipment Depth: Unavailable
Wind Speed and Direction: 12.2 knots, SE
Seas: 2- to 4-foot seas

Equipment Used: Otter Trawl

Estimated Catch: See below

Description of catch:

  • 1 Flounder (right-sided)
  • 2 Slime nose fish
  • 1 Hake
  • 1 Scorpion fish
  • 1 Octopus
  • 1 Tunicate
  • 5 Tube worms
  • 1 Comb jelly
  • Chain dogfish

Other Observations: The trawl across the bottom is 30 minutes, but it took three hours to pull this net. It took over an hour to put the net down and another hour to bring the net up.

Depth of Equipment: 404 m (1,325.1 feet)
Water Temperature at Equipment Depth: Unavailable
Wind Speed and Direction: 8.9 knots, NE
Seas: 2- to 4-foot seas

Equipment Used: Otter Trawl

Estimated Catch: 75 fish of different types, 15 gallons of coral, lots of invertebrates

Description of catch:

  • 3 Hagfish
  • 2 Blackbelly rosefish
  • 13 Spider crabs
  • 18 Squat lobsters
