2002 Research Data  

08/06/02

Date: 08/06/02
Time: 10:00 AM
Latitude/Longitude: 33°, 10 minutes N
77°, 21 minutes W
Ocean Depth: 127.8 m (419 feet)
Depth of Equipment: 127.8 m (419 feet)
Water Temperature at Equipment Depth: 21.50 degrees Celsius
Wind Speed and Direction: 15.2 knots, NE
Seas: Fairly calm 4-foot seas

Equipment Used: Submarine Johnson Sea-Link

Estimated Catch: 17 specimens

Description of catch:

  • 9 Galathae crabs
  • 2 Dragonet fish
  • 2 Hermit crabs
  • 1 Pin shell
  • 2 Box crabs
  • 1 unidentified flat spiral shell (resembled the cut-off top of a conch, but was the entire animal)

Other Observations: Sub descended to an area where there was supposed to be an abundance of fish, but instead found a very empty landscape.



Date: 08/06/02
Time: 1:38 PM
Latitude/Longitude: 33°, 14 minutes N
77°, 22 minutes W
Ocean Depth: 41.1 m (135 feet)
Depth of Equipment: 1 m (3.28 feet—surface reading)
Water Temperature at Equipment Depth: 29.56 degrees Celsius
Wind Speed and Direction: 15 knots, NE
Seas: Fairly calm 4-foot seas

Equipment Used: Neuston Net

Estimated Catch: No fish caught

Other Observations: Very royal blue water suggests there is not much in the water for fish to eat. Phytoplankton would make the water appear green.



Date: 08/06/02
Time: 3:01 PM
Latitude/Longitude: 33°, 12 minutes N
77°, 22 minutes W
Ocean Depth: 65.4 m (215 feet)
Depth of Equipment: 1 m (3.28 feet—surface reading)
Water Temperature at Equipment Depth: 29.56 degrees Celsius
Wind Speed and Direction: 15.7 knots, NE
Seas: Fairly calm 4-foot seas

Equipment Used: Neuston Net

Estimated Catch: 1 Coronet fish

Description of catch: The net looked as if it had nothing in it, but when we looked more closely, we found a small, skinny fish that was about 10 cm in length. The specimen was very narrow and resembled a coffee straw. It was a light tan color, and its eyes were one-third of the way back on its body. The mouth was puckered, making it look like it wanted to kiss other fish. The fins were incredibly small and were close to the body. Coronet fish are related to seahorses.



Date: 08/06/02
Time: 3:21 PM
Latitude/Longitude: 33°, 13 minutes N
77°, 23 minutes W
Ocean Depth: 60.7 m (199.1 feet)
Depth of Equipment: 1 m (3.28 feet—surface reading)
Water Temperature at Equipment Depth: 29.56 degrees Celsius
Wind Speed and Direction: 16 knots, N
Seas: Calm 4-foot seas

Equipment Used: Neuston Net

Estimated Catch: 2 specimens

Description of catch:

  • 1 Trigger fish
  • 1 Comb jelly

Other Observations: The trigger fish was about 1.5 cm and was blue with an orange tail. The size of the fish indicates that it was a juvenile. Trigger fish can grow to be an estimated 25-30 cm in length.



Date: 08/06/02
Time: 9:05 PM
Latitude/Longitude: 33°, 13 minutes N
77°, 17 minutes W
Ocean Depth: 76.6 m (251.2 feet)
Depth of Equipment: 76.6 m (251.2 feet)
Water Temperature at Equipment Depth: Unavailable
Wind Speed and Direction: 30 knots, NE
Seas: 4- to 6-foot seas

Equipment Used: Otter Trawl

Estimated Catch: Not provided

Description of catch:

  • Flounder
  • Grunts
  • Squid
  • Lizard fish
  • Rock shrimp
  • Scorpion Fish

Other Observations: There were small clumps of sargassum visible before we put in the net.



Date: 08/06/02
Time: 10:56 PM
Latitude/Longitude: 33°, 13 minutes N
77°, 18 minutes W
Ocean Depth: 76 m (249.3 feet)
Depth of Equipment: 76 m (249.3 feet)
Water Temperature at Equipment Depth: Unavailable
Wind Speed and Direction: 30 knots, NE
Seas: 4- to 6-foot seas

Equipment Used: Otter Trawl

Estimated Catch: Not provided

Description of catch:

  • "Big eyes" fish
  • Tattlers
  • Flounder
  • 2 octopi
  • "High hat" fish
  • Lizard fish

Other Observations: After this net came in, the captain halted catch operations for the evening. The winds were too high and the seas were too rough for us to be on the stern of the ship. Waves continually crashed over the stern, making it hazardous.



Date: 08/06/02
Time: 11:50 PM
Latitude/Longitude: 33°, 14 minutes N
77°, 16 minutes W
Ocean Depth: Unavailable
Depth of Equipment: Unavailable
Water Temperature at Equipment Depth: Unavailable
Wind Speed and Direction: 30 knots, NE
Seas: 4- to 6-foot seas

Equipment Used: None

Estimated Catch: 1 Flying fish

Description of catch: Not provided

Other Observations: A wave washed one flying fish onto our deck. Someone scooped it up so we could use it for our study. We think he is a research volunteer!
