2002 Research Data  

08/13/02

Date: 08/13/02
Time: 8:02 AM
Latitude/Longitude: 33°, 33 minutes N
76°, 28 minutes W
Ocean Depth: 1474 m
Depth of Equipment: 1 m (3.28 feet—surface reading)
Water Temperature at Equipment Depth: 8.5°
Wind Speed and Direction: 11 knots, NE
Seas: Calm

Equipment Used: Submersible

Estimated Catch: Fish, coral, brittle star

Description of Catch: None provided

Other Observations: This is the first proof we have of lophelia at this site. We caught a large (16 inches?) scorpion fish, as well as a small juvenile blackbelly rosefish. The coral pieces had polycheate worms, gastropods, and brittle stars on them. We also recorded a crab that we have not seen before. We hope the footage from the sub will be good enough to identify it accurately.



Date: 08/13/02
Time: 4:05 PM
Latitude/Longitude: 33°, 30 minutes N
76°, 55 minutes W
Ocean Depth: 78.4 m (257 feet)
Depth of Equipment: 78.4 m (257 feet)
Water Temperature at Equipment Depth: 23.7 degrees Celsius
Wind Speed and Direction: 9 knots, WSW
Seas: 2-foot seas

Equipment Used: Submersible

Estimated Catch: 1 greater soapfish, 1 scallop shell

Description of catch: None provided

Other Observations: Liz and Fritz had a glorious dive. They were never deep enough to be in complete darkness. They saw more than 60 species of fish, including jacks, reef butterfly fish, moray eels, and three lionfish! The lionfish are a non-native species. We do not really know how they got here because they are from the Pacific. They are venomous and could cause problems on our reef.


Date: 08/13/02
Time: 10:23 PM
Latitude/Longitude: 33°, 29 minutes N
76°, 56 minutes W
Ocean Depth: 83 m (272 feet)
Depth of Equipment: 1 m (3.28 feet—surface reading)
Water Temperature at Equipment Depth: Unavailable
Wind Speed and Direction: 13.6 knots, S
Seas: 2-foot seas


Equipment Used: Neuston Net

Estimated Catch: Jack, flying fish

Description of catch: None provided

Other Observations: These fish came from some very small pieces of sargassum. We also kept samples of the two species of sargassum that we caught.


Date: 08/13/02
Time: 11:15 PM
Latitude/Longitude: 33°, 30 minutes N
76°, 59 minutes W
Ocean Depth: 57.5 m (188.6 feet)
Depth of Equipment: 1 m (3.28 feet—surface reading)
Water Temperature at Equipment Depth: Unavailable
Wind Speed and Direction: 12 knots, S
Seas: 1-foot seas


Equipment Used: Dip nets with lights

Estimated Catch: Several species of flying fish, a halfbeak, four crabs, a bur fish, a long-billed spearfish, four file fish, a squid, a juvenile sailfish, an eel

Description of catch: None provided

Other Observations: We used dip nets through the night, from about 11:15 PM until about 3:00 AM. When we "fish" this way, we tie lights to the side of the boat and use long-handled nets to try and catch the stuff that swims close to the ship. Your arms get very tired after reaching over the side for a while! The second night watch got to see a small loggerhead turtle swim by.
