Dive R497 | |||||||
Dive Plan: This dive is at the extensometer site on the north rift zone of Axial. The elevator was deployed with extensometer#4 in one tube and 3 empty tubes. ROPOS will first take #4 out of the elevator and deploy it, then will recover the other four | |||||||
extensometers that were deployed in '98 and place them in the elevator, where they will be recovered at some point during, or after, the dive. Two Imagenex lines will be run after the extensometer work, then on to CASM | |||||||
At CASM site for sampling and observations: tube worm grab; suction samples of mats, animals, FeO (if any present) and vent fluid. Collect GTBs; recover Vemco and HOBO - all at CASM. Deploy MTR and sample sulfides at CASM as well. | |||||||
Note: Nav fixes not edited in the logs. All fixes were logged, regardless of accuracy. Use the dive plots to determine actual positions. Only positions on NRZ are acoustic nav. All transit and CASM positions are ship at stern. | |||||||

17 | 32 | 1 | 158 | 424216 | 5087322 | Elevator with 4 extensometers aboard into the water at 10:04. Didn't sink. Have to recover to add more weight. | |
17 | 32 | 1 | 158 | 424216 | 5087322 | 10:50. Elevator back on deck. Weights had fallen of. | |
17 | 32 | 1 | 158 | 424216 | 5087322 | 11:55. Elevator back into the briney. There is one extensometer onboard. Idea is to take that one down and deploy, recover others to surface for refurbishing and redeployment. | |

8 | 27 | 1568 | 23 | 420638 | 5095228 | Going a little bit further north, Steve thinks we're cutting through the caldera wall. So we're turning around and going back. | |

8 | 36 | 1543 | 150 | 420638 | 5095228 | Keith had to go southwest to get back to his cage. The tether is ok. | |

Dive Summary: The dive began with the elevator deployment. Got to the bottom. Removed one extensometer from the elevator and deployed it at position 99E5. When we were heading to recover one of the 98 extensometers Frank noticed that the elevator was | |||||||
was floating behind the ship. We recovered the elevator and proceeded to CASM Vent Field. 17 samples were taken t CASM (suctions for animals and fluids), and tube worm grabs. After many hours at CASM we returned to the NRZ extensometer site. | |||||||
The elevator was redeployed and one extensometer was placed in the tube. We lost power to the sub again and the dive was aborted. |
