Dive R492 | |||||||
Dive Plan: To map and sample '98 lava flow, SRZ. Sample Dying Vent, if still in existence, and any new vents we might see. Also possible suction sample for Tunnicliffe of diatom/sediment on new lavas. | |||||||
ROPOS Configuration :Suction Sampler, 5 and 7 function arms with claws, cameras, and BioBox with a marker in each side and 4 rock samplers in a bag | |||||||
Note: Nav fixes not edited in the logs. All fixes were logged, regardless of accuracy. Use the dive plots to determine actual positions. | |||||||

22 | 24 | 405 | 289 | 423645 | 5085308 | Dive Summary: Dive R492 was a geology reconnaissance dive of the '98 lava flow on the SRZ, south of the area surveyed in '98. The eastern and western limits of the '98 flow were surveyed, and several targets were added to aid in improving the lava flow | |
outline. Biological and suction samples were taken, as well as many rock samples. A large ventfield was discovered on the east side of the '98 flow in older lava. The vent was named Coquille. Dying Vent was not seen, but Bag City Vent was discovered. |
