During this dive, we will traverse along ~4.5 km om the northern rim of the Cacho de Coral Seamount between water depths of ~590 m to 212 m. The aim is to cross terrain covered by Alvin Dive 5162 when the pristine reef structure was discovered in April 2023 in order to determine the extent of the reef structure as well as cross the O2 min. layer (350-380 m depth).

The dive is planned to traverse the volcanic terrain on the northern flank of the NW submarine rift zone of Fernandina volcano between ~1690 m and 370 m depth. We will cross specific volcanic constructional features and flow fronts that will provide exposures for rock sampling and hopefully fossil coral deposits. The aim is to collect benthic imagery, coral and lava samples.

During this dive, we will explore two small mound that appear from the bathymetry to look like potential coral areas as observed in the previous dive. The aim is to focus on collecting biological and fossil samples as little sampling has occurred on the western side. If a reef is observed, filming with porta-lander might take place.

During this dive, we will explore the extend of the coral reef discovered during dive S0589. We will dive at a smaller feature and explore its extend and then transit to the larger feature to explore its width and shallow end. The aim is to focus on collecting biological and fossil samples as little sampling occurred on the previous dive. Current may be very strong in this area.

The dive’s objective is to visit an older lava flow on the south flank of Isabela, part of the large terrace structures and take geological samples. The ROV will travel along its length and investigate the types of lava morphologies and vent structures present as well as sample the flow in situ. If time allows, we will also image the shallower wall at the end of the dive and biological samples can be taken.
