Summaries of tigerclaw and bushbaby tracers from AUV Clio taken on R/V Atlantis (CliOMZ AT50-10 expedition) from Golfito Costa Rica to San Diego USA in May-June 2023.

Abstract:

This dataset contains processed profiling sensor data from Autonomous Underwater Vehicle (AUV) Clio which was obtained during the CliOMZ AT50-10 expedition onboard R/V Atlantis from May-June 2023. The mean and standard deviation are given for each sensor parameter during the period in which a particular SUPR sample was taken.

Methods & Sampling

The AT50-10 cruise contains Clio dives 031-050. Onboard samplers include: “TIGERCLAW” SUPR sampler and “BUSHBABY” SUPR sampler.

The mean and standard deviation are given for each sensor parameter during the period in which a particular SUPR sample was taken (calculated over a specific valve's pumping time).

Problems/Issues

* Clio031: No data due to ballast issues * Clio032: BUSHBABY was inadvertently programmed with an incorrect port number for the last sample. The port number should have been 4. Optode failed to record data below 400 m * Clio033: Incubation chamber bags did not fill * Clio036: BUSHBABY started pumping too early on port 8 & 9 * Clio041: Vehicle surface an hour early due to a missed sample at 140 m.

Supplied Description:

Instrument Type

Generic Name: AUV Clio

Generic Description:

Clio is an autonomous underwater vehicle (AUV) created to accomplish the dual goals of global ocean mapping and biochemistry sampling. The ability to sample dissolved and particulate seawater biochemistry across ocean basins while capturing fine-scale biogeochemical processes sets it apart from other AUVs. Clio is designed to efficiently and precisely move vertically through the ocean, drift laterally to observe water masses, and integrate with research vessel operations to map large horizontal scales up to a depth of 6,000 meters.
