Log file 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 the dive log from Autonomous Underwater Vehicle (AUV) Clio which was obtained during the CliOMZ AT50-10 expedition onboard R/V Atlantis from May-June 2023. The dataset contains metadata specifying sampling characteristics for each dive.

Methods & Sampling

Dive log for Clio dives 031-050. In depth operation summary for each dive can be found in the Clio Operations Report (see related publications).

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.

BCO-DMO Processing

* Removed headers that were diving up the dive plan file
* Remove total volume calculation at bottom of dive plan file
* Converted dates to ISO format
* Converted lat/lon to decimal degrees
* Removed empty fields from diveplan [DATE TIME RECOVERY] - redundant

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.
