Methods & Sampling

Dataset acquisition description

Siphonophore observations were recorded in 2019-2022 during ROV Doc Ricketts dives 1240 to 1454 and during the ROV Ventana dives 4213 to 4416 in Monterey Bay offshore of California from approximately 200 to 3000 meters.

Data Processing Description

Dataset Processing Description

BCO-DMO Data Manager Processing Notes:
- added a conventional header with dataset name, PI name, version date;
- added column for ISO8601 Date-Time format;
- rounded temperature and depth to two decimal places;
- added D or V to DiveNumber for 'Doc Ricketts' and 'Ventana' to agree with CTD dataset;
- 2021-11-18: appended additional data from 2020-09-16 to 2021-08-01; updated dataset version number to v2.
- 2022-10-05: appended additional data from 2021-09-23 to 2022-08-15; updated dataset version number to v3.

Instruments

CTD Sea-Bird

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/130/

Generic Description:

Conductivity, Temperature, Depth (CTD) sensor package from SeaBird Electronics, no specific unit identified. This instrument designation is used when specific make and model are not known. See also other SeaBird instruments listed under CTD. More information from Sea-Bird Electronics.

ROV Doc Ricketts

Supplied Description:

Instrument Type

Generic Name: ROV Doc Ricketts

Acronym: Doc Ricketts

Generic Description:

The remotely operated vehicle (ROV) Doc Ricketts is operated by the Monterey Bay Aquarium Research Institute (MBARI). ROV Doc Ricketts is capable of diving to 4000 meters (about 2.5 miles). The R/V Western Flyer is the support vessel for Doc Ricketts and was designed with a center well whose floor can be opened to allow Doc Ricketts to be launched from within the ship into the water below. For a complete description, see: https://www.mbari.org/at-sea/vehicles/remotely-operated-vehicles/rov-doc-ricketts/

ROV Ventana

Supplied Description:

Instrument Type

Generic Name: ROV Ventana

Generic Description:

ROV Ventana is operated by the Monterey Bay Aquarium Research Institute (MBARI). ROV Ventana comes with two manipulators as standard equipment: a Schilling T4, seven-function spatially correspondent arm, and a seven-function Schilling/Oceaneering Atlas Hybrid (rate and spacially correspondent.) Both manipulators can use a variety of end effectors. The ROV has forward-looking camera systems mounted on pan-and-tilt units. The vehicle also has a hydraulic swing arm that deploys from the port side.

Ventana is equipped with a Sea-Bird 19plus V2 CTD package which includes a dissolved oxygen sensor and a transmissometer. Three spatial lasers are mounted on the main camera for quantitative calculations.
