Description

Methods & Sampling

Dataset acquisition description

Ctenophore observations were recorded during ROV Doc Ricketts during dives D856 to D920 (2016), D959 to D965 (2017) and 1240 to 1245 (2019 and 2020). Ctenophores collected with the ROV Ventana were from dives 4213 to 4275 (2019 and 2020) in Monterey Bay offshore of California from 200 to 4000 meters.

The data include the species or lowest classification possible along with the date, time, depth, and temperature where the organism was observed. The timestamp (TapeTimeCode) on the recorded tape is also provided when available. The data include measurements taken by the ROV on the way down and up.

Data Processing Description

Dataset Processing Description

BCO-DMO Data Manager Processing Notes:

Data version 2016-12-22
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* converted date and time to ISO timestamp
* rounded temperature and depth to two decimal places and lat/lon to five.

Data version 2017-10-17 replaces version 2016-12-22
* more data added from newer dives
* data parameter names changed, parameter section updated
* "D" added before dive number to be consistent with CTD dataset.
* observer parameter description removed as it was not included in this version of files.

Data version 2: 2020-12-14 replaces version 1:2017-10-17
* added data from 2019 and 2020 dives
* added D or V to DiveNumber for "Doc Ricketts" and "Ventana", respectively, to agree with CTD dataset.

Data version 3: 2021-01-27 replaces version 2: 2020-12-14
* added data from 2020 and 2021 dives
* added D or V to DiveNumber for "Doc Ricketts" and "Ventana", respectively, to agree with CTD dataset.
* Preserved format in column "DateTime24" which has a variable format ( yyyy-mm-dd HH:MM:SS or HH:MM). Filled in existing column from v1 and v2 "ISO_DateTime_UTC" with a consistent ISO 8601 format with time zone (yyyy-mm-ddTHH:MMZ).
* Lat lon rounded to five decimal places as was done in version 1.
* Made a unique taxa list using the "ConceptName" data column and matched names using the World Register of Marine Species taxa match tool. This will be attached as a supplemental file to this dataset and will include the matched taxonomic identifiers aphiaID, and LSID.

ROV Ventana

Supplied Name:

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.
