Amended Rolling Deck to Repository (R2R) event log (ELOG) taken on the R/V Atlantic Explorer cruise AE1913 in the Sargasso Sea in June of 2019

Abstract:

The Electronic Logger (ELOG) tracked all deployments on the AE1913 cruise, including CTD, McLane pump, trace metal rosette, and AUV Clio deployment/recoveries, flow-through seawater sampling, sediment trap and plankton nets. Corresponding CTD files from each deployment are recorded in the "comments" column. R/V Atlantic Explorer cruise AE1913 was conducted between June 16th - 28th, 2019 in the Sargasso Sea, beginning at Bermuda Atlantic Time-series Station (BATS) and ending in the northeast shelf of Woods Hole Oceanographic Institution (WHOI).

Data Processing Description

Deployments and recoveries were recorded in the Rolling Deck to Repository Science Eventlogger (Elog, see Ritt (2024) and https://www.rvdata.us/about/event-log). Oceanographic samples were collected onboard the R/V Atlantic Explorer between June 16th - 28th 2019, along a transect beginning at the Bermuda Atlantic Time-series Study (BATS) site and terminating in northeast US continental shelf waters (Woods Hole Oceanographic Institution [WHOI]). Biomass was collected using the biogeochemical AUV Clio. To complement the vertical collection by Clio at Station 1, in situ battery-operated McLane pumps were used for surface biomass collection. The R/V Atlantic Explorer CTD provided physicochemical contextualization. After Clio was deployed, trace metal sampling was performed using a trace metal clean rosette equipped with 12 8L X-Niskin bottles on an Amsteel winch line. Subsamples for dissolved nutrients were collected from 0.2 µm-filtered seawater and stored at -20°C.

Coordinated deployments during AE1913: AUV Clio, McLane large volume pumps, CTD, Trace metal rosette, flow through sampling.

BCO-DMO Processing

* Submitted file "AE1913_R2R_ELOG.csv" was imported into the BCO-DMO data system for this dataset. Values "NaN" imported as missing data values.
** Missing data values are displayed differently based on the file format you download from a BCO-DMO page. They are blank in csv files, "NaN" in MatLab files, etc.

* Column names adjusted to conform to BCO-DMO naming conventions designed to support broad re-use by a variety of research tools and scripting languages. [Only numbers, letters, and underscores. Can not start with a number]
* Column names and order also adjusted to match the elog columns in dataset from cruise AT50-10 https://www.bco-dmo.org/dataset/922260).
* No changes made to data values.

Instruments

AUV Clio

Supplied Name:

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. More information is available at https://www2.whoi.edu/site/deepsubmergencelab/clio/

CTD Sea-Bird SBE 911plus

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird SBE 911plus

Acronym: CTD SBE 911plus

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/

Generic Description:

The Sea-Bird SBE 911 plus is a type of CTD instrument package for continuous measurement of conductivity, temperature and pressure. The SBE 911 plus includes the SBE 9plus Underwater Unit and the SBE 11plus Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 plus and SBE 11 plus is called a SBE 911 plus. The SBE 9 plus uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 plus and SBE 4). The SBE 9 plus CTD can be configured with up to eight auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). more information from Sea-Bird Electronics

McLane Pump

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: McLane Pump

Generic Description:

McLane pumps sample large volumes of seawater at depth. They are attached to a wire and lowered to different depths in the ocean. As the water is pumped through the filter, particles suspended in the ocean are collected on the filters. The pumps are then retrieved and the contents of the filters are analyzed in a lab.

Sediment Trap

Supplied Name: PITS Sediment Traps

Supplied Description:

Instrument Type

Generic Name: Sediment Trap

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/33/

Generic Description:

Sediment traps are specially designed containers deployed in the water column for periods of time to collect particles from the water column falling toward the sea floor. In general a sediment trap has a jar at the bottom to collect the sample and a broad funnel-shaped opening at the top with baffles to keep out very large objects and help prevent the funnel from clogging. This designation is used when the specific type of sediment trap was not specified by the contributing investigator.

Trace Metal Bottle

Supplied Name: trace metal clean rosette equipped with 12 8L X-Niskin bottles

Supplied Description:

Instrument Type

Generic Name: Trace Metal Bottle

Acronym: TM Bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/30/

Generic Description:

Trace metal (TM) clean rosette bottle used for collecting trace metal clean seawater samples.
