Description

Sampling information from tubeworms and associated organisms collected from different seep sites off the Costa Rica margin. The collections were made aboard R/V Atlantis during 2017 and 2018 using DSV Alvin. In 2019 the collections were made aboard R/V Falkor, using the ROV Subastian. Sampling information contains diameter, length, Phylum, Class, Order, Family and Genus.

Methods & Sampling

Dataset acquisition description

Samples were collected using deep sea vehicle Alvin and ROV Subastian, on R/V Atlantis and R/V Falkor. Methods used for collection involved either grabs, mussel pots, bushmaster junior, suction apparatus or net scoops.

Bushmaster – Original instruments created at Penn State to collect hydrothermal vent and methane seep communities. Hydraulic rods are attached to a very fine mesh that is deployed over the tubeworm patch of interest to collect the tubeworms and associated community. Once the assemblage is enclosed, the net is cinched closed using the submersible or ROV manipulator. Like the mussel pot, this allows for quantitative collections of tubeworm communities.

Data Processing Description

Dataset Processing Description

Samples were processed aboard R/V Atlantis and R/V Falkor and sent back to Temple University, PA, USA for processing.

BCO-DMO processing notes:

Adjusted certain lat and lon values to decimal degrees, with negative values for south and west.
Added ISO_DateTime_UTC column
Reformated date to YYYY-MM-DD
Reformated time to HH:MM
Adjusted column names to comply with database requirements

Instruments

Bottom Sediment Grab Samplers

Supplied Name: Grab

Supplied Description:

Instrument Type

Generic Name: Bottom Sediment Grab Samplers

Acronym: BSGS

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/50/

Generic Description:

These samplers are designed to collect an accurate representative sample of the sediment bottom. The bite of the sampler should be deep enough so all depths are sampled equally. The closing mechanism is required to completely close and hold the sample as well as prevent wash-out during retrieval. Likewise, during descent the sampler should be designed to minimize disturbance of the topmost sediment by the pressure wave as it is lowered to the bottom.

Hydraulic rods are attached to a very fine mesh that is deployed over the tubeworm patch of interest to collect the tubeworms and associated community.
