Description

Sampling information from mussels 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 length, height, width, Phylum, Class, Order, Family and Genus.

Methods & Sampling

Mussel 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, the bushmaster junior, suction apparatus or net scoops:

Mussel Pot – The mussel pot is a 12-quart aluminium-clad stainless steel pot with a twistable handle connected to a Kevlar bag insert. It is used to sample mussel beds and associated communities. The pot is deployed over the select mussel patch using the submersible or ROV manipulator, then collects the enclosed assemblage by cinching the Kevlar bag closed by turning the handle. This method allows for quantitative analysis of deep-sea mussel bed communities.
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.
Slurp – This is simply the term used for suction sampler that attached to the submersible or ROV and collected organisms by suctioning them into an enclosed container.

Instruments

Bottom Sediment Grab Samplers

Supplied Name:

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.

Bushmaster

Supplied Description:

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.

Sediment suction sampler

Supplied Name: Slurp

Supplied Description:

Instrument Type

Generic Name: Sediment suction sampler

Generic Description:

Devices that collect samples from the sediment layer surface using suction. The mechanism of suction can be accomplished by either vacuum, by pressure difference between the air inside the sampler and surrounding water, by pumping water directly into the sampler, or by under pressure air to elevate the sediment inside the sampler. Devices are typically diver- or remotely-operated.
