Identifications from biological samples collected with ROV ROPOS during R/V Falkor cruise FK160407 to hydrothermal vents in the Lau Basin, Tonga in April of 2016

Abstract:

Sampling occurred during the R/V Falkor cruise FK160407 to hydrothermal vents in the Lau Basin, Tonga in April of 2016. Biological samples were taken using the ROV ROPOS suction sampler. The data include taxonomic and common name identifications.

Methods & Sampling

ROV ROPOS used a suction sampler or scoop to collect animals. Animals were kept in insulated chambers until recovery from the remotely-operated vehicle on deck.

Pieces of tissue (gill and foot) or whole animals were sampled and preserved in RNALater solution. Samples were stored frozen.

Data Processing Description

BCO-DMO Data Manager Processing Notes:
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* blank values in this dataset are displayed as "nd" for "no data." nd is the default missing data identifier in the BCO-DMO system.
* lat/lons converted to decimal degrees due to character restrictions (degree symbol)
* timestamp in ISO format added
* sample name "1922-9,10,11" changed to "1922-9;10;11" due to delimiter issues with download as a csv option.

Instruments

Remotely Operated Vehicle

Supplied Name: ROV ROPOS

Supplied Description:

Using ROV ROPOS suction sampler

Instrument Type

Generic Name: Remotely Operated Vehicle

Acronym: ROV

Generic Description:

Remotely operated underwater vehicles (ROVs) are unoccupied, highly maneuverable underwater robots operated by a person aboard a surface vessel. They are linked to the ship by a group of cables that carry electrical signals back and forth between the operator and the vehicle. Most are equipped with at least a video camera and lights. Additional equipment is commonly added to expand the vehicle’s capabilities. These may include a still camera, a manipulator or cutting arm, water samplers, and instruments that measure water clarity, light penetration, and temperature.
