Methods & Sampling

Dataset acquisition description

1) Cruise R/V LM GOULD (LMG1110): Samples collected using Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) with a mouth opening of 1-m2 and nine 335μm mesh nets; upper 200 m were sampled with a 2.3 m2 Isaacs-Kidd Midwater Trawl (IKMT) with a 505 µm mesh net. Western Antarctic Peninsula region, Southern Ocean (November-December 2011)

2) Cruise R/V Polarstern (PS-ANT-XVII/2): Samples collected using a Rectangular Midwater Trawl (RMT 1+8) from the upper 200 m. Western Antarctic Peninsula region, Southern Ocean (January 2011)

3) Cruise R/V Umitaka Maru (UM-08-09): Samples collected using a RMT 1+8 from 2,000 m to surface. Indian Sector, Southern Ocean (January 2009)

Data Processing Description

Dataset Processing Description

Molecular genetic (genomic and transcriptomic) data resulting from this project have been submitted to appropriate sections of the NCBI GenBank database, as follows:

The Salpa thompsoni Whole Genome Shotgun project (see Jue et al., 2016) has been deposited at DDBJ/ENA/GenBank Genome section under the Accession No. MKHR00000000. The version described in this paper is version MKHR01000000. The genomic data include the final assembly and annotations, as well as all of the raw data files (genomic and small RNAs). Accession Nos. are assigned to the genomic data submission, as follows: SUBID, SUB1479239; BioProject, PRJNA318929; BioSample, SAMN04870323. The Salp Genome Bioproject information and data are available at https://www.ncbi.nlm.nih.gov/genome/?term=MKHR00000000.

The Salpa thompsoni Transcriptome Shotgun Assembly project (see Batta-Lona et al., 2016) has been deposited at DDBJ/ENA/GenBank under the Accession No. GFCC00000000. The version described in this paper is version GFCC01000000. The transcriptomic data includes raw sequencing data and alignment information. The Bioproject Accession No. is PRJNA279245, which includes RNA-seq data from 48 field-collected specimens, which are assigned Biosample Accession Nos. SAMN05604989 - SAMN05605036. The Salp Transcriptome Bioproject information and data are available at https://www.ncbi.nlm.nih.gov/nuccore/GFCC00000000.

Instruments

Isaacs-Kidd Midwater Trawl

Supplied Name: 2.3 m2 Isaacs-Kidd Midwater Trawl (IKMT) with a 505 µm mesh net

Supplied Description:

Instrument Type

Generic Name: Isaacs-Kidd Midwater Trawl

Acronym: IKMT

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/NETT0071/

Generic Description:

A trawl with a pentagonal mouth opening and a dihedral depressor vane as part of the mouth opening. IKMTs come in various dimensions (refer to individual dataset documentation).

The original IKMTs were 10 foot (304 cm) and 15 foot (457 cm) at the mouth. The 10 foot IKMT net was 31 feet (9.45 m) in length (Wiebe and Benfield 2003).

Midwater Trawl

Supplied Name: Rectangular Midwater Trawl (RMT 1+8)

Supplied Description:

Instrument Type

Generic Name: Midwater Trawl

Acronym: TrawlMid

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/23/

Generic Description:

A mid-water or pelagic trawl is a net towed at a chosen depth in the water column to catch schooling fish such as herring and mackerel. Midwater trawl nets have very large front openings to herd schooling fish toward the back end where they become trapped in the narrow "broiler". The sides of the deployed net are spread horizontally with two large metal foils, called "doors," positioned in front of the net. As the trawler moves forward, the doors, and therefore the net, are forced outward, keeping the net open.
This instrument designation is used when specific make and model are not known.

MOCNESS1

Supplied Name: Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) with a mouth opening of 1-m2 and nine 335μm mesh nets

Supplied Description:

Instrument Type

Generic Name: MOCNESS1

Acronym: MOC1

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/NETT0097/

Generic Description:

The Multiple Opening/Closing Net and Environmental Sensing System or MOCNESS is a family of net systems based on the Tucker Trawl principle. The MOCNESS-1 carries nine 1-m2 nets usually of 335 micrometer mesh and is intended for use with the macrozooplankton. All nets are black to reduce contrast with the background. A motor/toggle release assembly is mounted on the top portion of the frame and stainless steel cables with swaged fittings are used to attach the net bar to the toggle release. A stepping motor in a pressure compensated case filled with oil turns the escapement crankshaft of the toggle release which sequentially releases the nets to an open then closed position on command from the surface. -- from the MOCNESS Operations Manual (1999 + 2003).
