Eukaryotic and prokaryotic microbial taxa retained by wild-caught doliolids collected during bloom events at three different shelf locations in the northern California Current system in June 2019.

Abstract:

Doliolids have a unique ability to impact the marine microbial community through bloom events and high filtration rates. Their predation on large eukaryotic microorganisms is established and evidence of predation on smaller prokaryotic microorganisms is beginning to emerge. We studied the retention of both eukaryotic and prokaryotic microbial taxa by wild-caught doliolids in the northern California Current system. Doliolids were collected during bloom events identified at three different shelf locations with variable upwelling intensity.

Methods & Sampling

Samples were collected during daylight from the R/V Atlantis (AGOR-25) along the Newport Hydrographic (NH) Line at station “NH5” (N 44° 39.084’, W 125° 7.151’) on July 22nd as well as along the Trinidad Head (TR) Line at stations “TR1” (N 41° 3.467, W 124° 16.016) and “TR3” (N 41° 3.448, W 124° 26.7) on July 17th and 19th, respectively.

Doliolids were sampled using a modified coupled Multiple Opening and Closing Net and Environmental Sensing System (MOCNESS). Doliolids were rinsed three times with 0.2 µm filtered seawater to remove unattached microbes, collected in a 1-mL sterile bead-beater tube containing 0.55- and 0.25-mm beads, and then frozen at -80 °C.

Data Processing Description

Seawater and doliolid samples were lysed by beadbeating with 0.55 mm and 0.25 mm sterile glass beads at 30 Hz for 2 min after addition of lysis buffer, freeze-fractured three times, incubated with Proteinase K (VWR Chemicals, Solon, OH) at 20 mg/mL for 1 h at 55 ˚C, and incubated with RNase A at 100 mg/mL for 10 min at 65˚C. The primer pair 515F‐Y/806R was chosen to amplify the 16S rRNA V4 hypervariable region. Reactions were performed with 0.5-2 ng of DNA using the QuantaBio 5Prime HotMasterMix (Qiagen Beverly, MA USA). The Agilent High Sensitivity Kit in the Bioanalyzer (Agilent Technologies, Waldbronn, Germany) confirmed amplicon size. Triplicate reactions from each sample were pooled and paired-end sequenced with Illumina MiSeq v.3 (Illumina, San Diego, CA). Raw sequence data are available in the Sequence Read Archive Project # PRJNA1055560.

Instruments

CTD - profiler

Supplied Name: Niskin CTD Rosette for seawater collection

Supplied Description:

Instrument Type

Generic Name: CTD - profiler

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/130/

Generic Description:

The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. The instrument is lowered via cable through the water column. It permits scientists to observe the physical properties in real-time via a conducting cable, which is typically connected to a CTD to a deck unit and computer on a ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast.

This term applies to profiling CTDs. For fixed CTDs, see https://www.bco-dmo.org/instrument/869934.

MOCNESS

Supplied Name: MOCNESS for animal collection

Supplied Description:

Instrument Type

Generic Name: MOCNESS

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. There are currently 8 different sizes of MOCNESS in existence which are designed for capture of different size ranges of zooplankton and micro-nekton Each system is designated according to the size of the net mouth opening and in two cases, the number of nets it carries. The original MOCNESS (Wiebe et al, 1976) was a redesigned and improved version of a system described by Frost and McCrone (1974).(from MOCNESS manual) This designation is used when the specific type of MOCNESS (number and size of nets) was not specified by the contributing investigator.

Niskin bottle

Supplied Name: Niskin CTD Rosette for seawater collection

Supplied Description:

Instrument Type

Generic Name: Niskin bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0412/

Generic Description:

A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.
