Methods & Sampling

Dataset acquisition description

Samples were typically taken at the surface and deep chlorophyll maximum using a niskin rosette, all contextual data available (typically temperature and salinity) was deposited with the GenBank Submission for each sequence.

Field sites and sample collection
Five cruises were conducted, two transects from coastal New England to the BATS site (R/V Endeavor cruise EN351 and R/V Oceanus cruise OC413) and three transects across the Florida Straits (R/V Walton Smith cruises WS0503, WS0518, WS0528) with characteristics as in Table 1. Samples were collected in surface and DCM waters using a Sea-Bird Niskin Rosette equipped with standard CTD and PAR detectors (see also below). For DNA extraction samples, 1 l of seawater was gravity filtered through 2 um pore size filters (GE Osmonics, Minnetonka, MN, USA) and then onto a 0.45 um pore size (2001) or 0.2 um pore size (2005) Supor filter (Pall Gelman, Ann Arbor, MI, USA) using vacuum. For FISH samples whole seawater (no size fractionation) was preserved with 1% paraformaldahyde (final concentration) for at least 1 h in the dark at 4°C. For each replicate, volumes of 180 ml or more of seawater were gently filtered onto a 25 mm, 0.2 um Anodisc filter (Whatman, Maidstone, England). The filters were then subjected to an ethanol dehydration series at 50%, 80%, 100% (diluted in sterile, 18.2 ° H2O) for 3 min each and stored at -80°C. Flow cytometry samples were preserved with 0.25% (final concentration) fresh electron microscopy grade glutaraldehyde (Tousimis, Rockville, MD, USA), flash frozen in liquid nitrogen and moved to -80°C for long-term storage.

Data Processing Description

Dataset Processing Description

PCR, cloning and Sanger sequencing for all 18S rDNA
sequences; metagenomic data was produced by multiple
displacement amplification of flow cytometrically sorted
cells with subsequent Sanger and 454-FLX sequencing. See
Cuvelier et al. 2008 and Cuvelier et al. 2010 for greater
detail if desired.

Instruments

CTD Sea-Bird

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird

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

Generic Description:

Conductivity, Temperature, Depth (CTD) sensor package from SeaBird Electronics, no specific unit identified. This instrument designation is used when specific make and model are not known. See also other SeaBird instruments listed under CTD. More information from Sea-Bird Electronics.

Niskin bottle

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.

Photosynthetically Available Radiation Sensor

Supplied Description:

Instrument Type

Generic Name: Photosynthetically Available Radiation Sensor

Acronym: PAR sensor

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/122/

Generic Description:

A PAR sensor measures photosynthetically available (or active) radiation. The sensor measures photon flux density (photons per second per square meter) within the visible wavelength range (typically 400 to 700 nanometers). PAR gives an indication of the total energy available to plants for photosynthesis. This instrument name is used when specific type, make and model are not known.
