Description

This dataset includes eukaryotic and cyanobacterial DNA sequence data obtained from the upper water column as well as from shallow drifting traps during regular BATS cruises from May 2008-April 2010. Specifically, it contains a complete list of denaturing gradient gel results and the closest sequence matches from the NCBI database for each excised band (phylotype) as well as original denaturing gradient gel images.

Methods & Sampling

Dataset acquisition description

Sampling and Analytical Methodology:
Sampling was conducted monthly from May 2008-April 2010 at the Bermuda Atlantic Time-Series (BATS). Samples were collected for DNA analysis from four depths in the upper water column and from 150 m particle traps. DNA was extracted from these samples and a region of the 18S ribosomal RNA gene for eukaryotes and 16S rRNA gene for cyanobacteria was amplified by PCR using eukaryotic and cyanobacterial primers. Each amplified sample was subjected to Denaturing Gradient Gel Electrophoresis in order to “fingerprint” the community. Individual bands were excised and identified by sequence matching using the NCBI database (http://blast.ncbi.nlm.nih.gov). Quantity One software package was used to determine similarity between samples. The efficiency of recovery was determined by qPCR in order to accurately calculate the DNA present in the water column and DNA flux into particle traps. For further detail please refer to:

Data Processing Description

Dataset Processing Description

Data Processing:
Denaturing gradient gels were imaged and analyzed with the BioRad Fluor-S imager. Bands were selected and matched manually for band matrices included in these data.

BCO-DMO Note: Cruise 242 was on the RV/Oceanus, not the Atlantic Explorer. The cruise id was corrected 5/13/2013. (NJC)

Instruments

Sediment Trap

Supplied Description:

Instrument Type

Generic Name: Sediment Trap

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/33/

Generic Description:

Sediment traps are specially designed containers deployed in the water column for periods of time to collect particles from the water column falling toward the sea floor. In general a sediment trap has a jar at the bottom to collect the sample and a broad funnel-shaped opening at the top with baffles to keep out very large objects and help prevent the funnel from clogging. This designation is used when the specific type of sediment trap was not specified by the contributing investigator.
