Description

Picoplankton abundance data from the COPAS'08 cruise

Population abundances of Prochlorococcus, Synechococcus, picoeukaryotic phytoplankton and non-chlorophyll containing prokaryotes, "heterotrophic bacteria", analyzed from collected flow cytometry samples.

Methods & Sampling

Dataset acquisition description

The primary goal of the Moore lab on the COPAS cruise was to study the horizontal
and vertical abundance distributions of the picophytoplankton populations along and
across the Patagonia Shelf region with a particular emphasis on the picocyanobacteria.
We collected water samples from roughly 25 stations at five depths: three within the
surface mixed layer, at the chlorophyll max, and immediately below the chlorophyll max.
At each of these five depths 1 mL of water was preserved with 0.125% glutaraldehyde
and frozen in liquid nitrogen for subsequent flow cytometric analysis of the
picophytoplankton populations back at USM. From the carboy CO2 incubation experiments
we preserved water at T0, T24 and T72 from all CO2 pressures for flow cytometric
analysis of the picophytoplankton populations response to increased CO

Instruments

CTD Sea-Bird 911

Supplied Description:

Data were acquired using SeaBird SeaSave v7 for SBE 911 software

Instrument Type

Generic Name: CTD Sea-Bird 911

Acronym: CTD SBE 911

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0035/

Generic Description:

The Sea-Bird SBE 911 is a type of CTD instrument package. The SBE 911 includes the SBE 9 Underwater Unit and the SBE 11 Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 and SBE 11 is called a SBE 911. The SBE 9 uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 and SBE 4). The SBE 9 CTD can be configured with auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). More information from Sea-Bird Electronics.

Flow Cytometer

Supplied Description:

Instrument Type

Generic Name: Flow Cytometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB37/

Generic Description:

Flow cytometers (FC or FCM) are automated instruments that quantitate properties of single cells, one cell at a time. They can measure cell size, cell granularity, the amounts of cell components such as total DNA, newly synthesized DNA, gene expression as the amount messenger RNA for a particular gene, amounts of specific surface receptors, amounts of intracellular proteins, or transient signalling events in living cells.

Niskin bottle

Supplied Name: 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.
