Description

Microphytoplankton station counts for the ANACONDAS cruises
Phytoplankton by species in cells/ml

Methods & Sampling

Dataset acquisition description

Sampled 2-6 liters from Niskin bottle attached to CTD rosette. Filtered through 20 micrometer mesh, to concentrate down to 40 ml, and fixed with acid lugol’s solution. Counted taxa on 1-ml Sedgwick rafter cell via light microscopy at 200x.

Deployment-specific processing description

Notes from original spreadsheet for: MV1110
Station cell counts from the September 2011 ANACONDAS cruise
Counts are 2 liters from CTD cast, filtered and washed through 10 um filters
Cells were fixed with acidified lugol's solution in 50 ml vials
Samples were counted through a 32X objective on a sedgewick rafter hemocytometer

Sampled by IB and AJK
Counted by EJC and AJK

Instruments

CTD Sea-Bird SBE 911plus

Supplied Name: CTD SBE 911plus

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird SBE 911plus

Acronym: CTD SBE 911plus

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/

Generic Description:

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