Description

U.S. GLOBEC Northeast Pacific, California Current System
Mesoscale Process Studies Chlorophyll a Data

During juvenile salmonid trawling cruises, additional sampling included CTD profiles, neuston net tows, and chlorophyll a water samples. At most stations, data on all parameters were collected.

Acquisition Description

Replicate samples for in-vitro chlorophyll a were collected from 3-m depth with a 1-l Niskin water sampler. Sampling done at all stations at which salmon trawling was done; additional sampling at most stations was a CTD, plankton sampling.

Processing Description

Samples were immediately filtered through GF/F glass fiber filters, then frozen for further analysis in the laboratory. One of two replicates was processed whereas the other was a back up sample. Chlorophyll a was processed using the cold-acetone extraction method and measured with a Turner Designs 10-AU fluorometer (Arar and Collins, 1997).

Instruments

Niskin bottle

Supplied Name: Niskin Bottle

Supplied Description:

Niskin bottle sample at 3-m depth. Replicate samples for in-vitro chlorophyll a were collected from 3-m depth with a 1-l Niskin water sampler.

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.
