Description

Data are from Niskin bottle sampling on cruises in 1997 to 2004. For corresponding CTD data see files on the US GLOBEC data system. Data are final; see the 1997-2004 Nutrient/Chlorophyll Data Report (below) for details. Data are organised by year, cruise, transect, and station. Station numbers are included for reference to other cruise data.

Methods & Sampling

Dataset acquisition description

The LTOP Nutrient & chlorophyll data were collected by Pat Wheeler (pwheeler@coas.oregonstate.edu). Data are from Niskin bottle sampling on cruises in 1997 to 2004. Complete information on sample collection and analyses is available in the Data Report (PDF)

Data Processing Description

Dataset Processing Description

Complete analyses information is available in the Data Report (PDF).

The nuts_chl_lev0 datafile: nuts_chl.dat file was created with clean_revise_wheeler_nut_chl2.pl v0.5.

BCO-DMO corrected the 2004 Wecoma cruise ID from 'W0409' to 'W0408D'; the data report was updated in June 2012 to reflect this change.

Instruments

Niskin bottle

Supplied Name: Niskin Bottle

Supplied Description:

Niskin bottle cast used to collect water samples for pigment, nutrient, plankton, etc. analysis

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.
