Data Processing Description

Dataset Processing Description

Measures notes and methods for trace metal concentrations

Notes

1. Iron (Fe) and Aluminum (Al) concentrations are in nmoles/liter 2. The filter column denotes whether or not the sample was filtered, and the filter size used (0 = not filtered; 0.2 = sample passed through 0.2 micron filter and 5 = sample passed through a 5 micron filter).

Methods

These samples were run using the methods found in: a) Measures, C.I., J. Yuan, and J.A. Resing, 1995. Determination of iron in seawater by flow injection analysis using in-line preconcentration and spectrophotometric detection. Marine Chemistry,50:3-12. b) Resing, J.A. and C.I. Measures, 1994. Fluorometric determination of Al in seawater by flow injection analysis with in-line preconcentration. Analytical Chemistry, 66:4105-4111.

Instruments

Niskin bottle

Supplied Name: Niskin Bottle

Supplied Description:

CTD/Niskin Rosette bottles.

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.
