Description

Macronutrients - Nitrogen, Phosphorus and Silicate concentrations
Note: The lab report for OnDeque2/BATS226 cannot be found.

Note: No date, time, lat, lon contributed for these data

Methods & Sampling

Samples for macronutrient analysis were collected directly from Niskin bottles using a acid-cleaned latex tubing into 60 ml plastic Nalgene bottles that were rinsed with several volumes of sample prior to capping. The Nalgene bottles had been cleaned by soaking for several days in dilute Micro detergent, rinsed with distilled water, then soaked for several days in HCl and then rinsed copiously with deionized water.

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.

Parameters

Date and time formats are described in python strftime() syntax.
