Description

CTD Rosette Bottle Data from New Horizon cruise July 28 - August 12, 2000 (NH0007).

Notes:
(1) Actual Rosette Bottle Number (1-12) is obtained by dividing shown Bottle Position by 2 (e.g., 12 shown = 6).
(2) Chlorophyll readings done by Leah Feinberg.
(3) Chl_QCF is a quality control flag for the extracted chlorophyll data. Flagged 1 for samples that may have been rinsed with unfiltered rinse water.

Methods & Sampling

Notes:
(1) Nutrient samples were collected from most bottles; all nutrient data developed from samples frozen during the cruise and analyzed ashore; data developed by Burke Hales (OSU).
(2) Bottle Salts were run by SIO techs on Guildline Autosalinometer.
(3) sal (sal00) - salinity calculated from primary sensors (C0,T0) differ from bottle salts by less than 0.003 psu.
(4) sal2 (sal11) - salinity calc. from secondary sensors (C1,T1) differ from bottle salts by ca. 0.0088 psu.

Operation Detection Limits for Nutrient Concentrations (Units are micromoles per liter):
      PO4 Range: 0.003-0.004; Mean = 0.004
      NO3+NO2 Range: 0.04-0.08; Mean = 0.06
      Si(OH)4 Range: 0.13-0.24; Mean = 0.16
      NO2 Range: 0.003-0.004; Mean= 0.003

Data Processing Description

BCO-DMO replaced single digit day and month values with 2-digit values (ie. replaced '7' with '07').

08/17/12: BCO-DMO added lat and lon from the NH0007 event log station locations.

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.

Parameters

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