Description

This dataset contains measurements from Niskin bottle samples from R/V New Horizon cruise NH1417 from August 18th to September 16th of 2014 in the Eastern Pacific between San Diego and Hawaii. The R/V New Horizon cruise NH1417 was a Nutrient Effects on Marine microOrganisms (NEMO) cruise.

Measurements from Fast Repetition Rate Fluorometry (FRRF): initial fluorescence, maximum photochemical efficiency of photostream II, and functional absorption of cross-section.

CTD measurements: temperature, salinity, pressure, PAR, in-situ chlorophyll a, dissolved oxygen, fluorescence.

Derived values: Extracted chlorophyll a, 15N2 enrichment, 14C primary production.

Methods & Sampling

Dataset acquisition description

Samples were collected using standard oceanographic techniques. A CTD Rosette with 24 10L Niskin bottles was lowered to the maximum sampling depth and then brought back to the surface. Water was collected during upcasts at discrete depths. Once on board seawater was collected from each bottle for analysis. CTD data included are also from the upcasts.

Data Processing Description

Dataset Processing Description

Data quality flags are the same as defined in the World Ocean Circulation Experiment (WOCE) and are as follows:

Quality flag definitions for water bottles:

1 = Bottle information unavailable.

2 = No problems noted.

3 = Leaking.

4 = Did not trip correctly.

5 = Not reported.

6 = Significant discrepancy in measured values between Gerard and Niskin bottles.

7 = Unknown problem.

8 = Pair did not trip correctly. Note that the Niskin bottle can trip at an unplanned depth while the Gerard trips correctly and vice versa.

9 = Samples not drawn from this bottle.

BCO-DMO Data Manager Processing Notes:
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* Added ISO formatted timestamp from TIME and DATE
* original missing data value '-999' displayed as "nd" for no data in the bco-dmo system

Instruments

CTD - profiler

Supplied Name: CTD Rosette

Supplied Description:

Instrument Type

Generic Name: CTD - profiler

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/130/

Generic Description:

The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. The instrument is lowered via cable through the water column. It permits scientists to observe the physical properties in real-time via a conducting cable, which is typically connected to a CTD to a deck unit and computer on a ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast.

This term applies to profiling CTDs. For fixed CTDs, see https://www.bco-dmo.org/instrument/869934.

Niskin bottle

Supplied Name:

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.
