Description

Niskin bottle data from 4 CTD casts made during the May 2013 EN524 cruise aboard R/V Endeavor. CTD data were preliminarily processed by the ship's technician during the cruise for initital sensor check. No post-cruise processing or calibrations have been applied.

Methods & Sampling

Dataset acquisition description

Notes from the ship's technician:
No CTD "in water" tests were done during the cruise. Four CTD “on deck” tests were done during the cruise. Sampling casts were to ~72m, or shallower ~4m above bottom. The PAR and SPAR sensors were not installed at all during the cruise. Unless otherwise requested, only Primary Cond is advanced in deck unit. However, our Version 2 of SBE Model 11 plus deck unit can advance both. The Secondary Cond is advanced in processing. Max winch speed was 30 m/min. 12 place frame with 12 OTE external tension sample bottles were used.

CTD gets GPS from bridge switch. Whatever GPS they have selected is the unit that is used (most likely Northstar/Furuno WAAS or Furuno WAAS). 4800 baud.

The seas were calm for most of the cruise with rain and winds to ~25kts on 20 May 2013.

The CTD for all four casts had Pressure, dual Temperature and Conductivity sensors and Pumps, WET Labs C-Star 25cm Transmissometer, WET Labs ECO Fluorometer, Benthos Altimeter, SBE43 Oxygen 1, Oxygen 2 sensors and 12 OTE 10L Niskin bottles on the smaller (12pl) of GSO’s SBE frames. CTD was horizontally mounted.

Data Processing Description

Dataset Processing Description

Notes from the ship's technician:
Data have been preliminarily processed by the ship's technician during the cruise for intitial sensor check. No post-cruise processing or calibrations have been applied. Pressure and blocked transmissometer values from a deck test were used to create con files with updated pressure and transmissometer sensor coefficients. All casts were processed with updated con files (con file used named "EN524_0444d_NoPS.xmlcon").

Configuration Reports (PDF files):
CTD con report
CTD psa report

BCO-DMO Processing Notes:
Modified parameter names to conform with BCO-DMO naming conventions;
Removed several columns from data display: scan; voltages; lat_sd, lat_min, lat_max, lon_sd, lon_min, lon_max (differences between max and min values were all 0.00001 or less);
Added starting date, time, lat, and lon from the CTD file headers;
Added ISO_DateTime_UTC using the original date and time fields.

Instruments

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.
