Shipboard ADCP Measurements
(2010)
Ship-mounted acoustic Doppler current profilers (ADCP) have been used for over 25 years, and have been available on most research ships for much of that time. They are easy to operate on a routine basis, permitting nearly ...
Reference-Quality Water Sample Data: Notes on Acquisition, Record Keeping, and Evaluation.
(2010)
Generating reference-quality water sample data involves procedures learned over years of
experience. Some simple-to-implement aspects of practice do, however, lead to improved reliability
and documentation of water sample ...
A Manual For Acquiring Lowered Doppler Current Profiler Data
(2010)
This manual describes “best practices” for acquiring ocean-velocity data using Lowered Acoustic Doppler Current Profiler (LADCP) systems. Adherence to the recommendations in this manual should help ensure that the acquired ...
CTD Oxygen Sensor Calibration Procedures
(2010)
Oxygen sensors currently afford one of the few oppor
tunities to acquire accurate measurements of a
biogeochemical parameter at the same vertical re
solution as CTD data. Electrochemical cells have
been used to ...
Notes on CTD/O2 Data Acquisition and Processing Using Sea-Bird Hardware and Software (as available).
(2010)
The predecessors of today’s CTD (conductivity-temperature-depth) instruments were introduced in
the 1940s, with modern accurate instruments developed in the 1970s (Emery and Thomson, 1998).
Accuracy standards for these ...
Method for Salinity (Conductivity Ratio) Measurement.
(2010)
The method described here is a modification of th
e technique described by Stalcup (1991). Salinities
for tens of thousands of samples were measured by
the method during the WHP revisit cruises of
the R/V ...
The GO-SHIP Repeat Hydrography Manual: a Collection of Expert Reports and Guidelines, Version 1. [Web Document]
(2010)
Global hydrographic surveys have been carried out approximately every decade since the
1970s through research programs such as
GEOSECS, TTO/SAVE, WOCE / JGOFS, and
CLIVAR. However, global repeat hydrography ...
