Aanderaa Oxygen Optodes: Best Practices for Maintaining High Data Quality.
(Aanderaa Data Instruments AS, Bergen, Norway, 2018)This document gives recommendations on field adjustments of oxygen optodes. Done correctly a one or two-point adjustment of an optode will give it almost the same accuracy as when it was factory calibrated. By following ... -
Accuracy assessment of Go Pro Hero 3 (Black) camera in underwater environment. XXIII ISPRS Congress, 12–19 July 2016, Prague, Czech Republic.
(2016)Modern digital cameras are increasing in quality whilst decreasing in size. In the last decade, a number of waterproof consumer digital cameras (action cameras) have become available, which often cost less than $500. A ... -
Accurate oxygen measurements on modified Argo floats using in situ air calibrations.
(2016)Oxygen is an important tracer for biological processes in the ocean. Measuring changes in oxygen over annual cycles provides information about photosynthesis and respiration and their impact on the carbon cycle. Long-term, ... -
ANSI/ASA S1.20-2012. Procedures for Calibration of Underwater Electroacoustic Transducers.
(American National Standards Institute, Inc. (ANSI), Melville, NY, 2012)This standard establishes measurement procedures for calibrating underwater electroacoustic transducers. It is a revision of American National Standard S1.20-1988 (R2003). Both primary and secondary calibration procedures ... -
Best practices for autonomous measurement of seawater pH with the Honeywell Durafet.
(2014)Performance of autonomous pH sensors is evaluated by comparing in situ data to independent bench-top measurements of pH and to co-located pH, O2, and pCO2 sensors. While the best practice is always to deploy a properly ... -
Best Practices for Shipboard Underway Transmissometers. Version 1.
(Florida State University, Center for Ocean-Atmospheric Prediction Studies, Tallahassee, FL, 2020)This best practice document was developed under the Rolling Deck to Repository project by a small working group comprised of the document authors. These recommendations are specifically for transmissometers installed ... -

(State Administration for Market Regulation, People’s Republic of China, 2020)This specification is applicable to the calibration of nutrient analyzers used in oceans. -
Calibration Specification for Seawater pH Analyzer.
(State Administration for Market Regulation, People’s Republic of China, 2020)This specification is applicable to the calibration of seawater pH analyzers. -
IEC 60565-1:2020. Underwater acoustics - Hydrophones - Calibration of hydrophones - Part 1: Procedures for free-field calibration of hydrophones. Edition 1.
(International Electrotechnical Commission (IEC), Geneva, Switzerland, 2020)IEC 60565-1:2020 specifies methods and procedures for free-field calibration of hydrophones, as well as individual electroacoustic transducers that can be used as hydrophones (receivers) and/or projectors (source transducers). ... -
IEC 60565-2:2019. Underwater acoustics - Hydrophones - Calibration of hydrophones - Part 2: Procedures for low frequency pressure calibration. Edition 1.
(International Electrotechnical Commission (IEC), Geneva, Switzerland, 2019)IEC 60565-2:2019 specifies the methods for low frequency pressure calibration of hydrophones at frequencies from 0,01 Hz to several kilohertz depending on calibration method. IEC 60565-2:2019, together with IEC 60565-1, ... -
Instrumenting our oceans for better observation: a training course on a suite of biogeochemical sensors: IOCCP & BONUS INTEGRAL Training Course.
(2019)Ocean properties vary on a number of time-scales and it is necessary to obtain high quality, high resolution (both spatial and temporal) biogeochemical measurements in order to tease out human from naturally-induced changes. ... -
A methodology to uncertainty quantification of essential ocean variables.
(2022)The goal of this study is to provide a universally applicable procedure for a systematic evaluation of in situ measured data from single sensors regarding quantifying the uncertainty of the measurement results. As ... -
Oxygen Optode Sensors: Principle, Characterization, Calibration, and Application in the Ocean .
(2018)Recently, measurements of oxygen concentration in the ocean – one of the most classical parameters in chemical oceanography – are experiencing a revival. This is not surprising, given the key role of oxygen for assessing ... -
Standard Operating Procedure for Flat Port Camera Calibration. Version 0.2.
(GEOMAR Helmholtz Centre for Ocean Research, Kiel, Germany, 2016)This document specifies the practical procedure to obtain good images for geometric camera calibration at GEOMAR. Geometric camera calibration means that for each pixel in the image the associated 3D ray in space is known ... -
