System vicarious calibration for ocean color climate change applications: Requirements for in situ data,
(2015)
System Vicarious Calibration (SVC) ensures a relative radiometric calibration to satellite ocean color sensors that
minimizes uncertainties in thewater-leaving radiance Lw derived fromthe top of atmosphere radiance LT. ...
Towards quantifying uncertainty in ocean heat content changes using synthetic profiles.
(2019)
Observational estimates of global ocean heat content (OHC) change are used to assess
Earth’s energy imbalance over the 20th Century.However, intercomparison studies show that the
mappingmethods used to interpolate sparse ...
HF Radar Activity in European Coastal Seas: Next Steps toward a Pan-European HF Radar Network.
(2017)
High Frequency Radar (HFR) is a land-based remote sensing instrument offering a unique insight to coastal ocean variability, by providing synoptic, high frequency and high resolution data at the ocean atmosphere interface. ...
North Atlantic Ocean OSSE system: Evaluation of operational ocean observing system components and supplemental seasonal observations for potentially improving tropical cyclone prediction in coupled systems.
(2017)
Observing System Simulated Experiments (OSSEs) performed during the 2014 North Atlantic
hurricane season quantify ocean observing system impacts with respect to improving ocean
model initialisation in coupled tropical ...
Analysis of Uncertainties Associated to Underwater Hyperspectral Attenuation Measurements.
(2015)
The uncertainty for the underwater hyperspectral measurement of attenuation (ACS) is studied.
The attenuation measurements for standard particles of different diameters (2,5,10,20 mm) by ultra violet visible (UV-Vis) ...
A High Spatial Resolution FBG Sensor Array for Measuring Ocean Temperature and Depth.
(2020)
Exploring and understanding the ocean is an important field of scientific study. Acquiring
accurate and high-resolution temperature and depth profiles of the oceans over relatively short
periods of time is an important ...
Digital underwater signalling standard for network node discovery and interoperability. Edition A, Version 1.
(NATO Standardization Office, 2017)
Present NATO Underwater Communication Capabilities are currently standardised as follows:
- Tactical and safety communication in accordance with STANAG 1074, analogue Voice and Morse
- Distress in accordance with STANAG ...
The JANUS Underwater Communications Standard.
(IEEE, 2014)
There are currently no digital underwater communications
standards. In this paper we describe JANUS, a
simple multiple-access acoustic protocol designed and tested by
the NATO Centre for Maritime Research and ...
Quality Assurance of Oceanographic Observations: Standards and Guidance Adopted by an International Partnership.
(2019)
Scientists who observe and distribute oceanographic data require a process to ensure high-quality data. This process includes quality assurance, quality control, quality assessment, standards, and best practices. In this ...
ITTC Quality System Manual. Recommended Procedures and Guidelines. Guideline: Underwater noise from ships, full scale measurements. Revision 01.
(International Towing Tank Conference, Zurich, Switzerland, 2017)
The purpose of this document is to provide guidance on the available procedures and methodologies for measuring underwater noise from surface ships. For the purposes of this document underwater noise is meant the sound ...
