Delayed Mode QA/QC Best Practice Manual Version 3.1

Abstract

This document is the IMOS Ocean Gliders (formerly known as Australian National Facility for Ocean Gliders (ANFOG)) Best Practice manual for delayed mode processed data. IMOS Ocean Gliders is a facility under Australia’s Integrated Marine Observing System (IMOS). IMOS Ocean Gliders, based in the University of Western Australia (UWA), with IMOS National Collaborative Research Infrastructure Strategy (NCRIS) funding, currently deploys a fleet of 11 gliders all around Australia, successfully completing an average of 30 glider missions annually. The data retrieved from the glider fleet contributes to the study of the major boundary current systems surrounding Australia and their links to coastal ecosystem processes. This document describes the quality analyses/quality control (QA/QC) methods and correction procedures employed by IMOS Ocean Gliders for delayed mode glider data files available for public download through the Australian Ocean Data Network (AODN) portal (https://portal.aodn.org.au/) (Figure 1). Information from past IMOS Ocean Gliders’ documents regarding CTD (Gourcuff, 2014a) and Optode corrections (Gourcuff, 2014b), as well as Data Management (Woo et al., 2018) has been updated and incorporated into this document.
