Report on improved procedures from O2 sensor purchase to data dissemination . MINKE Deliverable D9.7. Version 1.0.

Abstract

This document provides a comprehensive end-to-end guide for the selection, deployment, calibration, data management, and dissemination of dissolved oxygen (O₂) sensors in oceanographic monitoring. It outlines five major stages: (1) needs assessment and sensor selection, (2) sensor preparation and calibration (including use of the EMSO-ERIC calibration bench), (3) deployment and maintenance at sea, (4) data collection, qualification, QA/QC and uncertainty assessment, and (5) data dissemination and community feedback. The report emphasizes the integration of metrological best practices and promotes improved traceability and data quality for Essential Ocean Variables, in line with the objectives of the MINKE project. It also includes detailed flowcharts, sensor comparisons, and operational guidelines for field and lab work.
