JERICO-S3 D5.4 – WP5 - Recommendation for Multiplatform implementation of a biogeochemical NRT observatory. Version 2.1.

Abstract

This Deliverable provides recommendations for multiplatform implementation of near real-time biogeochemical observations within the JERICO-S3 coastal observing framework. Near real-time sensor-based observations of the biogeochemical Essential Ocean Variables (EOVs) – dissolved oxygen, inorganic carbon, dissolved organic matter, and nutrients – are described in the first section of the Main Report. This is followed by five examples from JERICO-S3 Integrated Regional Sites (IRS) and Pilot Supersites (PSS) where multiplatform biogeochemical observations have been carried out, and how multiplatform observations have been performed. The main recommendations, due in part to the high degree of difficulty in making high quality biogeochemical observations, include utilising a well-constrained (near) real-time quality control (QC) system informed by existing datasets and model outputs, validate/compare observations made by complementary observing platforms (including other autonomous platforms, remote sensing products, etc.; i.e., multiplatform approach), and finally validation via traditional oceanographic (research vessel-based) sampling and laboratory analytical techniques.
