Deliverable 3.13 Final implementation and data: Distributed systems for ocean and sea ice
Summary
This deliverable report from the INTAROS Arctic observing project describes the implementation of distributed autonomous systems for measuring ocean and sea ice properties. It documents the platforms, sensors, and data collected during field campaigns.
This document - Final implementation: Data delivery and report on results of the distributed observing systems for ocean and sea ice - describes autonomous components of the Arctic observing system for ocean and sea ice measurements that were developed, tested, and implemented during the INTAROS field work seasons. Instruments and platforms described in D3.13 drifted freely on the sea ice or in the water column (ice tethered platforms, ice buoys and floats), moved along preprogrammed tracks (gliders) or measured autonomously at fixed locations (deep ocean moorings). An autonomous sensor package (FerryBox) and drone-based sensors were used to collect observations from the ships of opportunity or during large observing campaigns like MOSAiC. This document is intended to: − Review status and performance of autonomous mobile and fixed observing platforms and sensors used for collecting ocean and sea ice observations in the Arctic during the INTAROS field work seasons. − Describe performance and data obtained from the ice-tethered IAOOS-Equipex platform used for combined physical, atmospheric and sea ice measurements in the central Arctic Ocean. − Describe performance and data collected with the deep ocean mooring deployed for the second INTAROS field season in the deep Nansen Basin. − Describe performance and data collected by SIMBA (Snow and Ice Mass Balance Array) platforms for sea ice measurements, deployed with INTAROS contribution in the Arctic Ocean. − Describe performance and data collected with new biogeochemical sensors for the FerryBox (pH/carbonate sensor, spectral absorption sensor and microplastic sampler) developed under INTAROS. − Describe the performance of gliders and results from new endurance glider lines established under INTAROS in the northern Fram Strait. − Describe INTAROS contribution to an array of BGC Argo floats in the Baffin Bay observatory, their performance, and collected data. − Assess performance and fitness-to-purpose of the platforms, sensors and systems implemented under Task 3.4 for a future sustained Arctic observing system.
