Deliverable 3.14 First implementation and data: Ocean and sea ice

This document First implementation and operational use of the observing systems. Data delivery and report on results of the ocean and sea ice system, describes autonomous components of the Arctic observing system for ocean and sea ice measurements that were implemented during the first field season under INTAROS. Instruments and platforms described in D3.4 drift freely on the sea ice or in the water column (ice tethered platforms, ice buoys and floats), move along preprogrammed tracks (gliders) or measure autonomously at fixed locations (deep ocean moorings). An autonomous sensor package (FerryBox) and drone-based sensors are used to collect observations from the ships of opportunity. This document is intended to: −Review current status of autonomous mobile and fixed observing platforms and sensors used for collecting ocean and sea ice observations in the Arctic during the first INTAROS field season −Describe an ice tethered IAOOS-Equipex platform used for combined physical, atmospheric and sea ice measurements in the central Arctic Ocean and provided data −Describe new deep ocean BGC mooring deployed for the second INTAROS field season in the deep Nansen Basin −Describe SIMBA (Snow and Ice Mass Balance Array) platforms for sea ice measurements, deployed with INTAROS contribution and data provided by them −Describe deployment of new biogeochemical sensors for the FerryBox (pH/carbonate sensor, spectral absorption sensor and microplastic sampler) developed under INTAROS and provided data sets −Describe results from new endurance glider lines established under INTAROS in Fram Strait and north of Svalbard −Describe INTAROS contribution to an array of BGC Argo floats in the Baffin Bay observatory and data provided by the float
