1  French EQUIPEX call / Equipment - Investments for the future Duration: Feb Dec 2019 (9 years) Strong coupling between ocean, sea-ice and atmosphere  integrated approach: collection of simultaneous and real-time information about the state of the upper ocean, lower atmosphere and arctic sea-ice  complementary to  satellite observations: measuring parameters that are poorly or not retrieved from satellite measurements  numerical models, (ocean, meteo, chemistry) / data assimilation  Equipment : 40 platforms profiling through ocean, ice and atmosphere ANR-10-EQPX Christine Provost & Jacques Pelon LOCEAN/CNRS LATMOS/CNRShttp://www.iaoos-equipex.upmc.fr

2 Strategy Network of 15 autonomous drifting platforms operating at any given time during 5 years. Proposed spatial distribution. Expected life time : 2 years 6 new platforms every year (exit through Fram S., detroyed by ice ridges) >>> amounting to a total of 40. Logistics: 2 deployment periods per year

3 Based on instrumented surface buoys Deployed on ice Deployed on water 1.20 m diameter -deployment from twin-otters, ice breakers carries GPS, Iridium, data logger, 2-year battery supply Courtesy J.-C. Gascard

4 Platform Unattended, autonomous, real-time Ice and ocean measurements : building upon technological developments and experience acquired during the 4th IPY, EU project Damocles, EU- project ACOBAR ( J.C. Gascard) Ice Mass Balance: IMB- SAMS J. Wilkinson (air, snow, ice, upper ocean) 6 m long chain- thermistors and heaters- 2 cm resolution Surface temperature and pressure sensors. Ocean profilers: m Argo technology (oil bladders and pump- changing flotation through volume changes). SME NKE transmission to buoy through inductive link

5 Autonomous profiling : a big success

6 Precise information about mixed layer, halocline, water masses under halocline >>>>> heat flux from ocean to sea-ice /atmosphere Vertical profiles of temperature and salinity observed in the Canadian basin (left) and in the Eurasian basin (right). Canadian basin WHOI ITP2 Eurasian Basin SPW WPW AW Cold Halocline Fresh layer Atlantic Water Thermocline

7 Ocean-Ice buoy deployed last April from the north pole (Barneo) profiler and cable Surface buoy in place SAMS IMB

8 Buoy drifting towards Fram Strait Recovery late August from KV Svalbard Data from IMB : temperature

9 In the Arctic, mid-latitude pollution and natural aerosol interact with clouds modifying - the equilibrium between phases and - radiative properties not easily detectable from satellite Need for complementary observations

10 Platform Unattended, autonomous, real-time Ice and ocean measurements : Ocean profilers: m POPs technology Ice Mass Balance: IMB SAMS 2 cm resolution Atmosphere Jacques Pelon (LATMOS) (new development) Vertical structure and optical properties of boundary layer, haze, aerosols, clouds.  joint use of Microlidars (like ceilometers in airport technological challenge: T control, limited energy, optical window…) SME CIMEL Optical depth sensors (ODS) (in-lab development derived from an existing space version).

11 Example of particulate scattering ratio obtained with the new prototype from CIMEL (10 mn profile) Altitude (km) Solid-state Microlidar (905 nm) BLayer Elevated aerosol layers
