  1. ANR-10-EQPX-32-01 • French EQUIPEX call / Equipment - Investments for the future • Duration: Feb 2011- 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 Christine Provost & Jacques Pelon LOCEAN/CNRS LATMOS/CNRS http://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 1.20 m diameter -deployment from twin-otters, ice breakers carries GPS, Iridium, data logger, 2-year battery supply Courtesy J.-C. Gascard Deployed on water

  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: 7 - 800m 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 /atmosphereVertical profiles of temperature and salinity observed in the Canadian basin (left) and in the Eurasian basin (right) . Fresh layer SPW Cold Halocline WPW Thermocline Atlantic Water AW Canadian basin WHOI ITP2 Eurasian Basin

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

  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 propertiesnot easily detectable from satelliteNeed for complementary observations

  10. Platform • Unattended, autonomous, real-time • Ice and ocean measurements : • Ocean profilers: 7 - 1000m 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).
