Presentation Transcript

  1. The hydrographic research during NABOS 2013 expedition Sergey Kirillov Andrey Pniushkov Ilona Goszczko Ekaterina Bloshkina John Guthrie and Igor Ashik + Vladimir Ivanov

  2. Water sampling with Rosette carrousel L-ADCP L-ADCP

  3. CTD with auxiliary sensors SBE9plus supplies Conductivity, Temperature and Depth measurements with the rate of 24 Hz. In terms of vertical resolution of profile it gives about 4 cm depth intervals. Additional auxiliary sensors: - oxygen - fluorescence - turbidity - transparency - nitrate - altimeter

  4. Expendable Probes eXpendable CTD Profiler (XCTD) eXpendable BathyThermograph (XBT) 31 XBT and 18 XCTD were launched

  5. St.Anna Trough 2008 St.Anna Trougth is one of the key Arctic “hot spots” where cocktail of different water masses is blended 2009 Aksenov et al. 2011

  6. St.Anna Trough RV “Akademik Fedorov”, September 18-19, 2013 RV “Professor Molchanov”, July 11-12, 2013

  7. Atlantic Waters form a specific vertical stratification with temperature maximum below the polar mixed layer The typical vertical structure within the Arctic Ocean deep basin interior

  8. Modification of FSBW and BSBW along the Eurasian continental slope 81N 90E 95E 105E 110E 126E 142E

  9. The lateral mixing induced by double-diffusive processes in the frontal areas

  10. The changes in AWs from 1970s to 2000s AW core temperatures AW upper boundary depth 2000s AW core temperature anomalies 1970s 2000s

  11. The changes in AWs at 126E cross-slope transect vs 1950-1993 vs 2006-2009 The recent thermal state of AWs at 126E is still above an average (the core temperature anomalies are about +0.6) but warming has been ceased since ~2006

  12. The station lists are available in .pdf format …thank to Anna and Nastia

  13. Thank you for your attention
