in periods of high RI cyclones paths shift to
the North of Europe and Black Sea rivers gain
less precipitation
Inter annual steric effect winter SST
time-series manifest more clear and coherent
tendencies (Fig. 4c). There is warming up to
1960-s and then cooling up to now Decrease of
1oC is revealed over last 30 years in the Black
Sea Cold Intermediate Layer water mass as well on
surface time-series.

• Summary
• - tide gauge data in Sevastopol, Kaciveli and
  Yalta (central part of the Black Sea) reveal the
  best agreement with mean sea level oscillations
  derived from 12 gauges (correlation coefficient
  r0.85) while Constantsa (western part of the
  Black Sea) and Tuapse (eastern part) have
  correlation coefficient only 0.7
• mutlidisciplinary observations collected at EB
  MHI including data from Oceanographic platform
  will be helpful to assess the influence of the
  following masked factors on sea level
  variations steric effect, wind and atmospheric
  pressure induced set-up, wave induced
  super-elevation, general circulation, coastal
  upwelling, storm surges.
