DESCRIPTION:Dr Tiit Kutser\, visiting professor\, Faculty of Science and T
 echnology\, Estonian Marine Institute\, Department of Remote Sensing and M
 arine Optics\, University of Tartu (Estonia)\n\nShort biography:\nGraduate
 d as a geophysicist from University of Tartu\, Estonia (1990). Obtained Ph
 D in environmental physics from the same university (1997). Won a post-doc
  position in CSIRO Office of Space Science and Applications\, Hobart and C
 anberra\, Australia (1999-2002). Was invited to work in Limnology Departme
 nt at University of Uppsala\, Sweden (2002-2004). Worked in the Estonian M
 arine Institute and it’s predecessors as a student\, junior research fel
 low\, researcher\, senior researcher and lead researcher (research profess
 or) since 1987. The institute is currently part of the University of Tartu
 . The main research fields are related to the optics a remote sensing of c
 omplex coastal and inland waters\, but also include shallow water remote s
 ensing (benthic habitat and bathymetry mapping) and studying the role of l
 akes in the global carbon cycle. Won Estonian National Science Award in th
 e category of exact sciences (2008). Representing Estonian Government in t
 he intergovernmental Group on Earth Observations (GEO). Associate Editor i
 n the Remote Sensing of Environment and in advisory boards of a few other 
 journal\nAbstract:\nRemote sensing of water quality works well in clear op
 en ocean waters where the only optically active substance in water is phyt
 oplankton. Other optically active substances – coloured dissolved organi
 c matter (CDOM) and suspended solids\, are mainly phytoplankton degradatio
 n products and therefore in correlation with phytoplankton biomass\, usual
 ly expressed as concentration of chlorophyll-a. Coastal and inland waters 
 are much more complex: concentrations of optically active substances may b
 e several orders of magnitude higher and do not co-vary. This makes estima
 tion of water properties from remote sensing imagery much more difficult. 
 The same applies to mapping of benthic habitat or bathymetry of shallow ar
 eas of optically complex waters – water transparency is relatively low a
 nd signal from the benthic habitats (seagrass beds\, macroalgae\, corals) 
 is hard to separate from the signal coming from the water column.\nRemote 
 Sensing and Marine Optics Department at Estonian Marine Institute\, Univer
 sity of Tartu\, is one of the largest\, most cited\, and well-equipped gro
 ups in this research field around the Baltic Sea. The seminar will give an
  overview about the achievement of the Department in solving different reg
 ional to global scale problems with remote sensing. Main research topics o
 f the Department area: mapping shallow water benthic habitat (including co
 ral reefs) and bathymetry\, developing methods for recognition and quantit
 ative mapping of harmful algal blooms\, developing remote sensing methods 
 for monitoring coastal and inland water quality\, studying the role of lak
 es in the global carbon cycle. The studies have contributed to development
  of new remote sensing methods\, water monitoring methods for national mon
 itoring program and drinking water industry\, provided data for marine spa
 tial planning\, but also allowed to count all lakes on Earth\, measure the
 ir size and volume and make steps forward in determining the role of lakes
  in the global carbon cycle.\n
