DESCRIPTION:Please join us as we welcome Dr. Margaret Kalacska\, a Professo
 r in the Department Geography at ºÚÁϲ»´òìÈ University for a seminar titled 'G
 lobal assessment of water resources and aquatic diversity - a remote sensi
 ng approach'. Coffee will be served.\nAbstract\n\nFreshwater ecosystems ar
 e among the most threatened on Earth facing environmental and anthropogeni
 c pressures often surpassing their terrestrial counterparts.  High-resolut
 ion temporal data regarding the change of surface water is lacking at a gl
 obal scale. We created three global surface water extent datasets from the
  Landsat satellite imagery archives from the mid 80s to present. At finer 
 time scales\, our results capture previously recorded events such as the d
 rought of 2010 in the Brazilian Amazon and the extent of flooding in 2012.
  We also show cases where surface water has continued to decrease over tim
 e (e.g. Madagascar). We discuss implications of our findings in terms of t
 he imperilment of endemic aquatic fauna and potential mitigation measures.
