CV

Dr. Arno Behrens, born 1955 in Hamburg

1983: Diploma in Oceanography, University of Hamburg
1983 – 1986: Postgraduate, Alfred-Wegener-Institute for Polar Research, Bremerhaven
1986: Ph.D degree, University of Hamburg
since 1986: Scientist at the Helmholtz-Zentrum Hereon (Hereon, former GKSS)

Dr. Arno Behrens is research scientist at the Hereon Institute of Coastal Systems Analysis and Modeling, currently in the department ‘Hydrodynamics and Data Assimilation’. He is working for many years in the field of wave modelling (mainly with the third generation wave model WAM) and is responsible at Hereon for the development, implementation and maintenance of wave forecast systems that run operational at many institutes worldwide. He was involved in numerous commercial and scientific projects as for example in the EU-projects PROMISE, SEAROUTES, SAFEDOR, ADOPT, FIELD_AC, MYWAVE, DEMARINE and COSYNA. Currently responsible for the operational wave forecast routine for the Black Sea in the frame of the Copernicus Marine Environment Monitoring System (CMEMS) including the Black Sea Monitoring and Forecasting Center (BS-MFC).
