coastDat Logo

The coastDat approach was developed to improve the observational data base and to increase data homogeneity and consistency.

The approach uses quasi-realistic numerical models of the marine atmosphere, tide-surges or wind waves to optimally exploit existing observations and to reconstruct the marine climate providing detailed hourly descriptions of changing marine environmental conditions from 1948/1958 up to now. Scenarios of potential future developments in a changing climate are also available, complementing the reconstruction of past conditions in a consistent way.

The coastDat approach was developed over more than 15 years and was successfully applied, for example, for providing assessments of the effectiveness of political measures to reduce chronic oil pollutions or changes in wind and storm surge climate. Industrial applications comprise, for example, uses in ship design, oil risk modelling and assessment, or the construction and operation of offshore wind farms.

The coastDat data set is used by more than 80 users with about 46 % of them located in industry, 15 % in authorities and 39 % in other research institutes.
