Skjong, M.; Naess, A., and Brandrud Næss, O.E., 2013. Statistics of extreme sea levels for locations along the Norwegian coast. Journal of Coastal Research, 29(5), 1029–1048. Coconut Creek (Florida), ISSN 0749–0208.
The focus of this article is the problem of estimating long return-period sea levels for locations along the Norwegian coast. For this purpose, a new method for estimating the extreme-value statistics associated with a recorded time series of data is applied. This method, briefly referred to as the Average Conditional Exceedance Rate or ACER method, is presented in some detail. The ACER method provides a statistical representation with error bounds of the actual extreme-value distribution given by the data and is applicable to nonstationary time series as well. The estimated return-level values obtained by the ACER method are compared with the corresponding values obtained by the annual maxima method, the peaks-over-threshold method, and the revised joint-probabilities method. Based on overall performance, the ACER method may be the preferred choice over the other three methods tested.
