GFAKSR89 Reconstructed surface elevation measured at Gullfaks C 24.12.1989. CALL: xn = load('gfaksr89.dat') Size : 39000 X 2 Sampling Rate : 2.5 Hz Device : EMI laser Source : STATOIL Format : ascii, c1: time c2: surface elevation Description : This is a reconstructed version of the data in the GFAKS89.DAT file. The following calls were made to reconstruct the data: inds = findoutliers(gfaks89,.02,2,1.23); gfaksr89 = reconstruct(gfaks89,inds,6); The wave data was measured 24th December 1989 at the Gullfaks C platform in the North Sea from 17.00 to 21.20. The period from 20.00 to 20.20 is missing in the original data. The water depth of 218 m is regarded as deep water for the most important wave components. There are two EMI laser sensors named 219 and 220. This data set is obtained from sensor 219, which is located in the Northwest corner approximately two platform leg diameters away from the closest leg. Thus the wave elevation is not expected to be significantly affected by diffraction effects for incoming waves in the western sector. The wind direction for this period is from the south. Some difficulties in calibration of the instruments have been reported resulting in several consecutive measured values being equal or almost equal in the observed data set. Hm0 = 6.8m, Tm02 = 8s, Tp = 10.5 See also gfaks89
