In this paper, Geosat altimetry data from the northeast Pacific are examined. The data are (1) binned data on 1¿ latitude by 2¿ longitude blocks and (2) collinear track data. The binned data cover the region from 20¿N to 60¿N from the North American coast westward to 150¿W and span from December 15, 1986, to June 1, 1989. To examine the data for evidence of westward propagation of sea level anomalies, three zonal transects (45¿N, 49¿N, and 57¿N) are made. Complex empirical orthogonal function analysis of the data transects at these latitudes reveals phase speed and amplitude information. The first eigenmode at each latitude has a very strong annual signal. Two-dimensional spectral analysis of the first eigenmode at 45¿N and 57¿N shows westward propagation of sea level anomalies at 45¿N only. The propagating features are annual in period and of order 1000 km in length. At 57¿N, westward propagation is evident (as at 45¿N), but there is also an eastward component. To examine the variability of the coastal sea level signal, collinear track data from three ascending tracks crossing the Gulf of Alaska are analyzed revealing mesoscale features of the order of 100 km that parallel the Canadian and Alaskan coast. The most notable feature is the Sitka eddy. Westward propagation of several of these features is observed. The results from the analysis of both types of Geosat data are compared with other observational data. ¿ American Geophysical Union 1992
