for a relative fall of sea-level comes from coastlines well removed from areas 

 of rebound and which have been affected by a rise of the continental areas 

 through compensation for the eustatic load. It is concluded: (1) no sub- 

 stantial eustatic change of sea- level in the past 6,000 years is required to 

 explain postglacial sea-levels: (2) in the late glacial time the eustatic 

 curve is probably more like the sea- level curve of Texas and Mexico than that 

 of the Atlantic seaboard of the United States: (3) that the information of 

 past sea-levels, when sufficiently widespread, can provide an important method 

 of studying the deep mechanical structure of the earth. (Author) .

 Annual Maximum Sea-Levels Using Robust Locally Weighted Regression," 

 Estuarine. Coastal, and Shelf Science . Vol 16, pp 17-26. 



Estimates of the frequency of occurrence of extreme high sea-levels may 

 be obtained from a sample of annual maxima. However, the presence of a 

 secular trend may lead to serious doubts about the validity of analyzing these 

 annual maxima as if they were a random sample from an extreme -value distribu- 

 tion. Robust locally weighted regression, employing a simple model, is used 

 to illustrate how any secular trend may be estimated. The annual maxima may 

 then be adjusted for this trend and more reliable estimates of the frequencies 

 of occurrence of extreme sea- levels determined. (Authors) .

 Currents in South San Francisco Bay," Journal of Physical Oceanography . Vol 

 12, pp 658-668. 



In order to examine physical processes in the subtidal time range, 

 sea- level and current m data for south San Francisco Bay (South Bay) were 

 filtered using a low pass digital filter to remove tidal period variations, 

 and then subjected to an empirical orthogonal function analysis. For the 

 sea- level data, there is one dominant empirical mode that is correlated with 

 nonlocal coastal forcing. A small amount of the variance is associated with 

 local wind setup. For the current data, there are two dominant empirical 

 models that correlate with local wind forcing and tidal forcing over the 

 spring-neap cycle. In general, South Bay is dominated by coastal forcing on 

 sea- level during all seasons, and dominated by wind and tidal forcing on the 

 residual currents during the summer. (Author).

 Atlantic Bight," Journal of Marine Research . Vol 37, No. 4, pp 683-697. 



Low- frequency sea- level fluctuations on the Mid-Atlantic Bight, from 

 Cape Cod to Cape Hatteras, and their relations to wind forcing were examined 

 over a one-year (1975) period. The dominant sea-level fluctuations occurred 

 at time scales of 4 days, and they were coherent over the entire Bight. On
