Via the center of the 19th century, as scientists explored the frontiers of polar areas and the ambience, the sea remained silent and inaccessible. The historical past of the way this changed—of how the depths grew to become a systematic ardour and a cultural obsession, an engineering problem and a political attraction—is the tale that unfolds in Fathoming the sea.

1995) published a finite element, elastic, spherical shell model of crustal deformation in Alaska. The boundary conditions and constraints they imposed on the model were selected fault orientations and slip rates and baseline rates of change derived from VLBI observations at Nome, Fairbanks (Gilcreek), Sourdough, Alaska and Whitehorse, Canada. Many of the parameters of their model would probably be revised if the analysis were to be repeated today since contemporary geodetic observations (Fletcher and Freymueller, 1999; Fletcher, 2002; Fletcher and Freymueller, 2003), as well as new geological information, have provided a wealth of constraints not available to the earlier workers.

Although this conceptual decomposition has been applied to both elastic and viscoelastic models, it is particularly simple in the former case because there are analytical solutions for different types of dislocations embedded in an elastic half-space. The simple model is often made more sophisticated by considering complexities in the fault geometry, the finite thickness of the subducting and overriding plates, and strain accumulation and/or slip on subsidiary faults. Another method employed in modeling strain CRUSTAL DEFORMATION IN THE SOUTHCENTRAL ALASKA 47 accumulation between earthquakes is to mathematically lock the shallow portions of the plate interface together but allow for free slip below the locked patch.

Given these slow uplift rates, we may reasonably assume little or no postseismic uplift at Anchorage. In this case, the aforementioned relative uplifts are absolute. 37 m. There may have been transient motions, 30 COHEN AND FREYMUELLER particularly in the years immediately following the earthquake, that are not reflected in the long term averages. We will return to this issue briefly later. The time dependence of the uplift (Fig. 13) is another intriguing aspect of the leveling observations. Again taking Anchorage as a reference point, we find that the maximum uplift rate for the first year after the earthquake was 80– 90 mm/yr (150 – 160 mm/yr relative to Portage).
