[PDF][PDF] Gravity Anomalies from Retracked ERS and Geosat Altimetry over the Great Lakes: Accuracy Assessment and Problems.
Lake waters are a useful area for investigating the response of the Earth's gravity field to
topographical density variations, since lake beds represent large density contrasts between
water and rock. However, our ability to investigate relations between lake bathymetry and
gravity field effects is limited because of relatively sparse gravity data coverage over most
lake surfaces, and the inability of satellite-derived gravity fields to capture the high frequency
response to density effects. Satellite altimetry may provide an alternate method to determine …
