transition. Paleotidal changes seem to be recorded from the Atlantic coast of 

 France. The eustatic fluctuations correlate with fluctuations in 

 paleomagnetism and paleotemperature . This suggests a mutual origin. With the 

 theory of paleogeoid changes, we must solve each region within itself and 

 establish regional eustatic curves. The northwest European region provides 

 such a solution. When similar solutions are established from other parts of 

 the globe, the directions, amplitudes and the rates of the paleogeoid changes 

 can be measured. (Author) .

Eustasy is not a direct measure of the glacial volume changes during the 

 Late Cenozoic but largely the effect of paleogeoid changes. Neither are the 

 oceanic oxygen isotope records a direct measure of the glacial volume changes 

 and the glacial eustatic sea-level changes, instead they are also to a signi- 

 ficant degree influenced by paleogeoid changes over the globe. The Milanko- 

 vitch variables sensitively affected the Earth's geoid. This effect is con- 

 sidered to be the main reason for the correlation established between orbital 

 geometry changes and the oxygen isotope fluctuations in the deep sea records. 

 The insulation effects of the Milankovitch variables were therefore rather 

 modulating than controlling the Earth's climate during the Pleistocene.

Eustasy can no longer be defined as "worldwide simultaneous changes in 

 sea-level," but must be redefined as "ocean level changes" or any "absolute 

 sea- level changes" regardless of causation and including both the vertical and 

 horizontal changes of the geoid surface as well as changes of the dynamic sea 

 surface topography. In the field, we can only observe the "relative sea-level 

 changes . " (Author) .

The coastal plain and continental shelf of Texas were sites of 

 simultaneous erosion and deposition related to late Quaternary eustatic 

 fluctuations in sea-level. Geologic maps, deep borings, and seismic profiles 

 from the area provide evidence of how the dominant sedimentary processes 

 responded to changes in base level during the most recent (Sangamonian- 

 Holocene) depositional episode.
