This study addresses the impact of satellite altimetry data processing on sea level studies at regional scale, with emphasis on the influence of various geophysical corrections and satellite orbit on the structure of the derived interannual signal and sea level trend. The work focuses on the analysis of TOPEX data for a period of over twelve years, for three regions in the North Atlantic: Tropi...

Remote sensing data and Geographic information systems (GIS) are relatively new and potentially valuable tools for coastal zone management. This paper examines the effectiveness of using remote sensing data to detect sea level change. Since resolution is such an important and vital element of spatial digital data for use in geographic information systems, it is important to know how to assess i...

Long-term estimates of sea level rise are essential for planning responses to anthropogenic global change. The tectonically stable, unglaciated eastern Chukchi Sea coast has numerous depositional environments for extracting long-term records in the absence of tide gauge data. Radiocarbon ages (n= 27) on paleo-marsh beds along several Seward Peninsula lagoons allows the reconstruction of sea lev...

Currently regional mean sea level trends and variations are inferred from the analysis of several individual local tide gauge data that span only a long period of time at a given region. In this study, we propose using amodel to merge various tide gauge data, regardless of their time span, in a single solution, to estimate parameters representative of regional mean sea level trends. The propose...

The prediction of global sea-level rise is one of the major challenges of climate science. While process-based models are still being improved to capture the complexity of the processes involved, semi-empirical models, exploiting the observed connection between global-mean sea level and global temperature and calibrated with data, have been developed as a complementary approach. Here we investi...

We predict sea-level change since the Last Glacial Maximum (LGM) at four far-field sites (Barbados, Bonaparte Gulf, Huon Peninsula and Tahiti) using a revised theoretical formalism. This formalism includes a time-varying shoreline geometry, an accurate treatment of sea-level variations near regions of ice retreat and the influence of glacial cycle perturbations in Earth rotation. We elucidate t...
