Modelling sea level data from China and Malay-Thailand to estimate Holocene ice-volume equivalent sea level change

Estimating past continental ice volume from sea-level data

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...

Ice sheets and sea level.

Ice-sheet contributions to future sea-level change.

Accurate simulation of ice-sheet surface mass balance requires higher spatial resolution than is afforded by typical atmosphere-ocean general circulation models (AOGCMs), owing, in particular, to the need to resolve the narrow and steep margins where the majority of precipitation and ablation occurs. We have developed a method for calculating mass-balance changes by combining ice-sheet average ...

Sea level and global ice volumes from the Last Glacial Maximum to the Holocene.

The major cause of sea-level change during ice ages is the exchange of water between ice and ocean and the planet's dynamic response to the changing surface load. Inversion of ∼1,000 observations for the past 35,000 y from localities far from former ice margins has provided new constraints on the fluctuation of ice volume in this interval. Key results are: (i) a rapid final fall in global sea l...

Minimal late Holocene sea level rise in the Chukchi Sea: arctic insensitivity to global change?

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...
