Investigations of historical sea-level changes in the Southern Hemisphere started in southern New Zealand in 2006, and now include additional sites in New Zealand, Tasmania and the Falkland Islands, with planned work in mainland Australia. The aim of these studies is to extend the short sea-level observational record in the Southern Hemisphere with salt-marsh based proxy reconstructions to test for geographical and temporal variability of recent sea-level accelerations. Over the years these studies have been funded by the Royal Society, various small travel grants and the NERC Radiocarbon Facility.
In most records the sea-level acceleration from the 19th to the 20th century appears to be faster than in Northern Hemisphere sites. This could point at northern hemisphere ice melt as the source of the acceleration.
