As an island nation comprising 60,000 km of open coastline and extensive margins of increasingly urbanised inter-tidal estuarine foreshores, Australia is critically exposed to the global threat posed by rising sea levels into the future.
Hosted by NSW Coastal Ocean and Port Engineering Panel (COPEP) and National Committee on Coastal and Ocean Engineering (NCCOE), this webinar will highlighting key emerging trends around the country, based on research undertaken to provide an updated, contemporary assessment of sea level rise around Australia to the end of 2018, based on all available tide gauge records and satellite altimetry.
The research also provides the first national assessment of vertical land motions (VLM) around the coast, identifying margins more prevalent to subsidence, which in turn exacerbate the localised effects of a rising global mean sea level.
Speaker Dr Phil Watson will also discuss a range of scientific and analytical advancements which have been developed over recent years specifically for sea level research. These advancements have enabled improved insights into the temporal resolution of current rates of sea level rise and associated accelerations compared to what was previously possible from long tide gauge records. Australia has several high-quality, long records available around the coastline that are suitable for application of these improved sea level and time series analysis techniques.
Dr Phil Watson: Honorary Research Fellow, US Coastal Education and Research Foundation and Principal Coastal Specialist, NSW Department of Planning, Industry and Environment
In February 2018, Phil graduated from University of NSW with a PhD studying Improved techniques to estimate mean sea level, velocity and acceleration from long ocean water level time series to augment sea level (and climate change) research. In his capacity as an honorary research fellow, Phil has published several scientific research articles covering areas including vertical land motions, regional sea level rise, satellite altimetry and climate projection modelling. Phil was an expert reviewer for the IPCC’s Fifth Assessment Report (2013) and recent Special Report on the Oceans and Cryosphere (2019).
