• Examining the evidence for a recent acceleration in the rate of sea level rise using combined instrumental and proxy data
Sea level rise is a potentially devastating consequence of climate change but multi-decadal records of sea level
change are severely lacking. Historical records of sea level change, such as tide gauge data and map evidence, are available
but generally lack the precision and detail required and cover only relatively short time spans. There is a need to combine
historical evidence with geological evidence to address this. Foraminifera are single celled protists which inhabit highly
constrained vertical distributions on salt marsh surfaces. Analysis of surface distributions can be compared to fossil data
using transfer functions and artificial neural networks with the resulting sea level reconstructions validated against the
historical records. The combined data will provide high resolution records of recent sea level changes and will be used to
calculate rates of sea level rise.
