Coastal migration via satellite

Abstract

The shoreline is a highly dynamic land-sea interface that provides important services such as ecology, flood
protection and recreation. It is constantly modified by wind, waves and tides, and impacted by human activity.
Hence, the decadal change of shorelines reflect natural processes as well as human influence, whether positive
or negative. Climatic-driven changes such as sea level rise, higher waves and changes in wind direction put
increasing pressure on many of Europe’s shorelines.
Knowing how, and at what rate, our coasts are changing is the first step to successfully managing them. The
new EMODnet Geology shoreline-migration map, released today, allows users to visualise pan-European coastal
behaviour for 2007-2017 at different spatial scales. A built-in search and zoom functionality allows online users
to distinguish areas of landward migration (erosion or submergence), stability, and seaward migration (accretion
or emergence). The underlying, downloadable satellite-based dataset offers additional information on annual
values and uncertainty.
With the new map, international policy makers can determine large-scale coastal vulnerability while national
and regional coastal managers are able to fill existing gaps in field-monitoring data and to identify potential
areas of rapid change. The map also provides the general public with a useful insight into one of Europe’s most
obvious climate-change effects. Most importantly, scientists may explain spatial patterns and provide feedback
on methodological advantages as well as shortcomings, thus helping to optimise the big-data methodology
used.
