Surveys of the coastal situation as regards erosion are normally carried out during each autumn and spring (erosion seasons) in order to capture change over summer and winter.
For more information see: data menu.
In the following table:
A: number of months between survey dates (the first is from March 2003);
B: total cliff loss in metres from monitoring profiles for the season as per published data sheets;
C: where intervals between surveys are shorter or longer than six months, an adjustment is made so that values are directly comparable.
No survey was conducted during autumn 2016 because of poor weather conditions. The cumulative total for that year is split 1:2 over the seasons.
