Rockpooling destination: Hemsby, changing strandlines over winter months

The strandline at Hemsby has changed in composition over the last few months.
In November it was dominated by red seaweeds, by December the proportion of red seaweeds being washed up had decreased and by January 2015, the strandline was dominated by hornwrack with ever increasing numbers of  washed up ray and catshark eggcases.

The strandline is comprised of a variety of red seaweeds, the bryozoan, hornwrack (Flustra foliacea) and empty razor shells.

Erosion during a winter storm has caused a 'step' in the beach profile and removed the finer sediments whilst leaving the coarser sediments (pebbles and cobbles).

The shore has a relatively shallow profile which is dissected by a step caused by wave erosion.
