During the big seas in April, particularly those on April 15, large amounts of kelp were torn up and cast ashore. Below the surface there will have been a lot of movement of sand, gravel and small boulders, possibly even very large boulders. Once we're out of lock down and allowed to dive again it would be interesting to see if there are any visible signs of this disturbance and potentially document the recovery. It will also be interesting to see what has happened to the piles of seaweed on shore (https://www.inaturalist.org/observations/43028575) and record some of the species that have colonised them.
