On Sunday we had gales and the sea was pouring on to the beach (Kennemerstrand, Ijmuiden) over the pier as well as the tide itself practically up to where the dunes start.
Sunday (22nd Jan) I noticed nothing, but a trip yesterday (23rd Jan), the sea had retreated 50 or more back to where you usually see it at it's high point. But along Sunday's tideline I saw blobs of oil at the north of the beach by the pier but as I started to walk further southwards the blobs were bigger and more of them.
The news last night reported that oil has been found from up the coast at Wijk aan zee, to Bloemendaal down the coast from here (we are in the middle).
Some oil covered sea birds have already been rescued and are being cleaned up.

I must see if I can find out who I should contact if I come across birds which have been covered in oil.
Oil samples have been taken, and the authorities involved are trying to to track down where the oil has come from.
On Friday a large ship had broken anchor a few km out at sea and was washed in to shore off of Wijk aan Zee and got stuck. I think this must be a coincidence and the ship would have been checked for damage at the time.
