Were there any circumstances that influenced the survey?
There was large amounts of kelp and seaweed covering most of the beach surface, do to great waves and storms.
Were there any events that lead to unusual types and/or amounts of litter?
Little amount and different types of litter were found now compared to october 2017 survey. This is due to storms and great waves in December 2017 and January 2018. Most of the litter is likely under the seaweed/kelp, or washed out to sea by waves.
