One problem all beaches have - litter.
Most beach litter accumulates on the strandline, which is also a good location for wildlife. Material provided in this area can be used to help understand what you are seeing.
The highest point the tide reaches on a beach is called the strandline. Here, the tides leave behind sediments such as seaweed, dead plants and animals and, unfortunately, litter. Several strandlines can occur on a beach due to changes in the height of the tides.
"Beachcombing" is the study of animals, or their remains, and other life washed up by the sea onto the beach strandline. Searching this strandline can be very rewarding. As well as clearing litter it's possible to find all kinds of other bits and pieces deposited there from further out to sea.
