All Ireland Survey (Autumn 2023)

Join Us

We would be delighted if you could join us in this annual citizen science shore survey, whether experienced surveyor or total new comer. 

It’s interesting, fun, energising and sometimes challenging and contributes enormously to our knowledge of the coastal rim. With climate change, new policies and laws this is a crucial time to have up to date information and thousands of eyes on the shore.
