Full Title

2005 - Ongoing United Kingdom MarLIN Shore Thing timed search results


Intertidal species effort-based search undertaken by students (16+) and volunteer groups with support from an ecologist. During the twenty minute timed species search surveyors look for 22 species, 4 non native and 18 climate change indicator species within 1 of 3 habitats: rockpools; boulders, crevices and overhangs; or open rock. Abundance is recorded using a simplified version of SACFORN.


To generate records of marine wildlife by facilitating intertidal biological surveys at sites around the British Isles, and to make the results available to all on the Internet. In addition we aim to raise awareness of marine conservation amongst the participants and the wider community.

Quality control

Collected by students (16+) and volunteers under the supervision of rocky shore ecologists. Digitised data is verified and Quality Assured internally by scientists at the MBA.

Method Steps

  1. The surveys are conducted by students (16+) or volunteer groups with the aid of a trained rocky shore ecologist. The results are recorded using the following abundancy scale: Abundant = definitely found at a certain level of the shore, Frequent = definitely found after some searching, Rare = intensive search to find 1 or 2 individuals, and Not found = not found after searching (Abundant, Frequent and Rare results are recorded in the sample description). Species have been selected from the MarCLIM surveys and the Shore Thing protocol and recording forms are available on the project website. Data is submitted to NBN through Marine Recorder, but is recorded as presence/absence only through this pathway. Original records (AFRN) are kept in a MYSQL database at the Marine Biological Association and as hard copy in the same place.
