The surveys are conducted by A-level students or volunteer groups with the aid of a trained rocky shore ecologist. The results are recroded using the following abundancy scale: (1) Abundant = definately found at a certain level of the shore, (2) Frequent = definitely found after some searching, (3) Rare = intensive search to find 1 or 2 individuals, and (4) Not found = not found after searching (Abundant, frequent and rare results recorded in 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 sumbitted 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.
