A collection of marine life surveys collated by the Marine Life Information Network (MarLIN) as part of their data access program. Surveys are either flagged as professional surveys or data collected by volunteer recorders as part for the Sealife Survey. Information about survey methodology can be found on the MarLIN Web site (www.marlin.ac.uk). There are currently 368 surveys collated by MarLIN containing 250,000 species records. Data ownership remains with the data provider and permission must be sought for commercial use of the data.

Recording Invasive Species Counts (RISC) alongside ALERT was launched in 2010 and includes on-line recording for 19 species including the Chinese Mitten Crab <i>Eriocheir sinensis</i>, Wakame <i>Undaria pinnatifida</i> and Carpet Sea Squirt <i>Didemnum vexillum</i>.

The SAHFOS CPR survey is the longest and most geographically extensive marine biological survey in the world. The CPR survey has been in operation in the North Sea and North Atlantic since 1946 and has systematically sampled up to 500 planktonic taxa from the major regions of the North Atlantic at a monthly resolution. This dataset contains also CPR surveys in the Pacific and the South Atlantic.

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.
