Collection of marine life surveys collated by the Marine Life Information Network (MarLIN) as part of their data access program.

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.

Accredited through the MEDIN partnership, and core-funded by the Department for the Environment, Food and Rural Affairs (Defra) and the Scottish Government, DASSH provides tools and services for the long-term curation, management and publication of marine species and habitats data, within the UK and internationally.

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 data is predominantly provided by members of the public but records are verified from photos by designated experts. No additional attribute data is included for the Carpet Sea Squirt. The recording forms for Chinese Mitten Crab and Wakame includes the option to provide abundance. Additionally for the Chinese Mitten Crab information on whether it is dead or alive is recorded and for Wakame attachment method (attached to boat, attached to other man-made surface, attach to natural surface or detached) is recorded.

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.

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.

This dataset provides information on the species composition and abundance of North Sea meiobenthic nematode assemblages

75 samples collected with a NIOZ core in 2001, in the Scottish waters.

This dataset represents a subset of data collected from offshore locations around England and Wales under the auspices of the National Marine Monitoring Programme (NMMP).
