Reef Life Survey is a marine life monitoring programme[1] based inHobart,Tasmania. It is international in scope, but predominantlyAustralian, as a large proportion of the volunteers are Australian. Most of the surveys are done by volunteerrecreational divers, collectingbiodiversity data formarine conservation. The database is available tomarine ecology researchers, and is used by severalmarine protected area managements in Australia,[2][3] New Zealand, American Samoa and the eastern Pacific.
Reef Life Survey provides data to improve biodiversity conservation and the sustainable management of marine resources. They collect and curate biodiversity information at spatial and temporal scales beyond those possible by most scientific dive teams which have to work with limited resources, by using volunteer recreational divers trained in the RLS survey procedures.[1][4] TheUniversity of Tasmania houses and manages the RLS database, and the data is freely available to the public for non-profit purposes through public outputs, including their website.
Reef Life Survey was started by researchers at the University of Tasmania and initially funded by theCommonwealth Environment Research Facilities (CERF) Program. This program is the core activity of the Reef Life Survey Foundation Incorporated – a not for profit Australian organisation.[1]
Reef Life Survey includes a volunteer network of recreationalscuba divers, trained in the relevant skills, and an Advisory Committee. The advisory committee is made up of managers and scientists who use the collected data, and representatives of the recreational diver network.[5]
Standard survey procedures are used matched to a variety of habitattopographies, and using simple equipment - waterproof clipboard with records sheet,underwater camera, and 50m surveyor's tape measure. The surveys are typically repeated at irregular intervals at listed sites, identified byGPS location,transect depth and direction, and are usually conducted as a pair of transects in opposite directions from the nominal position, at approximately constant depth. Data collected includes fish counts by visual census in a 5m x 5m corridor on both sides of the transect line (Method 1), mobileinvertebrate counts in a 1m corridor on both sides of the line (Method 2), and photo-quadrats at 2.5m intervals along the 50m transect line. Manufactured debris may also be recorded. Off transect observations of interest are recorded separately (Method 0). Numbers and size class are recorded for fish, just numbers for most invertebrates.[6]
Since 2006, divers have collected data for RLS from over 44 countries. As of September 2015, more than 4500 species have been recorded from over 7000 surveys.[citation needed]

During the voyage a marine baseline of reef biodiversity for the newCoral Sea Commonwealth Marine Reserve network was established.[7][8][9]
