Abundance information is available for all records found within quantitative survey limits (50 x 5 m swathes during a single swim either side of the transect line, each distinguished as a Block), and out-of-survey records are identified as presence-only (Method 0). Although surveys are undertaken as part of monitoring programs at particular locations (mostly in Australia), this dataset contains does not include repeat surveys of sites.

Reef Life Survey is a program that trains and assists a network of skilled and committed recreational divers to cost-effectively assess the state of the inshore marine environment at the continental scale. The program uses standardised underwater visual census methods employed by SCUBA divers to survey fish and invertebrate species and to record macroalgal and coral cover using photo quadrats - this record refers to the website for this program. By standardising techniques and establishing a monitoring system on a nation-wide scale, the program addresses many of the current problems associated with managing the marine environment, including the paucity, patchiness and variable quality of data on the distribution of and trends to marine biodiversity. A central database is managed for the storage, analysis and dissemination of data collected nationally, with a publicly-accessible web-based portal. The website allows information collected on Australia's marine environment to be accessed in a meaningful form by policy-makers and the general public, including recreational groups, scientists and industry. It also has information and resources for particpating divers and those wishing to become involved. The dataset generated by recreational divers will provide a national framework for monitoring the state of the inshore environment and the identification of those threats and locations of greatest conservation concern.

eDNA metabarcoding were applied using the rRNA 18S Universal eukaryote assay to explore differences in community profiles between samples collected from the lagoon and reef slope habitats across the Ningaloo Coast World Heritage Area in Western Australia In May 2019, near-surface (1–2 m depth) 120 seawater samples were collected at 14 different localities along Ningaloo Reef, from the backreef lagoon and the exposed reef slope. For shallow lagoon samples, five replicate 1 L samples were collected at five different sites across the reef using Nalgene bottles by snorkellers (site depth < 6 m). At each site, three different locations were used for the replicates, within a 5 m radius of each other (n = 75 samples total, 15 samples per lagoon site). On the reef slope, samples were collected using a livewire CTD Niskin rosette system, with five replicates repeated at nine sites approximately ~ 20 km apart along the western edge of the outer reef at a site depth range of 11 to 22 m (n = 45 samples total). All samples were filtered, and DNA extraction occurred. 2061 amplicon sequence variants were recovered that comprised of 401 taxa spanning 14 different metazoan phyla such as cnidarians, poriferans, molluscs, algae, worms, and echinoderms.
