The Australian Shellfish Reef Restoration Network is a recently established Community of Practice which brings together organisations and individuals interested in shellfish reef education, conservation, restoration and management. The Network aims to improve awareness of shellfish reef habitat and educate the broader public on the value of shellfish habitat conservation and restoration. The Network also promotes communication, restoration training, policy and regulation, research and development and implementation amongst network members. This record describes images collected by the Australian Shellfish Reef Restoration Network and freely available on https://shellfishreefs.smugmug.com/

This dataset displays the reefs and shoals within Queensland maritime waters. Names have been sourced from numerous locations and attributes within the data describe the source of the names. Name sources include but not limited to: - Queensland Place Names Database - Great Barrier Reef Base Mapping - Geoscience Australia 1:100000 Topographic Mapping

The data is quantitative abundance of fish and megafaunal invertebrates and algal % cover derived from transect based counts at a wide range of locations across Temperate Australia. The methods are described in detail in Edgar and Barrett (1997). Primarily the data are derived from transects at 5 m depth and/or 10 m depth at each site surveyed. Methods were initially developed for research on temporal changes following protection in Tasmanian MPAs (Maria Is, Tinderbox, Ninepin Point, Governor Island). The data represented by this record was collected in MPA studies and surveys interstate, and was collected from Jurien Bay (WA). In many cases the dataset involved temporal replication (year scale).

The spatial extent of C. rodgersii "barrens" was estimated by surveying rocky reef habitat with a towed underwater video system. Sampling took place at 13 regions along the east coast of Tasmania, each comprising 3 subsites, this dataset refers to the Schouten Island, and its 3 subsites: Baudin, Sarah and Sonerat.

The spatial extent of C. rodgersii "barrens" was estimated by surveying rocky reef habitat with a towed underwater video system. Sampling took place at 13 regions along the east coast of Tasmania, each comprising 3 subsites. Substrate and habitat type were recorded using video analysis, with 4 categories of urchin barren habitat recognised (see below for definitions).

Reef Life Survey is designed to develop and resource a network of skilled recreational divers for rapid and cost-effective assessment of the state of the inshore marine environment at the global scale. The project uses standardised underwater visual census methods employed by trained SCUBA divers to survey fish and invertebrate species and to record habitat type using photo quadrats - this particular dataset refers to the photo quadrats only. This data has been superseded by the NRMN collection "IMOS - National Reef Monitoring Network - Benthic cover data (in situ surveys)": see https://catalogue-imos.aodn.org.au/geonetwork/srv/eng/catalog.search#/metadata/ec424e4f-0f55-41a5-a3f2-726bc4541947
