Since its launch in 1998, Coastalwatch has become Australia's most popular water sports website, and is consistently ranked in the top eight sporting websites. The site displays live vision from over 90 coastal locations around Australia and overseas. It also provides daily surf reports, swell forecasting, weather information and news; as well as video, photographic and editorial content. Coastalwatch has also developed a Coastal Conditions Monitoring System, which utilises the camera network to make a significant contribution to safer coastal use and more efficient and cost effective coastal management. To this end, Coastalwatch has partnered with Surf Life Saving Australia and Surfing Australia; and supports Volunteer Rescue organisations, community groups, and charities such as SurfAid International and the Surfrider Foundation Australia. Coastalwatch is committed to bringing the coast to all Australians and overseas visitors, and becoming the premier reference site for all coastal user groups. With this in mind, Coastalwatch is dedicated to assisting with sound coastal zone research and management through the use of all its resources.

The National Reef Monitoring Network brings together shallow reef surveys conducted around Australia into a centralised database. The IMOS National Reef Monitoring Network sub-Facility collates, cleans, stores and makes this data rapidly available from contributors including: Reef Life Survey, Parks Australia, Department of Biodiversity, Conservation and Attractions (Western Australia), Department of Environment, Water and Natural Resources (South Australia), Department of Primary Industries (New South Wales), Tasmanian Parks and Wildlife Service and Parks Victoria. The data provided by the National Reef Monitoring Network contributes to establishing and supporting national marine baselines, and assisting with the management of Commonwealth and State marine reserves. The Australian Temperate Reef Network (ATRC) aims to improve biodiversity conservation and the sustainable management of marine resources by coordinating surveys of rocky and coral reefs using scientific methods, with the ultimate goal to improve coastal stewardship. Our activities depend on the skills of marine scientists, experienced and motivated recreational SCUBA divers, partnerships with management agencies and university researchers, and active input from the ATRC partners. ATRC data are freely available to the public for non-profit purposes, so not only managers, but also groups such as local dive clubs or schools may use these data to look at changes over time in their own local reefs. By making data freely available and through public outputs, ATRC aims to raise broader community awareness of the status of Australia?s marine biodiversity and associated conservation issues. This dataset contains data on the cover of macroalage and sessile invertebrates collected in situ at Australian Temperate Reef Collaboration (ATRC) sites. Quadrats are placed at 10 m spacing along each transect line (i.e. 5 per 50 m transect and 20 per contiguous 200 m) by divers skilled in macroalgal identification. The canopy layer, mid-story and substrate are sequentially assessed in each single, 50 -point quadrat.

An oceanographic pilot study was carried out at Scott Reef to investigate the behaviour of surface and internal waves in the vicinity of an isolated coral reef. Oceanographic instruments deployed included 4 pressure gauges on the reef edge and 2 current meter arrays extending across the reef slope. 64% of possible data was recovered from the 25 instruments deployed. 4 instruments were lost or stolen, 2 instruments leaked and 3 instruments did not perform to specifications. CTD data was also collected.

The AADC (Australian Antarctic Data Centre) is in the process of converting all internally held spatial datasets to the ITRF2000 horizontal datum. This consolidated dataset consists of surveys HI623_alatB_gg, HI625_alatB_GG, HI632_alat_B_gg, HI632_alat_C_gg, LADSII_MMI20756_HSDB_T0001_SD_100029052_op, LADSII_MMI20756_HSDB_T0001_SD_100029053_op, LADSII_MMI20756_HSDB_T0001_SD_100029054_op converted to ITRF2000 horizontal datum with Z conversion values for multiple height datums. The data was provided to the AAD by Paul Digney of Jacobs consulting in March 2021. Included survey datasets: • HI623_alatB_gg • HI625_alatB_GG • HI632_alat_B_gg • HI632_alat_C_gg • LADSII_MMI20756_HSDB_T0001_SD_100029052_op • LADSII_MMI20756_HSDB_T0001_SD_100029053_op • LADSII_MMI20756_HSDB_T0001_SD_100029054_op All data are in horizontal datum ITRF2000 and have been combined into a single ESRI geodatabase feature class titled AHS_Surveys_Macca_ITRF2000. Attribute data shows quality information, conversion factors (shift in metres) for multiple datums and the MSL orthometric height: Column Name Alias Meaning Easting Easting Easting ITRF2000 Northing Northing Northing ITRF2000 LAT_to_GRS LAT_to_GRS LAT (Chart Datum) to GSR80 LAT_to_Mac LAT_to_Mac LAT to Macca MSL Z_To_GRS80 Z_To_GRS80 Height to the Ellipsoid Z_To_Macca Z_To_Macca Local MSL orthometric height Vertical_U Vertical_U How good is the Vertical Position Horizontal Horizontal How good is the Horizontal Position Uncertaint Uncertaint Uncertainty Comments Depth_Comm Depth_Comments Vertical uncertainty ranges from 0.5 to 1.2 m and horizontal uncertainty ranges from 2 to 5.5 m.
