  • The Aqua and Orbview satellites carry a MODIS and SeaWIFS sensors (respectively) that observes sunlight reflected from within the ocean surface layer at multiple wavelengths. These multi-spectral measurements are used to infer the concentration of chlorophyll-a (Chl-a), most typically due to phytoplankton, present in the water. There are multiple retrieval algorithms for estimating Chl-a and aggregating the data over time. This data set is a reprocessed copy of 9km monthly and 8-day versions produced globally by NASA, adjusted for the Southern Ocean south of latitude 30S. The full methodology is described in Johnson, R., Strutton, P.G., Wright, S.W., McMinn, A., Meiners, K.M., 2013. Three improved satellite chlorophyll algorithms for the Southern Ocean. Journal of Geophysical Research: Oceans. doi: 10.1002/jgrc.20270. It is expected that the data set will be periodically updated with contemporary data as it becomes available. There are four sub-streams within this data set. A monthly and an 8-day series for MODIS/Aqua and similarly for SeaWIFS. Note that SeaWIFS ceased operation in late 2010 so there will be no further SeaWIFS data. The data represented by this record is weekly data for MODIS/Aqua.

    This record presents data collected from tagged and recaptured Short-tailed shearwaters (Puffinus tenuirostris), with data presented throughout the Southern Ocean. The study was initially conducted on Wedge Island (43 km2), southern Tasmania (43o 07' S, 147o 40' E). Fifty geolocation archival (GLS) tag deployments were made on 34 adult birds in the pre-laying exodus (n = 18), incubation (n = 12) and early chick-rearing (ECR) phases (n = 20). In 2012, 12 birds were tracked during the pre-laying exodus. GLS tags were deployed between the 10th and the 18th of October. Ten birds were tracked from Wedge Island (as in 2010) and 2 were tracked from Whalebone Point, Bruny Island (43.44 South, 147.23 East; birds 22 and 80).

  • 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. Reef Life Survey (RLS) and 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 and RLS Advisory Committee. RLS and 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, RLS and ATRC aims to raise broader community awareness of the status of Australia?s marine biodiversity and associated conservation issues. This dataset provides the metadata associated with individual 50 m transects surveyed by Reef Life Survey (RLS) and Australian Reef Collaboration Network (ATRC) divers and partners. All surveys in this list were undertaken using standard methods. ATRC surveys are predominantly collected as a group of 4 x 50m transects per site, RLS surveys commonly have a minimum of 2 x 50 m surveys per site on any given date (typically at different depths), but this number often varies. This dataset supersedes the RLS specific "Reef Life Survey (RLS): Survey Locations " collection that was available at https://catalogue-rls.imas.utas.edu.au/geonetwork/srv/en/metadata.show?uuid=4972fa20-195b-41e4-bee8-8175d6ac792b (provision of data was stopped in June 2021).

By making data freely available and through public outputs, RLS and ATRC aims to raise broader community awareness of the status of Australia?s marine biodiversity and associated conservation issues. This dataset contains records of cryptobenthic fishes collected by RLS and ATRC divers and partners along 50m transects on shallow rocky and coral reefs using standard methods. Abundance information is available for all species recorded within quantitative survey limits (50 x 1 m swathes either side of the transect line, each distinguished as a 'Block'), with divers searching the reef surface (including cracks) carefully for hidden fishes. These observations are recorded concurrently with the macroinvertebrate observations and together make up the 'Method 2' component of the surveys. For this method, typically one 'Block' is completed per 50 m transect for the program ATRC and 2 blocks are completed for RLS ? although exceptions to this rule exist.

This dataset contains unstandardised occurrence records of bony fishes and elasmobranchs. They include any sightings of species by Reef Life Survey (RLS) and Australian Temperate Reef Collaboration (ATRC) divers and partners that were outside of the quanitative survey limits, but can be considered as occuring at that site on the date of the survey they are listed with.

This dataset shows the locations of Reef Life Survey (RLS) and Australian Reef Collaboration Network (ATRC) sites on shallow rocky and coral reefs, worldwide. Multiple transects (surveys) are usually surveyed within sites on any given date. Sites traditionally need a minimum of 200 m separation to be classified as a different site, unless separated by a significant geological feature or reef habitat discontinuity.
