Recent increase in data collections harvested through to the AODN Portal from the Institute for Marine and Antarctic Studies (IMAS)
Increase in IMAS data collections in the AODN Portal
We recently reported that users are now able to download data in the form of shapefiles - see story here. The Institute for Marine and Antarctic Studies (IMAS) at the University of Tasmania (one of the first adopters of the AODN portal stack) has taken advantage of this new feature and have configured many of their metadata records to accommodate this new feature. This has had a flow on effect, with a dramatic increase in the number of data collections being suitable for harvest into the AODN - in January we had 9 collections coming from IMAS, and this has now increased to over 40.
The majority of these new additions form part of the Seamap Australia project, which has collated all known marine benthic habitat mapping data from across Australia as part of trialling a new seafloor habitat classification scheme. As part of the project, the original data in its native form will be displayed through the Seamap Australia website along with the reclassified national mapping product. IMAS is hosting the data on behalf of all the contributing parties, and has created metadata records to describe these data layers. The layers will continue to grow as IMAS produce new metadata records to describe this resource.
Other notable IMAS data collections discoverable through the AODN Portal:
- Nearshore temperature monitoring in Tasmanian coastal waters - an ongoing IMAS high-resolution data collection of in situ water temperature from loggers at 27 sites around Tasmania.
- Redmap - Sightings of range shifting marine species - a national citizen science program that utilises scientist-validated sightings made by the public of range-extending marine species. The data is live but is currently subject to a three year embargo (i.e. does not contain data less than three years old) and the data's spatial resolution is reduced for distribution purposes to protect sensitive fishing areas.
- Condition of rocky reef communities around Tasmania: invertebrate surveys + Condition of rocky reef communities around Tasmania: algal surveys + Condition of rocky reef communities around Tasmania: fish surveys - a comprehensive diver-collected survey dataset of nearshore reef biota from 136 sites spanning 8 bioregions around Tasmania. Initial surveys conducted between 1992-1995 and again 2006-2007. A highly valuable baseline dataset for monitoring of climate effects / anthropogenic pressures etc.
- Reef Life Survey (RLS): Global fish dataset + Reef Life Survey (RLS): Invertebrates + Reef Life Survey (RLS) Habitat Quadrats + Reef Life Survey (RLS): Cryptic Fish - these are large-scale datasets generated by a network of recreational divers all over the world, providing a framework for monitoring the state of the inshore environment and the identification of those threats and locations of greatest conservation concern.
