We present a methodology for assisting with the citation of web service requests via provenance information recording and delivery. We decompose the representation of a web service request into endurant and occurant components, attempting to source as much information as possible about the endurant parts as organisations find these easiest to manage. We then collect references to those parts in an endurant `bundle', which we make available for citation.\\ Our methodology is demonstrated in action within the context of an operational government science agency, Geoscience Australia, that publishes many thousands of datasets with persistent identifiers and many hundreds of web services but has not, until now, provided citable identifiers for web service-generated dynamic data.

A fully four-dimensional (3D x time) object-oriented biophysical dispersal model was developed to simulate the movement of marine larvae over semi-continuous surfaces. The model is capable of handling massive numbers of simulated larvae, can accommodate diverse life history patterns and distributions of characteristics, and saves point-level information to a relational database management system.

PSMA Australia combines spatial data from Australia's governments to create national spatial information datasets that include features such as roads, street addresses, and cadastral and administrative boundaries. Geoscience Australia has entered into an agreement with PSMA Distribution Pty Ltd in June 2013 which provides GA access to key PSMA data products. The conditions of use are stipulated in the End User Agreement (EUA) and simplified form of Terms and Conditions (see below) will be made available soon to GA staff. The EUA has been extended in December 2013 to include the Land Tenure and Postcode Boundaries datasets, effectively providing GA access to the whole suite of PSMA products. These are: -Administrative Boundaries -Features of Interest -CadLite -Geocoded National Address File (G-NAF) -Land Tenure -Postcode Boundaries -Transport & Topography For more details about these products - including content and maintenance cycle - please refer to PSMA website (http://www.psma.com.au/list-products/).

As part of the Australian Tsunami Warning System Project (2005-09), the Attorney-General's Department funded Geoscience Australia to develop the national offshore Probabilistic Tsunami Hazard Assessment (PTHA). This assessment could then be used by Australian emergency managers in understanding the tsunami hazard to Australia. The national offshore PTHA considers the tsunami hazard posed to the entire Australian coast by tsunami caused by subduction zone earthquakes in the Indian and Pacific Oceans. These regions are known to have produced major tsunamigenic events External site link in recorded history and are the most likely sources of future events. The hazard maps are defined at a bathymetry water depth contour of 100m offshore. This normally falls outside of the Great Barrier Reef or other reef systems. The 100m depth contour is chosen because: Estimating the tsunami closer to the coast requires high resolution bathymetric data which does not always exist for the entire coast estimating the tsunami closer to the coast is a more computational and time intensive task. These maps help to identify the areas which are most likely to be at risk to damaging tsunami waves. However, they cannot be used directly to infer how far a tsunami will inundate onshore (inundation extent), how high above sea level they will reach on land (run-up), the extent of damage or any other onshore phenomena. To estimate the onshore tsunami impact, detailed bathymetry and topography of the specific region concerned is required for input to a detailed inundation model. The catalogue of tsunami events used to derive the national offshore PTHA can be used by emergency managers, researchers and individuals however to develop detailed inundation models at any onshore location.
