The Auslig 250k series 1 Topograpic data (Geoscience Australia 2000) was used along with a North West Shelf coastline contour to generate a 0.008 degree grid using the ArcInfo topogrid command. This was merged with the AGSO bathymetric 30 second grid (Geoscience Australia) to form a complete bathymetric and topographic grid at 0.008 degree resolution for the complete North West Shelf study area. Finally this grid was projected to a Lambert Conformal Conic projection for use by the model. Conformal projections, ensure that scale is invariant in all directions locally, but large grids/areas will be distorted because of differential 'stretching' of areas across large scales.

This is a historical data set containing a recored of all types of fish caught in the Pilbara region of the Australian Northwest shelf since the 1960's. The data was source from both domestic and foreign fishers. It was transcribed from the fishers paper logbooks and contains catch (type, weight, date, location) and effort (number of boat days).

The data-rich screens of the NWS Technical User Interface mainly serve for analysis of raw inputs into InVitro, the spatially explicit agent-based biophysical simulation model at the core of this Study. The software is written in Java.

This Ecopath with Ecosim (EwE) model was developed for the North West Shelf and the food web upon which it is based. The fishery of the area has been variable over the years. Bulman attempts to capture the trophic flows and biomasses during the late 1980s. At this time, the foreign fishery had reduced considerably following closures and the domestic fisheries were expanding. Fifteen years of catch and effort data were used to tune the model, i.e., annual fishing effort data were input in order to try to recreate the actual changes in the system caused by fishing.

This group of files are the configuration files used in the NWSJEMS MSE runs. A start or end time of 0 indicates that the agent will commence (or end) with the entire simulation rather than on a specific date. The configuration parameters typically include the latitude and longitude of their starting position or extent, whether they are to be tracked, their periodicity of output and a sting list of other agent types they may be interested in.
-
This group of links are the input data used in the NWSJEMS MSE runs. This metadata record contains the links to all the metadata records for the input data. Access to input data for InVitro is controlled through the input data source.
-
Official NWSJEMS Study Area boundary. Bounding box extends from west of North West Cape to Port Hedland. This study area boundary is based on the extent of data used for modelling purposes.
-
This Access database contains the NWSJEMS Contaminants Inventory of data from 1985 to 2001. Spatial information is contained in related shapefile datasets described in Marlin (see Attributes)
-
The NWSJEMS Contaminants Inventory contains primary contaminant load data: polygon data shows spatial location of outflows to the marine environment and time series of contaminant shows loads and species of contaminant.
