Contains the model output from Spadyno, a benthic habitat modelling and display package developed for the NWSJEMS project. The model predicts benthic habitat recovery under various fishing regimes. Two different modelling approaches can be selected by the user. The software also allows the user to vary environmental parameters such as cyclone activity and currents. Accompanying the model output on the production CD is source code, input data and documentation. The model is written in C and the output is in Visual Basic.

The Connectivity Interface or "ConnIe" has been developed as a tool for environmental scientists and managers to investigate the patterns of spatial connectivity on Australia's North West Shelf (NWS). Specifically, it provides the user with an estimate of the probability that any two regions are connected by modelled ocean circulation over a specified dispersion period. These connectivity statistics were computed from the paths of neutrally buoyant particles computed from the "Northwest" circulation model (based on MECO), run over the period from 1994 to 1999. The circulation model used a rotated latitude-longitude grid, with a horizontal resolution of approximately 10km and a vertical resolution expanding from 3 m near the surface to a maximum of 200 m at depths below 1000 m. The model was forced by wind fields from the NCEP-NCAR Reanalysis, while temperature and salinity fields around the lateral boundaries were interpolated from a global circulation model known as the Australian Community Ocean Model (ACOM). Sea levels on the boundaries were also taken from the global model output, with the addition of a tidal component derived from a combination of coastal sea level data and output from a global tidal model. ConnIe is expected to find applications in areas such as larval dispersion and recruitment studies, and the development of scenarios and risk assessments for contaminant dispersion.

The dataset comprises output from a circulation model of the NWS based on the three-dimensional non-linear hydrodynamic model referred to as MECO. The model spans the Pilbara coast (Ningaloo to Port Hedland) with a horizontal resolution of approximately 5km and vertical resolution expanding from 3 m near the surface to a maximum of 200m at depths below 1000m. Outputs cover the period from August 1996 to May 1998 with hourly outputs of sealevel, surface temperature, surface salinity, surface currents, depth-averaged currents, and bottom friction velocity, as well as 5 day outputs of the full 3-dimensional fields of temperature, salinity, and velocity.

The data was summarised to produce an interim report to describe the trawling effort and total catch in the North West Shelf of Australia between 1973 and 1997. It contains foreign and domestic commercial fisheries data from three separate sources: Taiwanese Logbook data (Anon. 1973-1982), foreign (Taiwanese, Chinese and South Korean) trawl data collated by the Australian Fisheries Management Authority (1979-1989), and domestic catch and effort statistics data collated by Fisheries, Western Australia (1979-1997). Trawling effort and total catch by year, as well as catches of 22 species categories (mostly family level classifications) are sumarised spatially into a 10x10 minute grid scale over part of the NWS region to show spatial distribution. The original Report produced Mar 2001 was updated and corrected in 2003.<br> The corrections made are: (1) the Taiwaneses total catch was recalculated using all categories reported in the Annual reports (previously invertebrates, 'dumped' and 'other' were excluded); (2)Taiwanese effort data was corrected for logbook recovery rates reported in the Annual Reports.<br> The update refers to an additional section describing the data that was used in NWS-JEMS Project 5.
