This record describes the WAMSI KMRP Project 2.2.8: Knowledge Integration and Management Strategy Evaluation (MSE) Modelling of the Kimberley Region. The project explores the possible and desired futures of the Kimberley region using two computer models, Ecopath with Ecosim (EwE) and ALCES. In this project the future is defined to 2050. EwE was used to characterise the trophic structure, ecosystem attributes and impact of fishing and climate change in the region. ALCES modelled terrestrial land-use and landscape dynamics and interfaced with the marine ecosystem dynamics (EwE) model to generate output on how these ecosystems interact and change over time. The purpose of using these models was to integrate existing and new knowledge about the Kimberley system and to provide an estimation of the likely impacts of different stressors on the land (ALCES) and marine (EwE) environments. This metadata record relates to the input and outputs for EwE and lists only the inputs form ALCES. Refer to the additional metadata description for details on the ALCES component.
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.
Data collection was in a seasonal (HES Surveys)and a weekly/fortnightly (CM Surveys) regime. Water quality and trace metal data were collected during the August/September 1998 Contaminants Survey (HES10A). This record references the hydrology, nutrients and water quality data for the Huon Estuary Study. This includes nitrite, nitrate, total dissolved nitrogen, total nitrogen, phosphate, total dissolved nitrogen, silicate, salinity, dissolved oxygen, ammonia, suspended solid and trace metal data. The final data for these data parameters has been loaded into the project database (and subsequently the oracle database) see Marlin record 'Huon Estuary Study-Database'. However, these final datasets along with any intermediate files have also been written to cdrom as text files for archiving purposes by the Data Centre, Hobart. Methods documentation has also been written to the archive cdrom. The completed Field Sheets for all surveys have been stored by the Data Centre-Hobart.
