Tracking: modeled large scale fish tracking (1)
The Australian Acoustic Tagging and Monitoring System (AATAMS) is a tool for observing large-scale movement of tagged marine animals. AATAMS is supported by the Integrated Marine Observing System (IMOS). It records the presence of animals as they pass through a cross-shelf array of receivers. A receiver network is currently being established along parts of the East, South and West coasts of Australia, and will be integrated with an internationally coordinated marine animal tracking program; the Ocean Tracking Network (OTN).
Arrays of acoustic 'listening stations' are becoming the world standard in marine animal tracking. These systems record the presence or absence of transmitters but do not record high-resolution animal positional information, so visualizing data has always been a challenge. For the first time, Eonfusion offers the ability to visualize short- and long-term temporal variation in the presence of tagged animals at receiver locations.
Eonfusion enables researchers to visualize frequency, abundance, and directional movement of tagged marine animals with time, as transmitters pass between receiver arrays. It also allows bathymetry and habitat data to be coupled with physical data such as sea surface temperature and current direction within one scene. Through the process of data fusion and visualization, researchers are able to detect patterns in species movement with oceanic events, and behavioral response to environmental variables. Seasonally triggered events, temperature-related regimes and oceanic current influence on migration can all be visualized using Eonfusion.
