Results and Applications

The contoured sensor data is typically presented as shiptrack distance in Port Phillip Bay and Bass Strait against date.  For example a six month plot represents data from ~180 Bass Strait crossings, with 10 second records representing a 100m average that accumulates to over 4400 “samples” per crossing. Figure 1 shows dynamics of PPB and adjacent Bass Strait waters. Figure 2 shows the conditions in 2008 and 2009 for the entire ship track. The vast dataset is being used to quantify satellite images, interpolate traditional monthly site-specific sampling and integrate into operational models to assess system responses (e.g. plankton blooms, dredging, oils spills, fish kills, climate change).
