In my research, I am working to understand the sources and implications of uncertainty in marine habitat mapping. Marine habitat mapping is an established activity. However, perhaps because modern tools are so easy to apply, relatively little attention appears to be given to the original
measurements themselves. Without an understanding of the inherent uncertainty in the foundation measurements, any conclusions drawn from mapped habitats or changes in these may be overstated or simply incorrect. Additionally, maps are often treated as static phenomena, with minimal consideration of temporal and spatial processes. The creation of recommended protocols for marine researchers to follow when they are working on habitat and process mapping is much needed as the application of hydrographic measurements continues to proliferate. My research works to ensure that this very useful data is considered in the context of its suitability to the application, as well as investigating ways to improve methods that generate high-quality, repeatable scientific outcomes.
