This paper is about establishing habitat suitability -- it relates abiotic information (e.g. seafloor maps) to biotic information.

We are exploring ways to use trawl data in conjunction with abiotic datasets to look at habitat modeling and assess habitat quality. I liked the data summary grids where fish density was plotted with abiotic variables. This gave me a clearer picture of what the thresholds really meant, and a general concept of the level of error associated with thresholds. This was more transparent than a habitat suitability score of 0 or 1.
