A map I created in ArcGIS to show different traffic volume intensities and fish distribution networks throughout the Clearwater Basin. Using data layers published through ArcGIS Online, I downloaded fish distribution data from IDFG, traffic data (average annual daily traffic) from Idaho Department of Transportation, and clipped these two layers to the Clearwater Basin layer I downloaded from USGS.

I created this map to show fish habitat that is within 200m from a primary road in the Clearwater Basin. I used the same fish distribution data from the map above and downloaded the primary road layer as a shapefile from TIGER/Line. After clipping these layers to the Clearwater Basin, I used the pairwise buffer tool on the road layer and used this as my buffer for the fish distribution layer.

Tire particles are notoriously difficult to separate from environmental media (i.e. sediment) and quantify, compared to other types of microplastics. The photo on the left shows the stage of a microscope with light penetrating up through a filter paper that has been prepared with tire particles. The photo on the right is what we can see when we look through the lens of the microscope.

Photos of me presenting the poster I created for the 2023 Fall American Geophysical Union conference. The maps I created reflect a simplified approach for predicting hotspot tire pollution by overlaying predictor variables and factoring the weight of influence for each layer.
