Both maps show bottlenose dolphin modeled density. The right map overlays survey tracklines and animal sightings, so that correspondence between the model predictions and raw survey data may be assessed visually. The abundance plot (heavy black line) shows the total number of animals present in the modeled area throughout the year. The red line tracks the date of the animation. Note: These daily images are for illustration only. For management applications, we recommend the monthly maps shown below. (Credit: Duke Marine Geospatial Ecology Lab)
