Unlike Chesapeake Bay, Pamlico Sound is a lagoon, which means it’s wide, shallow, mostly water, and connected to the ocean via fairly small inlets between barrier islands. We used boosted regression tree modeling to figure out the preferred environmental ranges for each of the six principal species, which we then used to generate maps that predicted the likelihood of encountering each species across the estuary. Photo from the Smithsonian Environmental Research Center. Drone footage from Corolla, North Carolina on the Outer Banks shows sharks swimming in a bait ball and around unknowing swimmers.

Because there can be a lot of variability each time you run an individual tree model, the “boosted” part comes from the stats software replicating the trees hundreds to thousands of times, getting a little better at it each time, until it comes up with the combination of environmental ranges with the least potential to give you a weird result. The tagged shark only “pings” when it surfaces, and has covered 179 miles in the last 72 hours, so for all we know, the fish may have swam up the river????

Four of the six species (Sharpnose, Blacktip, Sandbar, and Spiny Dogfish) showed a pattern I like to call “inlet hugging,” which is defined by a preference for higher salinities and closer proximities to the inlets.

The mine itself is an open-pit phosphate mine on the south shore of the Pamlico River which exposes: Pungo River Marl (Lower Miocene), Yorktown ( Early Pliocene), Chowan River (Late Pliocene) and James City (Pleistocene) Formations.
