Sampling Trawl aboard a Research Vessel
Part of being a researcher is conducting sampling expeditions, and the moment we step on board the research vessel we will transform into marine scientists. Our sampling trip will take us from the heart of Wilmington and down the Cape Fear River toward the mouth, where we will sample, identify, and classify numerous species of vertebrates and invertebrates that we collect during a trawl of this soft, muddy bottom habitat.
While the downtown area is located about 20 miles from the river mouth, there is a strong salt water influence. Decades of dredging have substantially changed the habitat, so that it is now characterized as brackish. This provides a habitat overlap for marine and freshwater species, both of which we will see represented in the trawl.
Similar to other estuaries, the Cape Fear provides nursery habitat for many species. We’ll collect shrimp and learn how to distinguish between species. There will also be many other invertebrates from the humble-looking sea squirt to the beautiful, yet irritable blue crab. The croakers and spot we pull in may look similar, but our expert eyes will pick up on the subtle differences. We may even see rays, turtles, or dolphins as we get further down the river. This fun, sometimes messy experience is an important look into the field of marine biology.
Support Sea Turtle Rescue and Rehabilitation
Please help us continue to protect and conserve the remaining species of Sea Turtles. Through education and public awareness we can ensure that future generations will be able to enjoy the natural wonder of these magnificent marine species.
Please consider giving a membership to the Karen Beasley Sea Turtle Hospital Foundation for birthdays and other special occasions.
Thank you for your interest and support.
