Abstract:
A unique approach to counting bottlenose dolphins in North Carolina waters was conducted recently. Instead of tagging the dolphins with physical markers researchers used a \"mark- recapture\" technique in which dolphins were photographed and then recaptured on film a week later. Henderson discusses the study and what the research learned.

Abstract:
Ecotourism is increasing along North Carolina's coast, with high interest in birding and marine mammal observation. In 1999, the North Carolina Sea Grant staff conducted a survey to learn tourists' environmental interests and the impact of commercial dolphin-watch enterprises on the Outer Banks. Among the findings were that over 50 percent of tourists wanted to known more about the marine environment, but 80 percent knew little or nothing about the Marine Mammal Protection Act passed in 1972. The survey focused on tourists who came to the Outer Banks to see bottlenose dolphins.

Abstract:
Between 1992 and 2001, in coastal waters from New Jersey to North Carolina, 210 bottlenose dolphins were killed by becoming entangled in gill nets used by fishermen. The dolphins become entangled either by accidentally running into the nets or by being caught while eating the fishing catch. Angione reports on a study funded by the North Carolina Fishery Resource Grant program to study whether acoustic alarms can keep the dolphins away from the gill nets.
