  • Why Should We Care About Rising CO2?

  • Looking for Answers to Help Terrapins

    Diamondback terrapins were once abundant in our coast’s marshes, creeks and sounds. Their population has declined, and researchers at the University of North Carolina-Wilmington hope to find some answers.

  • Hydrilla: ‘The Kudzu of the Water’

    A little plant from Korea showed up in lakes around Raleigh 30 years ago. It now plagues the Roanoke, Chowan and Pasquotank rivers and has been spotted in Albemarle Sound. Biologists fear that pristine Lake Mattamuskeet and Lake Phelps could be next.

  • The Invasion of the Reed Plant

    A native plant that was once part of healthy coastal wetlands is being pushed aside by a foreign cousin that is invading our marshes, creating a barren ecosystem in its wake.

  • The Coast’s Underwater Gardens

    Only a few feet below the surface of the state’s coastal waters, expansive beds of eelgrass and shoal grass form underwater gardens where life flourishes.

  • Reviving Ocracoke’s Oysters

    Ocracoke residents gathered around a pot-bellied stove on a cold winter day to learn how to best monitor little oyster spats and thus bring about the revival of the species.

  • Bay Scallops: Hold the Applause, Please

    Bay scallop season will open later this month in some N.C. waters for the first time in years. While a harvest is good news and might in part be the result of improved water quality and seagrass beds, all is still not well for the tasty bivalve.
