  • Is Offshore Wind Development a Threat to the North Atlantic Right Whale?

    Submitted by Luke Hanna on
    Since 1980, the North Atlantic Right Whale (Eubalaena glacialis) population has experienced a rapid decline, mainly due to fishing gear entanglements and collisions with shipping vessels.  Prior to 1980 the whaling industry also took its toll on the whales; the North Atlantic Right Whale (NARW) population size is now estimated to be 300-350 individuals and faces a serious threat of extinction.… Read More

  • Coastal Wave Parks Should Not Interfere with Gray Whale Migrations

    Submitted by Andrea Copping on
    Twice each year, east Pacific gray whales (Eschrichtius robustus) swim between their breeding grounds in Baja California and their main feeding areas in the Bering Sea. This round-trip swim of about 15,000 to 20,000 km (8100 to 10,800 nmi) is one of the longest known migrations by a mammal (Shelden et al. 2004). The whales’ migration route is somewhat unusual because it follows very close to the… Read More

  • Offshore Wind Environmental Effects Evaluation Tool

    Submitted by Andrea Copping on
    The purpose of this tool is to provide an easy to use, all inclusive tool to examine the environmental effects of offshore wind development. The goal being to streamline and facilitate the siting and permitting of offshore wind farms in the U.S. The Zephyrus tool will identify the highest environmental risks by 1) providing a science-based system to evaluate risk information, and making that… Read More
