        While over 100 miles away from land, there are still some fantastic ways to experience the Monument including recreational fishing and bird and mammal viewing (like whale watching).

        Projects and Research

        Since the early 1900s, researchers have recognized the uniqueness of the waters and submerged lands within the monument boundaries. This recognition has piqued the interests of oceanographers, including physical, geological, chemical, and biological oceanographers.
