Papahānaumokuākea Marine National Monument

Establishment: In June 2006, Papahānaumokuākea Marine National Monument in the Northwestern Hawaiian Islands (NWHI) was established, by Presidential Proclamation 8031, encompassing several previously existing federal and State of Hawaii conservation areas including the Northwestern Hawaiian Island (NWHI) Coral Reef Ecosystem Reserve, Hawaiian Islands National Wildlife Refuge, Northwestern Hawaiian Islands State Marine Refuge, Midway Atoll National Wildlife Refuge, Battle of Midway National Memorial, and the Kure Atoll Seabird Sanctuary.

Size: The total Monument area consists of approximately 139,797 m2 (362,075 km2) of Pacific Ocean in the Northwestern region of the Hawaiian Archipelago.

Recent Research

  • Coral Reefs - In 2014, scientists in the Pacific Islands Fisheries Science Center (PIFSC) used baited and unbaited remote underwater video systems (BRUVs) in waters up to 100m in depth, well below depths comfortably reached by scuba divers (<30 m). By synchronizing the images from each camera and using special software, scientists can accurately identify and enumerate fishes that pass in front of the BRUV and estimate their size and position. Data collected during these missions will be used to assess the abundance and distribution of roving piscivores, particularly sharks and jacks. Click here to read more...
  • Marine Mammals - During the months of June - August 2014, PIFSC Scientists in the Hawaiian Monk Seal Research Program conducted research and monitoring of Hawaiian monk seals utilizing NOAA Ship Hiʻialakai as a research support platform. Each year, scientists monitor the status of monk seals at remote locations in the NWHI and conduct research to better understand factors affecting abundance of the seals and ways to enhance the population's recovery.
