AIS Ship Traffic: Mariana and Wake: 2011-2012
공공데이터포털
Ship position data from a satellite-based Automatic Identification System (AIS) were obtained jointly by PacIOOS (J. Potemra), SOEST/ORE of the University of Hawaii (E. Roth), and the Papahanaumokuakea Marine National Monument (PNMN) (D. Graham) through a one-time purchase from ORBCOMM LLC. The purchase agreement was made in late 2012 and was for a 30-by-30 degree section of historical AIS data that included the region of the Mariana Islands. The data include AIS long and unchecked reports for a one year period: August 2011 through mid-August 2012. The raw, monthly GPS files were locally converted to NetCDF for the PacIOOS data servers. Due to vendor constraints, release of the raw data is limited.
Papahanaumokuakea Marine National Monument (PMNM), 2006-2016 - Northwestern Hawaiian Islands (NWHI)
공공데이터포털
Boundary of the Papahanaumokuakea Marine National Monument (PMNM), located in the Northwestern Hawaiian Islands (NWHI). Created in 2006, Papahanaumokuakea is the largest conservation area in the U.S. and one of the largest marine conservation areas in the world. It is home to extensive coral reefs harboring over 7,000 marine species, one quarter of which are found only in Hawaii. Many of the islands and shallow water environments are important habitats for rare species such as the threatened green sea turtle and the endangered Hawaiian monk seal. Significant cultural Native Hawaiian sites can also be found on the islands of Nihoa and Mokumanamana (Necker Island). Co-managed with the State of Hawaii and the U.S. Department of the Interior, the monument preserves one of the most untouched areas of coral reef in the world. This layer shows the PMNM boundary prior to its expansion in 2016. On August 26, 2016, President Obama signed a proclamation expanding the monument from 139,797 square miles (362,073 square kilometers) to 582,578 square miles (1,508,870 square kilometers). This extended the monument boundary westward of -163 degrees longitude out to Hawaii's Exclusive Economic Zone (EEZ) at 200 nautical miles offshore. The present layer shows the monument boundary as it existed *before* this expansion. To view the expanded boundary, access the data layers for "hi_noaa_nwhi_papahanaumokuakea" or "hi_noaa_nwhi_papahanaumokuakea_line" instead.
