Papahānaumokuākea Marine National Monument

Marine pollution: nets and plastic debris

The Papahānaumokuākea Marine National Monument Created by President Bush in 2006 Encompasses 137,797 square miles of the Pacific Ocean (105,564 square nautical miles) - an area larger than all the country's national parks combined.

The Monument is part of your natural heritage! The monument benefits from the most stringent environmental protection and ongoing scientific research The extensive coral reefs found in Papahānaumokuākea - truly the rainforests of the sea - are home to over 7,000 marine species! It is a place of great cultural significance to the Hawaiian people

They are part of the Hawaiian Ridge-Emperor Seamounts chain. The chain extends some 3,700 miles from the island of Hawaii to the Aleutian Trench off the coast of Siberia. Northwestern Hawaiian Islands

Midway Atoll

Kure Atoll Kure Atoll is the farthest island group from Honolulu (about 1,400 miles). The atoll is comprised of a circular reef 5 miles in diameter and the largest island (Green in photo above) is only 1.5 miles long. Mined for guano (bird manure) by Australian Copra & Guano Ltd. from 1876 until 1936.

Even in the most remote places on earth… Marine debris piles up The Northwest Hawaiian Islands are part of the most isolated island chain in the world but… Ocean currents can carry debris for thousands of miles and… Plastic debris can last for decades!
