War in the Pacific National Historical Park (WAPA) commemorates those who participated in the World War II Campaign in the Pacific. The 75th anniversary of the Battle of Guam will be celebrated in July 2019 during this internship.The Park contains the historic beaches where US soldiers and marines landed during the battle to liberate Guam from Japanese war time occupiers. Over half the Park area consists of shallow fringing coral reefs that were heavily bombed and damaged during landing of the US forces in July 1944. The reefs have recovered from extensive war damage and contain the highest diversity of marine species among all national parks. But they are under serious threat from coral bleaching, diseases and death of reef organisms caused by recent marine environmental changes.
