Ocean acidification in the Arctic Ocean Ocean acidification in the Arctic Ocean The Arctic ocean has experienced drastic change over the years due to global warming. It has been known that the Arctic ocean acidity levels have been increasing and at twice the rate compared to the Pacific and Atlantic oceans. The loss of sea ice has been connected to a decrease in pH levels in the ocean water. Sea ice has experienced an extreme reduction over the past 30 years, forming a minimum area of 2.9×106 km at the end of the boreal summer of 2007, 47%, less than in 1980. Sea ice limits the
Ecoregions in the Philippines Ecoregions in the Philippines The Philippine archipelago is one of the world's great reservoirs of biodiversity and endemism. The archipelago includes over 7000 islands, and a total land area of 300,780 km². The Philippines was never connected to mainland Asia via land bridges, so the flora and fauna of the islands had to cross ocean straits to reach the Philippines. The Philippines is part of the Indomalaya ecozone, and its flora and fauna is mostly derived from tropical Asia.
