In recent years, melting sea ice has allowed more Pacific water to flow into the Arctic Ocean and build up there. There are glaciers, ice sheets and so many huge icebergs covering most parts of the ocean. The Arctic Ocean is the smallest and shallowest of the world's five major oceans. Marine sediments from the Gulf of Alaska show that increases in vertical mixing of the ocean there correspond with . According to the USGS Navigation Center, icebergs are found in many parts of the world's oceans, but perhaps the best-known location is the western North Atlantic Ocean, which is where the RMS Titanic struck an iceberg and sank in 1912. It is regarded as one of the toughest maritime places in the world to round by ship or yacht. The Arctic Ocean. the Southern Ocean is 4,000 to 5,000-m deep over most of its extent with only limited areas of shallow water; the Antarctic continental shelf is generally narrow and unusually deep, its edge lying at depths of 400 to 800 m (the global mean is 133 m); the Antarctic icepack grows from an average minimum of 2.6 million sq km in March to about 18.8 .
