The Marianas Trench Marine National Monument is a United States National Monument created by President George W. Bush by the presidential proclamation no. 8335 on January 6, 2009. The monument includes no dry land area, but protects 95,216 square miles (246,610 km2) of submerged lands and waters in various places in the Mariana Archipelago. The United States could create this monument under international law because the maritime exclusive economic zones of the adjacent Northern Mariana Islands and Guam fall within its jurisdiction.
Typhoon Joan was the longest-lasting super typhoon at the time, maintaining 1-minute maximum sustained winds of at least 240 km/h (150 mph) for 4.5 days. Joan, concurrently with Typhoon Ivan to its west, also became the strongest typhoons at the same time in the northwest Pacific Ocean. The 25th named storm during the hyperactive 1997 Pacific typhoon season, Joan developed from the same trough as Typhoon Ivan on October 11. It moved northwestward and later to the west, undergoing explosive deepening to its peak intensity on October 15. One typhoon warning agency estimated that Joan was among the strongest storms on record in the basin, and that Ivan and Joan marked the first occurrence of simultaneous super typhoons. While near peak intensity, Joan passed between Anatahan and Saipan in the Northern Marianas Islands. Later, the typhoon weakened and turned to the north and east, becoming extratropical on October 24.

Daikoku Seamount is a submarine volcano located in the Northern Mariana Islands, in the western Pacific Ocean. It is part of a chain of volcanoes and seamounts that includes the more known Ahyi Seamount and NW Rota-1 seamounts and is situated about 690 km (429 mi) north of the island of Saipan. Daikoku Seamount rises over 2,500 m (8,202 ft) meters from the seafloor, with its summit about 323 m (1,060 ft) below sea level. Since its discovery, the seamount has been studied by several expeditions, including expeditions made by NOAA, using various scientific tools, such as sonar mapping and remotely operated vehicles (ROVs). Daikoku Seamount is known for its active hydrothermal vent system, which hosts diverse communities of deep-sea organisms, including tube worms, crabs, and snails. The seamount is also one of the only volcanoes along with Nikkō Seamount to have had a partially molten sulfur lake, which is usually a feature seen on Io than on Earth.
