Question: What ocean is home of the Hawaiian-Emperor seamount chain and Kure Atoll?

full_context: Document 1: Detroit Seamount: Detroit Seamount, which was formed around 76 million years ago, is one of the oldest seamounts of the Hawaiian-Emperor seamount chain (Meiji Seamount is the oldest, at 82 million years). It lies near the northernmost end of the chain and is south of Aleutian Islands (near Russia), at It is a seamount in the chain, located north of the hinge of the "V" in the image at right.
Document 2: Hawaiian–Emperor seamount chain: The Hawaiian–Emperor seamount chain is a mostly undersea mountain range in the Pacific Ocean that reaches above sea level in Hawaii. It is composed of the Hawaiian ridge, consisting of the islands of the Hawaiian chain northwest to Kure Atoll, and the Emperor Seamounts: together they form a vast underwater mountain region of islands and intervening seamounts, atolls, shallows, banks and reefs along a line trending southeast to northwest beneath the northern Pacific Ocean. The seamount chain, containing over 80 identified undersea volcanoes, stretches over 5800 km from the Aleutian Trench in the far northwest Pacific to the Loʻihi seamount, the youngest volcano in the chain, which lies about 35 km southeast of the Island of Hawaiʻi.
Document 3: Meiji Seamount: Meiji Seamount, named after Emperor Meiji, the 122nd Emperor of Japan, is the oldest seamount in the Hawaiian-Emperor seamount chain, with an estimated age of 82 million years. It lies at the northernmost end of the chain, and is perched at the outer slope of the Kuril-Kamchatka Trench. Like the rest of the Emperor seamounts, it was formed by the Hawaii hotspot volcanism, grew to become an island, and has since subsided to below sea level, all while being carried first north and now northwest by the motion of the Pacific Plate. Meiji Seamount is thus an example of a particular type of seamount known as a guyot, and some publications refer to it as Meiji Guyot.
Document 4: United States Minor Outlying Islands: The United States Minor Outlying Islands, a statistical designation defined by the International Organization for Standardization's ISO 3166-1 code, consist of eight United States insular areas in the Pacific Ocean (Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Atoll, Palmyra Atoll, and Wake Island) and one in the Caribbean Sea (Navassa Island).
Document 5: Mokolea Rock: Mōkōlea Rock is an islet in Kailua Bay along the windward coast of Oʻ ahu in Hawaiʻ i and located east of Marine Corps Base Hawaii (MCBH). Like most of the small islets off the coastline of a major island in the Hawaiian Islands, Mōkōlea is a State Bird Sanctuary containing many types of birds. Access to the islet requires a permit, and is only allowed to people involved in protecting the islet's fauna. The islet is more commonly known to local residents as "Birdshit Island", "Birdshit", or simply "Bird" because its black lava rock surface is heavily coated with bird droppings.
Document 6: Wake Island: Wake Island (also known as Wake Atoll) is a coral atoll in the western Pacific Ocean in the northeastern area of the Micronesia subregion, 1,501 mi east of Guam, 2,298 mi west of Honolulu and 1,991 mi southeast of Tokyo. The island is an unorganized, unincorporated territory of the United States Minor Outlying Islands that is also claimed by the Republic of the Marshall Islands. Wake Island is one of the most isolated islands in the world and the nearest inhabited island is Utirik Atoll in the Marshall Islands, 592 mi to the southeast.
Document 7: Lōʻihi Seamount: Lōʻihi Seamount (also known as Loihi) is an active submarine volcano about 35 km off the southeast coast of the island of Hawaiʻi. The top of the seamount is about 975 m below sea level. This seamount is on the flank of Mauna Loa, the largest shield volcano on Earth. Lōʻihi, meaning "long" in Hawaiian, is the newest volcano in the Hawaiian-Emperor seamount chain, a string of volcanoes that stretches over 5800 km northwest of Lōʻihi. Unlike most active volcanoes in the Pacific Ocean that make up the active plate margins on the Pacific Ring of Fire, Lōʻihi and the other volcanoes of the Hawaiian-Emperor seamount chain are hotspot volcanoes and formed well away from the nearest plate boundary. Volcanoes in the Hawaiian Islands arise from the Hawaiʻi hotspot, and as the youngest volcano in the chain, Lōʻihi is the only Hawaiian volcano in the deep submarine preshield stage of development.
Document 8: Kure Atoll: Kure Atoll (呉ヶ島 , Kure-gashima ) ( ; Hawaiian: "Mokupāpapa" ) or Ocean Island is an atoll in the Pacific Ocean 48 nmi beyond Midway Atoll in the Northwestern Hawaiian Islands at . The only land of significant size is called Green Island and is habitat for hundreds of thousands of seabirds. A short, unused and unmaintained runway and a portion of one building, both from a former United States Coast Guard LORAN station, are located on the island. Politically it is part of Hawaii, although separated from the rest of the state by Midway, which is a separate unorganized territory.
Document 9: Evolution of Hawaiian volcanoes: The fifteen volcanoes that make up the eight principal islands of Hawaiʻ i are the youngest in a chain of more than 129 volcanoes that stretch 5800 km across the North Pacific Ocean, called the Hawaiian-Emperor seamount chain. Hawaiʻ i's volcanoes rise an average of 4572 m to reach sea level from their base. The largest and most famous, Mauna Loa, has built itself up to a height of 4169 m . As shield volcanoes, they are built by accumulated lava flows, growing no more than 3 m at a time to form a broad and gently sloping shape.
Document 10: Howland Island: Howland Island is an uninhabited coral island located just north of the equator in the central Pacific Ocean, about 1700 nmi southwest of Honolulu. The island lies almost halfway between Hawaii and Australia and is an unincorporated, unorganized territory of the United States. Geographically, together with Baker Island it forms part of the Phoenix Islands. For statistical purposes, Howland is grouped as one of the United States Minor Outlying Islands.
Document 11: Abbott Seamount: Abbott Seamount is a seamount lying within the Hawaiian-Emperor seamount chain in the northern Pacific Ocean. It erupted 36-40 million years ago.
Document 12: Kammu Seamount: Kanmu Seamount is a seamount lying within the Hawaiian-Emperor seamount chain in the Pacific Ocean. The last eruption of Kanmu Seamount is unknown.
Document 13: Midway Atoll: Midway Atoll ( ; also called Midway Island and Midway Islands; Hawaiian: "Pihemanu Kauihelani") is a 2.4 sqmi atoll in the North Pacific Ocean at . As its name suggests, Midway is roughly equidistant between North America and Asia. Midway Atoll is an unorganized, unincorporated territory of the United States. Midway continues to be the only island in the Hawaiian archipelago that is not part of the state of Hawaii. Unlike the other Hawaiian islands, Midway observes Samoa Time (, i.e., eleven hours behind Coordinated Universal Time), which is one hour behind the time in the state of Hawaii. For statistical purposes, Midway is grouped as one of the United States Minor Outlying Islands. The Midway Atoll National Wildlife Refuge, encompassing 590991.50 acre of land and water (mostly water) in the surrounding area, is administered by the United States Fish and Wildlife Service (FWS). The refuge and most of its surrounding area are part of the larger Papahānaumokuākea Marine National Monument.
Document 14: Line Islands: The Line Islands, Teraina Islands or Equatorial Islands, is a chain of atolls (with partially or fully enclosed lagoons) and coral islands (with a surrounding reef). Kingman Reef is a largely submerged and Filippo Reef is shown on some maps, although its existence is doubted. The islands were formed by volcanic activity and are located in the central Pacific Ocean, south of the Hawaiian Islands. The 11 islands stretch for 2,350 km in a northwest–southeast direction, making it one of the longest island chains of the world. Eight of the islands form part of Kiribati, while the remaining three are United States territories grouped with the United States Minor Outlying Islands. Only Kiritimati and Tabuaeran atolls and Teraina Island have a permanent population.
Document 15: North Keeling: North Keeling is a small, uninhabited coral atoll, approximately 1.2 km2 in area, about 25 km north of Horsburgh Island. It is the northernmost atoll and island of the Australian territory of the Cocos (Keeling) Islands. North Keeling comprises just one C-shaped island, a nearly closed atoll ring with a small opening into the lagoon, about 50 m wide, on the east side. The lagoon is about 0.5 km2 in area. The island is home to the only surviving population of the endemic, and endangered, Cocos buff-banded rail, as well as large breeding colonies of seabirds. Since 1995, North Keeling Island and the surrounding sea to 1.5 km from shore have been within the Pulu Keeling National Park.
