The acre is a unit of land area used in the imperial and US customary systems. It is traditionally defined as the area of one chain by one furlong, which is exactly equal to 10 square chains, 1⁄640 of a square mile, 4,840 square yards, or 43,560 square feet, and approximately 4,047 m2, or about 40% of a hectare. Based upon the International yard and pound agreement of 1959, an acre may be declared as exactly 4,046.8564224 square metres. The acre was sometimes abbreviated ac, but was often spelled out as the word "acre".
The United States National Geophysical Data Center (NGDC) provided scientific stewardship, products and services for geophysical data describing the solid earth, marine, and solar-terrestrial environment, as well as earth observations from space. In 2015, NGDC was merged with the National Climatic Data Center (NCDC) and the National Oceanographic Data Center (NODC) into the National Centers for Environmental Information (NCEI).
The National Oceanographic Data Center (NODC) was one of the national environmental data centers operated by the National Oceanic and Atmospheric Administration (NOAA) of the U.S. Department of Commerce. The main NODC facility was located in Silver Spring, Maryland and was made up of five divisions. The NODC also had field offices collocated with major government or academic oceanographic laboratories in Stennis Space Center, MS; Miami, FL; La Jolla, San Diego, California; Seattle, WA; Austin, Texas; Charleston, South Carolina; Norfolk, Virginia; and Honolulu, Hawaii. In 2015, NODC was merged with the National Climatic Data Center and the National Geophysical Data Center into the National Centers for Environmental Information (NCEI).

Trunk Bay is a body of water and a beach on St. John in the United States Virgin Islands. Trunk Bay is part of the Virgin Islands National Park. Trunk Bay is named for the Leatherback turtle, which is endemic to the USVI and are locally known as trunks. The beach area is divided into two halves, the main Trunk Bay beach and swim area and Burgesman Cove which is located on the west end of Trunk Bay near Jumby Bay.

Trunk Bay has consistently been voted one of the top beaches in the world.
Lovango Cay is a private island of the district of Saint John, in the United States Virgin Islands.

The neutral density or empirical neutral density is a density variable used in oceanography, introduced in 1997 by David R. Jackett and Trevor McDougall. It is a function of the three state variables and the geographical location. It has the typical units of density (M/V). Isosurfaces of form “neutral density surfaces”, which are closely aligned with the "neutral tangent plane". It is widely believed, although this has yet to be rigorously proven, that the flow in the deep ocean is almost entirely aligned with the neutral tangent plane, and strong lateral mixing occurs along this plane vs weak mixing across this plane . These surfaces are widely used in water mass analyses. Neutral density is a density variable that depends on the particular state of the ocean, and hence is also a function of time, though this is often ignored. In practice, its construction from a given hydrographic dataset is achieved by means of a computational code, that contains the computational algorithm developed by Jackett and McDougall. Use of this code is currently restricted to the present day ocean.
Pélé Island, sometimes spelled Pele in English, is a volcanic island located 11,2 miles north of the island of Éfaté in the Shefa Province of the Republic of Vanuatu. It has a total area of 1.7 square miles, Pélé is inhabited by about 200-220 Ni-Vanuatu villagers residing in the four villages: Worsiviu, Worearu, Piliura, and Launamoa. Pélé Island is a part of the MPA Nguna-Pele Marine Protected Area, which was established in 2003, and is a popular Vanuatuan diving location. The Nguna-Pele Marine Protected Area covers a total area of 11.5 sq. mi., including numerous reefs, sea grass beds, mangrove forests and intertidal lagoons. The Nguna-Pele Marine Protection Agency is located in the village of Piliura, and mounts an exhibition and sells T-shirts. Income from tourism is distributed by the Village Tourism Committee and supports aims as village water supply projects. The island can be visited daily by boat from the Paonangisu area by the town of Emua on Éfaté's north coast. There are also yachts available both from Emua and Nguna for day and overnight charters to the island. The island is nearly adjacent to the island of Nguna, with a small passage no deeper than 33 yards separating the two. It has a tropical climate and has a maximum elevation of 650 feet at its highest. Much of the island is extremely steep and rocks prevent you from walking along the coastline around the island. White sandy beaches are found in Piliura, Worearu, Laonamoa, and Sake. Overpopulation has led to a steady migration from Pele villages to southern Nguna in recent times.
Turtledove Cay is a rocky 3.78 acre islet, located 100 yards north of Saba Island in the United States Virgin Islands. Its elevation is 50 feet and the islet is covered with tall grass. It is joined with Saba Island by a reef, which is bare at times of extremely low water. Turtledove Cay are all designated wildlife reserves by the territorial U.S.V.I. government. Turtledove Cay is home to large quantities of native avifauna, including large colonies of noddies and other seabirds.
Trunk Cay is a small grass-covered islet in Trunk Bay in the United States Virgin Islands. It has an elevation of 48 feet and is situated only 200 feet from Trunk Bay Beach. It is an islet of rocky cliffs, coral sandy beaches, and palm trees. The Virgin Islands National Park Service offers underwater snorkelling trails around the cay. Trunk Cay is named for the leatherback turtle, which is found in the U.S.V.I. and is locally known as trunks.
Whistling Cay is a 19-acre (7.7 ha) islet, situated 300 yards (270 m) west of Mary Point on Saint John in the United States Virgin Islands. It is covered with trees and high cliffs in the north, where it reaches a 130-foot (40 m) elevation. A gravel beach is located on the southeast side of the island. It is separated from Saint John by the Fungi Passage, which has a depth of 21 feet (6.4 m).
Kalkun Cay is a rocky, steep and narrow islet, located in the middle of the Savana Passage in the United States Virgin Islands. It is one mile northeast of Savana Island and one mile west of West Point on the island of Saint Thomas. Kalkun Cay is 73 feet high and covered with underbrush and grass. It is an important habitat of native seabirds.
Leduck Island is an island in the United States Virgin Islands, also spelled LeDuck Island, which is located 0.5 miles east of Sabbat Point in Johns Folly, separated from Saint John by the Sabbat Channel.
