Vulcan Materials Company (), is an American company based in Birmingham, Alabama.
 It is principally engaged in the production, distribution and sale of construction materials.
 Vulcan is the largest producer of construction materials, primarily gravel, crushed stone, and sand, and employs approximately 7,000 people at over 300 facilities.
 Vulcan serves 19 states, the District of Columbia and Mexico.
 Vulcan's innovative Crescent Market project led to construction of a large quarry and deep water seaport on the Yucatán Peninsula of Mexico, just south of Cancun.
 This quarry supplies Tampa, New Orleans, Houston, and Brownsville, Texas, as well as other Gulf coast seaports, with crushed limestone via large 62,000 ton self discharging ships.
North Atlantic Deep Water (NADW) is a deep water mass formed in the North Atlantic Ocean.
 Thermohaline circulation of the world's oceans involves the flow of warm surface waters from the southern hemisphere into the North Atlantic.
 Water flowing northward becomes modified through evaporation and mixing with other water masses, leading to increased salinity.
 When this water reaches the North Atlantic it cools and sinks through convection, due to its decreased temperature and increased salinity resulting in increased density.
 NADW is the outflow of this thick deep layer, which can be detected by its high salinity, high oxygen content, nutrient minima, and chlorofluorocarbons (CFCs).
 CFCs are anthropogenic substances that enter the surface of the ocean from gas exchange with the atmosphere.
 This distinct composition allows its path to be traced as it mixes with Circumpolar Deep Water (CDW), which in turn fills the deep Indian Ocean and part of the South Pacific.
 NADW and its formation is essential to the Atlantic Meridional Overturning Circulation (AMOC), which is responsible for transporting large amounts of water, heat, salt, carbon, nutrients and other substances from the Tropical Atlantic to the Mid and High Latitude Atlantic.
 In the conveyor belt model of thermohaline circulation of the world's oceans, the sinking of NADW pulls the waters of the North Atlantic drift northward; however, this is almost certainly an oversimplification of the actual relationship between NADW formation and the strength of the Gulf Stream/North Atlantic drift.
Via deep water aeration or hypolimnetic aeration, the oxygen demand of deep water is covered by oxygen from the atmosphere without destroying the lake’s natural stratification.
 Thus the deep water becomes aerobic, the phosphate dissolution is reduced significantly and the mineralization of sediments improves.
Hamriyah Port is deep water seaport and ancillary facilities located in the Hamriyah Free Zone in Sharjah, United Arab Emirates.
Deep Water Acres is a US-based independent webzine and record label dedicated to experimental music.
 Originally a physical magazine called "Deep Water", the Internet publication features musical commentaries, reviews, artist profiles and interviews as well as Australian campfire recipes.
 Since 2005, "Deep Water" also operates as an independent record label under the name Deep Water Sonic Productions.
 The label has so far released over 40 full length CDs of experimental music, covering acts such as Ashtray Navigations, Agitated Radio Pilot, United Bible Studies, Niagara Falls, The Goner, Evening Fires, Heavy Winged, Brother Ong, Dead Sea Apes and Alligator Crystal Moth.
Searsport is an incorporated town and deep water seaport located at the confluence of the Penobscot River estuary and the Penobscot Bay immediately SE of Sears Island and Cape Jellison in Waldo County, Maine, United States.
 The population was 2,615 at the 2010 census.
 Searsport includes the village of North Searsport.
 The town is known as "the home of the famous sea captains" and the "Antique Capital of Maine".
The Port of Brownsville is a deep water seaport in Brownsville, at the southern tip of Texas.
The Port of Bridgetown (officially the Deep Water Harbour), (AMS Seaport Code: 27201, UN/LOCODE: BB BGI, Port Callsign: 8PB) is a seaport in Bridgetown on the southwest coast of Barbados.
 Situated at the North-Western end of Carlisle Bay, the harbour handles all of the country's international bulk ship-based trade and commerce.
 In addition to international-shipping the Deep Water Harbour is the port of entry for southern-Caribbean cruise ships.
 The port is one of three designated ports of entry in Barbados, along with the privately owned Port Saint Charles marina and the Sir Grantley Adams International Airport.
 The port's timezone is GMT −4, and it handles roughly 700,000 cruise passengers and 900,000 tonnes of containerised cargo per year.
The Penobscot Marine Museum in Searsport, Maine, United States, is Maine's oldest maritime museum and is designed to preserve and educate people regarding Maine's and Searsport's rich and unique maritime and shipbuilding history.
 It was founded in 1936, and is located at 5 Church Street in the center of Searsport.
Deep Water is a 2009 novel in the Cliff Hardy series by Peter Corris.
 In April 2009, The Independent Weekly called "Deep Water" "a web of intrigue".
 Deep Water is the thirty fourth novel in the series, whose protagonist has been called "Sydney’s best-known private investigator" In 2009, Corris won the Ned Kelly Award for "Deep Water" in the fiction category.
