A wooden sluice or aboiteau (plural aboiteaux) is then built into the dyke, with a hinged door (clapper valve) that swings open at low tide to allow fresh water to drain from the farmland but swings shut at high tide to prevent salt water from inundating the fields.
Seawater from the Firth of Forth was used as a cooling medium.
200 billion m3 — estimated volume of the annual net inflow of seawater to the Black Sea (from the Mediterranean Sea via the Bosporus)
The International Standard for making Artificial Seawater can be found at ASTM International.
The Bottsand class oil recovery ships (Type 738) of the German Navy are intended for seawater pollution control.
The InterContinental Resort and Thalasso-Spa on the island of Bora Bora uses a seawater air conditioning (SWAC) system to air-condition its buildings.

The InterContinental Resort is the largest seawater air conditioning system to date, though there are several other, larger systems being planned.
Just three weeks later, Hurricane Jeanne uprooted trees, blew out windows, and sent seawater flooding through neighborhoods on the islands of Abaco and Grand Bahama.

After the Bikini Atoll nuclear tests in 1954, the Japanese government asked the Geochemical Laboratory to analyze and monitor radioactivity in the seawater and in rainfall.
In the interior there is a relict lake, Lake Mogil'noe (or Molginoye), which is separated from Kildin Strait by an isthmus through which seawater filters that replenishes the lake.
Chris Glovet, at the University of Canterbury in Christchurch, New Zealand, tested his theory by putting skin samples of the hagfish in between nutrient rich seawater and a solution similar to the hagfish's body fluids.
From 1415 to 1423 it was the home of the schismatic Avignon pope Benedict XIII (Pedro de Luna), whose name is commemorated in the Bufador de Papa Luna, a curious cavern with a landward entrance through which the seawater escapes in clouds of spray.
Joints in any equipment carrying seawater must be welded (not brazed), and every hull penetration larger than a specified size can be quickly shut by a remote hydraulic mechanism.
For example, concentrations of PCBs and DDE on nurdles collected from Japanese coastal waters were found to be up to 1 million times higher than the levels detected in surrounding seawater.
In a seawater RO system operating at a 40% membrane water recovery rate, the ERD supplies 60% of the membrane feed flow.

In 1961, the hatch of Mercury-Redstone 4 was prematurely detached and the capsule was filled with seawater.
A survey of the wreck showed no obvious indication of weapon attack being the cause of loss (although this could not be ruled out; damage assessment expert David Manley (author) determined that shock damage from a depth charge attack could have caused loss through failure of internal seawater systems and hull penetrations that would not be obvious from an external examination).
In October 2011 the a second seawater desalination plant was opened in Caofeidian, supplying 50,000 cubic meters per day for industrial uses in the Tianjin area.
