In this segment, we explore factors controlling the salinity of the surface waters of the world ocean.

A sensor is designed to check salinity of the solution.

A laboratory demonstration of salinity measurements

We built a device to increase the salt content of a solution. This robot utilizes the Vernier Salinity Sensor connnected to the NXT. The purpose of the device is to increase the salt content (salinity) of a solution in a beaker. The program specifies a salinity level. Distilled water is in the beaker. The center stirring mechanism (held in place by a pulley system) is lowered down into the beaker, so the stirring rod and salinity probe are submerged. After the mechanism is lowered, the stirring rod begins to spin; it will do this for 10 full motor rotations. Then the stirring rod will stop and the claw holding the salt shaker is rotated forward, then back, adding salt. The process then repeats until the desired salinity is reached. When the specified salinity is reached, the NXT will beep, then the stirring motor will stop, and the center apparatus is pulled up until the mechanism presses an NXT touch sensor, signaling that the pulley motor should stop.

I taste test some canal water to see how salty it is. It was more bitter than salty. A lesson in what not to do with only 4 hours of sleep.

Salinity in South Australia's Lower Lakes is crippling livestock producers, with one family deciding to completely destock its beef cattle herd. As seen on www.farmonline.com.au From agricultural news, weather, classifieds and market reports to properties for sale, job vacancies and rural events, farmonline has it covered.

A video from ESA regarding the SMOS (soil moisture and ocean salinity) mission. Video date- 11th Feb 08 Source- http://www.esa.int/esa-mmg/mmghome.pl 'To help address climate change, 2008 will see the launch of Europe's SMOS satellite. SMOS, which stands for soil moisture and ocean salinity, is designed to map these elements with unprecedented accuracy. Three-quarters of the globe is covered in water and its influence is felt everywhere. It's not only oceans, rivers and lakes that affect the climate but water in all its forms, such as soil moisture and its evaporation. SMOS, ESA's water mission, will provide a uniform dataset for understanding better the water cycle, thus helping to forecast climate change and predict extreme weather conditions. Circulating at a low orbit of around 750 km above the Earth, SMOS will be the first satellite to provide us with a global picture of ocean salinity levels. Understanding the salinity and temperature of the seas will help to predict more easily the zones where hurricanes intensify as they pass over the ocean. Salinity in the oceans has a big impact on ocean circulation, which plays a key role in driving the global climate. The SMOS satellite will be launched into space in 2008 atop the Russian launcher 'Rockot'.'

Dead Sea ים המלח Herbet 2007 The Dead Sea (Arabic: البحر الميت‎, Hebrew: ים המלח‎) is the Earth's lowest point not covered by water, at 418 m (1371 feet) below sea level and falling, and the deepest hypersaline lake in the world, at 330 m (1083 feet) deep. It is the second saltiest body of water on Earth, with a salinity of about 30 percent. Only Lake Asal (Djibouti) has a higher salinity. This is about 8.6 times greater than average ocean salinity. It measures 67 km (42 miles) long, 18 km (11 miles) wide at its widest point, and is located on the border between the West Bank, Jordan, and Israel, and lies in the Jordan Rift Valley. The main tributary is the Jordan River. The Dead Sea has attracted interest and visitors from around the Mediterranean basin for thousands of years. It was a place of refuge for King David, one of the world's first health resorts (for Herod the Great), and it has been the supplier of products as diverse as balms for Egyptian mummification to potash for fertilizers

Salt lowers the freezing point of water. Normally, water freezes at 0°C = 32°F. The salinity of the Great Salt Lake is between 5% -27% (compare to ocean salinity of 3.5%). During the first week of 2008 the temperatures dropped to -9 ° C = 16°F around the Great Salt Lake and Antelope Island in Utah. Su'da tuz oranı yükseldıkce buz tutabilmezı için gereken derece daha düşük olmasi gerekiyor. Su genelinde 0°C buz tutar. Utah eyaletinde bulunan büyük tuz gölünün tuz oranı 5% - 27% civarında. Karşılaştırmak maksatıyla: denız'ın tuz oranı genelinde 3.5%. 2008 yıl'ın birıncı haftasında tuz gölde ve Antelope adasında derece -9 ° C göstermıştı.

An ocean is a major body of saline water, and a principal component of the hydrosphere. Approximately 71% of the Earth's surface (an area of some 361 million square kilometers) is covered by ocean, a continuous body of water that is customarily divided into several principal oceans and smaller seas. More than half of this area is over 3,000 meters (9,800 ft) deep. Average oceanic salinity is around 35 parts per thousand (ppt) (3.5%), and nearly all seawater has a salinity in the range of 30 to 38 ppt.
