How do oceanographers use their measurements of the conductivity of seawater apex?
Oceanographers must measure the conductivity of seawater. As conductivity is directly related to salinity, oceanographers can use an instrument called a CTD (conductivity, temperature, depth) to detect how the conductivity and temperature changes relative to depth.
How do you calculate the salinity of seawater?
Calculate salinity, using the formula: salinity (ppt) = 0.0018066 5 Cl– (mg/L). 1. This test can be conducted on site or in the lab.

How do oceanographers measure the temperature of ocean water?
Physical oceanographers routinely use satellites to gain measurements over large distances and areas. Instruments on satellites can measure ocean height and thereby allow estimations of ocean surface temperature.
In what way does the ocean water move globally?
Ocean water is constantly in motion: north-south, east-west, alongshore, and vertically. Seawater motions are the result of waves, tides, and currents (Figure below). Ocean movements are the consequence of many separate factors: wind, tides, Coriolis effect, water density differences, and the shape of the ocean basins.
Which factors affect the movement of ocean currents Brainly?
Answer. ocean currents can be generated by wind,density and differences in water masses caused by temp. and salinity variations,gravity and events such as floods ,earthquakes.
How do you test water salinity?
Salinity is measured indirectly by testing the electrical conductivity (EC) of the water. Saltwater conducts more electricity than water with no dissolved salt. Fresh water has almost no dissolved salt, whereas ocean water has a salinity in the range of around 34 to 36 parts per thousand (ppt).
Why do we measure salinity in water?
So the two reasons you measure salinity – one is it tells you something about evaporation and precipitation at the surface of the ocean – so rainfall and evaporation, which are important to understand in the hydrological cycle – and the other reason you measure salinity is because of its impact on density, and …
How do oceanographers define salinity?
Ocean salinity is generally defined as the salt concentration (e.g., Sodium and Chlorure) in sea water. It is measured in unit of PSU (Practical Salinity Unit), which is a unit based on the properties of sea water conductivity. It is equivalent to per thousand or (o/00) or to g/kg.
How do Oceanographers measure the salinity of ocean water Brainly?
Answer and Explanation:Oceanographers can measure the salinity of a body of water in several ways, but the two most common methods are using a hydrometer set or a salinometer. A hydrometer set consists of a cylinder, a hydrometer, a thermometer, and a temperature-salinity-density or TSD graph.

How does salinity and density move ocean currents?
As the seawater gets saltier, its density increases, and it starts to sink. Surface water is pulled in to replace the sinking water, which in turn eventually becomes cold and salty enough to sink. This initiates the deep-ocean currents driving the global conveyer belt.
How do ocean waves move?
Waves are created by energy passing through water, causing it to move in a circular motion. However, water does not actually travel in waves. Waves transmit energy, not water, across the ocean and if not obstructed by anything, they have the potential to travel across an entire ocean basin.
What are the factors affect the movement of ocean water?
characteristics like temperature, salinity, density and the external forces like of the sun, moon and the winds influence the movement of ocean water.
Which factor do oceanographers determined by measuring the salinity of ocean water?
Oceanographers measure the salinity of ocean water by using a hydrometer, a hydrometer set, a chemical test kit or a salinometer. A hydrometer is a quick test tool used in aquariums, and it works by reading the water density. Higher dissolved salts result in higher density.
Which factors affect the movement of ocean currents apex?
Temperature, winds, gravitational pull of the sun, the earth and the moon, warm and cold currents are the factors that effects the movement of ocean water.
What is meant by the term salinity?
The term salinity refers to the amount of dissolved salts that are present in water. Sodium and chloride are the predominant ions in seawater, and the concentrations of magnesium, calcium, and sulfate ions are also substantial.
How do you measure salinity without a hydrometer?
An electrical conductivity meter, or EC meter, is the only common device that can be used to measure the salinity of soil. It can also be used to measure the salinity of water, but a high-quality EC meter may be significantly more expensive than a refractometer or hydrometer.

How is water measured?
For water that is in motion, cubic feet per second (cfs) is the unit of measure. For water that is stored or impounded, the acre-foot (af) is how water is measured. Cubic feet per second (cfs): * 1 cubic foot = 7.4805 gallons.
How does a refractometer measure salinity?
Salinity can be conveniently measured in a ballast water tank using a refractometer. The instrument works on the critical angle principle, utilizing lenses and prisms to project a shadow line onto a small glass reticle inside the refractometer, which is then viewed by the inspector through a magnifying eyepiece.
