If the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation – conversion of liquid water to water vapor. In this manner, the salinity is increased, since the salt behind. If this is carried to the extreme, of course, white crystals of salt would be left behind.

The opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.

Normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.

A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.

In the Weddell Sea, off Antarctica, the densest water in the ocean is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portions of the oceans of the world.

In today’s fast-paced industry, learning will most likely involve seeking new skills in ways that challenge the norm. But thankfully, there is promise for such lifelong learning online – a promise that will save you time and money while helping you earn more of both.

Provided you have access to a decent computer and the Internet, the barrier to getting started is probably lower than it ever has been. And with those things in place, it is a matter of finding the content you wish to learn. So, to help others who may be looking to maximize their own learning efforts, I have listed some quick tips below.

First, set achievable goals. When you start learning, it is a good idea to set goals about what you want to learn or what you might do with your newly acquired knowledge. It might be landing that new job, building a tangible product, or impressing your current management. The goals may vary in size and complexity, but do revisit these goals throughout your learning process. Within a couple weeks ask yourself, “Am I getting closer to my goal?” or “Am I learning the skills necessary to reach my goals?” If you are not, then you may need to look elsewhere.

Second, learn with others. By yourself, learning anything has a high propensity to become frustrating. Try teaming up with friends or colleagues. They can often be your best resource for maintaining motivation while you learn.

Third, make it a habit. Online habits often include scrolling through social media or watching videos on YouTube. If you have the downtime for such activities, then you could spend that downtime learning something. And why not learn something? If you do, then you will have plenty more to talk about on social media anyways. So, make learning your new online habit by making a commitment to learn something new each day.
