The questions what causes polar ice to melt, variation in temperature at same latitudes, climate change and others have led meteorologist, ocean scientist and other researchers to investigate currents. According to the oxforddictionaries.com, a current is a body of water or air moving in a definite direction, especially through a surrounding body of water or air in which there is less movement. Currents can be generated both on the ocean surface flowing horizontally and sub surface flowing vertically. However these currents are generated by different factors. Horizontal currents are generated by the wind blowing across the ocean surface while vertical currents are generated by the density differences in water masses caused by temperature and salinity variation. To understand the significance of these currents researchers used a number of oceanographic tools which incorporates different techniques to measure them. The Lagrangian measurement incorporates all drifter measurements, which was named after the mathematician Joseph Louis Lagrange while the Eulerian measurement incorporates measuring currents of a fluid at only a given point and was named after Swiss mathematician Leonhard Euler (oceanservice.noaa.gov). Ocean currents are typically measured in Knots. According to NOAA ocean service education, Knot is defined as one nautical mile per hour and is used to measure speed (oceanservice.noaa.gov).
Oceanographic Tools to Measure Currents
Incorporating both the Lagrangian and Eulerian measurements allowed researchers to measure both surface and sub surface currents. The floating devices, which scientist call a ‘drifter’, to take the measure surface current as well as devices which scientist call a ‘profiling floats’ ,...

When two currents flow towards each other on show it pushes the flow of the current outward which causes a rip current. Rip current can be dangerous but it is an easy way for surfers to get out in the sea and catch the wave.

- Horizontal and vertical ocean currents Ocean currents are horizontal or vertical movement of both surface and deep water throughout the world’s oceans (Briney, n.d.). The primary generating forces are wind and differences in water density caused by variations in temperature and salinity. Currents generated by these forces are modified by factors such as the depth of the water, ocean floor topography and deflection by the rotation of the Earth. Horizontal currents are wind driven, fast moving and carries small amount of water; while, vertical currents are slow moving, density driven and carries large bodies of water....

- Private Temptation and Social Restraint in Measure for Measure In his play, Measure for Measure, Shakespeare poses problems of law, justice, and personal freedom for which he offers no easy answers. Measure for Measure is very relevant to current political debates over public morality and the limits of self-expression. The play proposes the question: How do we reconcile social restraint and personal passion. The Vienna of Measure for Measure, under the rule of Duke Vincentio, is a garden gone to seed....

- William Shakespeare's Measure for Measure The desires of the characters in Shakespeare’s Measure For Measure are not entirely clear, and are made ambivalent and ambiguous by the use of their language. Particularly in 3.1.52-153, when Isabella visits Claudio in prison, ambiguous lines and puns make it unclear whether Isabella desires Claudio’s death and whether he truly desires to be free of sin. These desires were further convoluted by viewing the current Folger Theatre production of the play.... [tags: Shakespeare measure for Essays]

- Morality in Measure for Measure Shakespeare's play, Measure for Measure, focuses on human morality. The play also explores the question of what kind of sexual conduct is socially acceptable, and what is not. The play depicts various attitudes toward prostitution, promiscuity, and premarital sex. But it also suggests that human laws and perhaps human morality are quite arbitrary and relative. Measure for Measure considers the need for statutes and laws to govern sexual appetites and ensure domestic tranquility.... [tags: Measure for Measure]

- Abstinence and Orgy in Measure for Measure Many existing views of Measure for Measure seem intriguing but incomplete. They might reinforce our perception of this play as fragmented and baffling, because they do not integrate apparently conflicting outlooks presented in the play’s Vienna, and generated by the mysterious action of Vincentio. Notice how the following different interpretations display the conflicts: the extreme view proposed by Roy Battenhouse that the Duke stands for God (Rossiter 108-28); the modified position of Elizabeth Marie Pope that the Duke is a successful magistrate with divinely-delegated powers ("Renaissance" 66-82), almost in line with Eliade’s version of...

- Exploring Morality in Measure for Measure In Measure for Measure, Shakespeare is able to examine the concept of right and wrong through the characters of Mistress Overdone and Mariana. Throughout the play, by using characters that most people would find morally reprehensible, Shakespeare is able to give the audience a different view of these people and, hopefully, show his audience that people aren't always what they appear to be. Through the character of Mistress Overdone, Shakespeare is able to bring a jovial side to the oldest job known to man -- prostitution.... [tags: Measure for Measure]

- Angelo in Measure for Measure Within Measure for Measure, the character of Angelo can be seen as a case study of will over moral nature. Angelo, a deputy, is given the Dukes authority to act in his behalf while the Duke is away. The story unfolds as Angelo uses the agency he's been given in ways that many men in authoritative positions have done. It is interesting to follow his line of thought and to realize that this is a man who is not unlike many others. The main conflict between Isabella and Angelo is a contemporary problem....

- The Good and Evil Angelo of Measure for Measure In Shakespeare's Measure for Measure, Angelo emerges as a double-sided character. Scholars have argued for centuries whether or not Angelo is a moral character or an evil character. Those scholars who support the notion of Angelo as moral often cite the following facts: the Duke obviously trusts Angelo, Angelo is disheartened enough by the end of the play to offer a sincere apology, and Angelo tries to resist the temptation that Isabella presents. On the other hand, others have argued that Shakespeare depicts Angelo as a purely evil man. These critics emphasize Angelo's treatment of Marian, the Duke's possible suspicion...

- The Virtuous Isabella in Measure for Measure Measure for Measure is not a celebration of family values, the play points towards both the political virtuosity, which sustains the comic, and the humbler self-knowledge that preserves the integrity of the virtuoso. Human virtue can only be chosen in freedom, but we need not deny ourselves the opportunity of ensuring that this choice is not stifled by the subtly related powers of abstract intellectualism and carnal necessity Isabella in Measure for Measure personifies innocent virtue....

- Immorality and Corruption in Measure for Measure In ‘Measure for Measure’, Shakespeare demonstrates that there is an innate immorality and corruption in the heart of man. Shakespeare illustrates that power does not cause corruption. This is achieved by presenting the Duke, who has the most power in Vienna, as a moral hero, and conversely revealing the corruption of the powerless class through characters including Pompey, Mistress Overdone, and Barnadine. Through all this, Shakespeare uses Lord Angelo in Measure for Measure to show that immorality and corruption is innate in mankind.... [tags: Measure for Measure]
