the students are required a basic knoledge of algebra, calculus and Physics (dynamics and thermodynamics)
The course will describe the characteristics of water masses and the basic instrumentation and methods used for observing the oceans, basic concepts on energy and mass budgets (with a focus on marginal seas), processes involved in air sea interactions and how to describe them, basic dynamical balances in the oceaans, waves and currents in the coastal zone, sea level variations, vertical structure of the water column. The concepts are applied to describe the circulation of the Mediterranean, Baltic and Black Seas. The course will also teach techniques for data visualization based on the Ocean Data View software.
The students will acquire a basic knowledge of the processes leading to changes of temperature, salinity and producing currents and waves in the oceans. Description will focus on processes occurring in the coastal zone and on mass, energy and salinity balances in marginal seas and having important effects in the corresponding environments. The students will acquire capability of understanding the basic physical-mathematical language used in physical oceanograpphy. Moreover, the students will learn about basic techniques for presenting (also graphically) oceanographic data.
teaching will be based on a sequence of lectures explaining the content of the course. It will be integrated with exercizes (solution of simple problems) and demonstrations of techniques to plot oceanigraphic variables
The standard exam consists of 2-3 questions, asking you to describe a figure, to describe a process, a phenomenon or the characteristics of a basin, to comment a formula and its use, To describe a measurement device and/or procedure, to describe how some given data are obtained (up to 30 points)
The standard exam can be replaced by two written partial tests to be held during the course. The test includes a) 4 or 5 questions with multiple choices where to mark the correct answer/statement and b) 4 or 5 questions requiring an explicit explanation. The score attribute to both part a) and b) is 15. No penalty for wrong answers. Minimum score in the first test for accessing the second test is 15. The final score is the mean of the two tests. The time for the test is 3 hours.
For both types of exams , the score can be integrated with a short report based on a) the ODV software and the plot of oceanographic data OR b) a summary/report of a relevant scientific paper. The content of the report will be discussed during a short interview (up to 4 points)
During the emergency to face the COVID-19 epidemic, the exam will be carried out using the "Microsoft TEAMS" platform (instructions for students available on https://www.unisalento.it/lezioni-online).
