No requirements are foreseen to attend the course and practicals on board of the R/V PELAGIA. A diving licence is required to attend underwater SCUBA diving practicals.
The course will deal with the main techniques for studying the coastal marine environment also through scuba diving and from the sea surface, on board of the research vessel Pelagia.
The aim is to provide both theoretical and practical basic knowledge on the techniques of studying the marine environment also by means of a scientific diver or by sampling from sea surface on board of a research vessel.
The course will be run by theoretical lessons (3 credits, 24 hours) and practical exercises in the field (3 credits, 30 hours).
The achievement of the credits attributed to teaching is obtained through an oral presentation of how each student would carried out an experiment in the fields of marine biology and ecology. The students should follow the hypothetico-deductive method and use methodologies learned during the course in order to test their hypothesis. This will evaluate the learning outcomes acquired by the student. The presentation will be followed by a question time with direct interview with the teachers. Upon motivated request of the student, the oral presentation is completely replaced by a full oral exam. The final grade is expressed in thirtieths, with possible praise. To pass the exam it is necessary to obtain a minimum score of 18 points, equal to a grade of 18/30. If the exam is insufficient, or the final score is less than 18, the presentation must be repeated or replaced by a full oral exam based on the student will. Following a double failure to pass the presentation test (due to insufficiency or non-acceptance of the grade obtained), the exam can only be taken by interview with the teachers. The attribution of the final score will be taken into account: of the level of theoretical and practical knowledge acquired (50%); the ability to apply the acquired knowledge (30%); autonomy of judgment (10%); of communication skills (10%).
General: Physiological effects of immersion on humans. Diving equipment: breathing systems and the use of mixtures; protection systems and cold water diving; communication systems; transport systems; cave diving. Destructive sampling techniques: scratches, panels, sorbonne, nets, traps. Non-destructive sampling techniques: squares, transects, video and photographic surveys, visual-census. ROV (remotely operated vehicles). Underwater environmental volunteering projects. Transplant techniques. Use of sensors. Use of underwater lifting bag for marine litter removal and for displacement of heavy underwater equipment.
Details: Autonomous scuba diving, basic instrumentation for underwater research. Underwater activities in the various scientific disciplines: areas and specificities. Physical and chemical oceanography: currentometry, underwater optics, water sampling. Portable control units. Criteria of accessibility and specificity in the approach to submarine habitats. Geology: topography, clinometry, morphometry, sedimentology, ripple-marks, penetrometry. Portable underwater sonars.
Biology and ecology. Experimental design for field studies. Scientific immersion in the study of the pelagic environment and the benthos. Qualitative, quantitative, qualitative-quantitative surveys.

Possible case studies:
Installation of anti-jellyfish nets
Monitoring colonial invertebrates: a case study with 10x10, 20x20 squares, visual collection (picking up). Manipulative experiments
Posidonia: counting and measuring shoots and leaves, lepidocronology, epiphyte coverage.
