Departmental Seminar: A departmental seminary which is aimed to introduce an updated situation report of research areas by discussing articles from all disciplines of marine biology. Some of the subjects that will be discussed are: Global warming causes and effects, ocean acidification and its impact on flora and fauna, biogeochemical cycles, ecology and evolution, marine viruses and biotechnological developing from marine systems. An interdisciplinary discussion will occur after each lecture. The seminar will function as a workshop for presentation preparing in which a reciprocal feedback will be given.
The research student forum is a seminar course which aims to increase the exposure of graduate students to cutting edge research in biology, provide them with tools to critically read research papers, and train them in analyzing and presenting scientific data.
Every student will give two presentations during the course, one in-depth seminar talk (30 minutes) and one short conference-like talk (15 minutes). In each talk a student will present a recent paper published in one of the leading, high-impact journals, including the relevant background to put the paper into context. The papers will be chosen by the student in consultation with the teachers, and sent to the rest of the class minimum 5 days before the lesson. A list of high impact papers recommended by the teachers will be available for the students to pick from. The presentations will be followed by a discussion on both the paper itself and the manner in which it was presented. The students will send a list of papers they read to prepare their presentations to the teachers, and include it as a final slide in their talks. 80% attendance in the classes is required for completion of the course.
Grading is based on the presentations and participation in discussions:
40%- in-depth paper presentation: focus, clarity and speaker proficiency in: question addressed by the paper, background, methods used, results and their meaning, interpretation and discussion of the results and significance of the work.
40% - short conference-like presentation: focus, clarity and speaker proficiency in: Scientific question, background, approach, results, discussion and significance of the work.

The course physical oceanography aims to teach advanced students about the physical properties of ocean water and the physical processes within them, emphasizing the physical aspects that influence marine organisms. The course will discuss external (e.g., sun and winds) and internal (e.g., temperature and density) factors that drive physical processes in the ocean (currents, waves, stratification, ect.). Common mathematical formalism used to study these processes and get predictions will be introduced and practiced. The course will also describe the connection between physical factors and processes to biological processes and ecological systems.

The Mediterranean A: "The Mediterranean" course will discuss current topics relating to the Mediterranean, from natural sciences, social sciences and policy. The course will be divided into two semesters. During the first semester we will discuss the geology, geochemistry, oceanography, history and archeology of the Mediterranean. At the second semester we will focus on in-depth discussions of various aspects of pelagic, benthic and coastal ecosystems. We will end with a future outlook on the major challenges facing the Mediterranean, including sustainable fisheries, gas and oil exploration, desalination and other developmental programs. Each lecture will be given by an expert in the field, and will be accompanied by required reading material.
In addition to the lectures, the course will include three one-day field trips.
The course will be graded by two written projects ("home tests"), one for each semester, based on the material learned in the class. Participation in the lectures is mandatory.
Geochemical Oceanography::This course will focus on two major aspects: chemical cycles in sea water and geochemical processes in marine sediment, especially the interaction between sea water and the sediment. Main concepts of interactions and processes, fluxes and reservoir, sources and sinks in marine environment, will be discussed. The course chapters will include understanding of chemical composition and properties of water, dynamic equilibrium in the sea water, dissolved gases in water, resistance time and mass balance of several elements. In addition, transportation of dissolved and particle mater from land to sea, distribution and composition of marine sediment precipitation and dissolving, digenesis and subsidence of sediments will be discussed. We shell study about chemical and geochemical processes in sediment, bioturbation, redox processes, and processes in the intermediate sediment-water such as interaction between volcanic rocks and sea water. Final grade will be composed of an exam and tutorials.}Geochemical Oceanography

Marine Microbial Ecology::Microorganisms are the most dominant life form in marine environment and they function in key positions in marine food web and in global geochemical cycles. This course will deal with marine microorganisms – Bacteria, Archaea, Protists and Viruses – from biological point of view, and will discuss their adaptations to life in sea, the diverse interactions among them and the way the microbial population in sea influence life on earth. Some of the subjects that will be included in the course are: physical conditions of microbial world (diffusion, motion and meeting rates in viscous world), phytoplankton as an example of minimal organism, different life strategies of heterotrophic organisms, phages and their complex interactions with their host, eukaryotes' algae in the changing world, interactions between microorganisms and corals, dynamic models of microorganisms distribution etc.
From genes to oceans: Bioinformatics approaches in Marine Biology::Modern microbial oceanography relies heavily on the analysis of genes and proteins from marine organisms to help understand how these organisms adapt to life in the marine environment. Students will learn the basic concepts, approaches and tools used for bioinformatic analysis of sequence data, and will utilize these tools to analyze genomic and metagenomic data from the oceans. Students will also critically assess the current literature describing genomic, metagenomic and proteomic analyses from the marine environment. We will discuss how microbial genomes are built, and what shapes them in the marine environment; how are genes lost and gained through lateral transfer; viruses and their role in genomic evolution, and how the gene content of different environments can teach us about the selection pressure in that environment. Technical topics covered will include: Selection pressure on DNA, RNA and proteins, genomic architecture, sequence alignment, gene identification and phylogenetic assessment, sequencing and assembly methods, comparative metagenomics and proteomics. The course will include lectures, hands-on computer tutorial and student seminars. The final grade will be composed of 30% seminar and 70% final project.
Topic: the rocky shore is an extreme and fascinating environment that for several decades serves as a test-bed for experimental ecological research and for the development of ecological theory. This course reviews in detail the history, theory and methods of research in this ecosystem and uses hands-on experience to examine several major topics. Among the topics we will discuss are:
The Israeli Mediterranean perspective: During the course we will pay special attention to the unique rocky shore ecosystem on the Israeli coast – the vermetid (abrasion) reefs – an ecosystem under an extinction threat. We will discuss recent findings on the ecology of this system from studies conducted in the last 3 years and the present research that is being held at IOLR. The students will participate in biodiversity surveys and will study basic analysis of biodiversity data. They will also conduct short experiments in the lab and possibly field, testing for example the predation rates of crabs and larval settlement variability of invasive mussels. The students will work in small groups on specific projects and will write a short report in a scientific paper format that will be part of the overall course mark.
Format: This is an intensive five-day course that will take place at the National Institute of Oceanography of IOLR in Shikmona, Haifa, and will include every day lectures intermittent with field sampling, lab work, data analysis and interpretation. Several scientific papers will be given to the students for reading prior and during the course (for writing of the reports).
The mark will be based on a final exam (50%), project report (40%) and general participation (10%).
The students must be equipped with basic clothing and gear for working in the marine environment
