COURSES OFFERED 2017-2018 FALL SEMESTER
Biological Oceanography: Marine plants and animals. Energy fixation, growth and abundance of organisms. Seasonality of production.
Chemical Oceanography: Chemical properties of sea water, alkalinity, C, N, P and S cycles, oxic and anoxic environments, redox processes.
Geological and Geophysical Oceanography: Evolution of the earth and morphology; minerals, rocks and sediments, basics of echo-sounding, sub-bottom profiling and side-scanning sonar methods.
Physical Oceanography: Physical properties of sea water, oceanic circulation, waves, oceanographic processes in the Turkish Seas.
The seafloor as one of the largest habitats on Earth, origin and properties; organic matter and particle fluxes to seafloor, geochemical properties of sediments, marine sediment biogeochemistry, organic matter degradation pathways in sediments, C, N, P, O, S cycles at the seafloor, benthic fluxes and benthic-pelagic coupling, chemosynthesis-driven ecosystems, deep-sea hydrothermal vents and midocean ridges, cold seep habitats and mud volcanoes, in situ sensors and platforms for seafloor biogeochemistry, effects of global warming on benthic processes, seafloor mineral and hydrocarbon resources and potential ecological effects of their utilization.
This course is intended to serve as an introduction to R programming as well as statistical concepts and data analysis techniques relevant to students of marine sciences. The statistical topics of interest include descriptive statistics, probability and distributions, hypothesis testing for uni-variate, multivariate and categorical data-sets, regression, correlation and non-linear curve fitting. The R computational environment will be used to analyze oceanographic data sets through the numerical implementation of the methods learned in the lectures.
This course is intended to provide graduate students of marine sciences an introduction to general ecosystem theory and mathematical concepts about and quantitative representation of trophic relationships between organisms/populations/communities within marine food webs along with the command of a widely-adopted marine ecosystem modelling tool Ecopath with Ecosim (Christensen et al.,2005). The topics of interest include, but not limited to foraging arena theory, ecological network analysis, ecological indicators, and quantification of ecosystem maturity/health.
Principal physical and chemical properties of water and sea water; chemical composition of sea water; conservative/nonconservative and dissolved/ particulate components of sea water; source and sink terms; processes in the sea; nutrient and carbon cycles in the oceans; standard methods for chemical analysis of sea water.
Descriptive and quantitative aspects of earth as bio-geochemical system; fundamental study methods of equilibria; transport processes; chemical kinetics; biological processes; their application to carbon, sulfur, nitrogen, phosphorus and other elemental cycles; stability of bio-geochemical systems; nature of human perturbation of their dynamics.
Physical property fields, currents, waves and tides, general circulation of the oceans, T-S analysis, ocean-atmosphere interaction, oceanographic processes in the Turkish Seas.
Mathematical models of circulation, mass transport and propagation, finite difference techniques, grid systems, numerical consistency, stability and convergence, numerical diffusion, conservative advection schemes. Primitive equations, quasigeostrophic and shallow water models, solution techniques for ordinary and partial differential equations arising in the marine environment, operational models and data assimilation.
Sampling strategies for fisheries; determination of age, sex, maturity and fecundity; food and feeding of fishes; indices to assess the state of the populations; introduction to fish stock assessment; use of computer programs in fisheries sciences.
Introduction to marine phytoplankton. General characteristics, classification. Sampling techniques, fixation and preservation. Identification and enumeration. Size classes and contribution to productivity. Factors affecting phytoplankton growth. Distribution, blooming and grazing. Adaptation to pelagic life. Succession and associations. Interactions with other marine organisms.
