The course treats the following topics: - Relevant physical oceanography - Elements of marine geology (seafloor topography, acoustical properties of sediments and rocks) - Underwater sound propagation (ray acoustics, ocean noise) - Interaction of sound with the seafloor (reflection, scattering) - Principles of sonar (beamforming) - Underwater acoustic mapping systems (single beam echo sounding, multi-beam echo sounding, sidescan sonar) - Data analysis (refraction corrections, digital terrain modelling) - Applications (hydrographic survey planning and navigation, coastal engineering) - Current and future developments.
This graduate course will introduce students to the processes controlling phytoplankton, zooplankton, heterotrophic bacterial and benthic infaunal growth and abundance. We'll do a broad-scale survey of patterns of productivity and abundance in the coastal zones, upwelling centers, gyres, and the deep sea. We'll briefly survey ecosystem simulation models, especially those applicable to the Gulf of Maine. Readings will be from the primary literature and a few book chapters. The effects of anthropogenic effects on marine communities will be stressed throughout. Calculus will be used throughout the course, but there is no formal calculus requirement.
Wave equations for fluid and visco-elastic media. Wave-theory formulations of acoustic source radiation and seismo-acoustic propagation in stratified ocean waveguides. Wavenumber Integration and Normal Mode methods for propagation in plane-stratified media. Seismo-Acoustic modeling of seabeds and ice covers. Seismic interface and surface waves in a stratified seabed. Parabolic Equation and Coupled Mode approaches to propagation in range-dependent ocean waveguides. Numerical modeling of target scattering and reverberation clutter in ocean waveguides. Ocean ambient noise modeling. Students develop propagation models using all the numerical approaches relevant to state-of-the-art acoustic research.
Evolution of Physical Oceanography was created to mark the career of Henry M. Stommel, the leading physical oceanographer of the 20th Century and a longtime MIT faculty member. The authors of the different chapters were asked to describe the evolution of their subject over the history of physical oceanography, and to provide a survey of the state-of-the-art of their subject as of 1980. Many of the chapters in this textbook are still up-to-date descriptions of active scientific fields, and all of them are important historical records. This textbook is made available courtesy of The MIT Press.
This course is an introduction to the fundamental aspects of science and engineering necessary for exploring, observing, and utilizing the oceans. Hands-on projects focus on instrumentation in the marine environment and the design of ocean observatories for ocean monitoring and exploration. Topics include acoustics, sound speed and refraction, sounds generated by ships and marine animals, sonar systems and their principles of operation, hydrostatic behavior of floating and submerged bodies geared towards ocean vehicle design, stability of ocean vessels, and the application of instrumentation and electronics in the marine environment. Students work with sensor systems and deploy them in the field to gather and analyze real world data.
Planet Earth’s ocean covers over seventy percent of its surface, yet oceanographic research has only recently come to its full potential with the advent of new technologies. This course in Introductory Oceanography emphasizes the need to understand geologic, chemical, physical, and biologic processes or features that occur in ocean environments. It is designed to be thorough enough to prepare you for more advance work, while presenting the concepts to non-majors in a way that is meaningful and not overwhelming.Login: guest_oclPassword: ocl
This book is written for upper-division undergraduates and new graduate students in meteorology, ocean engineering, and oceanography. After reading this book, it expected that students will be able to describe physical processes influencing the ocean and coastal regions: the interaction of the ocean with the atmosphere, and the distribution of oceanic winds, currents, heat fluxes, and water masses.
Oceanography will present the ocean in an historical and geographical context.We will examine physical and exploration ocean science in a holistic manner. Origins and evolution of the oceans will be examined scientifically, philosophically and historically. We will integrate spatial and temporal aspects of marine environments.

Optimal control, Kalman filtering, loop transfer recovery. Term project: applications chosen from autopilots for surface vehicles; towing in open seas; remotely operated vehicles.
Provides an understanding of the distribution of organic carbon (OC) in marine sediments from a global and molecular-level perspective. Surveys the mineralization and preservation of OC in the water column and within anoxic and oxic marine sediments. Topics include: OC composition, reactivity and budgets within, and fluxes through, major reservoirs; microbial recycling pathways for OC; models for OC degradation and preservation; role of anoxia in OC burial; relationships between dissolved and particulate (sinking and suspended) OC; methods for characterization of sedimentary organic matter; application of biological markers as tools in oceanography. Both structural and isotopic aspects are covered.
The Ocean Health Index is a new, comprehensive measure of the ocean’s overall condition – one that treats people and nature as integrated parts of a healthy system. The ocean touches nearly every aspect of our lives – making it essential to the economic, social, and ecological well-being of everyone, everywhere. Evaluated globally and by country, the Ocean Health Index presents 10 public goals that represent the wide range of benefits that a healthy ocean provides to people. Each country’s overall score is the average of its 10 goal scores. Overall scores and individual goal scores are directly comparable between all countries. All scores range from 0 to 100.
This course introduces theoretical and practical principles of design of oceanographic sensor systems. Topics include: transducer characteristics for acoustic, current, temperature, pressure, electric, magnetic, gravity, salinity, velocity, heat flow, and optical devices; limitations on these devices imposed by ocean environments; signal conditioning and recording; noise, sensitivity, and sampling limitations; and standards. Lectures by experts cover the principles of state-of-the-art systems being used in physical oceanography, geophysics, submersibles, acoustics. For lab work, day cruises in local waters allow students to prepare, deploy and analyze observations from standard oceanographic instruments.
Examines the intellectual foundations of the new discipline of deep sea archaeology, a convergence of oceanography, archaeology, and engineering. How best are robots and submarines employed for archaeological work? How do new technologies change operations plans, research designs, and archaeological questions? Covers oceanography, history and technology of underwater vehicles, search strategies, technology development, archaeological technique, sociology of scientific knowledge. Case studies of deep-sea projects include the wrecks of the Titanic and Monitor, Roman trading vessels in the Mediterranean, and deep research in the Black Sea.
Word table that includes a selection of OERs that deal with the field of oceanography, including fluid mechanics, physical oceanography, marine law and policy, and geophysics.
