This activity proposes different small experiments and discussions to show that in the summer it is cooler by the sea than on the land and that water cools off more slowly than soil.
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.
Introduction to Oceanography is a textbook appropriate to an introductory-level university course in oceanography. The book covers the fundamental geological, chemical, physical and biological processes in the ocean, with an emphasis on the North Atlantic region.
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.
Maneuvering motions of surface and underwater vehicles. Derivation of equations of motion, hydrodynamic coefficients. Memory effects. Linear and nonlinear forms of the equations of motion. Control surfaces modeling and design. Engine, propulsor, and transmission systems modeling and simulation during maneuvering. Stability of motion. Principles of multivariable automatic control. Optimal control, Kalman filtering, loop transfer recovery. Term project: applications chosen from autopilots for surface vehicles; towing in open seas; remotely operated vehicles.
The marine environment is unique and because little light penetrates under water, technologies that use sound are required to gather information. The seafloor is characterized using underwater sound and acoustical systems. Current technological innovations enable scientists to further understand and apply information about animal locations and habitat. Remote sensing and exploration with underwater vehicles enables researchers to map and understand the sea floor. Similar technologies also aid in animal tracking, a method used within science and commercial industries. Through inquiry-based learning techniques, students learn the importance of habitat mapping and animal tracking.
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.
In this activity, students learn about ocean currents and the difference between salt and fresh water. They use colored ice cubes to see how cold and warm water mix and how this mixing causes currents. Also, students learn how surface currents occur due to wind streams. Lastly, they learn how fresh water floats on top of salt water, the difference between water in the ocean and fresh water throughout the planet, and how engineers are involved in the design of ocean water systems for human use.
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.
A Student’s Guide to Tropical Marine Biology is written entirely by students enrolled in the Keene State College Tropical Marine Biology course taught by Dr. Karen Cangialosi. Our goal was to investigate three main aspects of tropical marine biology: understanding the system, identifying problems, and evaluating solutions. Each of the sections contains chapters that utilize openly licensed material and images, and are rich with hyperlinks to other sources. Some of the most pressing tropical marine ecosystem issues are broken up into five sections: Coral Reefs and Diversity, Common Fishes to the Coral Reef, Environmental Threats, Reef Conservation, and Major Marine Phyla. These sections are not mutually exclusive; repetition in some content between chapters is intentional as we expect that users may not read the whole book. This work represents a unique collaborative process with many students across semesters authoring and editing, and therefore reflects the interests and intentions of a broad range of students, not one person’s ideas. This collaboration began with contributions from KSC students in the 2017 semester and includes work from the 2019 class, as well as new content and editorial work from 2017 & 2019 alumni. We look forward to future editions of this book. Enjoy exploring the rainforests of the sea through our collaborative project and please share with those who care!

Students use a table-top-sized tsunami generator to observe the formation and devastation of a tsunami. They see how a tsunami moves across the ocean and what happens when it reaches the continental shelf. Students make villages of model houses and buildings to test how different material types are impacted by the huge waves. They further discuss how engineers design buildings to survive tsunamis. Much of this activity setup is the same as for the Mini-Landscape activity in Lesson 4 of the Natural Disasters unit.
