The course for a round the world regatta leads the boats through the Mediterranean Sea and the Atlantic, Southern Indian and South Pacific Oceans. On their voyage, the skippers come across a large variety of oceanographic situations: strong currents, floating ice, wave formations of every kind and biological diversity. In this course the student will learn about the foundations of the science of oceanography. You'll learn about the classification and formation of the ocean floor, how current sea satellite analysis systems work, the chemistry of the oceans and the processes that led to its formation. To follow this course does not require previous knowledge of oceanography.

The world is facing unprecedented humanitarian needs. Today’s humanitarian crisis tend to be greater in number, often in urban settings, longer in duration and broader in regional impact. They generate human sufferings on a greater scale, disrupt essential services, such as water supply or sanitation and put health of large population at risk. Engineers and technical specialists in water, sanitation, energy, environment, and in other related fields play a vital role to respond to these challenges and growing needs. In the humanitarian sector, they are called the public health engineers and today they are increasingly needed! Why public health engineering matters so much in humanitarian crises? And how its related activities are carrying out in such complex environment? This is what this MOOC is all about! The EPFL, EAWAG-SANDEC and ICRC have decided to partner to guide you through this introduction to the fascinating field of public health engineering in humanitarian contexts.

How do solar cells work, why do we need, and how can we measure their efficiency? These are just some of the questions Introduction to solar cells tackles. Whether you are looking for general insight in this green technology or your ambition is to pursue a career in solar, “Introduction to Solar Cells” is an excellent starting point. The course is a tour through the fundamental disciplines including solar cell history, why we need solar energy, how solar cells produce power, and how they work. During the course we cover mono- and multi-crystalline solar cells, thin film solar cells, and new emerging technologies. The course includes hands-on exercises using virtual instruments, interviews with field experts, and a comprehensive collection of material on solar cells. At the end of the course you will have gained a fundamental understanding of the field. This will allow you to identify the most interesting or relevant aspects to be pursued in your future studies or in your professional career.

This course provides an overview of the issue of postharvest loss of grains by exploring essential physical, technical, and social dimensions of postharvest supply chains and loss prevention methods globally. Each year, estimates suggest that 1/3 of all food produced is lost or wasted, making postharvest loss a critical global food security and sustainability issue of today. Key knowledge areas are presented including: -An overview of postharvest loss -Supply chain activities such as harvesting, drying, and storage -Economics and markets -An introduction to the network of actors working in this field We face the immense challenge of feeding over 9 billion people by the year 2050. To meet these demands, yields will have to more than double using the same amount of natural resources. In recent years, postharvest loss has been recognized by major institutions including the US government, the United Nations, the CGIAR Research Consortium, and several others as a significant opportunity to impact food security and improve livelihoods. Despite this increased attention, a lack of knowledge, technical capacity, and resources remain obstacles for stakeholders worldwide to act on these issues. This course will, for the first time, provide you as professionals, practitioners, and students, with a comprehensive introduction to postharvest loss processes and begin building capacity for loss prevention worldwide.

Mountains 101­­ is a broad and integrated overview of the mountain world. This 12-lesson course covers an interdisciplinary field of study focusing on the physical, biological, and human dimensions of mountain places in Alberta, Canada, and around the world. Specifically, we'll study the geological origins of mountains, how they’re built-up and worn-down over time; we’ll learn about their importance for biodiversity and water cycles, globally and locally; we’ll explore their cultural significance to societies around the globe, and how that relationship has evolved over time; and we’ll learn how mountains are used, how they’re protected, and how today they’re experiencing rapid change in a warming climate. At the end of each lesson, Mountains 101 will also provide learners with some smart tricks -- Tech Tips -- to safely enjoy time in the high alpine environment: from how to pick the best footwear for hiking to making smart decisions in avalanche terrain. We’ll be delivering your online lessons from valley bottoms to mountaintops, from museums and labs, to alpine huts and other spectacular alpine sites, and we’ll do so with the help of a whole host of experts. We invite you to join us for this online adventure! The mountains are calling...

Journey of the Universe weaves together the discoveries of the evolutionary sciences together with humanities such as history, philosophy, art, and religion. This course draws on the Journey of the Universe Conversations, a series of 20 interviews with scientists and environmentalists. The first 10 interviews are with scientists and historians who deepen our understanding of the evolutionary process of universe, Earth, and humans. The second 10 interviews are with environmentalists, teachers, and artists who explore the connections between the universe story and the practices for a flourishing Earth community.

The central question of this course: “why study wood?” If “why study wood” is the question, one answer would be that it is the only raw material available to us that is truly renewable in human life span terms. Wood is as important to society today as it ever was, despite the development of many man-made substitute materials, changing resource availability, and the changing needs of society. Some items on the list of wood products stay the same (lumber, plywood and veneer for building construction, furniture, shipping pallets & crates and other containers & packaging materials, railroad ties, utility poles, chemical feed stocks, etc), but the list also keeps changing to meet new needs and challenges as the resource changes. In short, wood is a far more diverse, green, and renewable resource than you might have imagined. Join us to learn about the important role of wood in human history, civilization, and our future. By the end of the course, learners will be able to: - describe wood as a raw material and its critical importance to the world economy, and the lives of the people that make that economy work. - identify the projected trend for wood consumption to continue to grow in the coming years, despite the image of wood as a "low tech" material. - identify the ways in which wood's properties can lead to its efficient and sustainable use. -identify wood's positive role in boosting the world economy and ability to lead to unexpected vocations.

Learn about diverse and integrated markets for primary energy, and the essential considerations driving business leaders and policy makers in development of global energy resources.

This course will cover the agricultural and urban water quality issues in Florida, their bases, land and nutrient management strategies, and the science and policy behind the best management practices (BMPs). Students will learn to evaluate BMP research and analyze its role in determining practices and policies that protect water quality.
