The Southern Ocean, which surrounds Antarctica, is a key region in determining global climate. This video lecture presents data revealing that the Southern Ocean is undergoing an alarming warming trend that may affect climates in the Pacific, Atlantic, and Indian Oceans. What does the Antarctic region tell us about our future? Is Antarctica especially sensitive, so that now it serves as an early warning ... Full description.

Climate Watch is an audio series about Earth's atmosphere, climate change, and global warming organized around four areas: origins of climate, climate change, impacts of climate change, and action. Information is provided via the voices of scientists working in the atmospheric sciences. Full description.

This video lecture includes discussion of the physical properties of gases and demonstrates how air is liquefied. Liquefied gases are a key resource for survival with an amazing range of applications and there are now few industries which are not in some way dependent on this major raw material. Life-saving operations in hospitals, the purification of polluted rivers and lakes, and superconductivity ... Full description.

Biology operates at two levels: the large scale which we can see and the underlying microscopic one. This video lecture describes how intermolecular forces cause protein arrays to self-assemble, enabling nature to fabricate the large scale components of living systems. The lecturer explains how scale, forces and information cooperate to form complex structures. There are demonstrations of gravity, ... Full description.

This video lecture uses satellite-mounted instruments, ship surveys and computer modeling studies of the workings of the marine environment to explore oceanography and current fish supplies worldwide. There is discussion of the need for global farming strategies necessary to ensure that the oceans can continue to provide food. The lecture uses successive satellite images of algal blooms in oceans ... Full description.

This lecture explains research on the shark species who migrate north to Massachusetts as the ocean waters warm in May and June. Among the species are oceanic sharks such as the blue, mako or basking sharks; coastal species such as sandbar sharks, spiny and smooth dogfish; or tropical species such as tiger and hammerhead sharks; and the porbeagle shark, the only species found year-round in Massachusetts ...

In this lecture, an ecologist shares photos and video clips as he explains biological and geological changes he has observed at an undersea volcanic ridge 2,500 meters deep in the Pacific Ocean. The ongoing studies from 1991 of this unique natural deep-sea laboratory are dramatically altering views of the rates at which many biological and geological processes are occurring on the face of the planet. ... Full description.

In this lecture, a marine biologist shares her experience of exploring 3,000 feet below the ocean surface at the Galapagos Islands to identify a colorful array of rarely seen animals and plants, including more than a dozen previously unknown species. The speaker exposes the dynamics of evolution through stunning footage of these creatures; shares some of her personal stories and insights about the ... Full description.

This video lecture explores the chemistry of the hordes of molecules in the interstellar medium revealed by radioastronomical observations of our galaxy. Extremely fast reactions result in the high abundance of complex organic compounds in the space between the stars. The chemistry of the interstellar medium illustrates that complex synthesis occurs under totally abiotic conditions. The specific reactions ... Full description.

Natural history information on some of the organisms found on soft-bottoms mainly in the coasts of Washington. Good pictures and highlights on common invertebrates and plants species, with scientific names provided. Special emphasis on evolutionary adaptations of feeding and other interesting physiological issues. Information on sampling devices also included. Full description.
