The Deepest Place on Earth

The discovery of the Marianas trench was one of the first puzzle pieces that lead to the understanding of the most massive process that shapes the geology of the Earth; plate tectonics and the creation of new crust in the mid-ocean ridges and its subduction under the continents.

The unique geological conditions that make Krakatoa and its successor, Anak Krakatau, extraordinarily explosive and, despite its remoteness, dangerous are explained.

Loch Ness

Scotland is a ground zero for some of the most significant geologic cataclysms in Earth's history. Understanding of these titanic shifts was prompted by a mysterious lake known as Loch Ness.

New York

The geological history of New York City is as superlative as it's current economic impact including; a titanic mountain rage, massive volcanic eruptions, immense glaciers and an enormous flash flood.

Driest Place on Earth

Chile's Atacama Desert is the driest, oldest and deadest desert on earth. Yet it's plays host to living creatures and penguins even thrive nearby. It may provide clues to where to look for life on other, seemingly barren, planets.

Great Lakes

The Great Lakes region provided geologists with much of the evidence for the frequent ice ages that visited North America. But the lakes may be a rather transient feature of the continent dependent upon the recurring ice ages to maintain their existence.

A tsunami is a dramatic indicator of geological activity magnifying the impact into extensive coastal destruction. Scientists searching for evidence of past tsunamis to predict when they are likely to recur and how severe they are likely to be uncover a new phenomenon, the mega-tsunami.

The confluence of two geological forces created and continues to build the island of Iceland. They also keep the geology active with global implications. For now the massive, but retreating, glaciers are keeping the glaciers in check.

The Hawaiian Islands are a study in contradictions. The fastest growing islands on earth are also the fastest disappearing. Made of one of the hardest minerals, it crumbles at a touch. The world's most active volcano is nowhere near the typical volcanic regions. Geologists strive to understand these mysteries.

The Alps are known as the majestic mountain range of Europe. But their formation from a collision between Europe and Africa left an unstable structure that is now a classic study in erosion by rivers of water, ice and rock suggesting an even greater former glory. Left unexplained is why the Mediterranean Sea exists between the continents.

Mammals have adapted to live almost anywhere - from freezing polar regions, to the hottest deserts and from steaming jungles, to the world's vast oceans. They survive on a great variety of different foods and it's what they eat that so often determines their behaviour - and that of course, includes our own.

The Clean Room

To determine the true age of the Earth, geochemist Clair Patterson developed the uranium-lead dating method to make an unprecedented discovery - calculating Earth's age of 4.5 billion years. But Patterson's groundbreaking discoveries were just beginning. Patterson made it his mission to draw public attention to the detrimental effects of lead in the environment and dedicated his career to fighting against the petroleum and chemical industry, eventually achieving public health's biggest victory of the 20th century.
