I developed my camera system, called the Medusa, jointly with a colleague down in Australia as a method of exploring the ocean unobtrusively. The critical thing was that we didn't use white light, which I believe has been scaring the animals away.

It's a little-appreciated fact that most of the animals in our ocean make light. I've spent most of my career studying this phenomenon called bioluminescence. I study it because I think understanding it is critical to understanding life in the ocean where most bioluminescence occurs.

Exploration is the engine that drives innovation. Innovation drives economic growth.

Exploration is the engine that drives innovation. Innovation drives economic growth. So let's all go exploring.

There is the GIS world that is largely managing authoritative data sources, supporting geocentric workflows like fixing roads, making cities more livable through better planning, environmental management, forest management, drilling in the right location for oil, managing assets and utilities.

Environmental problems cannot be resolved here the way they are resolved in other countries. I heard that 80 per cent of the environmental problems in the U.S. are solved in court. That can't happen here.

I think the environmental problem will be the number one item on the agenda of the 21st century... This is a problem that cannot be postponed.

Climate change is happening, and humans are significant contributors, and that raises some really important policy questions.
