A ll scientists face pressure to give external seminars and attend conferences. This is especially important for early-career researchers because doing so can help them to find new positions, and adds to their CVs. To do research effectively, scientists need to build networks and collaborations, and learn about cutting-edge developments in their field. But the benefits need to be weighed against the environmental costs of attending conferences and meetings 1. A return flight from London to New York (11,000 kilometres), for example, releases around 2 tonnes of carbon dioxide-roughly the same as that produced, on average, by a year's car usage in the European Union. Attending a conference generates an estimated 800 kilograms of CO 2 emissions per participant. From our experiences as junior and established faculty members in the biological COLUMN Celebrate sustainable travel at conferences Universities should reward green travel practices when they make careerdefining decisions, say Olivier Hamant, Timothy Saunders and Virgile Viasnoff. WAVEBREAK MEDIA LTD/ALAMY Travelling by train can reduce the environmental impact of attending a conference.

We introduce a video-based approach for producing water surface models. Recent advances in this field output high-quality results but require dedicated capturing devices and only work in limited conditions. In contrast, our method achieves a good tradeoff between the visual quality and the production cost: It automatically produces a visually plausible animation using a single viewpoint video as the input. Our approach is based on two discoveries: first, shape from shading (SFS) is adequate to capture the appearance and dynamic behavior of the example water; second, shallow water model can be used to estimate a velocity field that produces complex surface dynamics. We will provide qualitative evaluation of our method and demonstrate its good performance across a wide range of scenes.
