Water, Water Everywhere
Water is all around us, and its importance to nearly every natural process on earth cannot be underestimated. It is vital to life, but it is also tightly coupled to climate, helping to carry heat from the tropics to higher latitudes.

The Ocean Carbon Cycle
Students at Bigelow Laboratory gain an in-depth understanding of oceanography through hands-on research experiences in the lab and field. A group of students made this stop-motion animation that traces the ocean carbon cycle, following carbon from the atmosphere into a tuna sandwich.
