  • Ecologist Natalie Boelman is headed back to the far north to study birds—this time to the town of Slave Lake, in northern Alberta, Canada, to track the migration of American robins. She will have some schoolchildren in New York remotely helping her as she and her colleagues get to work.

  • Vicki Ferrini has spent a lot of time working on mapping the ocean floor. Now, she's out on the ocean exploring life around hydrothermal vent systems 2,400 meters beneath the surface of the South Pacific.

  • Over the past decade, Elise Rumpf has studied lava flows on four continents and four planets, but she's never studied submarine flows until now. These are harsh environments where humans cannot survive unassisted, so we send machines to do the work for us. Rumpf describes those machines and their work from aboard a ship in the Atlantic.

  • The Indian Ocean’s warm, salty water has been leaking into the Atlantic, spinning off giant eddies with the help of the twisting Agulhas Current. Studies suggest that in the past, this warm-water leakage may have changed the strength of the ocean conveyor circulation, influencing historic climate changes. Follow Sidney Hemming and Allison Franzese’s experiences aboard the R/V Joides Resolution as they collect evidence to analyze the Agulhas Current’s behavior over the past 5 million years.

  • The barrenness of life and other particulate material in the clear waters of the central South Pacific allows light to penetrate more deeply than anywhere else. Columbia graduate students Frankie Pavia and Sebastian Vivancos are part of an international team of scientists studying the chemistry and biology of the South Pacific on the FS Sonne. They will try to determine input and removal rates of metals and trace elements from the ocean, which are crucial to our understanding of ocean life and past climates.
