Just 50 miles (80 kilometers) offshore of Bermuda, an unusual meeting took place this fall—not of people, but of three underwater robotic vehicles called gliders. Two of the gliders are owned and operated by BIOS as part of the Mid-Atlantic Glider Initiative and Collaboration (MAGIC) program. These vehicles, named Anna and Minnie, are equipped with a variety of sensors that measure ocean properties including pressure, temperature, salinity, oxygen, chlorophyll, and nutrients. The gliders have been diving and climbing from between the sea surface and depths near 2,500 feet (900 meters), while tracing a bow-tie-shaped route continuously surveying a 12-square-mile (20-square-kilometer) patch of ocean for the last six months.

Researchers and students representing BIOS gathered in San Diego, California, in mid-February to participate in the biennial Ocean Sciences meeting. The flagship conference, held jointly by the Oceanography Society, the American Society of Limnology and Oceanography, and the American Geophysical Union, attracted nearly 5,000 scientists, managers, and educators from around the globe.

For decades, sea-going research vessels have been the backbone of observational oceanography, giving scientists mobile platforms to conduct a variety of open-ocean research for days, or even weeks, at a time. Oceanographic research continues to build off previous work and, at the same time, the scale of research questions has broadened. As a result, the desire for more frequent observations of the deep ocean has driven the development of new technologies to increase research capability and accessibility.
