How does Sentry know where it is? New smarts keep the autonomous vehicle on track

New software enables Sentry to course correct while using a map of the area to recognize where it is. These improvements will allow observations of seafloor changes from year to year to track phenomena such as volcanic activity.

Sargassum Serendipity

Joint Program Student Chase Pixa and DSL engineers designed a drifter to float on ocean currents to track sargassum, a seaweed that has proliferated in recent years in the Caribbean. Like other types of algae, sargassum blocks sunlight from reaching corals, and when it decays, it sucks up oxygen from the water, killing marine life.

When Will Antarctica's Ice Cliffs Come Crashing Down?

Assistant Scientist Catherine Walker studies the dynamics of ice on Earth and in the universe. The height of ice cliffs around the continent, and the predicted height they will reach before collapse, is important for sea-level rise models and assumptions for how high the seas will rise.

Navigating the Changing Arctic

The newly developed Polar Sentinel glider will have the ability to collect critical and scarce ice thickness measurements from the Arctic.

Alvin Completes Science Verification

The human occupied submersible Alvin recently returned from a science verification cruise where it was certified to a maximum depth of 6,500 meters (four miles).

Meet the Sentry Team: Justin Fujii

Justin Fujii has been with the Sentry Group for eleven years and is part of a team that adapts the vehicle to perform new tasks dreamed up by its scientific users.

Who is Alvin and What are Sea Trials?

The human occupied submersible Alvin recently performed test dives to increase its depth rating to 6,500 meters (four miles). This depth will put 99 percent of the ocean floor within reach for the deep sea science community.
