Seeking a bird’s-eye view of the ocean to gain new insights 

Many critical ocean processes occur, or are exposed at, the interface of the air and the ocean surface. Aerial sensing platforms can provide safe, inexpensive methods to observe these phenomena in great detail, with regularity, and on short notice. To advance access to this area, without adding more ships to the MBARI fleet, a team of scientists and engineers is perfecting how to use the rapidly developing technology of unmanned aerial vehicles (UAVs). 

UAVs will enable a wide variety of repeatable and low-cost science applications including repeatable surveys of animal counts and locations, thermal and color ocean-front tracking, harmful algal bloom detection and monitoring, kelp forest health, predation behavior, marine debris, distressed animal detection, and lost-vehicle recovery. This technology will also document MBARI at-sea operations for educational and outreach purposes.

MBARI’s UAV project team of engineers, scientists, operators, and communications experts, along with collaborators from the Monterey Bay Aquarium, academic organizations, and government agencies will investigate several of these uses in 2019. The team will also develop best-practices, safety guidelines, and the legal permitting needed to operate these new technologies responsibly from the shore and MBARI ships. 

To accommodate these preliminary trials, the team has procured a vertical take-off and landing UAV, with an interchangeable and customizable nose-cone to carry a number of different sensor payloads. These types of vehicles can view and collect data over an approximate flight time of 90 minutes at speeds up to 100 kilometers per hour, and then land on the back of a ship or return to shore. The UAV project team aims to show how these new low-cost aerial technologies will reveal processes at the air-sea interface in ways not previously possible.
