Mobile Hotspots for Ocean Sensors & AUVs
Monterey Bay Aquarium Research Institute (MBARI)
The Monterey Bay Aquarium Research Institute (MBARI) is a leader in applying technology to longstanding problems in ocean science. As their collection of ocean vehicles and robots grew, they faced a new challenge: how to improve coordination and communication between surface and subsea vehicles and access to data from these systems in real-time. One solution? A new hotspot payload for the Wave Glider.
Monitoring Water Quality in the Gulf of Mexico After Hurricane Harvey
Texas A&M University, Geochemical and Environmental Research Group
As 13 trillion gallons of floodwater flowed into the Gulf of Mexico after Hurricane Harvey, researchers from Texas A&M’s Geochemical and Environmental Research Group (GERG) needed an efficient way to monitor water quality and understand the impacts to the ecosystem. And they needed to move quickly.

Tracking Crabs in Real-Time to Improve Fishery Management
Ocean Tracking Network at Dalhousie University (OTN)
Snow crabs play an important role in Nova Scotia’s ecosystems. But traditional tagging methods for these mobile undersea animals relied on static receivers on the ocean floor, and weren’t always effective. The Ocean Tracking Network (OTN) needed a better way to track individually tagged crabs and understand their movements and patterns, even when they were not moving past a receiver line.
On-Demand Marine Water Sampling
Centre for Environment, Fisheries and Aquaculture Science (Cefas), UK
Cefas needed a way to track and sample algal blooms in the right place at the right time. If they could confirm the presence of the Karenia sp. dinoflagellate within an algal bloom, then they could help improve the satellite algorithms used in the production of satellite products. Together we created a mobile, responsive solution for on-demand autonomous water sampling.
