Worldwide, Just 26% Of The Sea Bed Has Been Mapped At High Resolution,

due to cost and other constraints, 

but a team of scientists enlisted a few female sealions to help map the sea floor, they attached cameras and sensors to small pieces of neoprene that they glued to the sea lions’ backs, the lightweight video cameras are giving researchers a glimpse of previously unexplored areas of the sea floor off the south coast of Australia, the findings, published on 7 August in Frontiers in Marine Science, include detailed maps of the ocean floor created by combining videos captured by the animals with a machine-learning model, Angelakis and his colleague’s trialled a comparatively low-tech approach by enlisting the help of wild Australian sea lions (Neophoca cinerea), on completion of the project, team members were able to remove the sensors from the patches without damaging the sea lions’ fur, using sea-lion-mounted sensors is a “very nice way of getting high-resolution data from a hard-to-get-at place”, says Hall, I have to admit it is a great and unobtrusive way to gather much needed data, so grab a coffee and join the seal on a hunt for food and enjoy the ride!
