Seabed video and still images from the northern Weddell Sea and the western flanks of the Powell Basin
Research vessels equipped with fibre optic and copper-cored coaxial cables support the live onboard inspection of high-bandwidth marine data in real time. This allows for towed still-image and video sleds to be equipped with latest-generation higher-resolution digital camera systems and additional s...

Research vessels equipped with fibre optic and copper-cored coaxial cables support the live onboard inspection of high-bandwidth marine data in real time. This allows for towed still-image and video sleds to be equipped with latest-generation higher-resolution digital camera systems and additional sensors.

Still images of 26-megapixel resolution and HD (high-definition) quality video data were recorded throughout each deployment.
