MBARI researchers head out into Monterey Bay to deploy a long-range autonomous underwater vehicle

MBARI Works at Unlocking Ocean Biology

Greater understanding of what goes on in the ocean is starting to become a reality – thanks to growing use of unmanned surface and underwater vehicles and developments in biological sensing.  Elaine Maslin takes a look at what a team at MBARI has been doing.Gathering biological data from the oceans remains a significant challenge for oceanographers. Now, an increasing range of unmanned vehicles that are able to work together is becoming available,

Electric Motor Selection for Underwater Vehicles: Considerations of Partial Load Efficiency

It is easy to appreciate why permanent magnet synchronous motors (PMSMs) are popular for use in underwater vehicles (UVs). They are compact and efficient with a high power density. More importantly, perhaps, they allow for effective operation across a broad RPM range which is beneficial for vehicles with multiple operating conditions. That said, we find vehicle product developers are often uncertain about a motor’s “efficiency”.

Deep-Sea Coral Gardens, Graveyards Discovered Off Australia

Bremer Canyon Marine Park is already known as a biodiversity hotspot for marine species such as whales and dolphins, however, a recent expedition focused on the deep sea has now revealed rich and diverse ecosystems inhabiting the cold waters deep within the canyon. Led by researchers from the University of Western Australia (UWA), these discoveries were only made possible by the philanthropic Schmidt Ocean Institute’s (SOI) deep-sea remotely operated vehicle,
