Ocean Robotics & Underwater Communications
Underwater Optical Communications
These Underwater Optical Communications provide a reconfigurable, long-range, optical modem-based underwater communication network. In particular, the network provides low power, low cost, and easy to deploy underwater optical communication system capable of being operated at long distances.
Under Ice Oil Spill Mapping Response System
Under Ice Oil Spill Mapping Response System is a plug-and-play sensor system designed for MBARI long-range AUVs (LRAUV) equipped with oceanographic sensors and sensors necessary for oil detection and mapping. The data that can be autonomously obtained is crucial to developing baseline data in the Arctic and quickly providing decision-makers information during environmental disasters to limit damages.
Nereid HT Hybrid ROV
Nereid HT Hybrid ROV Inventors: Andrew Bowen Overview: Submersible vehicles use tethers to carry power and communicate, but these tethers can place a significant burden on vehicles as well as at-sea logistics, as undersea robotics reach greater depths. Removing dependence on traditional tethers and creating more versatile, lightweight hybrid ROVs/ AUVs reduces the on-board winch…
Multi-Carrier Underwater Acoustic Communications
The Multi-Carrier Underwater Acoustic Communication System uses a two-step approach to mitigate frequency-dependent Doppler drifts for zero-padded OFDM transmissions over fast-varying channels. The system is based on block-by-block processing and does not rely on channel dependence across OFDM blocks. Thus, the system is applicable for fast-varying UWA channels.
Long Range Fiber Optic Data Communications
The system includes a cabled ocean observatory deployed underwater and connected to a surface buoy. The fiber optic extension modules can be permanently attached to each end of the fiber optic cables and include an optical transceiver, a power supply, and an inductive element for removably coupling an underwater sensor or the cabled ocean observatory to the fiber optic cable.
Doppler Shift Navigation
Swarm intelligence is a collective behavior composed of many individuals that coordinate using decentralized control and self-organization – typically used in aircrafts and drones because of the access to GPS, high data rates, and low-cost hardware. Integration into underwater swarming intelligence has been stagnant due to limited access to GPS, Wi-Fi, expensive navigation, and low data rate communications. WHOI scientists and engineers developed a family of innovations to generate successful underwater swarming capabilities.
AUV SUPR Sampler
The system employs the highly adaptive REMUS vehicle to autonomously navigate a programmed trajectory through the water column and rapidly capture discrete samples of microorganisms and particles using a modifiable filtration mechanism.
