The Underwater Acoustics and Navigation lab (ANL), headed by Prof. Roee Diamant, is active in the fields of underwater acoustic communication networks, underwater signal detection, object classification, underwater localization, and underwater navigation. Our research interests include channel modeling, design of algorithms and protocols, analysis, and development of simulation tools. We focus on applied research and develop tools for problems like underwater mine detection, navigation without GPS, communication between divers and autonomous vehicles, classification and characterisation of marine mammals and fish, tracking the motion of marine animals, and long range acoustic communication. The facilities in the lab include equipment for sea experiments, a large acoustic chamber, and a direct access to perform measurements from the lab in a testing pool and in the Shikmona reef.

Localization and tracking of underwater objects
Concept and scope of our project: our underwater cybersecurity solution encompasses the authentication of network transmissions, signal interception countermeasures and LPD signal detection. Our solutions will be tested at sea in realistic scenarios involving multiple underwater communication devices:
Our research focuses on developing a remote sensing solution for predicting maintenance needs in ship machinery. We use underwater noise emitted by ships to remotely monitor their machinery without needing any onboard installations. By analyzing changes in the ship's acoustic signature, we aim to detect potential issues in the propulsion system, pumps, generators, and other equipment. This proactive approach helps prevent costly breakdowns and ensures the safety of both the vessel and its crew. Our process is fully automated, requiring no input or collaboration from the ship's crew, making it a convenient solution for busy operators.
Active acoustics for detection of sea turtles
AUV using SAS to detect a target object, such as a wreck or submerged mine, and then approaching to capture optical images for verifying the target by comparing it with the object in the SAS image, serving either for target verification or navigation aid.

Exciting News!
We’re proud to announce the launch of a new website in collaboration with Labust, offering unprecedented access to underwater noise data from over 1,500 vessels. Explore and compare sound pressure levels (SPL) and 1/3 octave noise data by vessel type, speed, and size. Get detailed insights into the acoustic impact of maritime traffic, with downloadable raw noise recordings and images of the vessels.
Discover the hidden world of underwater noise now!
In the late 1960s, scientists, including CETI’s principal advisor, Dr. Roger Payne, discovered that whales sing to one another. His groundbreaking recordings, Songs of the Humpback Whale, ignited the “Save the Whales” movement—one of the most successful conservation efforts in history. This campaign eventually led to the Marine Mammal Protection Act, which ended large-scale whaling and saved several whale populations from extinction.
All of this was achieved simply by listening to whale songs. Now, imagine what could happen if we could truly understand their communication.
The ANL has been part of the CETI project since 2021, focusing on developing technology to detect and analyze sperm whale acoustic data to decode their communication. Join us in this incredible collaboration that has the potential to change the world as we know it.
