Teledyne Webb Research Incorporates JASCO-made OceanObservers on Slocum Gliders


APRIL 26, 2021 – NORTH FALMOUTH, MA – Teledyne Marine is pleased to announce the availability of the JASCO-made OceanObserver™ system on Teledyne Webb Research's Slocum Glider Autonomous Vehicles. This latest addition to the Slocum Glider sensor suite adds key capabilities to the already versatile Slocum Glider platform.

OceanObserver™ is an intelligent passive-acoustic, multi-sensor system capable of in-situ, near-real-time underwater sound detection and measurements. The Observer records the underwater sounds and detects marine mammal calls from species of interest, quantifies ambient and anthropogenic noise, and derives other information of interest.  Acoustic detections and measurements are sent to stakeholders in near-real-time.

Slocum Gliders outfitted with OceanObservers and CTDs can also provide in-situ measurements of sound velocity profiles and ambient noise. Together, CTD and ambient measurements improve sonar sensor performance prediction and vulnerability assessment. The combined system is capable of monitoring in any sea state over extended periods of time.

Recent sales include universities and navies.  OceanObservers are being used by academics to support marine mammal science and mitigation measures, autonomous vehicle navigation research and the development of new detection, classification and localization techniques.  Naval customers are using Slocum's for marine mammal mitigation and measuring Sound Velocity Profiles & ambient noise variability over long deployment periods. Ocean ambient noise is affected by weather, waves, and shipping traffic.

The Slocum glider is buoyancy driven to enable long range and duration remote water column observation for academic, military, and commercial applications. The Slocum Glider can be deployed and recovered from any size vessel with minimal time on station. Once the Slocum glider is deployed, it can easily be controlled from anywhere in the world through the use of web based piloting tools. This allows fleets of gliders to be operated remotely with minimal personnel and infrastructure.

Slocum gliders are modular, allowing for rapid sensor reconfiguration to respond to emergency conditions or situations. Over 40 sensors and other options are available to address a wide variety of ocean conditions and sampling requirements.

Teledyne Webb Research designs and manufactures scientific instruments for oceanographic research and monitoring with a focus on extended observations over both time and space. Teledyne Webb Research specializes in three areas of ocean instrumentation: Neutrally buoyant, autonomous drifters and profilers (10,000 to date), autonomous underwater gliding vehicles (900 to date), and moored underwater sound sources. These systems are core to several major ocean monitoring programs including the international Argo array, the National Science Foundation Ocean Observatories Initiative and the U.S. Navy Littoral Battlespace Sensing – Glider (LBS-G) program of record. A Teledyne Webb Research Slocum glider, the Scarlet Knight, was the first unmanned vehicle to cross an ocean. To learn more, visit
