Teledyne Technologies Inc. has received a $10 million contract from the U.S. Naval Oceanographic Office to supply devices used to predict human influences on the ocean. The five-year contract was given to Teledyne Webb Research, in North Falmouth, Mass., for autonomous profiling explorer floats. Parent Teledyne Technologies is based in Thousand Oaks. The autonomous floats are used to measure temperature, salinity, dissolved oxygen and nutrient content at different ocean depths. That data is used to develop climate and weather prediction models and understand human influence on the ocean ecosystem. “We are proud to be the leading supplier of autonomous profiling floats, having delivered more than 8,000 systems since 1982,” said Teledyne Chief Executive Robert Mehrabian in a prepared statement. Shares closed down 57 cents, or a fraction of a percent, to $92.39 on the New York Stock Exchange.
