What Greeneridge Sciences does

Greeneridge Sciences Inc. is an independent for-profit bioacoustic research firm founded in 1982 by Dr. Charles Greene in Santa Barbara, California. The company specializes in measuring, documenting, and mitigating human acoustic impacts on marine wildlife, with a particular focus on arctic and subarctic marine environments. Its work combines instrument design, field data collection, and signal analysis to support environmental compliance and scientific research for industrial, military, and academic clients.

The company's core product line is built around proprietary acoustic recording systems developed in-house. This includes the DASAR (Directional Autonomous Seafloor Acoustic Recorder), a DIFAR-based directional seafloor system; the ASAR (Autonomous Seafloor Acoustic Recorder), a broadband recorder deployable from 1.5 m to 300 m depths with up to 1 TB per deployment; the DAMS (Directional Animal Monitoring System) developed for U.S. Navy P-3 aircraft; DIFAR receivers and demultiplexers sold to customers; and the Acousonde acoustic tag (manufactured under the Acoustimetrics sub-brand) for animal-attached recording. Greeneridge also develops custom signal analysis software and DIFAR demultiplexing tools internally and for sale.

Greeneridge generates revenue through project-based professional services (instrument design, field deployment, analysis, and reporting) and direct sales of specialized acoustic recording equipment. It serves a diversified client base across oil and gas (BP Exploration Alaska, Shell Offshore, Hilcorp Energy), federal agencies (NOAA Fisheries, NMFS, SPAWAR, U.S. Navy), defense (Raytheon), mining (Baffinland Iron Mines), and academic institutions (Scripps, Cornell, Johns Hopkins, Purdue). The firm operates with a small team (1-10 employees) across offices in Santa Barbara, Santa Cruz, and San Diego, and conducts fieldwork in Alaska, Greenland, Canada, and elsewhere. It formally declared independence from LGL Limited in February 2018.

Core offering

Greeneridge Sciences sells custom-designed underwater acoustic recording instruments (DASAR, ASAR, DIFAR-based sonobuoy systems, DAMS, and Acousonde tags) and delivers bioacoustic research and monitoring services for marine wildlife. The company provides project-based professional services spanning instrument design, field deployment, data analysis, and reporting, focused on monitoring and mitigating human acoustic impacts on marine mammals in arctic, subarctic, and other marine environments.

Product overview

Greeneridge Sciences is a bioacoustic research company offering a portfolio of specialized acoustic monitoring products and services. The core product line includes the DASAR (Directional Autonomous Seafloor Acoustic Recorder) for long-term seafloor-based marine mammal monitoring, the ASAR (Autonomous Seafloor Acoustic Recorder) for broadband acoustic recording, and DIFAR-based systems for directional sonobuoy applications. The company also offers Acousonde acoustic tags (a brand under Acoustimetrics) for animal-attached recording. These products are complemented by custom-developed signal analysis software and are used for monitoring whale calls, assessing industrial noise impacts, and supporting environmental compliance for offshore developments.

Functional benefit

Brands

• Acoustimetrics: A brand of Greeneridge Sciences, Inc. that manufactures the Acousonde 3B, an acoustic tag that records sound as well as other parameters such as depth, acceleration, compass bearing, temperature, and light levels for marine wildlife research.

Products and services

• DASAR (Directional Autonomous Seafloor Acoustic Recorder) DIFAR-based instrument combining a directional sonobuoy hydrophone package with a battery-powered digital recorder for long-term unattended monitoring of both temporal and spatial characteristics of marine mammal vocalizations; DASAR array yields position estimates with average 90%-confidence errors between 250 m and 1 km for calling whales.
• ASAR (Autonomous Seafloor Acoustic Recorder) Broadband acoustic recorder with broad frequency and dynamic ranges, deployable in water depths from 1.5 m in bottom-mounted configuration to 300 m in acoustic release/mid-water column configuration; capable of recording 1 TB of two-channel acoustic data in a single deployment.
• DIFAR-based Systems Directional sonobuoy systems including DIFAR receivers and demultiplexers designed by Greeneridge for internal use and sale to customers, used for detection and monitoring of marine mammal vocalizations.
• DAMS (Directional Animal Monitoring System) DIFAR-based system installed aboard military P-3 aircraft for the real-time detection and localization of marine mammal vocalizations during naval shock trials, supporting protected species mitigation monitoring.
• Acousonde acoustic tags (Acoustimetrics brand) Animal-attached acoustic recording tags produced under the Acoustimetrics brand of Greeneridge Sciences that record underwater sound along with depth, acceleration, compass bearing, temperature, and light levels for marine wildlife research and tracking.
• Bioacoustic Research and Monitoring Services Comprehensive project-based research services spanning instrument design, field deployment, acoustic data collection, signal analysis, and reporting for monitoring underwater sound and mitigating anthropogenic acoustic impacts on marine wildlife in arctic, subarctic, and other marine environments; tailored for oil and gas, government, defense, academic, and industrial clients.

Quantifiable outcome

• DASAR localization accuracy: average 90%-confidence errors between 250m and 1km for calling whales

Broad incumbents

• EdgeTech: EdgeTech manufactures underwater acoustic instruments including side-scan sonars, sub-bottom profilers, and acoustic recorders — a larger incumbent with overlapping capabilities in seafloor acoustic recording that competes for similar government and academic research budgets.
• Brüel & Kjær (HBK): HBK (formerly Brüel & Kjær) is the global leader in acoustic measurement instrumentation with a marine hydrophone portfolio — a broad incumbent whose underwater products and expertise overlap with Greeneridge's instrumentation work, though HBK serves a much wider industrial customer base.
• LGL Limited: LGL Limited is a larger environmental research firm that was Greeneridge's parent organization until 2018. LGL offers broader ecological and environmental services across multiple species, with shared heritage in Alaska/Beaufort Sea marine mammal monitoring. Comparable in Arctic expertise but broader in scope.

Others

• Cornell Lab of Ornithology (Bioacoustics Research Program): Cornell's Bioacoustics Research Program develops acoustic monitoring tools and analysis software (Raven) used in wildlife bioacoustics — a research institution and Greeneridge customer that operates in adjacent acoustic monitoring science, though focused on terrestrial species.
