The marine acoustic sensors market size has grown strongly in recent years. It will grow from $1.2 billion in 2024 to $1.3 billion in 2025 at a compound annual growth rate (CAGR) of 8.1%. The growth in the historic period can be attributed to the need for underwater surveillance, early navigation relied on acoustic signals for underwater mapping, acoustic sensors have been crucial in monitoring fish populations, acoustic sensors have been instrumental in offshore exploration, the need for reliable communication underwater.

The marine acoustic sensors market size is expected to see strong growth in the next few years. It will grow to $1.75 billion in 2029 at a compound annual growth rate (CAGR) of 7.7%. The growth in the forecast period can be attributed to growing demand for underwater surveillance, expansion of offshore wind farms, rising importance of oceanographic research, emergence of autonomous underwater vehicles (AUVs), increasing maritime traffic. Major trends in the forecast period include integration of artificial intelligence (AI) and machine learning (ML), integration of wireless communication, advancements in signal processing, miniaturization and integration and product innovation.

The marine acoustic sensor market is poised for growth driven by the increased demand for marine transport. Marine transport involves the movement of goods and passengers through waterways such as oceans, seas, rivers, and canals using various watercraft. The surge in demand for marine transport is fueled by the growing need for commodities, spurred by population expansion and urbanization, resulting in heightened trade volumes. Marine transport plays a crucial role in facilitating the deployment and maintenance of marine acoustic sensors by enabling the transportation of equipment to offshore locations and granting access to diverse marine environments for research and monitoring purposes. For instance, as reported by the United Nations Conference on Trade and Development (UNCTAD) in November 2022, global maritime trade experienced a 3.2% growth in 2021, reaching a total shipment volume of 11 billion tons. Additionally, maritime trade is forecasted to expand at an average annual rate of 2.1% from 2023 to 2027. Consequently, the increased demand for marine transport acts as a key driver for the growth of the marine acoustic sensor market.

Leading companies in the marine acoustic sensor market are placing emphasis on features such as passive acoustic monitoring (PAM) capability to enhance underwater surveillance and environmental monitoring effectiveness. Passive acoustic monitoring (PAM) involves the detection and analysis of underwater sound without actively transmitted signals. For instance, in March 2024, Jaia Robotics, Inc., in partnership with Marine Acoustics, Inc., launched JaiaBot-PAM, featuring passive acoustic monitoring functionality with broad-spectrum acoustic sensors operating from 2 Hz to 30 KHz. These sensors collect diverse data including conductivity, temperature, depth, bathymetry, bottom composition, current flow, wave height, and wave period. JaiaBot-PAM offers cost-effective and adaptable acoustic monitoring solutions suitable for defense, national security, offshore renewable energy, aquaculture, and other sectors.

In October 2022, General Oceans, a UK-based ocean technology company, acquired Tritech International to enhance its offerings by integrating Tritech's advanced underwater imaging and measurement technologies into its portfolio. This strategic acquisition strengthens General Oceans' ability to provide solutions for marine exploration and monitoring. Tritech International, also based in the UK, specializes in designing and producing acoustic sensors, sonars, video cameras, and mechanical tooling equipment, thus complementing General Oceans' capabilities in the marine acoustic sensor market.

The value of goods in this market includes related services sold by the creators of the goods.

The market value is defined as the revenues that enterprises gain from the sale of goods and/or services within the specified market and geography through sales, grants, or donations in terms of the currency (in USD, unless otherwise specified).

Marine acoustic sensors are devices utilized to detect and analyze underwater sound. They serve to identify various types of underwater sounds, including marine mammal vocalizations, ship noise, and underwater geological activity. These sensors play a critical role in marine research, offshore industries, and defense applications, providing essential data for understanding and monitoring the underwater environment.

The primary products within the realm of marine acoustic sensors include hydrophones, underwater transducers, acoustic towed arrays, and side-scan sonar. Hydrophones function as underwater microphones, detecting and converting sound waves into electrical signals. They find application in diverse fields such as mine countermeasures (MCM), intelligence surveillance and reconnaissance, identification (ID), and anti-submarine warfare (ASW). These sensors cater to various end-users, including original equipment manufacturers (OEMs) and the aftermarket.
