Welcome…

We are a world-leading marine technology company specialising in underwater acoustics. Our systems enable clients to comply with environmental regulations to protect marine life from the effects of sound in water. We provide expertise in Mitigation, Measurement and Modelling.

PrintStarted in 1996 to undertake underwater acoustics research projects, the company was involved in the early stages of Passive Acoustic Monitoring (PAM) development and is now the market leader in its field.

Seiche has a global reach via its offices in the UK, USA, Scandinavia and South Africa, and also maintains strong partnerships with industry, academics, and government agencies around the world.

In the recent Sunday Times Tech Track 100 Index, Seiche was placed as Number 1 manufacturer in the South West and Number 2 in the UK as a whole.

We are committed to supporting all our equipment in the field and provide 24/7 rapid response to all on-site queries.

Digital Thin Line Array

Seiche’s Digital Thin Line Array is a high-performance, low-noise acoustic array that provides highly sensitive passive acoustic monitoring. The array measures just 20 mm in diameter and houses 8 digital hydrophone sensors, but can be configure for up to 32. The topside electronics are contained within a compact, robust housing. Each hydrophone sensor incorporates a […]

AutoNaut USV for PAM with thin line digital or analogue array

The AutoNaut is a near silent vessel and therefore ideal for Passive Acoustic Monitoring (PAM). Equipped with a Seiche hydrophone array system, the PAMAutoNaut provides a revolutionary new technique for marine acoustic surveys. It resolves the issues of traditional monitoring methods by providing both mobility and high signal-to-noise ratio and can unobtrusively monitor marine mammals.  […]
