6 x Hydrophone Array

Seiche has been putting its recently developed 6xHydrophone Array into active service as part of a package with 3×120°TI/HD Camera Systems, plus PAM and Camera Operators. Our latest project commenced at the end of 2017 and ran for period of six months. Contracted by AIS, and working for Fugro, we undertook a Geophysical/Geotechnical survey utilising […]

Middelfart Listening Station

Middelfart is a marine protected area containing a high density of harbour porpoises. Seiche is working in partnership with Aarhus University and Naturpark Lillebaelt to provide real-time monitoring of porpoise activity and levels of ambient sound. The aim of the Listening Station is to help gain an understanding of why this area is important for […]

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 […]
