Moray West Offshore Wind Project
Exciting News from Seiche: Partnering with Ocean Winds on the Moray West Offshore Wind Project!
We’re thrilled to share some great news: the first wind turbine has been installed at Moray West! It’s been an incredible journey for us, with months of hard work from our dedicated team. Together, we successfully monitored the installation of 62 monopiles for the offshore wind farm in the outer Moray Firth, Scotland.
But that’s not all – our involvement extended to comprehensive noise monitoring during installation. We meticulously analysed the data, providing detailed analysis and reporting every step of the way. This project truly reflects our dedication to long-term noise monitoring and our ability to tailor solutions to fit our clients’ needs.
Stay tuned for more updates as we uncover fascinating insights from the data collected during this project!

Greenland Listening Station
Seiche has collaborated with Dr. Outi Tervo of the Greenland Institute of Natural Resources and local stakeholders, to install an underwater acoustic observatory (or ‘Listening Station’) in western Greenland.
A hydrophone is cabled ashore to the Listening Station at Qaqqaliaq Lighthouse, near Qeqertarsuaq, Disko Island. This enables researchers to monitor the songs of bowhead whales, which breed in Disko Bay during the winter and spring. Bowhead whales sing elaborate, repetitive songs, probably as a reproductive display, and are known for biphonation or two-voiced vocalisation. Researchers will use passive acoustic monitoring (PAM) to gain insights into their seasonal occurrence and activity in the bay.
Qaqqaliaq Lighthouse is remote, unmanned and ice-bound for much of the year, so the hydrophone signal is transmitted from the lighthouse in real-time, via a 4G data link. The underwater soundscape can now be monitored continuously, from any location with internet access. Alongside the bowheads, the fascinating underwater soundscape of in Disko Bay features calving ice bergs, beluga whales and narwhals, fishing boats, and the long trills of male bearded seals.
🎧 Dr. Tervo provides public access to the live audio stream at the Disko Live home page www.diskolive.com – take a listen. An interactive display is under development for visitors to Qaqqaliaq.
New Product Launch! RTSM Buoy
Launched at Oceanology 2024, our Real-Time Sound Measurement Buoy is a remote monitoring system that can collect, measure, process and transmit noise monitoring data in real-time.
Our RTSM buoy is a lightweight, compact and scalable solution to collecting noise monitoring data. Data is collected in real-time via a hydrophone deployed beneath the remote buoy, making the set-up, management and collection of data seamless in real time.
Applications include:
- Monitoring of offshore pile driving noise
- Real time monitoring of compliance with noise limits
- Live management of acoustic emissions during piling

It also reaffirms our commitment to maintaining the highest industry standards, which sets us apart as a reliable and responsible choice in our sector.
A huge thanks to everyone who contributed to this certification at Seiche.
Underwater Sounds – Live stream
Tune in to live recordings of underwater sounds captured by hydrophones nestled on the seabed at Middelfart, Denmark. This marine protected area is a bustling hub for harbour porpoises, and a collaborative effort between Aarhus University, Naturpark Lillebaelt, and Seiche is bringing real-time monitoring of porpoise activity and ambient sound levels.
Our mission? To unravel the mysteries of why this area is pivotal for porpoises, how their activity ebbs and flows over 24-hour cycles and throughout the year, and the impact of human activities on their behaviour. Using cutting-edge software, we remotely access and manage the system online, with audio and visual feeds streamed directly to the Seiche YouTube channel.
The displays vary depending on how researchers are viewing the data: you may see a spectrogram of ambient sounds, or a map with the tracks of larger vessels (AIS reports), or you may see a click detector display, where porpoise clicks are automatically displayed as red triangles. The audio you will hear blends low-frequency background noises with high-frequency porpoise clicks, that have been dropped down into our hearing range by signal processing techniques (the audible output of an envelope detector).

Drift Buoys Improve Underwater Noise Monitoring
The winter issue of Environment, Coastal and Offshore Magazine (ECO) highlights an article about our data loggers and drift buoys and how they were utilised to measure underwater noise on tidal turbines. This study aimed to identify the possible impact of such noise on marine life near the coast of Shetland.
