Our Services

We’ve developed a range of services to connect clients with the information they need. Our equipment, skills, and experience provide clients with support, expertise and advice in underwater acoustics, wherever they are in the world.

Marine Mammal Monitoring


Underwater acoustics can be used to identify the presence and explore the behaviour of wildlife underwater. Gather and analyse detailed, robust data. The duration and complexity of Marine Mammal Monitoring can be tailored to any objectives and budget.

Passive Acoustic Monitoring (PAM)


Gather accurate, detailed data from any underwater location in the world. Monitoring solutions are customised to client needs by our science team.

Underwater Noise


Build reliable, scientific underwater noise models from any source signal. Incorporate real-world data to inform mitigation recommendations for reducing acoustic disturbances on marine life.

Automated Signal Detection


Automatically detect and classify acoustic signals to monitor or track marine mammals, fish or vessels.

Data Analysis


Use our data analysis service for processing high volumes of any acoustic data easier so you can focus on your science.

Case Study

Channel deepening and cruise berth project in Lyttelton Harbour.
Client: Lyttelton Port Company

Researching Hector’s Dolphins in Lyttelton Harbour

Researching Hector’s Dolphins in Lyttelton Harbour

Lyttelton Harbour in New Zealand is a special marine environment within the Banks Peninsula Marine Mammal Sanctuary and provides habitat for the endangered Hector’s Dolphin.

To keep up with growing demand, The Lyttelton Port Company (LPC) needed to deepen the approach channel for large vessels and construct a new cruise berth terminal. They needed Underwater Acoustic expertise to help them proceed without negatively impacting the marine environment.
