Marine Bioacoustics • Environmental Intelligence
Halicho Marine
Understanding underwater acoustics through scientific expertise, quantitative analysis and modern computational methods.
What we do
From underwater sound to ecological evidence.
Halicho Marine provides specialist grey seal bioacoustics, passive acoustic monitoring and evidence-led interpretation for environmental assessment, monitoring and research.
Clients provide hydrophone data. Halicho Marine provides expert review, call classification, quantitative analysis and clear reporting, with uncertainty communicated carefully throughout.
Environmental Consultancy
Support for offshore renewable energy, marine monitoring and environmental assessment through proportionate, evidence-led acoustic analysis.
Quantitative Methods
Statistics, signal processing and machine learning used to improve the efficiency, consistency and transparency of acoustic monitoring workflows.
Grey seal ecology
Field knowledge behind acoustic interpretation.
Halicho Marine's acoustic work is grounded in direct experience with grey seal ecology, coastal monitoring and the practical realities of marine environmental evidence.
Machine learning can accelerate review. Ecological expertise determines what the results mean.
Why Halicho Marine
Specialist expertise in a difficult acoustic problem.
Scientific expertise
Built on original research into underwater seal vocal repertoires, passive acoustic monitoring and environmental acoustic structure.
Consultancy experience
Experience spanning offshore renewable energy, environmental assessment, marine ecology, acoustic monitoring and project delivery.
Evidence-led interpretation
Transforming acoustic recordings into robust ecological evidence while clearly distinguishing results, interpretation and uncertainty.
Scientific restraint
Ecological interpretation, not behaviour detection.
The relationship between underwater seal call types and behaviour remains an active scientific question.
Halicho Marine can investigate relationships between vocal activity, call types, time, tide, ambient noise and other environmental variables. Where ecological interpretation is provided, uncertainty is made explicit and conclusions are clearly separated from hypotheses.
