Services
Halicho Marine helps consultants, developers and researchers understand grey seal acoustic activity from hydrophone datasets.
Processing and interpretation of long-duration hydrophone recordings for grey seal acoustic presence and temporal activity patterns.
Expert review of underwater seal calls using spectrograms, audio and specialist knowledge of repertoire structure.
Independent review of automated detections, detector outputs or manually labelled datasets to improve confidence and reporting quality.
Analysis of call families, subtype structure and temporal variation within underwater seal vocal datasets.
Explore relationships between vocal activity and environmental variables such as time, tide, season and ambient noise.
Development, evaluation and application of computational workflows to make acoustic monitoring more efficient and repeatable.
Monitoring context
Identifying whether grey seals are acoustically active within a monitoring dataset.
Reviewing how vocal activity changes across time, tide, noise conditions and recording context.
Translating detections and call classifications into proportionate, clearly caveated evidence.
The deliverable is not simply a list of detections. It is interpreted evidence that can support environmental assessment, monitoring design and consenting decisions.
