Turning underwater sound into ecological evidence.
What we do
Specialist grey seal bioacoustics for environmental decision-making.
Halicho Marine supports offshore renewables, monitoring programmes and research by interpreting underwater acoustic recordings.
Acoustic datasets are reviewed, classified, analysed and reported with scientific care, so results can be used with confidence in project decisions.
PAM analysis
Support for passive acoustic monitoring datasets and reporting.
Expert verification
Review of acoustic labels, classifications and supporting evidence.
Environmental context
Analysis of temporal, tidal and acoustic conditions around vocal activity.
Evidence-led interpretation
The output is more than a list of detections.
The deliverable is interpreted evidence that can support environmental assessment, monitoring design and consenting decisions.
Spectrogram review
Visualising acoustic structure supports careful verification and classification.
Call morphology
Short acoustic examples help communicate the patterns behind repertoire analysis.
