Land and passive acoustic monitoring of Kep dolphins

Findings

• The study compares shore-based observations and passive acoustic detection in Kep during August 2018–June 2019, using matched periods across 22 days.
• Detection differed between methods; combining approaches can improve monitoring. The recorder position is not a dolphin encounter location. Abstract pp.51–52; analysis p.55.

How the evidence was collected

Acoustic and shore-based monitoring ran during August 2018–June 2019. The paper compares matched observation periods across 22 days. The map locates the recorder; it does not plot individual dolphin encounters or a population trend.

What the evidence can tell us

Acoustic detections show dolphin activity during recorder deployments, not the number of individual dolphins.
