DATA ANALYSIS SERVICES

Full-Stack Passive Acoustic Pipeline

Our start-to-finish workflow processes raw underwater audio into validated detections and interactive data products via PAMPortal.

Analytical Workflow

Processing & Data Visualization Process

Step 1

File Prep & Data Structuring

Data is organized, configuration files are parameterized, and naming conventions are standardized. Environmental or anthropogenic data may be integrated, and baseline soundscape metrics and are calculated with optional addition of other acoustic indices.

Step 2

PAMGuard Semi-Automated Workflow

Data is processed using PAMGuard
with tested configurations tailored to priority marine mammal species, producing detailed detection outputs for downstream analysis. Final analysis is post-processed using PAMPal for acoustic event extraction.

Step 3

Deep Learning Integration

Custom neural networks from DeepAcoustics are applied for specific calls, multi-class detection, or clustering vocal repertoires - improving results in complex or noisy datasets.

Step 4

Delivery via PAMPortal

Final data products are delivered through PAMPortal, a cloud-based tool offering transparent, filterable access to processed acoustic detections and metrics.

LARGE DATASET PROCESSING

Global Capability,

Transparent Results

Our passive acoustic analysis workflow is designed to support projects regardless of recording platform or geographic region. We have processed marine mammal acoustic data from Arctic ice edges, the temperate Pacific, Norwegian waters, and beyond. No matter the deployment conditions or species of interest, our approach ensures that end users receive high-quality, interpretable data products with full visibility and access through our transparent delivery tools.
