Municipal Water Leak Explainer Voiceover$0.0063~6s
0:00

A hidden water-main leak can run for months before it reaches the surface. By then, treated water is lost, roads are damaged, and repairs become emergencies. Continuous acoustic monitoring listens for the distinctive signal of escaping water, then helps crews narrow the search before they excavate. The result is earlier detection, fewer unnecessary roadworks, and maintenance planned around the city—not the crisis.

Shellfish Farm Monitoring Explainer$0.0078~6s

By the time harmful organisms are visible, a shellfish crop may already be at risk. TideTrace detects environmental DNA in routine water samples, revealing emerging threats days earlier than visual checks alone. Farm teams receive a clear risk summary, location data, and practical next steps—without installing new equipment offshore. Earlier warning means more time to adjust intake, protect vulnerable stock, and document every decision. TideTrace turns a bottle of seawater into a clearer plan for the week ahead.

Forensic Entomology Training Narration$0.0108~9s
0:00

Insect evidence can help estimate a minimum postmortem interval, but only when the scene is documented before specimens are disturbed. Begin by photographing visible larvae, pupae, and adult insects in place. Record ambient temperature, ground temperature, and the temperature inside the largest larval mass. Next, collect specimens from several locations on and beneath the remains. Preserve one sample immediately, and keep a second sample alive with a small amount of tissue for rearing. Never rely on size alone to identify a larval stage. Species, temperature, and access to the remains all affect development. Your final estimate must combine laboratory identification with weather records and scene conditions.
