eDNA sampling at sea

eDNA sampling at sea uses water samples to detect species from genetic traces. A wind-propelled Sailbuoy can persistently visit stations, collect samples, and stream mission status via Iridium, reducing crewed days offshore. Month-scale endurance and ~3 kn average speed enable repeatable coverage for baselines and biodiversity studies.

What is eDNA sampling at sea?

Environmental DNA (eDNA) is genetic material shed by organisms into the water. With autonomous routing and solar-powered electronics, a wind-propelled USV can execute repeat sampling plans, log metadata, and report progress and alerts via Iridium. Samples are recovered for lab analysis and QA.

Why does eDNA sampling at sea matter offshore?

Consistent, low-impact sampling improves time-series quality and spatial coverage while limiting HSE exposure. Endurance up to 12 months and geofenced routes reduce mobilizations and vessel-days, helping teams maintain baselines around wind farms, MPAs, and sensitive habitats.

Can the USV adapt routes during a campaign?

Yes. Operators can update waypoints and sampling cadence over Iridium, within predefined safety limits and geofences.

How are samples handled?

The USV preserves samples onboard for recovery and laboratory analysis; mission logs capture timestamps, positions, and conditions.
