01
Carbon programs
Measure relevant water and seabed conditions around carbon removal, storage, or habitat projects over the verification period.
Application / Environmental monitoring and MRV
Persistent environmental sensing from the seafloor.
Aphotic leaves mission-specific sensors, compute, storage, and underwater communication in place for long-duration ocean monitoring, event detection, and measurement programs.
Primary objectiveCollect repeatable measurements over long periods
System configurationDistributed Argus nodes selected by depth
Operator outputTime series, events, provenance, and retained evidence
Monitoring designed around the duration of the environmental process.
Many environmental programs depend on measurements collected during short campaigns even though the process being studied changes over seasons or years. Argus nodes remain on the seafloor for 12 to 24 months, creating a continuous record of baseline conditions, transient events, seasonal change, and long-term response from the same locations.
Each node can carry the chemical, optical, acoustic, and physical sensors required by the program. On-edge models manage energy and sampling, identify meaningful changes, compress results for limited underwater links, and preserve detailed data locally. Nexus manages mission configuration, live system health, data provenance, spatial comparison, and the relationship between measurements collected across the field.
02
Water quality
Collect continuous or event-driven measurements of oxygen, temperature, salinity, turbidity, and chemistry.
03
Habitat response
Pair acoustic and optical observations with physical measurements to understand how biological communities change.
04
Audit and reporting
Maintain time-stamped data, mission configuration, calibration records, and system health information for review.
System approach
A persistent field provides both spatial coverage and temporal continuity.
The same network can establish a baseline, observe project activity, and continue measuring response after vessels and installation teams leave.
Relevant systems
Select the Argus housing by depth and the sensor stack by mission.
Argus A, B, and X share a common seabed sensing, edge-processing, storage, power-management, and acoustic-communications architecture. Atlas services the deployed fleet, while Nexus provides the operating picture, planning, alerts, and tasking above it.
