Baseline program requires multi-million-dollar annual monitoring (approx. $3.2M/yr) driven by vessel/ROV missions, staff, and remote sensors; a one-time program capital budget is dominated by an optional active-containment build (~$200M) if chosen.

Environmental Reporting And Compliance $10K/yr
[19] Recurring reporting and compliance monitoring costs for national authorities.
Active Containment Ops $0/yr
[25] Recurring operations for active containment (set to 0 in baseline because active containment is not pursued in baseline program).
⚡ Cost Scenarios
📊 Baseline (baseline) $3.2M/yr
84.5% probability / year
Normal monitoring and discouragement year with no major incidents: hydrophone network, modest ROV/AUV operations, core staff and routine analyses.
scheduled monitoring missions routine analysis and maintenance
🚨 Minor Incident $5.7M/yr
15.0% probability / year +$2.5M vs baseline
Expedition damage / equipment loss or emergency response year requiring rapid-response vessel charter, repairs, and legal/insurance expenditures.
equipment failure during deep expedition emergency salvage/repair incident-driven legal or environmental response
🚨 Active Containment Scaleup $223.2M/yr
0.5% probability / year +$220.0M vs baseline
Policy decision to pursue active capture/containment leading to major capital outlays and scaling of operations in the year of ramp-up.
mandate to capture/contain live specimens large-scale engineering and seafloor construction

Role Count Notes
Research Scientist 2 [8] Oceanographers/marine geologists leading analyses and field science.
ROV Pilot / Technician 1 [8,1,9] ROV/DSV operators for missions and vehicle maintenance.
Engineer / Systems Engineer 1 [8,4,5] Systems engineer for vehicles, moorings, and prototype pressure systems.
Site / Program Manager 1 [8,24] Program lead coordinating operations, permits, and liaison.
Data Analyst / Technician 1 [18,7] Video/sonar processing, data management, and contract coordination.
📋 Confidence Notes
Cost ranges in analyst notes are broad for deep-hadal operations and many costs depend on mission tempo and policy choices; line-item mappings are traceable but uncertainty in vessel day-rates, R&D outcomes, and the optional active-containment path reduce confidence.
