[DIRECTIVE: THE_PATH_TO_2027]
This roadmap defines the ‘Lean Science’ architecture and operational milestones for the HMS Stewards 2026/2027 pilot season.
[GOVERNANCE: ADVISORY_BRAIN_TRUST]
- Founding Pillars: Industry veterans anchoring Systems Public Policy and Technical Architecture.
- Professional Reciprocity: We prioritize Wisdom over Labor, engaging technical partners through transparent, arms-length contracting for specialized builds.
[FISCAL_MODEL: SOCIAL_ENTERPRISE]
- 12% Royalty: Our commercial arm fuels the mission by returning a royalty on all hardware sales back to the research fund.
- Public Good: The Nonprofit retains 100% ownership of IP to ensure open-access water intelligence.
[TARGET_ZONE: SEACOAST_WATERSHED]
Our pilot implementation covers the high-stakes confluence of the Great Bay and Piscataqua River.
- Tributary Audit: High-resolution monitoring of the Five Rivers (Bellamy, Oyster, Lamprey, Squamscott, and Winnicut).
- Cross-Border Operations: Expanding coverage to Kittery, ME, and the Salmon Falls/Cochecho confluence to facilitate interstate regional grant qualification.
- Strategic Alignment: Data flow and telemetry optimized for seamless integration with PREP and Great Bay Stewards reporting.
[INTEL_SCALING: CITIZEN_SCIENCE_LMS]
- TIER_01: Watershed Literacy & Forensic Basics.
- TIER_02: Field Instrumentation & Sensor Calibration.
- TIER_03: Data Advocacy & Municipal Reporting Protocols.
[SYSTEMS_DIRECTIVE: OPERATIONAL_EDGE]
By utilizing a modular architecture, we provide 4K visual evidence and chemical ‘ground truth’ at a fraction of the capital risk. This allows HMS Stewards to navigate high-debris forensic hotspots—areas physically and financially inaccessible to high-liability industrial equipment.
[SYSTEM_ARCHITECTURE: HMS_GHOST_V1]
- CORE LOGIC: Integrated Feather M4 Express architecture utilizing CircuitPython for high-speed sensor polling and UTC-synchronized data logging with ISO1540 I2C Isolation to protect signal integrity from electromagnetic motor interference.
- Forensic Sensing Stack: Integrated EZO™ research-grade sensors for pH, Conductivity (Salinity), and Dissolved Oxygen, enabling laboratory-level accuracy, providing research-grade chemical telemetry.
- Physical Proxies: Real-time Turbidity and Spectral Attenuation monitoring to identify sediment spikes and nutrient proxies (Nitrate/Phosphate).
- Sub-Surface Depth Auditing: Bar30 High-Pressure sensing paired with a 35KG High-Torque Winch with a 3m Shielded SMA Umbilical for deep-column “Salt Wedge” detection.
- Visual Ground-Truth: 4K D-Log Forensic Video with all-weather external power, providing a synchronized “Single Source of Truth” for every chemical data point.
- Propulsion & Recovery: 1400KV Brushless Marine Drive managed by a Daly Smart BMS, ensuring high-current stability during heavy-current tidal ebbs.
- Telemetry: Integrated FlySky 6Ch Radio Link with real-time field telemetry for manual and semi-autonomous navigation.

[STRATEGIC_DIRECTIVE: LEAN_SCIENCE_SCALING]
The HMS Advantage: To de-risk our strategy, we are building agency-grade Mobile Sensing Units (MSU) for under $2,500—proving our model can scale into high-risk areas where $15,000 industrial sondes cannot be risked.
[DEPLOYMENT_MODES: DUAL_PLATFORM_VERSATILITY]
- Vessel-Mounted: For “Source-to-Sea” transects via the R/V HMS Buttercup, focusing on high-volume, deep-channel estuary profiles where engine power and stability are required for heavy-current deployment.
- Sustainable Resilience: The Whaly 380 R/V is engineered from 100% recyclable, high-impact HDPE, providing a near-indestructible platform for forensic auditing. Paired with the Tohatsu MFS30D, which delivers best-in-class fuel economy and ultra-low emissions, minimizes the mission’s environmental footprint.
- RC-Skiff (“The HMS ‘Ghost’ MSU”): A 6″ PVC shallow-draft catamaran engineered for forensic mapping in inaccessible urban zones (e.g., North Mill Pond). This unit is the primary asset for documenting illegal runoff and snow-dumping with surgical precision in waters where standard vessels cannot navigate.
- Tactical Versatility: The ‘Ghost’ MSU micro-catamaran offers a dual-mode deployment strategy—seamlessly transitioning between a stable hip-tow for high-speed transit and independent remote operations for precision sampling in sensitive “Forensic Hotspots.”

AI Concept: [UNIT: HMS_GHOST // CONFIG: DUAL-PONTOON_ASV // STATUS: PROTOTYPE_01]
[DATA_LOGIC: ADVANCED_ANALYTE_MODELING]
Instead of expensive, high-drift hardware, HMS utilizes a Scout-and-Sample protocol to hunt for pollution signatures:
- Chloride (Road Salt): Derived via Specific Conductance mapped against NHDES-validated curves.
- Nutrients (Nitrates/Phosphates): HMS uses Turbidity and Dissolved Oxygen (DO) as “Scout” parameters.
- Trigger Protocol: Detected anomalies initiate an automated Targeted Grab-Sampling protocol for certified lab analysis.
[MILESTONE: SYNCHRONIZED_DATA_PACKAGE_ARCHIVING]
- Activity Focus: Every mission generates a “Data Package” where 4K optical evidence is hard-linked to chemical telemetry via UTC timestamps.
- Result: Researchers can instantly correlate a localized nitrate spike to the exact visual frame—providing a “Single Source of Truth” for municipal reporting and state-level advocacy.
