Bridging the Data Gap
Most people don’t realize our watershed is essentially “blind.”
New Hampshire’s Seacoast is changing faster than our data can keep up. Traditional monitoring is expensive, slow, and leaves massive forensic “blind spots.”
HMS Stewards provides high-resolution, agency-grade water intelligence by combining the power of a trained community with proprietary robotic sensing.
[ST-01] CONNECT (the Stewards)
Certified citizens use professional-grade kits to monitor their local “source” waters. They are our eyes and ears on the ground.
[ST-02] UNDERSTAND (the Ghost)
When Stewards detect an anomaly, we deploy the HMS ‘Ghost’ MSU. This semi-autonomous Mobile Sensing Unit provides the 4K visual evidence and chemical telemetry needed for forensic validation.
ST-03: PROTECT (the Data)
We archive every mission into a “Relational Forensic Data-Vault”—a single source of truth for researchers and municipal leaders to drive real mitigation.

Turning Trends into Evidence
We map road-salt plumes and nutrient runoff with UTC-synchronized telemetry. We don’t just report data; we deliver actionable community evidence to the 52 towns that depend on the Great Bay.
The HMS Core Values
[DATA_GAP_ANALYSIS]
For decades, the Great Bay has been studied in isolation. HMS Stewards maps the “Blind Spots”—the non-tidal headwaters and critical arteries that drive the entire system’s health.
The map illustrates how the entire Great Bay ecosystem is shaped by its primary tributaries.
[SENTINEL_SURVEY_GRID]
We are tracking the 10 major tributaries feeding the Piscataqua. From the Lamprey to the Salmon Falls, we gather precise telemetry where the source meets the sea.
[SYSTEMIC_INTEGRITY]
We visualize a connected system. A chemical event in the upper Cocheco is a future event for the Great Bay eelgrass beds. We link 52 communities to their upstream realities.

Data is useless if it’s abstract.
To lead, the community needs Actionable Insight.
We turn a “Literacy Gap” into powerful action by providing the specialized hardware—like the R/V HMS Buttercup and the ‘Ghost’ MSU—required to map our waters with forensic precision.
We generate the Ground Truth—translating raw sensor readings into intuitive, community-accessible stories that empower municipal leaders to act.
