Every year, billions of dollars of Florida’s economy depend on understanding what lies beneath the water’s surface. Shipping channels must remain navigable. Beaches require replenishment. Coral reefs protect coastal communities from storm surge. Yet much of the seafloor supporting those activities has never been mapped at modern resolution.
This is not just a problem for Florida. The vast majority of the ocean floor remains largely unexplored. Experts estimate that only about 29% of the global seafloor has been mapped, a gap driven by the sheer scale and difficulty of the work. That gap is not merely a scientific curiosity. Seafloor data informs tsunami warning systems, coastal resilience planning, shipping safety, habitat conservation, and the management of fisheries and underwater infrastructure. Without a complete picture of what lies beneath the surface, the consequences can be devastating, measured in economic losses, compromised national security, and preventable loss of life.
For Florida, there are additional real economic and environmental consequences to not having the full picture of the seafloor, as coastal development, hurricanes and other ecological phenomena are all impacted by local bathymetry.
To address this need, the Florida Department of Environmental Protection set up a mandate to map the seafloor of an entire state’s coastal waters at high resolution. The Florida Seafloor Mapping Initiative (FSMI) is among the most ambitious marine geospatial programs ever undertaken in the United States, covering tens of thousands of square kilometers of continental shelf.
The project’s goal is to produce a seamless digital elevation model (DEM) of Florida’s continental shelf that can serve researchers, regulators, mariners, and the public for decades to come. The DEM will ultimately provide the state of Florida with a map that integrates bathymetric data with a recently collected terrestrial lidar dataset.
Woolpert was tapped to lead major portions of the effort, deploying aircraft equipped with topobathymetric lidar sensors over the Florida Keys and uncrewed surface vessels for sonar-based mapping across the Northeast, Big Bend, and Panhandle regions. With decades of hydrographic surveying experience, advanced processing capabilities, and a track record with emerging technologies at scale, Woolpert was well-positioned to take on a project whose scope would push conventional survey approaches to their limits.
What followed was not just a mapping project. It became a test case for a new model of offshore operations, one that paired autonomous technology with a cloud-native processing platform to keep data flowing continuously from vessel to client.
The Problem
Mapping tens of thousands of linear nautical miles of seafloor is not something traditional hydrographic methods were designed to do quickly. The conventional approach relies on crewed vessels staffed with seasoned mariners and onboard hydrographers, conducting mapping missions offshore for days or weeks at a time and returning to port with hard drives full of raw data that then needs to be processed. The vessels require fuel stops, crew rotations, and port access. They are expensive to mobilize, constrained by human endurance, and routinely sidelined by weather. In past projects of this type, mapping was typically conducted only during summer months when sea conditions were calm enough to operate safely. For a project the scale of FSMI, that seasonal window would have stretched the timeline to three to five years.
The data problem was equally daunting. Survey missions at this scale can generate petabytes of raw multibeam, navigation, and ancillary sensor data. In a traditional workflow, that data would arrive in batches and move through manual processing steps on locally-installed software. A project of this volume would overwhelm any manual pipeline. Processing backlogs would ultimately translate directly into delayed deliverables, higher costs, and gaps in project visibility.
A Machine That Doesn’t Sleep
Solving those challenges meant looking beyond conventional approaches. One solution was the Mission Capable 29 (MC29), built by Chance Maritime Technologies of Lafayette, Louisiana. MC29 is a 29-foot diesel-powered surface vessel that looks, at first glance, like a modest workboat. It is only when you observe it a bit closer that you realize there is nowhere to put anyone operating the vessel, and that’s by design. Uncrewed and piloted remotely, the MC29 is purpose-built for multi-week endurance without refueling and engineered throughout for seaworthiness, reliability, and uptime.
The natural question is whether you can actually trust a 29-foot uncrewed boat operating alone, out of sight, thousands of kilometers offshore, to collect the kind of precise, high-stakes hydrographic data that coastal management, navigation safety, and habitat protection decisions will rest on for decades. Skepticism that this is even possible is understandable. What made it workable, however, was the degree to which that skepticism was anticipated – and designed against – from the beginning.
For the FSMI deployment, the vessel was outfitted with Woolpert’s hydrographic sensor package at the core of which was an R2Sonic 2026 multibeam echosounder, backed by an Applanix OceanMaster inertial navigation system for precise motion compensation, dual Valeport Swift sound velocity profilers deployed from custom deck winches, and Trimble CenterPoint RTX satellite-based positioning delivering horizontal accuracy on the order of three centimeters. Together, the sensor suite allowed the MC29 to acquire high-resolution bathymetric data in water depths reaching 220 meters and at distances up to 100 kilometers from shore.
What the MC29 does not do is sleep. It can operate 24 hours a day, seven days a week. During the survey it was remotely piloted by Chance Maritime personnel and monitored by a globally distributed team of Woolpert hydrographers in Alaska, South Carolina, Ireland, and Australia, each working consecutive six- or eight-hour shifts. The team used time zone differences as a scheduling asset, not a constraint.
Triple-redundant Starlink satellite terminals maintained continuous broadband connectivity, and redundancy runs throughout the MC29’s architecture: dual acquisition computers, dual navigation logging systems, dual sound velocity profilers, and triple-redundant communications terminals. In operation, that fault-tolerant design allowed the system to maintain survey continuity even in the face of component failures.
The Data That Never Stops Moving
The MC29 solved one problem, but immediately created another. A vessel that never stops collecting data is only an advantage if you can keep pace with what it produces. In a traditional survey workflow, data accumulates on a vessel for days or weeks and then needs to be processed once everyone returns to port. At the scale of FSMI, generating terabytes of raw multibeam, navigation and ancillary sensor data, that processing queue would have swallowed the project whole. The vessel may be able to run around the cock, but without a processing pipeline to match its cadence, the data advantage would evaporate.
Getting that data processed, validated, and delivered in near real time, however, is what Woolpert’s Automated Survey Production Environment, ASPEN was created to solve. ASPEN is a cloud-native, modular processing framework built by Woolpert to manage the full hydrographic survey lifecycle, from acquisition through delivery. As soon as the MC29 transmitted raw multibeam, navigation, and ancillary sensor data to Woolpert’s cloud infrastructure, automated routines triggered the next phase of the workflow without requiring manual intervention or physical media transfers. The pipeline is designed to run continuously, matching the cadence of the vessel itself.
Within ASPEN, quality control checks on standard deviation and positioning uncertainty run automatically, multiple datasets are validated in parallel, and bathymetric surfaces build continuously as new data arrives. The practical result was that Florida DEP could watch their seafloor emerge in near real time through ASPEN’s WebGIS portal, in both 2D and immersive 3D environments, with live vessel tracking alongside. Rather than waiting weeks for a processed deliverable, the client had visibility into the survey almost as fast as the water beneath the MC29 could be measured.
What They Found
The team identified and mapped blue holes, coral reef systems, and more than a dozen shipwrecks, among them a 170-meter floating dry dock sunk in 40 meters of water to create an artificial reef. The data revealed features that had never been documented at this resolution, offering researchers, habitat managers, and the public a picture of Florida’s coastal seafloor that simply did not exist before.
When the Storm Hit
In October 2024, Hurricane Milton made landfall across Florida’s peninsular coast as the strongest tropical cyclone anywhere in the world that year. In the hours that followed, with the Tampa Bay region still reeling, a critical question needed an urgent answer: was the shipping channel into Tampa Bay clear enough for tanker traffic to resume?
The Woolpert team mobilized quickly. Using the survey capabilities and workflows already proven through FSMI, they mapped the dredged channel and confirmed there were no debris blockages obstructing passage. Large tankers were able to enter the bay within hours of the survey, in the crucial window when fuel, supplies, and recovery resources were most desperately needed.
It was a moment that illustrated something the project’s technical achievements can sometimes obscure: the reason this work matters. Knowing what is under the water is not just a scientific exercise. In the aftermath of a catastrophic storm, it is the difference between a port that opens and one that doesn’t.
Results
The results of Woolpert’s involvement in FSMI were significant in both scale and precision. Every dataset collected, including data acquired autonomously by the MC29, met or exceeded IHO Order 1a specifications, the industry benchmark for high-quality hydrographic surveys. The MC29 alone accounted for more than 3,000 square kilometers of that coverage, demonstrating that uncrewed systems are capable of primary survey execution rather than simply supporting crewed operations.
Operational resilience was one of the project’s defining achievements. During winter missions, the MC29 continued collecting data through six- to eight-foot seas while the R/V Thunder, Woolpert’s 70-foot crewed vessel operating in the same region, remained at dock. The uncrewed vessel sustained continuous 24/7 operations for over 20 days without returning to port for refueling or crew changes. Also proven effective was the follow-the-sun model, with the globally distributed staff maintaining uninterrupted oversight of data acquisition around the clock.
Behind the scenes, the ASPEN platform transformed what happened to that data once it left the vessel. Automated cleaning, gridding, and validation replaced the manual file handling that typically creates bottlenecks in large-scale survey workflows, compressing turnaround times significantly. For the first time, Florida DEP could interact with survey results in near real time through ASPEN’s WebGIS portal, which offered both 2D map views and immersive 3D bathymetric environments alongside live vessel tracking.
A Broader Impact
Looking further ahead, the mapping identified underwater sand deposits essential for beach restoration and documented reef structures that serve as natural storm buffers for coastal communities. Those contributions are tied to an estimated $28 million annual return on investment for the state of Florida, a figure that will only grow as the dataset becomes publicly available through the planned portal launch in 2027.
Conclusion
For Woolpert, FSMI was proof of concept at the highest possible stakes. An uncrewed vessel, a global team, and a cloud-native processing platform mapped tens of thousands of square kilometers of seafloor that had never been seen at this resolution, through hurricanes, six-foot seas, and petabytes of data. The MC29 operated through conditions that grounded traditional vessels. ASPEN gave clients visibility into their survey as it happened. Together, they changed what offshore hydrographic survey can look like.
The workflows proven here won’t stop at Florida’s coastline. There is a lot of seafloor left to map.
