USGS Upgrades SEABOSS 3.0 With Fiber Optics, HD Cameras

The US Geological Survey is developing SEABOSS 3.0, an upgraded seafloor observation system that integrates fiber-optic technology and high-definition cameras to extend surveys into deeper water. The new version of the Seabed Observation and Sampling System can operate at depths of up to 500 metres, improving the speed, resolution and reliability of the images, video and sediment samples it collects. Built through collaboration between the Woods Hole and Pacific Coastal and Marine Science Centers, the system recently passed its first round of testing ahead of planned sea trials in late summer 2026.

 

Purpose of the SEABOSS System

 

SEABOSS is a long-established US Geological Survey instrument used to study the seafloor. The system collects seafloor images, video and sediment samples that support research across several fields. This data underpins work on natural hazards and the assessment of offshore resources. The instrument has served as a core tool for marine survey work over an extended period. Its established role provides the foundation on which the latest upgrade builds.

The 3.0 version expands these capabilities in several meaningful ways. The upgrade extends the system's operating depth to as much as 500 metres, opening access to areas previously beyond its reach. Integration of fiber-optic technology and improved camera systems enhances the speed, resolution and reliability of data collection. These changes allow the instrument to capture clearer imagery from deeper environments. The result is a more capable platform for mapping and characterising the seafloor.

 

Origins of the Development Project

 

The development of SEABOSS 3.0 began with knowledge sharing across USGS centres. Work started last year when scientists from the Woods Hole Coastal and Marine Science Center travelled to the Pacific Coastal and Marine Science Center in Santa Cruz, California. There they studied the Benthic Observation camera Sled, known as BOBSled, an existing seafloor imaging system. The visit also allowed them to draw on the expertise of USGS ocean engineer Gerry Hatcher. This exchange of technical knowledge laid the groundwork for the new instrument.

The project illustrates a deliberate model of cross-centre collaboration. Rather than developing the system in isolation, the Woods Hole team built on imaging techniques already proven elsewhere within the agency. Hatcher provided continued advisory support throughout the development process. This approach allowed the team to combine engineering expertise from multiple sources. It reflects a wider emphasis on shared innovation across the USGS Coastal and Marine Hazards and Resources Program.

First Testing Milestone

 

The project reached a significant point with its first round of testing in June 2026. Hatcher travelled to Woods Hole, Massachusetts, to join colleagues in evaluating the new instrument. The team included Seth Ackerman, Eric Moore, Pat Berube, Alex Nichols, Lee Vanderveen and Laura Brothers. Together they assessed the system's performance under controlled conditions. This marked the first time the assembled instrument had been put to the test.

The testing produced encouraging results across several measures. The team successfully operated the system in a test well at the Woods Hole Oceanographic Institution. They evaluated camera performance and assessed how the instrument's frame handled during deployment. These checks confirmed that key elements of the design functioned as intended. The successful outcome represents a major milestone in the system's development.

 

Path to Sea Trials

 

Attention now turns to preparing the instrument for operation at sea. The development team will continue to refine the system in the period ahead. The next major step involves sea trials aboard the R/V Tioga, scheduled for late summer 2026. These trials will test the instrument in real ocean conditions beyond the controlled environment of a test well. Successful trials would move the system closer to operational deployment.

Once complete, the system is expected to support a broad range of research applications. The instrument will help map and characterise the seafloor across various settings. Planned work includes characterising the seafloor surface in the Gulf of Maine alongside the Office of Naval Research. This collaboration points to the system's potential value for partners beyond the USGS. It demonstrates how the upgraded instrument could broaden the reach of seafloor research.

 

Significance for USGS Research

 

SEABOSS 3.0 carries importance beyond its technical specifications. The project demonstrates the value of collaboration across the USGS Coastal and Marine Hazards and Resources Program. By combining engineering skill, field experience and cross-centre innovation, the team has produced a more capable research tool. This collaborative model has been central to the system's progress. It shows how shared expertise can accelerate the development of specialised equipment.

The wider benefit lies in the expanded research the instrument will enable. A system capable of working at greater depths with higher-resolution imaging extends the scope of USGS survey work. Improved data on the seafloor supports better understanding of natural hazards and offshore resources. This strengthens the agency's capacity to map national waters in detail. The upgrade therefore represents an investment in the long-term reach of marine research.
