Sea & Shoreline
Restoring Aquatic Ecosystems for People, Nature, and Economies

Beneath the water’s surface lies a world that feeds us, shields our coasts, and breathes life into the planet. But today, aquatic ecosystems are disappearing at an alarming pace, with more than two football fields of seagrass lost every day. Algae blooms, declining vegetation, and rising coastal pressures are reshaping waterways and shorelines. With most of humanity living near coasts or freshwater bodies, the stakes are high.

Florida-based Sea & Shoreline has earned its reputation by tackling these challenges with proven science, scalable restoration practices, and a steadfast commitment to both the environment and the communities that rely on it. Backed by more than two decades of experience and hundreds of successful projects, the company is among the most established players in aquatic restoration.

“Ecosystem restoration breathes life into both nature and communities, strengthening wildlife, tourism, fisheries, property values, and overall quality of life,” says Carter Henne, CEO and chairman.

The company enacts this vision by restoring degraded systems into thriving habitats that support fish, wildlife, recreation, and local economies. It restores submerged aquatic vegetation and seagrass meadows, manages dredging and propeller scar repair, and constructs oyster reefs, wetlands, living shorelines, and breakwaters. Sea & Shoreline’s approach goes beyond quick interventions, focusing on watershed health, nutrient management, and long-term resilience. Its turnkey solutions are designed to endure future pressures. Driving this effort is one of the world’s largest company-owned aquaculture nurseries, dedicated to seagrasses and backed by patented processes.

Coral restoration is another expanding area, with surveying, mapping, and mitigation banking. All are guided by a simple principle: restoration must be cultivated and maintained like agriculture. No farmer expects to plant seeds and return months later to a healthy crop. Similarly, aquatic systems must be carefully tended until they are able to flourish on their own. This integration of biology, farming techniques, and proprietary technology underpins the breadth and depth of its services.

The Kings Bay Restoration Project in Crystal River demonstrates the impact of these services. Years of nutrient loading and invasive algae created Lyngbya, drove away sea life searching for sustenance and shelter and limited ecotourism. Sea & Shoreline was hired by the non-profit Save Crystal River to dredge muck, replant grasses, and protect them until the ecosystem was fully reestablished. Today, over 100 acres have been restored and 850+ previously unidentified spring vents have been opened, resulting in better water clarity, the return of manatees and other sea life, and a thriving ecosystem. Property values along the waterfront have risen in parallel, illustrating how ecological health translates directly into economic and social gains.

These successful outcomes were made possible by the perseverance, community engagement and government support championed by Save Crystal River and the scientific expertise of Sea & Shoreline. Biologists, engineers, and geologists work alongside divers to restore the ecosystems, foster environmental stewardship, create meaningful careers, and strengthen local economies.

Looking ahead, Sea & Shoreline is expanding nursery operations in response to the global coral crisis to support small island nations and other vulnerable communities. The company is designing offshore wave breaks and hybrid reef systems that both protect coastal infrastructure and create conditions for biodiversity to rebound. Simultaneously, it is strengthening the resilience of corals and aquatic plants to withstand environmental stresses, while implementing watershed-level nutrient management to intercept pollutants before they reach vulnerable waterways. Together, these efforts reflect a shift from reactive fixes to proactive, globally scalable solutions.

Sea & Shoreline’s trajectory underscores a simple truth that healthy aquatic systems and thriving communities are inseparable. By combining science, engaging local leaders and government, and committing to measurable outcomes, the company has become a trusted partner in environmental renewal and set a blueprint for a more sustainable future.
