Technological Innovation and National Defense

Defending our Coastlines

exploring the oceanEngineering advanced technology is the overarching solution for uncovering the mysteries of deep-sea ecosystems and how they can benefit people, like revealing new sources for medical drugs, food and energy resources. It is important to providing enhanced security for all Floridians and United States citizens. 抖M女仆 Harbor Branch works with major defense contractors and the U.S. Department of Defense on coastal security projects that improve the U.S. Navy鈥檚 ability to detect foreign enemies and other ocean-borne threats.

Exploring the Ocean and the drive to overcome the formidable technical challenges of ocean research was essential to the founding of 抖M女仆 (抖M女仆) Harbor Branch Oceanographic Institute by J. Seward Johnson Sr. in 1971. This spirit was embodied by Johnson鈥檚 friend, inventor Edwin A. Link, whose lifetime of innovation included the first flight simulator, the first diver lock-out submersible and the Johnson-Sea-Link submersibles. Discoveries enabled by Link鈥檚 work, such as 贵濒辞谤颈诲补鈥檚 deep-water coral reefs and the collection and safeguarding of thousands of marine organisms used in 抖M女仆 Harbor Branch drug discovery efforts, continue to shape our understanding and appreciation of the oceans.

Since the beginning of oceanography in the early nineteenth century, the big advances have been the result of new developments in technology, which are like windows into the ocean that nobody鈥檚 ever seen before.鈥

The Issue

More than 70% of the planet is covered by water. However, only a small percentage of the oceans have been studied. Technological advancements are allowing scientists to reach deeper depths of this mysterious realm and in new, noninvasive ways.

In addition to learning more about the natural world, uncovering the mysteries of deep-sea ecosystems can benefit people, like revealing new sources for medical drugs, food and energy resources, and even benefit the Nation鈥檚 coastline security.

Information from ocean exploration can also help predict earthquakes and tsunamis and help us understand how we are affecting and being affected by changes in the Earth鈥檚 environment.



  • More than 70% of the planet is covered by water
  • More than 80% of the ocean is unmapped, unobserved and unexplored
  • 鈥淔lorida current鈥 portion of the Gulf Stream could generate between 4 and 6 gigawatts of power
  • Less than 20% of the global seafloor has been mapped
  • 贵濒辞谤颈诲补鈥檚 military and defense industry provides $95 billion in economic impact



exploring the ocean抖M女仆 Harbor Branch Taking Action

Inspired by Johnson and Link鈥檚 legacy, we develop revolutionary and cutting-edge technologies that enable us to discover, map, observe, quantify, sample and conserve the ocean鈥檚 diverse organisms and habitats.

National Defense Technologies

Engineering advanced technology is critical to providing enhanced security across the Nation. 抖M女仆 Harbor Branch works with major defense contractors and the U.S. Department of Defense to better understand the oceanic environment in which the Navy operates and the biological, chemical, and physical processes that regulate that environment. One research project is investigating the potential to use vocalizations from resident fish populations to warn against coastline invasion. As an added benefit, this important work also yields insights that inform overarching solutions for degraded coastal and ocean environments.



Renewable Energy

One of the world鈥檚 strongest currents, the Gulf Stream, flows at speeds up to 5.6 miles per hour and transports nearly four billion cubic feet of water per second from Florida to Europe. The Southeast National Marine Renewable Energy Center (SNMREC) is a U.S. Department of Energy recognized center at 抖M女仆, focused on the safe and responsible use of marine renewable energy from the Gulf Stream. The ultimate goal is to harness this extreme natural force to power some of 贵濒辞谤颈诲补鈥檚 most populated coastal communities sustainably. At the core of SNMREC research is a novel ocean turbine prototype created and deployed by 抖M女仆 Harbor Branch ocean engineers. The Institute is poised to take this technology from prototype to landing a permanent place within the Nation鈥檚 alternative energy portfolio.



Unmanned Underwater Research

The advent of Autonomous Underwater Vehicle (AUV) technology has dramatically increased the efficiency, frequency and depth of underwater exploration missions. AUVs are specialized robots capable of operating on their own using onboard computers, sensors and batteries. These instruments can conduct missions for months at a time, traveling vast distances and diving to depths of more than 18,000 feet. Scientists at 抖M女仆 Harbor Branch develop and use specialized AUVs outfitted with advanced sensors to collect oceanographic data and study such topics as the physical features of the seafloor, ecology of deep-water coral reefs and endangered fish spawning aggregations.



Ocean Optics

Light is the foundation of life on the Earth and in the oceans. The color and clarity of seawater, as well as the dissolved and particulate materials suspended within it, play an important role in the transmission of sunlight through water. From images of microscopic particles to space satellite photographs of entire coastlines, the interdisciplinary team of ocean optics researchers at 抖M女仆 Harbor Branch develop transformative optical technologies to gain better visibility and understanding of the critical processes within our oceans.



Our Outcomes

  • Increased coastal security utilizing state-of-the art ocean engineering and applied technology
  • Novel AUVs and sensor technology deployed for oceanography studies and exploration
  • Enhanced visibility and understanding of the critical processes within our oceans
  • Marine renewable energy generated by the Gulf Stream current as sustainable resource



Resilience and disaster are the two faces of nature. And resilience continually adapts to new emerging threats. So technology inspired by resilience in nature is our best chance to make our lives safer in a changing world.鈥

How You Can Help

Tools and technologies are critical in allowing scientists to reach farther depths of the ocean and answer previously unanswerable questions. Your support can expand ocean exploration capabilities, help uncover and safeguard their immeasurable resources for the benefit of humankind and secure our coastline from foreign-born threats.

Thank you for considering supporting this critical research area. Harbor Branch values our donors as key partners in helping to achieve our vision: 鈥淥cean Science for a Better World.鈥

Marine science suffers because we can鈥檛 see through the water with precision. We need to take on this difficult task to expand the capabilities of modern, deep-sea exploration.鈥
