Marine Research Applications

AUVs have revolutionized marine and ocean exploration. What was once an expensive, limited endeavor completely reliant on surface vessels is now accomplished by AUVs, or self-powered undersea robots that gather high-resolution remote spatial and temporal measurements.

AUVs offer a nimble, flexible alternative to traditional surface vessels. They can glide close to the surface, dive to depths of up to 6000 meters, explore shallow waters or hover in hazardous areas where navigation is difficult. The benefits are numerous. AUVs have reduced the high costs of ocean exploration and sampling while increasing the availability, quality and quantity of scientific marine data.

Primary Applications

Marine Biology

Physical Oceanography

Environmental Monitoring

Marine/Geology Investigation



The units are modular, allowing scientists to change the onboard instruments or payloads to better suit their needs; they can be operated from a vessel of opportunity, dedicated research ship and even the shoreline; and they can be used to explore open water or formerly inaccessible locations such as abyssal plains or under polar ice. Whether conducting an oceanographic investigation of a water column or a geophysical study of the sea bed, Hydroid AUVs allow researchers to achieve multiple objectives in a single dive.

Sensors can be placed close to the area of interest. Coupled with high quality navigation solutions this ensures the data is both meaningful and accurate.

They are quick and easy to deploy around the world, and most units require minimal installation and calibration, thereby reducing ship time and research assets.

The endurance of an AUV allows the vehicle to investigate a larger area for a longer period of time. In addition, the potential to network multiple AUVs together can increase productivity to levels never seen before in marine research.

R&D Efforts

Hydroid's R&D efforts have focused on enabling AUVs to operate multiple payload sensors simultaneously, as this is the real advantage AUVs offer over traditional survey methods. In addition, researchers have spent more than 15 years on lowering the platform’s signature (electrically, acoustically and magnetically), as well as carefully selecting payload sensor frequencies and managing their synchronization. The result - whether marine or fresh, pelagic or benthic, photic or aphotic - Hydroid AUVs are uniquely equipped to gather high-quality data in a wide range of ocean environments.

AUV Models

Hydroid AUVs offer flexible configuration options for adding new sensors and back seat driver solutions as well as an open interface. The REMUS AUV is available in three models: REMUS 100, REMUS 600 and REMUS 6000. The lightweight and compact REMUS 100 is designed for shallow water work up to 100 meters; the mid-range REMUS 600 can operate in depths of 600 or 1500 meters; and the deep-water REMUS 6000 workhorse operates in water up to 6000 meters deep.
