Dive with Alvin.
Human presence, direct observation, precision sampling.
An Alvin-based research expedition delivers a firsthand experience unlike any other in science: it allows in-situ data collection and observation by two scientists of the seafloor and water column to depths reaching 4,500 meters on dives lasting up to ten hours, with the support of an experienced, multi-talented technical team. The Alvin Group and their equipment meet the highest safety and reliability standards as a result of decades of operational and engineering expertise. Continual innovation and the application of the latest technological advancements puts Alvin at the forefront of expeditionary research.
With seven reversible thrusters, Alvin can hover in the water, maneuver over rugged topography, or rest on the sea floor. With an experienced pilot at the controls, it can collect data throughout the water column, produce a variety of maps and perform photographic surveys. Alvin also has two robotic arms that can manipulate instruments and obtain samples ranging from hard-rock geology to delicate biology, and its basket can be reconfigured daily based on the needs of each dive.
Currently rated to 4,500 meters, Alvin gives researchers in-person access to about two-thirds of the ocean floor, the most recent upgrade increased the depth rating of many of the vehicle’s systems, putting it just steps away from having a depth rating of 6,500 meters, or approximately 98 percent of the seafloor. Alvin is a proven and reliable platform capable of diving for up to 30 days in a row before requiring a scheduled maintenance day. Recent collaborations with autonomous vehicles such as Sentry have proven expansive, allowing research teams to visit promising sites to collect samples and data in-person within hours of their being discovered, and UNOLS-driven technological advances have improved the ability for scientific outreach and collaboration via telepresence.
