October 28, 2022 — The following was released by the Woods Hole Oceanographic Institution:
Woods Hole Oceanographic Institution (WHOI) has been recognized by IEEE, the world’s largest technical professional organization advancing technology, through its Milestone program for the long-running success of its human-occupied submersible Alvin.
The Milestone program honors significant technical achievements in all areas associated with IEEE. Milestones recognize the technological innovation and excellence for the benefit of humanity found in unique products, services, papers, and patents. Each Milestone recognizes a significant technical achievement that occurred at least 25 years ago in an area of technology represented in IEEE and having at least regional impact. To date, more than 240 Milestones have been approved and dedicated around the world.
“Alvin’s significance to ocean science was, and continues to be, far reaching and profound,” said Anna Michel, Chief Scientist of Deep Submergence for the National Deep Submergence Facility at WHOI, the National Science Foundation-funded group that oversees Alvin’s operation. “It opened new avenues of research and discoveries in oceanography and evolutionary biology, and this IEEE Milestone commemorates the decades of Alvin’s engineering breakthroughs that made these scientific discoveries possible and that allow the sub to remain at the leading edge of deep-ocean research.”
Milestones can be nominated by any IEEE member, and after recommendation by the IEEE History Committee and approval by the IEEE Board of Directors, a bronze plaque commemorating the achievement is placed at an appropriate site with an accompanying dedication ceremony.
Alvin is named after Allyn Vine, the WHOI physicist and instrument developer who provided the creative vision to build the sub beginning in the 1950s. The U.S. Navy commissioned Alvin in 1965 and continues to support the submersible program. In the years that followed, engineers used Alvin as the motivation to develop acoustical navigation (ALNAV), communications, photographic, lighting, and life support systems specifically intended for use in the deep ocean. Over the years, Alvin has become one of the most widely used research submersibles in the world, amassing more than 5,100 dives over 57 years and undergoing periodic improvements that have repeatedly extended and improved its capabilities.
Alvin is well known for supporting exploration of the wreckage of HMS Titanic, leading the discovery of the effects of seafloor environmental conditions on microbial communities, and providing access to hydrothermal vents that revolutionized scientists’ understanding of life on Earth. It even helped recover a lost hydrogen bomb in the Mediterranean Sea less than a year after it was commissioned.
Alvin continues to evolve–and to make history. In August 2022, after a two-year overhaul and upgrade, Alvin returned to scientific research with a new maximum depth of 6500 meters (4 miles). The added range puts roughly 99% of the seafloor within reach of the world’s longest-operating, most active, and, by many measures, most successful human-occupied submersible program in the world.
“The Alvin Team are proud and honored to uphold the tradition of Deep Submergence at WHOI with this vastly improved submersible,” said NDSF Director Andy Bowen. “Going to such extreme depths and exploring the ocean inside Alvin is anything but routine—and the fact that we do so with such regularity and success is a testament to the engineering excellence that Alvin embodies.”
The Milestone plaque will be mounted at WHOI’s Smith Laboratory, which currently houses the team that oversees the sub’s operation.
