Alvin (DSV-2) is a crewed deep-ocean research submersible owned by the United States Navy and operated by the Woods Hole Oceanographic Institution (WHOI) in Woods Hole, Massachusetts. The original vehicle was built by General Mills' Electronics Group in Minneapolis, Minnesota. Named to honor the prime mover and creative inspiration for the vehicle, Allyn Vine, Alvin was commissioned on June 5, 1964.
Hydrothermal vents are fissures on the seabed from which geothermally heated water discharges. They are commonly found near volcanically active places, areas where tectonic plates are moving apart at mid-ocean ridges, ocean basins, and hotspots. The dispersal of hydrothermal fluids throughout the global ocean at active vent sites creates hydrothermal plumes. Hydrothermal deposits are rocks and mineral ore deposits formed by the action of hydrothermal vents.
Riftia pachyptila, commonly known as the giant tube worm and less commonly known as the giant beardworm, is a marine invertebrate in the phylum Annelida related to tube worms commonly found in the intertidal and pelagic zones. R. pachyptila lives on the floor of the Pacific Ocean near hydrothermal vents. The vents provide a natural ambient temperature in their environment ranging from 2 to 30 °C, and this organism can tolerate extremely high hydrogen sulfide levels. These worms can reach a length of 3 m, and their tubular bodies have a diameter of 4 cm (1.6 in).
Kamaʻehuakanaloa Seamount is an active submarine volcano about 22 mi (35 km) off the southeast coast of the island of Hawaii. The top of the seamount is about 3,200 ft (975 m) below sea level. This seamount is on the flank of Mauna Loa, the largest active subaerial shield volcano on Earth. Kamaʻehuakanaloa is the newest volcano in the Hawaiian–Emperor seamount chain, a string of volcanoes that stretches about 3,900 mi (6,200 km) northwest of Kamaʻehuakanaloa. Unlike most active volcanoes in the Pacific Ocean that make up the active plate margins on the Pacific Ring of Fire, Kamaʻehuakanaloa and the other volcanoes of the Hawaiian–Emperor seamount chain are hotspot volcanoes and formed well away from the nearest plate boundary. Volcanoes in the Hawaiian Islands arise from the Hawaii hotspot, and as the youngest volcano in the chain, Kamaʻehuakanaloa is the only Hawaiian volcano in the deep submarine preshield stage of development.
Aliens of the Deep is a 2005 American documentary film directed in part by James Cameron alongside fellow cameraman and friend Steven Quale, and filmed in the IMAX 3D format. It was produced by Walden Media and Walt Disney Pictures. Cameron teams with NASA scientists to explore the mid-ocean ridges, submerged chains of mountains in the Atlantic and Pacific oceans that are home to some of the planet's more unusual forms of life.
A mud volcano or mud dome is a landform created by the eruption of mud or slurries, water and gases. Several geological processes may cause the formation of mud volcanoes. Mud volcanoes are not true igneous volcanoes as they do not produce lava and are not necessarily driven by magmatic activity. Mud volcanoes may range in size from merely 1 or 2 meters high and 1 or 2 meters wide, to 700 meters high and 10 kilometers wide. Smaller mud exudations are sometimes referred to as mud-pots.
The Lost City Hydrothermal Field, often referred to simply as Lost City, is an area of marine alkaline hydrothermal vents located on the Atlantis Massif at the intersection between the Mid-Atlantic Ridge and the Atlantis Transform Fault, in the Atlantic Ocean. It is a long-lived site of active and inactive ultramafic-hosted serpentinization, abiotically producing many simple molecules such as methane and hydrogen which are fundamental to microbial life. As such it has generated scientific interest as a prime location for investigating the origin of life on Earth and other planets similar to it.
Stephen Low is a Canadian film director and screenwriter who works extensively in the IMAX and IMAX 3D film formats. Based in Montreal, Quebec, over his 30-plus year career Low has directed numerous award-winning film documentaries including Challenger: An Industrial Romance (1980), Beavers (1988), Titanica (1991), Super Speedway (1997), Volcanoes of the Deep Sea (2003), Fighter Pilot: Operation Red Flag (2004), Ultimate Wave Tahiti 3D (2010), Legends of Flight 3D (2010), Rescue 3D (2011), Rocky Mountain Express (2011) and Aircraft Carrier (2017).
Adolf "Dolf" Seilacher was a German palaeontologist who worked in evolutionary and ecological palaeobiology for over 60 years. He is best known for his contributions to the study of trace fossils; constructional morphology and structuralism; biostratinomy, Lagerstätten and the Ediacaran biota.
Paleodictyon is a trace fossil, usually interpreted to be a burrow, which appears in the geologic marine record beginning in the Precambrian/Early Cambrian and in modern ocean environments. Paleodictyon were first described by Giuseppe Meneghini in 1850. The origin of the trace fossil is enigmatic and numerous candidates have been proposed.
The Endeavour Hydrothermal Vents are a group of hydrothermal vents in the north-eastern Pacific Ocean, located 260 kilometres (160 mi) southwest of Vancouver Island, British Columbia, Canada. The vent field lies 2,250 metres (7,380 ft) below sea level on the northern Endeavour segment of the Juan de Fuca Ridge. In 1982, dredged sulfide samples were recovered from the area covered in small tube worms and prompted a return to the vent field in August 1984, where the active vent field was confirmed by HOV Alvin on leg 10 of cruise AII-112.
9 North, or Nine North, is a region of hydrothermal vents on the East Pacific Rise in the Pacific Ocean, 900 kilometers off the coast of Acapulco, Mexico; it has been so named by scientists because its latitude is 9°50' N. It was first seen to erupt in 1991 by the deep submersible Alvin during a survey for the Ocean Drilling Program. In November 1999, scientists, students, education specialists, and film crews returned to 9 North to see how the biology and landscape had changed over time. IMAX, National Geographic, and BBC film crews have made videos about the vents at 9 North, most noticeably Volcanoes of the Deep Sea (2003).
Richard Arthur Lutz is an American marine biologist and deep-sea oceanographer. He is known for deep-sea research using the Alvin submersible, and is considered one of the world's foremost authorities on the ecology of deep-sea hydrothermal vents.
Paleodictyon nodosum is a living creature thought to produce a certain form of burrow nearly identical to Paleodictyon fossils. The modern burrows were found around mid-ocean ridge systems in the Pacific and Atlantic Oceans. Although scientists have collected many of the burrows of Paleodictyon nodosum, they have never seen a live one. What a live specimen would look like is widely debated, with the debate being split into two main sides.
The Canadian Film Centre's Worldwide Short Film Festival (WSFF), founded by Brenda Sherwood in 1994, was an annual film festival held over several days in Toronto, Ontario in June, at The Annex-Yorkville area venues; including the Bloor Cinema, the University of Toronto, and the Isabel Bader Theatre, among others. As well as film screenings, the festival hosted parties and the CFC's annual picnic.

Kenneth Craig Macdonald is an American oceanographer and marine geophysicist born in San Francisco, California in 1947. As of 2018 he is professor emeritus at the Department of Earth Science and the Marine Sciences Institute at the University of California, Santa Barbara (UCSB). His work focuses on the tectonics and geophysics of the global mid-oceanic ridge including its spreading centers and transform faults, two of the three types of plate boundaries central to the theory of plate tectonics. His work has taken him to the north and south Atlantic oceans, the north and south Pacific oceans, the Indian Ocean, the Red Sea and the Sea of Cortez, as well as to the deep seafloor on over 50 dives in the research submersible ALVIN. Macdonald has participated in over 40 deep sea expeditions, and was chief- or co-chief scientist on 31 expeditions.
