A massive underwater mountain, otherwise known as a seamount, has been discovered on the floor of the Pacific Ocean off the coast of Guatemala. <\/p>\n
The seamount is most likely a remnant of an extinct volcano, as most seamounts are, according to\u00a0NOAA Ocean Exploration, a federal program that is part of the National Oceanic and Atmospheric Administration.\u00a0At 1,600 meters (5,249 feet) tall, it\u2019s nearly twice the height of Dubai\u2019s Burj Khalifa, the tallest building in the world, according to a news release from\u00a0Schmidt Ocean Institute, a nonprofit organization that advances oceanographic research. <\/p>\n
The discovery of the massive structure \u2014 which covers 14 square kilometers (5.4 square miles) and sits 2,400 meters (7,874 feet) below sea level \u2014 occurred in July during an SOI expedition, which are part of the institute\u2019s efforts to further explore the ocean, using a research vessel known as Falkor (too). The ship is designed to map the seafloor by using a\u00a0multibeam echosounder, which sends out sound waves to the ocean floor in a fan-shaped pattern, then measures the time it takes for the sound to reach the ocean floor and return. <\/p>\n
Tomer Ketter,\u00a0a hydrographer and marine technician with the Schmidt Ocean Institute,\u00a0was also on board, a spokesperson for the institute said, and Ketter confirmed that the seamount was not in any database measuring ocean depths, including the\u00a0General Bathymetric\u00a0Chart\u00a0of the Oceans. <\/p>\n
\u201cA seamount over 1.5 kilometers tall which has, until now, been hidden under the waves really highlights how much we have yet to discover,\u201d said Dr. Jyotika Virmani, executive director of Schmidt Ocean Institute, in the news release. \u201cA complete seafloor map is a fundamental element of understanding our Ocean so it\u2019s exciting to be living in an era where technology allows us to map and see these amazing parts of our planet for the first time.\u201d <\/p>\n
The seamount was discovered 84 nautical miles outside the\u00a0Guatemalan Exclusive Economic Zone. It is estimated that there are more than 100,000 seamounts taller than 1,000 meters (3,280 feet) in the world, but less than one-tenth of a percent have been explored,\u00a0according to NOAA. <\/p>\n
\u201cSeamounts have been explored only relatively recently due to the advent of human\u00a0occupied submersibles and very capable remotely operated vehicles (ROVs),\u201d said\u00a0Les Watling, an emeritus biology professor with the University of Hawaii at Manoa, via email. Watling was not involved with the discovery but was part of a Schmidt Ocean Institute exploration in 2019. <\/p>\n
\u201cThe fact that it is not on the chart is a bit amazing,\u201d Watling said, noting that most of the ocean floor is unexplored. (NOAA estimates less than\u00a025% of the ocean floor\u00a0has been mapped as of 2023.) <\/p>\n
Ocean researchers know where most seamounts \u2014 even ones that haven\u2019t been mapped and explored \u2014 are in the world due to\u00a0satellite radar altimeters, which are used to detect slight differences in the height of the sea by measuring the time it takes a radar pulse sent from a satellite to reach the ocean\u2019s surface and return, Watling said. Above a seamount\u2019s location, the surface of the\u00a0ocean will bulge slightly, allowing for detection of the large underwater mountains. <\/p>\n
About 11 kilometers (6.8 miles) away from where the seamount was mapped, satellite altimetry had shown a modeled seamount, which was most likely this recently mapped seamount, Ketter said, since the pinpoint location of the model may be off due to other land masses in the area. The seamount was not mapped or known before, only its location was predicted from satellite data, he said. <\/p>\n
The recently discovered seamount may be taller than the world\u2019s tallest building, but some have been found to have a height of 4,000 meters (13,123 feet) or more, Watling said. The tallest mountain in the world, Mauna Kea in Hawaii \u2014 which measures more than 10,210 meters (33,500 feet) from base to peak \u2014 started out as a seamount,\u00a0according to NOAA. <\/p>\n
Due to a seamount\u2019s geological formation, the mountains tend to serve as biodiversity hot spots, providing a hard surface to which corals, sponges and other marine invertebrates can cling. <\/p>\n
\u201cSeamounts create distinct ecosystems because the normally sluggish currents above the deep seafloor accelerate as much as 10-fold as they flow around these obstructions,\u201d said\u00a0Tony Koslow, an emeritus research oceanographer with Scripps Institution of Oceanography at the University of California, San Diego, in an email. <\/p>\n
The accelerated currents create the hard rock substrate\u00a0to which invertebrates attach themselves while also drawing in other fauna that feed on food particles swept around by the currents,\u00a0said\u00a0Koslow,\u00a0author of\u00a0\u201cThe Silent Deep: The Discovery, Ecology, and Conservation of the Deep Sea.\u201d\u00a0He was not involved in the discovery. <\/p>\n
Researchers estimate that 15% to 35% of endemic ocean species live in a seamount ecosystem, and migratory species also seek out the structures to breed, feed or seek refuge, according to the\u00a0Pew Charitable Trusts. <\/p>\n
\u201cThe incredible diversity of life on seamounts has been recognized only relatively recently,\u201d Koslow said. \u201cPerhaps the most significant aspect of this discovery is that it confirms that the seafloor is still poorly mapped.\u201d <\/p>\n
