In a groundbreaking study, scientists at the Scripps Institution of Oceanography have discovered nearly 20,000 ancient volcanoes beneath the ocean. Using satellite data, the researchers detected these submerged volcanic structures, known as seamounts, improving our understanding of the mysterious world beneath the waves.
The Role of Satellite Data in the Discovery of Ancient Volcanoes Beneath the Ocean
The scientists utilized data from the CryoSat-2 satellite from the European Space Agency and SARAL. This was a collaboration between Indian and French space agencies. Moreover, this innovative approach allowed them to detect 19,325 seamounts on the ocean floor, showcasing the potential of satellite technology in uncovering hidden geological wonders.
Seamounts have a significant impact on the ocean and its ecosystems, making it vital to study, map, and classify them. Previously, these oceanic structures were detected using sonar, which is only effective when a ship is nearby. However, satellite data has now paved the way for more comprehensive mapping and understanding of these fascinating formations.
Comparing Satellite and Sonar Data
The use of satellite data has proven to be more revealing than sonar data. It unveiled numerous smaller seamounts that were previously undetected. Sonar relies on sound waves bouncing off the seabed. Satellite technology uses altimetry to measure changes in sea surface, enabling more accurate detection of seamounts.
With the addition of the newly discovered seamounts, the total number of cataloged oceanic volcanoes has risen to 43,454. The 2021 estimate suggested the existence of around 55,000 seamounts. This recent discovery has prompted researchers to reassess that figure. Furthermore, there was a belief that thousands more volcanoes may be waiting to be on the ocean floor as discoverable things.
Implications for Future Research about Ancient Volcanoes Beneath the Ocean
The identification of these ancient volcanoes beneath the ocean has numerous implications for future research. Not only does it enhance our understanding of the relationship between tectonic plates and volcanoes, but it also demonstrates the potential for further discoveries with advancements in data resolution.
