Scientists Reconstruct Impact of Seafloor Volcanic Eruption

we gather from studying the 2008 Chaitén eruption is relevant for coastal and island volcanoes globally.”“Approximately half of the earth’s volcanoes are islands or located near coasts, like Chaitén,” said Schmidt Ocean Institute’s Executive Director, Dr. Jyotika Virmani. “It is amazing that as recently as 2008, this volcanic eruption wasn’t predicted. Understanding volcanic activity and its footprint on the offshore ecosystem provides data to more readily predict the frequency and severity of events, which is essential to saving lives and cultures

ROV SuBastian prepares to take a core sample of seafloor contents. Dive 679 took place off the coast of Northern Chilé with the research team aiming to characterize the microbial and macrofaunal communities in the surrounding areas of the Atacama Trench. The primary objective of this dive was to explore the ridge area for methane seeps and collect samples (push cores, water, rock, and animal samples) at seepage sites.

Atacama Desert. The animal samples will be kept at the Universidad Arturo Prat Museo del Mar in Iquique and the National History Museum in Santiago, Chile, following identification and characterization.“Finding such cold-water seeps using nothing but mapping data is wonderful,” said Dr. Jyotika Virmani, Executive Director of the Schmidt Ocean Institute, “There was a chance that the science team would not locate these amazing deep-water, chemosynthetic environments. With further analysis, bacteria from these seeps may provide new insights into how life persists in the darkness, offering

Josh O’Brien (Marine Technician) and Annabelle Adams-Beyea (Student, Montana State University) remove Niskin bottles from the CTD rosette prior to a re-deployment. Highly sensitive oxygen sensors were mounted on the CTD rosette which were used to make measurements of the extent of the oxygen minimum zone. "CTD" stands for conductivity, temperature, and depth, and refers to a package of electronic devices used to detect how the conductivity and temperature of water changes relative to depth.

measure low levels of oxygen in the ocean due to sampling limitations. This expedition was an exciting test of novel technology that pushed a critical boundary of detection and highlights the need for continuing innovation in Ocean research,” said Schmidt Ocean Institute Executive Director Dr. Jyotika Virmani. “The suite of technologies developed by Dr. Pachiadaki and her colleagues open the doors to an increased understanding of microbial processes and phenomenon in these expanding Oxygen Minimum Zones.”Gerardo García (Research Technician, Universidad de Concepción) and

Ecuador has called for a precautionary pause on deep-sea mining. “These finely detailed maps created with state-of-the-art technology are exceptional for the area they cover and the seafloor complexity they reveal,” said Schmidt Ocean Institute’s executive director, Dr. Jyotika Virmani. “In addition to increasing the scientific knowledge of the region, it is wonderful to know they will be used in Ecuador's management of their own marine resources. Schmidt Ocean Institute is committed to stewarding new technologies that allow us to fully map and characterize the seafloor

higher-resolution maps will guide scientific research and future discoveries, while offering improved understanding of geological processes.“A seamount over 1.5 kilometers tall which has, until now, been hidden under the waves really highlights how much we have yet to discover,” said Dr. Jyotika Virmani, executive director of SOI.“ A complete seafloor map is a fundamental element of understanding our Ocean so it’s 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!”(Photo: Schmidt Ocean Institute)Mapping

.”“This is the fourth hydrothermal vent field discovery made by scientists on our new research vessel Falkor (too) since March, in addition to the discovery in August of a new animal ecosystem living under hydrothermal vents,” said Schmidt Ocean Institute Executive Director Dr. Jyotika Virmani. “With 75% of the seafloor still to map, finding this new vent field shows how much we still have to learn about our planet and those who live on it. I am continually amazed by the otherworldly beauty of our seafloor and look forward to uncovering more.&rdquo
