![]() ![]() Important volcanic episodes include: astonishingly voluminous mafic and felsic volcanic deposits associated with the Jurassic break-up of Gondwana the construction and progressive demise of a major Jurassic to Present continental arc, including back-arc alkaline basalts and volcanism in a young ensialic marginal basin Miocene to Pleistocene mafic volcanism associated with post-subduction slab-window formation numerous Neogene alkaline volcanoes, including the massive Erebus volcano and its persistent phonolitic lava lake, that are widely distributed within and adjacent to one of the world's major zones of lithospheric extension (the West Antarctic Rift System) and very young ultrapotassic volcanism erupted subglacially and forming a world-wide type example (Gaussberg). Each is described in terms of (1) the volcanology and eruptive palaeoenvironments (2) petrology and origin of magma and (3) active volcanism, including tephrochronology. The volume is an amalgamation of in-depth syntheses, which are presented within distinctly different tectonic settings. When I'm not teaching, I enjoy competing in triathlons and marathons and spending time with my wife and two daughters.This memoir is the first to review all of Antarctica's volcanism between 200 million years ago and the Present. And then being fortunate enough to skype with students from the IPY Oslo Conference the following year really started a continuous dialog around our community that I am working to expand. By sharing the Erebus expedition while actually living and working on an active volcano has excited my teaching and my students. My goal is to connect my district and community with the current issues in cryosphere research that already affects us all.īeing able to teach children current, real-life science and make those connections between education and research has been a wonderful experience for me. ![]() The students have the imaginations and the energy needed to tackle STEM issues in an ever shrinking world. I feel it is critical to our future that these children become motivated in understanding how the world works and the challenges they will face in the near future. I have been given the opportunity to visit and speak at every school in our district and I continue to be amazed at the positive response from the kids! They are excited to learn about the polar regions and the science that is being conducted there. I am so happy and proud of our district and students. John Wood teaches middle school science at Talbert Middle School in Fountain Valley, California. The West Antarctic rift system is one of the major rifts in the world and home to many volcanoes although only a handful are currently active. Erebus and the East African volcanoes are situated in places where the earth’s crust and tectonic plates are being pulled apart by forces creating rift valleys. Mount Erebus has a summit elevation of 3,794 meters (12,448 ft) and the rocks resemble those at the volcanoes Kilimanjaro and Kenya in East Africa. Mount Erebus is located on Ross Island, which is also home to three inactive volcanoes (Bird, Terror, and Terra Nova) as well as McMurdo Station, the largest research station in Antarctica and the center of operations for the US Antarctic Program. Even in summer winds can be over 100 mph. They slept in tents in temperatures that reached as low as -40 F (-40 C) but had a 16 by 24 foot hut to live in and shelter from the stormy weather. Erebus Volcano Observatory, a research station situated 3400 meters (12,451 ft) high near the summit crater of the volcano. The 11-person team lived and worked at the Mt. They continued monitoring emissions of gases and aerosols and maintained instruments to monitor the weather and deformation of the volcano. This allowed the team to cat-scan the inside of the volcano. Then they set off explosion at 14 sites on and around the volcano using dynamite and other materials to create seismic waves that were recorded by the seismometers. ![]() The highest is Mount Sidley a dormant volcano that rises 4,181 4,285 m high. The team installed 100 seismometers to supplement 32 already installed on the volcano. Erebus is also the southernmost active volcano on Earth and the second-highest volcano in Antarctica. A second seismic experiment looked at the deeper crustal structure under the volcano to understand where the magma is generated. Most of the team members undertook a major seismic experiment which imaged the conduit (pipe) which feeds molten magma to the permanent lake of lava in the crater of Erebus volcano. The team from NM Tech worked at the summit of the volcano for over four weeks during the austral summer of 2008-09. Erebus is the southernmost active volcano on Earth and the most active in Antarctica. ![]()
