Erebus is one of only a handful of volcanoes worldwide that have lava lakes with readily observable and nearly continuous Strombolian explosive activity. Erebus is also unique in having a permanent convecting lava lake of anorthoclase phonolite magma. Over the years significant infrastructure has been established at the summit of Mt. Erebus as part of the Mount Erebus Volcano Observatory (MEVO), which serves as a natural laboratory to study a wide range of volcanic processes, especially magma degassing associated with an open convecting magma conduit. The PI proposes to continue operating MEVO for a further five years. The fundamental fundamental research objectives are: to understand diffuse flank degassing by using distributed temperature sensing and gas measurements in ice caves, to understand conduit processes, and to examine the environmental impact of volcanic emissions from Erebus on atmospheric and cryospheric environments. To examine conduit processes the PI will make simultaneous observations with video records, thermal imaging, measurements of gas emission rates and gas compositions, seismic, and infrasound data.\n An important aspect of Erebus research is the education and training of students. Both graduate and undergraduate students will have the opportunity to work on MEVO data and deploy to the field site. In addition, this proposal will support a middle or high school science teacher for two field seasons. The PI will also continue working with various media organizations and filmmakers.\nThis dataset contains video taken from a series of cameras that were installed at Shackleton\u0027s Cairn (-77.525337, 167.157509) looking into the lava lake. This dataset contains all such video taken between 2005 and 2011. Camera downlink depended on power at a relay station at the Cones site.

Mount Erebus is Antarctica\u0027s most active volcano that has been in a persistent state of activity for at least the last 35 years. It has a unique geochemistry among the Earth\u0027s active volcanoes and is also unique in hosting a persistent convecting lake(s) of anorthclase phonolite magma in its summit crater. The relative simplicity of the magmatic system, consistency of activity, and accessibility of close-range observation make Erebus attractive as a target for extensive studies. Although the Erebus\u0027 seismicity and eruptive activity and processes are becoming increasingly well understood over years of research, there is a near total lack of understanding its deeper magmatic system. The primary goal of this proposal is to continue supporting the Mt. Erebus Volcano Observatory (MEVO III) improving our current understanding of the Erebus eruptive and non-eruptive magmatic system using an integrated approach from geophysical, geochemical and remote sensing observations. This goal can be grouped into the following fundamental research objectives: (a) to sustain year-round surveillance of on-going volcanic activity primarily using geophysical observatories; (b) to understand processes within the convecting conduit which feeds the persistent lava lakes; and (c) to understand the impact of Erebus eruptive activity upon the Antarctic environment. Continued reliance on students provides a broader impact to this proposed research and firmly grounds this effort in its educational mission.", "east": null, "geometry": null, "keywords": "Antarctica; Cable Observatory; Intracontinental Magmatism; IntraContinental Magmatism; MEVO; Mount Erebus; Photo/video; Photo/Video; Ross Sea; Solid Earth; Volcano", "locations": "Antarctica; Mount Erebus; Ross Sea", "north": null, "nsf_funding_programs": null, "persons": "Kyle, Philip", "project_titles": "Mount Erebus Volcano Observatory III (MEVO III): Conduit Processes and Surveillance", "projects": [{"proj_uid": "p0000488", "repository": "USAP-DC", "title": "Mount Erebus Volcano Observatory III (MEVO III): Conduit Processes and Surveillance"}], "repo": "USAP-DC", "repositories": "USAP-DC", "science_programs": "MEVO", "south": null, "title": "Mount Erebus Volcano Observatory III (MEVO III): Conduit Processes and Surveillance", "uid": "600153", "west": null}]
