The location and geometry of the magmatic plumbing from vent to lower crust system remain poorly constrained, particularly below 1 km depth. The style and causes for changes in volcanic and magmatic activity over the short term (minutes to hours) and on the decadal scale remains enigmatic. Two decades of campaign and continuous GPS data on Ross Island provide insights into the longer term dynamics of both, Ross Island growing within the Terror Rift, and Erebus\u0027 deeper magmatic system. We organized and analyzed all existing GPS data for Ross Island, and interpreted anomalies in the resulting time series. The GPS data were consistently processed and interpreted. We generated position time series in a consistent reference frame and make the results available to the community. We find several periods of volcanic transient deformation in the time series, indicating times of inflation before 2004, deflation from 2004-2011 and renewed inflation from October 2020 until June 2021.", "east": 169.6, "geometry": "POINT(167.55 -77.5)", "instruments": null, "is_usap_dc": true, "keywords": "Ross Island; TECTONICS; USAP-DC; Amd/Us; AMD; CRUSTAL MOTION; USA/NSF; FIELD SURVEYS", "locations": "Ross Island", "north": -77.1, "nsf_funding_programs": "Antarctic Earth Sciences; Antarctic Instrumentation and Facilities", "paleo_time": null, "persons": "Grapenthin, Ronni", "platforms": "LAND-BASED PLATFORMS \u003e FIELD SITES \u003e FIELD SURVEYS", "repo": "USAP-DC", "repositories": "USAP-DC", "science_programs": null, "south": -77.9, "title": "Collaborative Research: Multi-Parameter Geophysical Constraints on Volcano Dynamics of Mt.

Mount Erebus is Antarctica?s 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.

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.\u003cbr/\u003e\u003cbr/\u003eBroader impacts: \u003cbr/\u003eAn important aspect of Erebus research is the education and training of students.

Paleomagnetic data (directions of ancient geomagnetic fields obtained from rocks) play an important role in a variety of geophysical studies of the Earth, including plate tectonic reconstructions, magnetostratigraphy, and studies of the behavior of the ancient geomagnetic field (which is called paleo-geomagnetism). Over the past four decades the key assumption in many paleomagnetic studies has been that the average direction of the paleomagnetic field corresponds to one that would have been produced by a geocentric axial dipole (GAD) (analogous to a bar magnet at the center of the Earth), and that paleoinclinations (the dip of magnetic directions from rocks) provide data of sufficient accuracy to enable their use in plate reconstructions. A recent re-examination of the fundamental data underlying models of the time averaged field has shown that the most glaring deficiency in the existing data base is a dearth of high quality data, including paleointensity information, from high latitudes. This project will undertake a sampling and laboratory program on suitable sites from the Mt.
