Clarification from the agency

Open to all qualified candidates who meet the eligibility requirements of the Mendenhall Postdoctoral Research Fellowship. Because this fellowship is a U.S. Government position, preference must be given to U.S. citizens. Citizens of other nations may be considered under certain circumstances, i.e., when there are no qualified U.S. citizen applicants available. In those instances, the USGS may consider making an offer to a non-citizen provided applicable laws and regulations are followed.

Mendenhall Research Fellowship - Research Opportunity #: 19-16. Developing a mixed-volatile solubility model for common hazardous magmas

Every year staff members of the USGS are called upon to respond to and assess unrest at active volcanoes in the U.S. or internationally, and responses typically include measurements of the amounts and types of gases being released over time and with changing styles of unrest. Such efforts continue to improve the precision and breadth of volcanic gas data, but often the question remains: What do these signals mean for the processes happening in upper crustal magma reservoirs and sub-volcanic conduits? This shortcoming stems to a large degree from the limited understanding of the combined solubilities of sulfur species with H2O and CO2 at the oxidized conditions of most subduction zone magmas.

This opportunity would address that deficiency by developing and executing a series of high temperature, moderate-to-high pressure laboratory experiments to determine the solubilities of S-species mixed with H2O and CO2 in one or more subduction-related compositions, and then integrating those and literature results to develop a mixed-volatile solubility model. The experimental portion of the effort would be conducted in the Volcano Science Center's Magma Dynamics Lab, Menlo Park, California. The Mendenhall Fellow would then use those results and the published solubility literature to develop an integrated H2O-CO2-S solubility model, the comprehensiveness of which would depend on the breadth of experimental results. Components of the model could include the ability to calculate gas composition from melt composition, and vice versa, at specified pressures, temperatures, and oxidation states, and possibly the ability to calculate changes in exsolved gas composition along different magma ascent paths, both in an open and a closed system (gas escapes versus stays with melt), and the effects of gas fluxing at various proportions and with a range of influx compositions through a static magma column. Ideally, the model would be accessible as a software application, in addition to being released in one or more scientific publications.

Proposed Duty Station: Menlo Park or Moffett Field, California

Areas of Ph.D: Igneous petrology or volcanic gas geochemistry with experience in high temperature/pressure experiments, or related fields (candidates holding a Ph.D. in other disciplines but with knowledge and skills relevant to the Research Opportunity may be considered).

Qualifications: Applicants must meet one of the following qualifications for: Research Geologist.
(This type of research is performed by those who have backgrounds for the occupations stated above. However, other titles (see link below) may be applicable depending on the applicant's background, education, and research proposal. The final classification of the position will be made by the Human Resources Specialist.)

Mendenhall Basic Qualification Requirements:
https://www.usgs.gov/centers/mendenhall/basic-qualification-requirements-0

Physical/Environmental Demands:

  1. The primary work environment is in a laboratory containing custom-built equipment to raise samples to high temperatures and pressures. Preparing experiments involves sitting at a desk, looking through a microscope, and manipulating small (mm) sized objects using tweezers, micro-welders, and high-precision balances. Performing an experiment can involve turning wrenches at chest or shoulder height, raising 20 lb. objects to shoulder level, or 40 lb. objects to chest level, and positioning these precisely. Analyzing experimental products involves operating an electron-microprobe from a sitting position for hours at a time in a generally darkened room through a computer console and various monitors. Preparing results for presentation and publication involves sitting at a desk in an office using a computer and various drafting and text editing programs.
  2. Work involves exposure to moderate risks and discomfort including inadvertent pinches or abrasions during tool use, potential for dropping heavy objects onto feet, and local burns if not careful around high-temperature furnaces.Work requires special safety precautions, protective clothing and equipment, training, and adherence to operating protocols.

Qualifications

General Information

The Mendenhall Research Fellowship Program provides an opportunity for postdoctoral fellows to conduct concentrated research in association with USGS scientists, often as a final element to their formal career preparation. The Program also provides: 1) research experiences that enhance the scientific stature and credentials of the Fellows; and 2) scientific expertise to assist in the implementation of the USGS Strategic Plan and the science strategy of its programs. Mendenhall Fellows are expected to publish their results in peer-reviewed scientific outlets.

Eligibility Requirements

In order to be considered for these opportunities, candidates must:

(1) have successfully completed a Ph.D. in a field related to the described Research Opportunity no earlier than October 1, 2015 (5 years before the announcement opening date); OR

(2) if close to completion, have all Ph.D. requirements completed and must submit proof of completion prior to receiving an official start date;

(3) meet the qualification requirements described in the Research Opportunity. The research proposal submitted must demonstrate that the applicant is equipped with the knowledge, skills, and abilities to successfully perform the duties for the specific Research Opportunity.

Start Date and Completion of PhD:

It is anticipated that this position will start no later than March 2022. The person selected must have all PhD requirements completed and MUST submit proof of completion prior to receiving an official start date. Exceptions may be made for a later start date on a case-by-case basis.
