Arctic Tundra Biogeochemistry Postdoctoral Scholar
Arctic Tundra Biogeochemistry Postdoctoral Scholar - 84599
Organization: AU-Earth & Environmental Sciences
Berkeley Lab’s Earth & Environmental Sciences Division (https://eesa.lbl.gov/) has an opening for a Arctic Tundra Biogeochemistry Postdoctoral Scholar. This is an exciting opportunity for a Postdoctoral scientist to advance understanding of the effects of temperature on permafrost ecosystems and soil carbon cycling. You will work with a team of scientists studying ecosystem response to warming in Alaska as part of the Next Generation Ecosystem Experiment - Arctic project (NGEE, https://ngee-arctic.ornl.gov/). You will develop and implement a novel soil warming experiment on the Seward Peninsula and/or Barrow, Alaska, and measure the impact of the treatments on soil CO2 and CH4 fluxes, soil nitrogen cycling, permafrost depth, and other properties and states. They will improve the design (based on our successful prototype and will have technical assistance), manage the instrumentation of the site for warming and microclimate monitoring, carry out measurement campaigns, and write papers based on the experiment. As time allows, this role may elect to work with other NGEE teams on eddy covariance flux measurements, Arctic shrub distributions, and other research. The successful candidate will be largely responsible for running the warming experiment, archiving data, and collaborating with scientists from other disciplines who can use the warming experiment and its data. For example, data from the experiment will be used by NGEE to develop empirical assessments and test models. The successful candidate will spend a significant amount of time in Alaska. They will work with Margaret Torn, William J. Riley, and others.
The ideal position start time is Spring 2018 and is a fulltime, one-year term appointment with the possibility of renewal up to four (4) years based on performance, funding, and continued operational needs. To be considered, please provide the following in PDF form:
• One-two page application letter describing research interests and relevant experience.
• Contact information for three references.
• One-two publications.
What You Will Do:
• Develop field warming experiment in Alaska.
• Maintain experiment in good working order.
• Measure effects of warming on the ecosystem, including plot-scale trace gas flux, NDVI, and albedo.
• Publish papers and give presentations on the results of the warming experiment in context of Arctic warming.
• Conduct field work in Alaska.
• Analyze data with appropriate statistics.
• Perform rigorous QA/QC on data and archive data with NGEE to share data with NGEE team.
• Interact with modeling team to help evaluate and improve soil biogeochemical models.
• Contribute to group presentations, progress reports, renewal proposal, and other NGEE activities.
Additional Responsibilities as needed:
• Compare observations to model output.
• Participate in modeling the results of the experiment and the potential for Arctic ecosystem-climate feedbacks.
• Synthesize and publish our chamber-based data set of Arctic greenhouse gas fluxes and/or soil carbon.
• Contribute to other aspects of the team’s work, depending on interest, such as determining controls of shrub distributions or eddy covariance estimates of ecosystem fluxes.
What Is Required:
• Recent PhD(within 2 years) in ecology, earth sciences, biometeorology or related field.
• Expertise in biogeochemistry and experience conducting fieldwork.
• Experience conducting research on soil biogeochemistry, Arctic soils, effect of climate change on Arctic ecosystems or demonstrated interested Arctic biogeochemistry.
• Technical aptitude with field measurements/instruments or relevant instruments such as microclimate monitoring, flux measurements or similar.
• Record of publishing and presenting at scientific conferences.
• Ability to work with large data sets and to identify and apply appropriate statistical analyses.
• Ability to work effectively in a physically demanding job and to work safely in remote harsh environments.
• Ability to work both independently and as part of team.
• Record of producing rigorous influential scientific results.
Additional Desired Qualifications:
• Previous backcountry experience in cold climates.
• Ability to carry and use heavy field instruments.
• Experience conducting team research in the field.
• Experience with data loggers, soil microclimate monitoring, modeling or statistical analysis relevant to field experiments.
The posting shall remain open until the position is filled, however for full consideration, please apply by close of business on July 31, 2018.
• This is a full time, 1 year, postdoctoral appointment with the possibility of renewal based upon satisfactory job performance, continuing availability of funds and ongoing operational needs. You must have less than 4 years paid postdoctoral experience. Salary for Postdoctoral positions depends on years of experience post-degree.
• Full-time, M-F, exempt (monthly paid) from overtime pay.
• This position is represented by a union for collective bargaining purposes.
• Salary will be predetermined based on postdoctoral step rates.
• This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.
• Work will be primarily performed at: Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA.
