In Alaska, CH<sub class="">4</sub> emitted from thermokarst lakes is poised to increase the radiative effect this century but substantial disagreement surrounds the timing and scale. The proposed work brings together Alaskan communities with social and natural scientists to examine changes in inland thermokarst lake environments and effects on Yukon River watershed villages and global climate. </div><div style="margin: 0px; font-stretch: normal; line-height: normal; min-height: 14px;" class=""><br class=""></div><div style="margin: 0px; font-stretch: normal; line-height: normal;" class="">We invite applications for a PhD student at the University of Colorado, Boulder, to be affiliated with the Precision Laser Diagnostics Laboratory. The applicant will be expected to perform biosphere-atmosphere methane flux modeling using trace gas observations. The applicant will also be expected to assist in the field deployment of a dual frequency comb spectrometer in the Arctic and become capable of monitoring and maintaining measurements remotely from the University of Colorado campus. Additional travel to the Arctic to assist with auxiliary measurements and instrument upkeep will be expected (~1 month of travel / year). </div><div style="margin: 0px; font-stretch: normal; line-height: normal; min-height: 14px;" class=""><br class=""></div><div style="margin: 0px; font-stretch: normal; line-height: normal;" class="">The ideal candidate will have a background in engineering and a strong interest in and/or background in biogeochemistry and/or biosphere-atmosphere fluxes of trace gases. The student will be advised by faculty in CU Engineering and at the Cooperative Institute for Research in Environmental Sciences (CIRES) and will additionally work closely with collaborators at the Institute for Arctic and Alpine Research (INSTAAR) and the University of Alaska, Fairbanks. The student’s home department and degree program are negotiable.</div><div style="margin: 0px; font-stretch: normal; line-height: normal; min-height: 14px;" class=""><br class=""></div><div style="margin: 0px; font-stretch: normal; line-height: normal;" class="">Minimum Background:</div><div style="margin: 0px; font-stretch: normal; line-height: normal;" class="">1.
