texas a&m to establish premier stable isotope capabilitiesnov 28 2016$1 million grant enables purchase of two highly technical instrumentscollege station - a $1 million grant - stable isotope partnership for ecology environment and energy research - will help texas a&m develop a unique shared mass spectrometry core facility this will be a useful new approach for predicting petroleum maturation and more cost effective exploration and understanding of biogeochemical processes researchers said as well as many other discoveries funding was provided by the texas a&m university research development fund which makes strategic investments that support the total texas a&m research enterprise and catalyze new ventures the stable isotopes for biosphere science laboratory which will soon be home to a compound-specific mass spectrometer system the development of this premier capability is possible through the partnership of the stable isotopes for biosphere science laboratory or sibs in the college of agriculture and life sciences and the stable isotope geosciences facility or sigf in the college of geosciences "this will provide technology at the forefront of ecology environment and energy research " said dr thomas boutton regents professor and texas a&m agrilife senior faculty fellow the key team members are a part of several texas a&m multidisciplinary faculties and have developed collaborative relationships with a diverse cross-section of faculty staff and graduate students in texas a&m agrilife research and five colleges on campus leading the efforts in the sibs lab are faculty from the department of ecosystem science and management including boutton dr jason west dr jason vogel and dr ayumi hyodo other faculty on the lead team and sigf directors are dr ethan grossman geology department; dr brendan roark geography department and dr niall slowey oceanography department "the funds will primarily support the purchase of new instrumentation including a gas chromatography combustion/pyrolysis isotope ratio mass spectrometer and a high resolution isotope ratio mass spectrometer for clumped isotopes " west said "this expansion will give texas a&m university research capacity in stable isotope ratio analysis that is unmatched in the state and region" the compound-specific mass spectrometer system to be housed in the sibs lab separates and identifies chemical compounds in samples then measures the stable carbon nitrogen oxygen or hydrogen isotope ratios of those compounds "this system will provide cutting-edge capabilities to utilize individual molecule isotope ratios as fingerprints of biosphere geosphere hydrosphere and atmosphere processes " west said "some potential applications include reconstructing past climates from hydrocarbons in soil and sediments identifying soil microbes and their biogeochemical functions and unraveling food web structure" the clumped isotope mass spectrometer to be housed in the sigf measures the relative abundance of molecules with two rare isotopes this ratio in carbonate rocks and minerals is temperature-dependent and therefore being used as a new technique in geothermometry reconstruction of the precise temperatures at which carbonate rocks shells or foraminifera were formed will be useful in soil science geology and oceanography hyodo said "in addition this instrumentation would also provide triple oxygen isotope analysis an emerging tracer for hydrologic and atmospheric research " she said "to our knowledge neither of the analytical capabilities are available in texas research institutions " hyodo said "to facilitate use among the texas a&m community we will be hosting joint seminars focused on the new applications training through a methods course and an international symposium" both stable isotope mass spectrometer systems are expected to be available for on- and off-campus users in 2018 she said ### more information can be found on the sibs lab at http://sibstamuedu and more information on the sigf can be found at http://bitly/2fdcojuu dr ethan grossman; professor michel t halbouty chair (top) dr brendan roark; associate professor geography (middle) dr niall slowey; professor oceanography (bottom)
