Sea surface temperatures dropped by 5-10\u00b0C from 10 to 6 Ma; grasses adapted to arid, low-CO<sub>2<\/sub>\u00a0conditions expanded across the tropics and subtropics. Both are potential responses to declining CO<sub>2<\/sub>. However, CO<sub>2<\/sub>\u00a0estimates for this time period are limited, and most records suggest little to no change through this transition. Are estimates of CO<sub>2<\/sub>\u00a0incorrect and plagued by poor assumptions, or do we not understand the coupling of CO<sub>2<\/sub>\u00a0and climate? Here I propose to address this question with new state-of-the-art records from two marine paleo-CO<sub>2\u00a0<\/sub>proxies. I will assess the history of atmospheric CO<sub>2<\/sub>\u00a0across the Late Miocene through the first multi-proxy, multi-site study.<\/p>\n<p><strong>Biography<\/strong><\/p>\n<p>Born in Rhode Island and raised in Vermont, I developed an appreciation for the environment at an early age. Between my junior and senior undergraduate years, I carried out a summer research project at the Lamont-Doherty Earth Observatory and gained a passion for geochemistry and paleoclimate. My dissertation research focuses on reconstructing atmospheric CO<sub>2<\/sub>\u00a0concentrations over the last ~15 million years using the stable carbon isotope ratios of long-chain alkenones and the mineral remains of coccolithophorid algae. With the Schlanger Fellowship, I will expand on my thesis research by estimating surface ocean pH and atmospheric CO<sub>2<\/sub>\u00a0using boron isotope ratios of planktic foraminifera from the same sediment samples in which I have alkenone-based CO<sub>2<\/sub>\u00a0estimates, providing a direct inter-proxy comparison.<\/p>\n<\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-1{width:66.666666666667% !important;margin-top : 0px;margin-bottom : 20px;}.fusion-builder-column-1 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 0px;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 0px;}@media only screen and (max-width:1024px) {.fusion-body .fusion-builder-column-1{width:66.666666666667% !important;order : 0;}.fusion-builder-column-1 > .fusion-column-wrapper {margin-right : 0px;margin-left : 0px;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-1{width:100% !important;order : 0;}.fusion-builder-column-1 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-flex-container.fusion-builder-row-1{ padding-top : 0px;margin-top : 0px;padding-right : 0px;padding-bottom : 0px;margin-bottom : 0px;padding-left : 0px;}<\/style><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"100-width.php","meta":{"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"jetpack_post_was_ever_published":false,"footnotes":""},"class_list":["post-23422","page","type-page","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.6 -
