Two mechanisms have been proposed to explain these variations: 1) regional changes in sea-surface productivity influenced seafloor oxygen levels, and\/or 2) the source of intermediate waters changed, with a more proximal, oxygen-rich North Pacific source during the stadials, and a more distal Southern Ocean source during the interstadials. For my Schlanger Ocean Drilling Fellowship research I will test potential causes of enhanced interstadial organic carbon accumulation by tracking changes in intermediate water-mass composition-as recorded at ODP sites 893 and 1017-across interstadials 8 to 14 (~37 to 52 kyr ago) using Nd isotopes from benthic foraminiferal calcite. My preliminary results using coeval fish debris indicate that benthic foraminifera reliably record seawater Nd values and indicate a Southern Ocean intermediate-water source during interstadials.<\/p>\n<p><strong>Biography<\/strong><\/p>\n<p>Unlike many marine scientists, I did not grow up fascinated by the ocean. In fact, I had never even seen the ocean until I attended Hawai\u2019i Pacific University where I ended up earning my bachelor\u2019s degree in marine biology. As a senior, I took geological oceanography as an elective and soon fell in love with paleoceanography. The questions it posed seemed bigger than those considered in marine biology-and more relevant given today\u2019s changing climate. After completing my master\u2019s degree at the University of California, Santa Barbara, I began my Ph.D. at Texas A&amp;M University with Deborah Thomas as my advisor. Eventually, I hope to pursue a career in academia addressing questions from all time scales using the skill sets I am developing. The challenges presented to me by my research are almost as exciting as spending time with my wife Jonna and my daughter Autumn who was born in February 2007.<\/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 : 2.88%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 2.88%;}@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 : 2.88%;margin-left : 2.88%;}}@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":5,"featured_media":0,"parent":19101,"menu_order":59,"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-19509","page","type-page","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.6 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>2007-2008 Schlanger Fellow - Daniel Murphy - U.S. Science Support Program<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/usoceandiscovery.org\/past-schlanger-fellows-old\/2007-2008-schlanger-fellow-daniel-murphy\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"2007-2008 Schlanger Fellow - Daniel Murphy - U.S. Science Support Program\" \/>\n<meta property=\"og:url\" content=\"https:\/\/usoceandiscovery.org\/past-schlanger-fellows-old\/2007-2008-schlanger-fellow-daniel-murphy\/\" \/>\n<meta property=\"og:site_name\" content=\"U.S. Science Support Program\" \/>\n<meta property=\"article:modified_time\" content=\"2022-08-10T07:15:04+00:00\" \/>\n<meta name=\"twitter:label1\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data1\" content=\"4 minutes\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"WebPage\",\"@id\":\"https:\/\/usoceandiscovery.org\/past-schlanger-fellows-old\/2007-2008-schlanger-fellow-daniel-murphy\/\",\"url\":\"https:\/\/usoceandiscovery.org\/past-schlanger-fellows-old\/2007-2008-schlanger-fellow-daniel-murphy\/\",\"name\":\"2007-2008 Schlanger Fellow - Daniel Murphy - U.S. Science Support Program\",\"isPartOf\":{\"@id\":\"\/#website\"},\"datePublished\":\"2016-06-20T18:28:34+00:00\",\"dateModified\":\"2022-08-10T07:15:04+00:00\",\"breadcrumb\":{\"@id\":\"https:\/\/usoceandiscovery.org\/past-schlanger-fellows-old\/2007-2008-schlanger-fellow-daniel-murphy\/#breadcrumb\"},\"inLanguage\":\"en-US\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/usoceandiscovery.org\/past-schlanger-fellows-old\/2007-2008-schlanger-fellow-daniel-murphy\/\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/usoceandiscovery.org\/past-schlanger-fellows-old\/2007-2008-schlanger-fellow-daniel-murphy\/#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Home\",\"item\":\"https:\/\/usoceandiscovery.org\/\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"2007-2008 Schlanger Fellow &#8211;
