Collectively, results from these studies have major implications for understanding past functioning of the Earth system. The barite accumulation rates indicate that biological productivity of the oceans and carbon export via the biological pump can both change rapidly with climatic change; and provide feedback mechanisms that modulate climate. For example, during the mid-Cretaceous, ocean productivity may influence climate by regulating the partitioning of carbon dioxide between the ocean and the atmosphere \u2013 i.e., enhanced export production may have provided a negative feedback to high atmospheric CO<sub>2<\/sub>\u00a0that reduced effects of greenhouse warming.<\/p>\n<p><strong><em>Dr. Paytan\u2019s research relies on sediments collected by the Deep Sea Drilling Program and the Ocean Drilling Program, with emphasis on those spanning the Cretaceous and Paleocene-Eocene Thermal Maximum.<\/em><\/strong><\/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 class=\"fusion-layout-column fusion_builder_column fusion-builder-column-2 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><style type=\"text\/css\">@media only screen and (max-width:1024px) {.fusion-title.fusion-title-2{margin-top:10px!important;
