Yet, many components of its cycle remain unclear, including P uptake and cycling in deep-sea sediments. These are critical, since a significant portion of Earth&#8217;s prokaryotes thrives in deep marine sediments, which are thought to mainly contain low bioavailable P in mineral phases. This suggests that microorganisms possess mechanisms to utilize recalcitrant P pools. The work performed focuses on identifying possible P sources to the deep biosphere, as well as microbial uptake mechanisms using stable oxygen isotope ratios in phosphate and <sup>31<\/sup>P nuclear magnetic resonance spectroscopy on sediment samples collected during IODP 336 Expedition (North Pond).<\/p>\n","protected":false},"template":"","meta":[],"award_type":[9],"_links":{"self":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/awards\/429"}],"collection":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/awards"}],"about":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/types\/award"}],"wp:attachment":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/media?parent=429"}],"wp:term":[{"taxonomy":"award_type","embeddable":true,"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/award_type?post=429"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
