Andrea Koschinsky was involved in the investigation of the role that the mineralogy and redox chemistry of the nodules may play in the unique process in which arrays of nodules produce enough potential to split seawater into oxygen and hydrogen. This exciting discovery will have important\u00a0implications for the way in which future deep-sea mining will develop, the question of where and how aerobic life on Earth has begun, and what potential these nodule &#8220;rock batteries&#8221; may have.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/andrea-koschinsky.org\/wp-content\/uploads\/2024\/07\/Manganese-nodules-on-ferromanganese-crust-slice-photo.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/andrea-koschinsky.org\/wp-content\/uploads\/2024\/07\/Manganese-nodules-on-ferromanganese-crust-slice-photo-1024x683.jpg\" alt=\"\" class=\"wp-image-2459\" srcset=\"https:\/\/andrea-koschinsky.org\/wp-content\/uploads\/2024\/07\/Manganese-nodules-on-ferromanganese-crust-slice-photo-1024x683.jpg 1024w, https:\/\/andrea-koschinsky.org\/wp-content\/uploads\/2024\/07\/Manganese-nodules-on-ferromanganese-crust-slice-photo-300x200.jpg 300w, https:\/\/andrea-koschinsky.org\/wp-content\/uploads\/2024\/07\/Manganese-nodules-on-ferromanganese-crust-slice-photo-768x512.jpg 768w, https:\/\/andrea-koschinsky.org\/wp-content\/uploads\/2024\/07\/Manganese-nodules-on-ferromanganese-crust-slice-photo-1536x1024.jpg 1536w, https:\/\/andrea-koschinsky.org\/wp-content\/uploads\/2024\/07\/Manganese-nodules-on-ferromanganese-crust-slice-photo-2048x1366.jpg 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>","protected":false},"excerpt":{"rendered":"<p>A new study by Prof. Andrew Sweetman and coauthors published in Nature Geoscience (Evidence of dark oxygen production at the abyssal seafloor)\u00a0has shown how oxygen is produced in the presence of ferromanganese nodules in complete darkness at the seafloor 4,000<\/p>","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"advanced_seo_description":"","jetpack_seo_html_title":"","jetpack_seo_noindex":false},"tags":[],"news-category":[],"class_list":["post-2457","news","type-news","status-publish","hentry"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/andrea-koschinsky.org\/pt\/wp-json\/wp\/v2\/news\/2457","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/andrea-koschinsky.org\/pt\/wp-json\/wp\/v2\/news"}],"about":[{"href":"https:\/\/andrea-koschinsky.org\/pt\/wp-json\/wp\/v2\/types\/news"}],"author":[{"embeddable":true,"href":"https:\/\/andrea-koschinsky.org\/pt\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/andrea-koschinsky.org\/pt\/wp-json\/wp\/v2\/comments?post=2457"}],"version-history":[{"count":3,"href":"https:\/\/andrea-koschinsky.org\/pt\/wp-json\/wp\/v2\/news\/2457\/revisions"}],"predecessor-version":[{"id":2461,"href":"https:\/\/andrea-koschinsky.org\/pt\/wp-json\/wp\/v2\/news\/2457\/revisions\/2461"}],"wp:attachment":[{"href":"https:\/\/andrea-koschinsky.org\/pt\/wp-json\/wp\/v2\/media?parent=2457"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/andrea-koschinsky.org\/pt\/wp-json\/wp\/v2\/tags?post=2457"},{"taxonomy":"news-category","embeddable":true,"href":"https:\/\/andrea-koschinsky.org\/pt\/wp-json\/wp\/v2\/news-category?post=2457"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
