Since nodule mining creates two main disturbances, removal of the surface sediments and the nodule habitat where nodules are collected as well as blanketing of the surrounding unmined seafloor, both impact types will be investigated in the two areas. <\/p>\n\n\n\n<p>Within these, different sites representative for gradients and variability of the disturbances will be identified, particularly addressing the impact due to varying thickness of the sediment blanket. In addition, the restoration experiment, which was started during SO268, consisting of artificial hard substrates as substitutes of manganese nodules, will be sampled. Natural variability is addressed by continuing the sampling of reference sites established in both license areas<\/p>\n\n\n\n<p>+++ deutsche Fassung<\/p>\n\n\n\n<p> Expedition SO295 <br>31.10.2022 &#8211; 24.12.2022<\/p>\n\n\n\n<p>Die Fahrt baut auf den Ergebnissen des <a href=\"https:\/\/miningimpact.geomar.de\/de\/home\" data-type=\"URL\" data-id=\"https:\/\/miningimpact.geomar.de\/de\/home\">JPIOceans Verbundprojekts MiningImpact 2 <\/a>auf und schlie\u00dft an die Expedition SO268 im Februar-Mai 2019, auf der die Umwelthintergrunddaten in den beiden Arbeitsgebieten in den Lizenzgebieten Deutschlands und Belgiens in der CCZ (NE Pazifik) erhoben wurden, sowie die im M\u00e4rz-Mai 2021 durchgef\u00fchrte Expedition IP21, auf der eine unabh\u00e4ngige wissenschaftliche Beobachtung des ersten industriellen Knollenkollektortests durchgef\u00fchrt wurde, an. Durch SO295 wird der erste wichtige Zeitpunkt in der Bewertung der Umweltauswirkungen ca. 1,5 Jahre nach dem Tiefseebergbautest erhoben. In beiden Gebieten werden jeweils die beiden durch den Knollenkollektortest induzierten Arten der Umweltst\u00f6rung untersucht, n\u00e4mlich die Entfernung der Sedimentoberfl\u00e4che inklusive des Knollenhabitats, sowie die Bedeckung des umgebenden Meeresbodens und seiner Fauna durch die Ablagerung der aufgewirbelten Sedimentwolke. Innerhalb der Areale werden Stationen identifiziert, die repr\u00e4sentativ f\u00fcr Gradienten und Variabilit\u00e4t der Sch\u00e4digung sind, insbesondere in Hinsicht auf unterschiedlich m\u00e4chtige Sedimentablagerungen.
