As a good rat should, I&#8217;m scurrying around in all the nooks and crannies. Thereby I get to hear many interesting stories. But I don&#8217;t want to report about sailor&#8217;s yarn here, but about facts and figures. I will collect for you some large and small numbers during this expedition to quantify our efforts. I am very curious myself but of course we do not know these answers yet. For the time being, you may join me and calculate, guess, or roll the dice how high each of the respective numbers will be at the end of the journey. The solution will come towards the end of December&nbsp; &#8211; so stay tuned \ud83d\ude09<\/p>\n\n\n\n<p>First something easy to get started. What do you guess?<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>How many shipping containers did we arrive with?<\/li><li>How many tons of fuel does the ship use per day? Hint: the fuel is not only needed for traveling, but also for, e.g., the air conditioning.<\/li><li>How many liters of coffee do we consume?<\/li><li>How often will the station plan (work schedule of when\/which unit goes in the water) need to be changed (as Hannibal from the series &#8220;The A-Team&#8221; used to say, &#8220;I love it when a plan works&#8221;)?<\/li><\/ul>\n\n\n\n<p>Now it gets more specific. Humans and devices work here around the clock. Hence I\u2019ll took a closer look at some of the work.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>How many liters of ethanol do you think is used to preserve biological samples?<\/li><li>How many hours will geochemistry team members stand in the cold lab at 4\u00b0C for their work?<\/li><li>How many oxygen microsensors will break on the seafloor?<\/li><li>How many diving hours will the ROV (a remotely operated diving robot) complete?<\/li><li>And how many kilometers will the AUV (an autonomous diving robot) fly overall?<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"578\" height=\"432\" src=\"https:\/\/www.oceanblogs.org\/SO295-MiningImpact\/wp-content\/uploads\/sites\/91\/2022\/12\/Wilma_on_ethanol_canister.jpg\" alt=\"\" class=\"wp-image-90\" \/><figcaption><em>Wilma on an ethanol canister.

However, I already know for sure that when I pay the next fuel bill I will be happy that it is not for a ship.<\/p>\n\n\n\n<p>Have fun with the riddles!

Wie es sich f\u00fcr eine gute Ratte geh\u00f6rt husche ich dabei in alle Ecken und Winkel. Dabei bekommt man viele interessante Geschichten zu h\u00f6ren. Aber ich will hier nicht \u00fcber Seemannsgarn berichten, sondern \u00fcber Fakten und Zahlen. Ich werde f\u00fcr Euch einige gro\u00dfe und kleine Zahlen \u00fcber diese Expedition in Erfahrung bringen, damit man mal einen Eindruck bekommt, was f\u00fcr ein Aufwand dahinter steckt. So richtig k\u00f6nnen wir das nat\u00fcrlich erst nach Abschluss der Arbeiten wissen. Bis dahin k\u00f6nnt ihr, mit mir zusammen, gerne selber rechnen, raten oder w\u00fcrfeln wie hoch die jeweilige Zahl am Ende der Reise sein werden. Keine Sorge, die Aufl\u00f6sung kommt gegen Ende Dezember \ud83d\ude09<\/p>\n\n\n\n<p>Erstmal was Leichtes zum Eingew\u00f6hnen.
