There were <strong>15 containers<\/strong>.<\/li><li>Approximately how much diesel did we use per day? About <strong>10 tons of diesel<\/strong> were consumed daily during this expedition.<\/li><li>How much coffee was consumed during this trip? We drank about <strong>2200 litres of coffee<\/strong>. That sounds a lot at first, but distributed over 72 people and 7 weeks, that&#8217;s not so much coffee at all (about 3 cups a day per person).<\/li><li>How often did the station plan (the work schedule that tells when which equipment goes into the water) have to be changed? Our expedition leader had to change the station plan a total of about <strong>50 times<\/strong> after he had created it.<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1223\" height=\"1635\" src=\"https:\/\/www.oceanblogs.org\/SO295-MiningImpact\/wp-content\/uploads\/sites\/91\/2022\/12\/Wilma_meets_stationplan.jpg\" alt=\"\" class=\"wp-image-192\" \/><figcaption><em>Wilma reading the station plan.

The biologists used a total of <strong>750 litres of ethanol <\/strong>to preserve their samples.&nbsp;<\/li><li>How many hours did the geochemistry working group spend in the 4\u00b0C laboratory? The geochemists spent about <strong>220 hours in the cold<\/strong>. Brrr. And they said we were going to the tropics!

That&#8217;s painful &#8211; but with all the nodules on and in the seabed, it can&#8217;t be prevented.<\/li><li>How many diving hours did the ROV (a remotely operated diving robot) complete? The ROV spent around <strong>250 hours underwater<\/strong>. I can&#8217;t hold my breath that long.<\/li><li>And how many kilometres did the AUV (an autonomous underwater vehicle) &#8220;fly&#8221; along the seabed? AUV &#8220;Tiffy&#8221; travelled <strong>1280 kilometres<\/strong> all alone in the deep sea. A real loner, this Tiffy.

And how large is the data volume of the collected video material? The OFOS <strong>took exactly 17,001 photos<\/strong> and <strong>recorded about 10 terabytes of video material<\/strong>. Quite a lot! At the same time, this is only a tiny fraction of the huge area of the seabed.<\/li><li>How many photos did journalist Kim Kalvelage take on the trip? He <strong>pressed the shutter release about 10,000 times<\/strong>. It won&#8217;t be easy to choose a few highlights.<\/li><\/ul>\n\n\n\n<p>Did you guess everything right?<\/p>\n\n\n\n<p>Merry Christmas and a happy new year 2023!<\/p>\n\n\n\n<p><strong><em>Deutsche Version<\/em><\/strong><\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Zahlen der Fahrt &#8211; ein kleines R\u00e4tsel (Teil 2)<\/strong><\/p>\n\n\n\n<p><em>Mirja Bardenhagen, Marine Rohstofferkundung &#8211; Bundesanstalt f\u00fcr Geowissenschaften und Rohstoffe in Hannover, Deutschland<\/em><\/p>\n\n\n\n<p>Hallo, ich bin es wieder Wilma.
