Copepods are small aquatic crustaceans and are one of the most numerous groups in aquatic plankton communities. The objective of the experiments is to verify if ocean alkalinity enhancement affects the physiology of the organisms.<\/p>\n\n\n\n<figure class=\"wp-block-gallery columns-2 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><ul class=\"blocks-gallery-grid\"><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"3648\" height=\"2736\" src=\"https:\/\/www.oceanblogs.org\/oceannets\/wp-content\/uploads\/sites\/78\/2022\/05\/Picture-2.jpg\" alt=\"\" data-id=\"247\" data-link=\"https:\/\/www.oceanblogs.org\/oceannets\/?attachment_id=247#main\" class=\"wp-image-247\" \/><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img loading=\"lazy\" decoding=\"async\" width=\"3648\" height=\"2736\" src=\"https:\/\/www.oceanblogs.org\/oceannets\/wp-content\/uploads\/sites\/78\/2022\/05\/Picture-3.jpg\" alt=\"\" data-id=\"248\" data-link=\"https:\/\/www.oceanblogs.org\/oceannets\/?attachment_id=248#main\" class=\"wp-image-248\" \/><\/figure><\/li><\/ul><\/figure>\n\n\n\n<p>For that, we place copepods, sampled from the mesocosms, in small respiration chambers. The chambers contain oxygen sensors that measure \u200b\u200bevery few seconds and thus we can obtain the respiration rates of the organisms. It seems simple, right? But not everything is what it seems, these chambers have a volume of 500 \u00b5l (visual measurement: 4 drops), and there cannot be any bubbles inside the chambers, otherwise the oxygen measurement is not correct. So, you have to put about two drops of the treatment water, remove the tiny small bubbles with a needle and place the copepods. Trust me when I tell you they swim fast. Once the organisms are inside the chambers, they have to be covered with a plastic lid, preventing the formation of bubbles and avoiding damaging the organisms.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"1024\" src=\"https:\/\/www.oceanblogs.org\/oceannets\/wp-content\/uploads\/sites\/78\/2022\/05\/picture-4.jpeg\" alt=\"\" class=\"wp-image-249\" \/><\/figure>\n\n\n\n<p>After 10 hours of experiments at 8 degrees, when you no longer notice the cold, you start thinking that jumping into the fjord is not such a bad idea.
