At noon in the sunshine, the rosette with two dozen Niskin bottles was lowered to a depth of more than 4000m. As the CTD descended, the primary focus of all involved was on which colour should represent which parameter. Pink for oxygen and blue for salinity? Or green for salinity and red for potential temperature? <\/p>\n<div id=\"attachment_35\" style=\"width: 306px\" class=\"wp-caption alignleft\"><a href=\"http:\/\/www.oceanblogs.org\/sonne-oasis\/wp-content\/uploads\/sites\/22\/2014\/07\/2014-07-10_002_SO234-2_KKrueger-UiO.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-35\" src=\"http:\/\/www.oceanblogs.org\/sonne-oasis\/wp-content\/uploads\/sites\/22\/2014\/07\/2014-07-10_002_SO234-2_KKrueger-UiO.jpg\" alt=\"Sorting the samples on deck.

An order of samples had been established, with insoluble gases taking priority, and nutrients and DNA bringing up the rear. Other analyses included CDOM, halocarbons, isoprene, pigments and DMS. Overall, the afternoon\u2019s investigations were successful, and we hope for much of the same tomorrow. Since we will be passing close to Madagascar, some of the participants are taking out their binoculars in the expectation of spotting some lemurs! <\/p>\n<p>(Dennis Booge and Robyn Granger, SO234-2 students)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The morning brought fair weather and calmer seas.
