We will remain on the Louis until Thursday morning to wrap up any remaining work, which includes processing samples, organizing and quality-controlling data, writing science reports, packing lab equipment\/personal gear, and much more. Members of the science team split up to divide and conquer the long list of tasks. For example, C\u00e9line Gu\u00e9guen and Magali Pucet spent the morning processing their last fluorescent dissolved organic matter (FDOM) samples and packing their lab equipment. Meanwhile, Erinn Raftery reviewed the salinity, chlorophyll, ammonium, and dissolved oxygen sample data that were processed on board. The Niskin bottle data and CTD profiles will be organized and published in a few months, after they have been fully calibrated and quality-controlled.<\/p>\n<p>We reunited at 11 am for the daily science meeting, where Dominique Baker explained how microbial communities in the Beaufort Gyre have been adapting in response to global climate change. It&#8217;s currently unclear how these changes will affect higher trophic levels and carbon fixation (the conversion of atmospheric carbon to organic compounds) in the ocean. Dominique has been collecting samples on this year&#8217;s cruise to track the compositions and activity of these microbial communities and identify potential environmental drivers for observed changes.<\/p>\n<p>Our final few days on board have also been filled with lots of celebration of the hard work put in by the science team and ship&#8217;s crew over the last 5 weeks. For regular readers of the dispatch, it may come as no surprise that one of many ways we celebrate on the Louis is through dessert. From special birthday cakes to Sunday sundaes, we have certainly enjoyed our fair share of celebratory sweet treats on board. A huge thanks Assistant Cook Carter Guy who prepares 4-5 wonderful desserts for us to enjoy every day! Only 1 day left for us to indulge in these decadent treats!<\/p>\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/beaufortgyre\/wp-content\/uploads\/sites\/108\/2025\/10\/Picture1-5.png\" alt=\"Figure 1: The most recent sea ice concentration map for the Beaufort and Chukchi Seas (Source: https:\/\/data.seaice.uni-bremen.de\/databrowser\/). \" height=\"452\" width=\"624\" title=\"Picture1\" \/>\n\t\tFigure 1: The most recent sea ice concentration map for the Beaufort and Chukchi Seas (Source: https:\/\/data.seaice.uni-bremen.de\/databrowser\/). \n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/beaufortgyre\/wp-content\/uploads\/sites\/108\/2025\/10\/Picture2-5.png\" alt=\"Figure 2: Map showing our current location en route to Cambridge Bay. \" height=\"801\" width=\"1430\" title=\"Picture2\" \/>\n\t\tFigure 2: Map showing our current location en route to Cambridge Bay. \n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/beaufortgyre\/wp-content\/uploads\/sites\/108\/2025\/10\/Picture3-3.jpg\" alt=\"Photo 1: Dominique Baker giving a presentation during the daily science meeting. \" height=\"468\" width=\"624\" title=\"Picture3\" \/>\n\t\tPhoto 1: Dominique Baker giving a presentation during the daily science meeting. \n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/beaufortgyre\/wp-content\/uploads\/sites\/108\/2025\/10\/Picture4-4.jpg\" alt=\"Photo 2: Magali Pucet processing samples of fluorescent dissolved organic matter (FDOM). \" height=\"468\" width=\"624\" title=\"Picture4\" \/>\n\t\tPhoto 2: Magali Pucet processing samples of fluorescent dissolved organic matter (FDOM). \n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/beaufortgyre\/wp-content\/uploads\/sites\/108\/2025\/10\/Picture5.png\" alt=\"Photo 3: Some of the desserts served on the Louis.
