ALT #COP29: Join in-person or online! ‘Polar Oceans: the Triple Threat of Acidification, Warming and Freshening’ ❄️ The Arctic and Southern Oceans are crucial components of the Earth system. Their unique ecosystems are under serious threat from warming, acidification, freshening and ice loss. Polar oceans are already experiencing changes in chemistry, and continued warming is leading to range shifts, changes in food webs, ecosystems, fisheries, and climate regulation. This session highlights the latest scientific and discusses the wider societal and political impacts, while emphasizing the need to raise ambition for reducing emissions.

ALT Working with recycled polymer and sourced fabrics 2nd year costumes students realised the "Coccolithophore" costume design by Jacqueline Ball. Students began by taking personal measures and drafting an overall shape of the "dress". It was decided that 3D printing the chalky coccolithophore shapes would give a more accurate representation of these organisms and so a printable model was found. The costume foundation was made up from a base shape with steel bands inserted to support the 3D printed forms. Layers of blue and white tulle and organza folded puffs were used to create a foundation layer to create a textured surface and each 3D printed shape were sewn on by hand, a total of 100 shapes were individually placed and sewn to create the chalky effect. Care was taken so that there was freedom of movement and that the costume was easy to put on. In total the costume took 6 days to make!
