Profiles obtained from Maria S. Merian cruise MSM130 ('Polar Beast') July-August 2024 across the southeast Greenland shelf and in three fjord systems. Water samples were obtained from the ship's CTD rosette system and are matched to calibrated bottle data from the CTD casts. Further sample and analysis details are available in the cruise report. Macronutrient samples were frozen after collection, returned to the home laboratory and analyzed using an autoanalyzer after defrosting overnight. Amorphous Si samples were collected on filters, frozen after collection, returned to the home laboratory and analyzed using an alkaline leach.
