Abstract:
Vertical profiles were collected around Disko Bay in August 2024 focusing mainly on the upper 100 m of the water column which is affected by meltwater from Greenland. Samples were retained for macronutrients (nitrate, phosphate and dSi), DOC/DON, and carbonate chemistry (total alkalinity and pH). Bottle files from the CTD casts (SBE 911plus, Sea-Bird) are included with the measurements. Further details are available from the cruise report.
