ObjectivesCruise 64PE358 occupied a total of 14 stations. The first was a test station to 100 m depth to check the sensors of the ultraclean CTD (UCC). The second station was the LOCO2 mooring site at 59°12.35'N and 39°30.53'W. Here a mooring belonging to the Physical Oceanography department at NIOZ was serviced (project: THOR, PI: Laura de Steur). To investigate the physical oceanographic setting before and after servicing of the mooring at LOCO2 two casts (cast 3 & 5) were executed with the UCC. Stations 3-7 were executed to complete the western North Atlantic GEOTRACES transect as sampled during Netherlands GEOTRACES leg 1 (64PE319). During 64PE319, storms made it impossible to sample these stations. A full depth and a shallow cast were performed at each of the stations 3-7. The deep casts were executed as part of GEOTRACES and the shallow casts were executed as part of a GEOTRACES process study to investigate the internal cycling of Fe, Co, Zn and Cd in the upper 300 m of the water column. Their distribution was determined with respect to their dissolved, colloidal and truly soluble fraction as well as their organic complexation (Fe and Co) in relation to phytoplankton abundance and the physical oceanography in the upper 280 m of the water column. Seven extra shallow stations were performed on transect back to Texel. These shallow stations extended the dataset for the fine distribution of Fe, Co, Zn and Cd, extended the dataset that investigates the photo-acclimation of phytoplankton and investigated the CO2 system along the Warm Gulf Stream and beyond.
