Figure 2
Salinity and nutrient distributions at 10–11 m depths in the Fram Strait region. (a) Salinity, (b) fixed N, (c) Si, (d) dFe, (e) Fe(N)* nutrient deficiency, and (f) fluorescence. Primary (g) and secondary (h) nutrient deficiency after Moore35: Fixed N (purple), dFe (red) and Si (green). Black dots indicate the sampling locations (all 10 m depth). Black arrows indicate sites of bioassay experiments (excl. E4). The location of Nioghalvfjerdsbrae (79NG) and Zachariæ Isstrøm (ZI) are depicted in ‘a’. Isohalines (contours, 11 m) distinguish the Polar Surface Water (S < 31.4, bold) of the southward-directed East Greenland Current (EGC, S < 34.8, < 0°E) from Intermediate Water (34.8–35.1) and Atlantic Water (S > 35.1, thin black) of the northward-flowing West Spitsbergen Current (WSC). Figure made using Ocean Data View software based on DIVA gridding calculations (Schlitzer, R., Ocean Data View, version 5.2.1, https://odv.awi.de, 2020).
