Fig. 23 in Taxonomy and distribution of recent species of the subfamily Nodosariinae (Foraminifera) in Icelandic waters
Fig. 23. Simplified scheme of the main sea currents that affect bottom water temperature in the vicinity of Iceland. Surface currents affecting the continental shelf and slopes are symbolized as dotted lines: the cold East Icelandic Current (EIC) and the cold East Greenland Current (EGC), jointly form the Polar Front north off Iceland; the warmer Irminger Current (IC), is a branch of the North Atlantic Current (NAC). Unbroken blue lines, affecting deeper bottom waters (> 500 m): the Cold Overflow Bottom Water currents (COBW), the North Icelandic Jet (NIJ) and the Icelandic-Faroe Slope Jet (IFSJ) (compiled after Valdimarsson et al. 2012; Logemann et al. 2013; Jochumsen et al. 2017; Semper et al. 2019; Símonarson et al. 2021).
