The characteristics and seasonality of the Svalbard branch of the Atlantic Water (AW) boundary current in the Eurasian Basin are investigated using data from a six‐mooring array deployed near 30°E between September 2012 and September 2013. The instrument coverage extended to 1,200‐m depth and approximately 50 km offshore of the shelf break, which laterally bracketed the flow. Averaged over the year, the transport of the current over this depth range was 3.96 ± 0.32 Sv (1 Sv = 10^6 m^3/s). The transport within the AW layer was 2.08 ± 0.24 Sv. The current was typically subsurface intensified, and its dominant variability was associated with pulsing rather than meandering. From late summer to early winter the AW was warmest and saltiest, and its eastward transport was strongest (2.44 ± 0.12 Sv), while from midspring to midsummer the AW was coldest and freshest and its transport was weakest (1.10 ± 0.06 Sv). Deep mixed layers developed through the winter, extending to 400‐ to 500‐m depth in early spring until ... : Gear 1: CTD-R SBE37, SN 1237; Gear 2: CTD-R SBE37, SN 9487; Gear 3: CTD-R SBE37, SN 230; Gear 4: RCM9/11, SN 461; Gear 5: RCM7/8, SN 9770; Gear 6: RCM9/11, SN 506; Gear 7: RCM9/11, SN 504; Gear 8: RDI-ADCP, SN 1408601; Gear 9: RDI-ADCP, SN 1408602; Gear 10: RDI-ADCP, SN 1408603; Gear 11: RDI-ADCP, SN 1408604; Gear 12: RDI-ADCP, SN 1408605; Gear 13: RDI-ADCP, SN 1408606; Gear 14: RDI-ADCP, SN 1408607; Gear 15: RDI-ADCP, SN 1408608; Gear 16: RDI-ADCP, SN 1408609; Gear 17: RDI-ADCP, SN 1408610; Gear 18: RDI-ADCP, SN 1408611; Gear 19: RDI-ADCP, SN 1408612; Gear 20: RDI-ADCP, SN 1408613; Gear 21: RDI-ADCP, SN 1408614; Gear 22: RDI-ADCP, SN 1408615; Gear 23: RDI-ADCP, SN 1408616; Gear 24: RDI-ADCP, SN 1408617; Gear 25: RDI-ADCP, SN 1408618; Gear 26: RDI-ADCP, SN 1408619; Gear 27: RDI-ADCP, SN 1408620; Gear 28: RDI-ADCP, SN 1408621; Gear 29: RDI-ADCP, SN 1408622; Gear 30: RDI-ADCP, SN 1408623; Gear 31: RDI-ADCP, SN 1408624; Gear 32: RDI-ADCP, SN 1408625; Gear 33: RDI-ADCP, SN 1408626; Gear 34: RDI-ADCP, SN 1408627; ...
