  1. Flow of Atlantic water to the North Icelandic shelf Steingrímur Jónsson1,2and Héðinn Valdimarsson1 1Marine Research Institute and 2University of Akureyri

  2. KG6 LB6 10 cm/s Map of the area. The red dots denote current meter positions and the blue denote CTD stations. Depth contours are 100, 200, 500 and 1000 meters.

  3. Salinity on the Hornbanki section. Also shown is the position of the current meters as yellow dots.

  4. Timeline for themeasurements

  5. Hornbanki Hornbanki

  6. HB1 HB2 HB3 E-W component at the Hornbanki section measuredwith a vesselmounted ADCP Meanfrom 2001-2005

  7. Salinity on the Hornbanki section. Also shown is the position of the current meters as yellow dots.

  8. Time series of temperature from the current meters. Also shown is the average of the E-W component of the velocity at mooring H3 at 84m depth (black line). Each tick on the x-axis denotes the beginning of the corresponding month. The yellow lines indicate the times when CTD sections were taken. Data are weekly running averages.

  9. Potential temperature across the Denmark Strait at the sill, Sep. 1997.
