6. HB1 HB2 HB3 E-W component at the Hornbanki section measured with a vessel mounted ADCP Mean from 2001-2005

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

9. 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.

23. CONCLUSIONS 1.The transport of AW within the NIIC is 0.85 Sv and the associated heat transport is 23 TW 2.This is 11% and 8% of the total transport and heat transport to the Nordic Seas respectively 3.A seasonal variation in the transport with an amplitude of 0.27 Sv is observed with a minimum in February/March and a maximum in late spring and summer 4.There is considerable interannual variability in the flow 5.The flow during 1994-1995 was 60% of the flow in 1994-2008 6.In 2003 the flow was 32% more than the flow in 1994- 2008
