Introduction
The included auxiliary figures assist in the comparison of the presented findings to
previously published circulation and transport results for the region. In particular, the
supplemental figures clearly indicate the seasonal distribution of data collection, as well
as the average hydrography used to determine the lower integration depth for Atlantic
Water transport. Detailed annual velocity profiles also indicate the interannual variability
over the Iceland Faroes Ridge section.
1. fs01.png (Figure S1) Number of sections collected along each transect during
each season.
2. fs02.png (Figure S2) Collection location for all ICES hydrographic data used for
the calculation of AW depth. Lines represent the mean path of each Norröna
transect, x’s are individual temperature and salinity observation locations, and
contours show bathymetry for every 200 m from 100-1500 m depth.
3. fs03.eps (Figure S3) Mean temperature, salinity, and potential density from all
available hydrographic data within 50 km of the FSC Middle Route. Observations
were first averaged into 25 km lateral by 20 m vertical bins, and then averaged
over time to produce contours. Grey lines show the observation locations used for
the interpolation along each transect. Black dotted lines show AW depth reference
levels (5°C, 35.05 PSU, and σt=27.8) for each parameter.
4. fs04.eps (Figure S4) Mean temperature, salinity, and potential density from all
available hydrographic data within 50 km of the FSC Southern Route.
Observations were first averaged into 25 km lateral by 20 m vertical bins, and
then averaged over time to produce contours. Grey lines show the observation
locations used for the interpolation along each transect. Black dotted lines show
AW depth reference levels (5°C, 35.05 PSU, and σt=27.8) for each parameter.
5. fs05.eps (Figure S5) Mean temperature, salinity, and potential density from all
available hydrographic data within 50 km of the IFR Route. Observations were
first averaged into 25 km lateral by 20 m vertical bins, and then averaged over
time to produce contours. Grey lines show the observation locations used for the
interpolation along each transect.

Southern sections (note the Southern section has been shifted by 30 km toward
the east for clearer alignment of the SSC with the Middle route).
