1 The Challenger Mission Leg 1: Reykjavik, Iceland to The Azores
Jess Castoro, Chris Puskas, Eva Pena, Holly Broadus & Nilsen Strandskov

2 Materials: The CTD (Conductivity, Temperature & Depth) mounted on the Slocum Glider has taken measurements of temperature on every downcast along the track from Iceland to the position on October 5th Argo Drifter positioned off of Iceland close to June 23rd and near Silbo’s position on October 5th

3 Temperature Salinity Are the temperature and salinity changes regional or temporal?

4 Temperature Collected by Silbo
Surface ~10˚ C 1000m ~ 5˚ C to Surface ~18˚C 1000m 8˚C

5 Temperature Comparison from the First Week:
Argos Drifter off of Iceland Argos Drifter at Silbo’s Location in October meters meters 10˚C-6˚C vs 16˚C-7˚C ˚C ˚C

6 Temperature Comparison for the week of October 3rd
Argos Drifter off of Iceland Argos Drifter at Silbo’s Location in October meters meters 11˚C- 6˚C vs 19˚C-7˚C ˚C ˚C

7 Silbo saw a change from the surface being ~10˚C and at depth being 5˚C by Iceland to a range of 18˚C to ~7˚C at his position on October 3rd The Argos drifter off of Iceland measured a depth range from ˚C in July to at the end of October The Argos drifter near Silbo’s position in October measured ˚C at the end of June compared to ˚C July 2 Oct 3

8 Salinity Collected by Silbo

9 Salinity Comparison from the First Week:
Argos Drifter at Silbo’s Location in October Argos Drifter off of Iceland meters meters psu psu

10 Salinity Comparison from the Week of October 3rd :
Argos Drifter off of Iceland Argos Drifter at Silbo’s Location in October meters meters psu psu

12 In Conclusion: Temperature:
The temperature up near Iceland changed very little over the time we analyzed, while the temperature for the position near October 3rd underwent a much larger change. It seems the temperature difference may have been both regional and temporal. Salinity: Concentration differences seem to be regional and potentially due to peak fresh water flux from height of ice melt and the outer reaches of the Mediterranean Outflow.
