1
Sea ice measurements and modelling of the Storfjorden polynya Lars H. Smedsrud, Ragnheid Skogseth, W. Paul Budgell, Frank Nilsen, Alastair D. Jenkins, and Bjørn Ådlandsvik
2
Biggs et al. 2000 Smedsrud and Skogseth (2006)
4
Frazil collection thickness & Wind speed Björk (2000) no length dependancy Alam & Curry 1998 Frazil forms > 4.5 m/s wind !!
5
Helicopter Electro Magnetic bird campaign, Storfjorden 2006 S. Hendricks and C. Haas (AWI) S. Gerland (NPI) L.H. Smedsrud (BCCR) F. Nilsen (UNIS) Flight track on May 2. 2006
6
(km) West East (Kapp Lee) South
7
Scottish Association for Marine Science (SAMS) Ice drifting buoys. Jeremy Wilkinson and Duncan Mercer (SAMS)
9
Budgell (2005) Boundary forcing and initialization from large scale Atlantic ROMS runs Sea ice concentration Sea surface temperature
10
Model ice thickness 'validation' - a polynya closing event
11
3 February 2000 Sea ice classification and polynya area detected by SAR Skogseth et al (2004) Mean ice thickness <0.3m = polynya ROMS model results Smedsrud et al (2006)
12
Wind forcing 0.3 N/m² equals 12-15 m/s NCEP forcing, Δx = 250 km Surface fluxes reflects NCEP ice cover [W/m²]
13
Storfjorden defined by Polynya area calculated inside the limited area Typical polynya width of 20 km February 2000 mean ice thickness [ m ]
