#gullarray contains
#note: numbers are colums, for index do -1
#local gull information:
0 : index (should be 0, 1, 2, 3 ... since it was sorted before)
1 : tag of the gull (should be sorted somehow)
2 : lat
3 : lon
4 : ic at gull position (directly)
5 : ic at gull position (~10km radius average)
6 : ic-std at gull position (~10km radius)
7 : ic at gull position (~50km radius average)
8 : ic-std at gull position (~50km radius)
9  : distance to ice_edge (in km, approximately +/-3km)
10 : distance to coast (in km, approximately +/-3km)
11 : area of open water i.e. ic 0 (within 50km radius)
12 : area of ic 1-10 (within 50km radius)
13 : area of ic 10-20 (within 50km radius)
14 : area of ic 20-30 (within 50km radius)
15 : area of ic 30-40 (within 50km radius)
16 : area of ic 40-50 (within 50km radius)
17 : area of ic 50-60 (within 50km radius)
18 : area of ic 60-70 (within 50km radius)
19 : area of ic 70-80 (within 50km radius)
20 : area of ic 80-90 (within 50km radius)
21 : area of ic 90-100 (within 50km radius)
22 : area of ic nan (within 50km radius)
#information on the areas on that exact day
23 : time (ordinal, days since 1.1.1, integer value, no exact time)
