1 984 have indicated that the 

 FNOC velocities are consistently 

 too large. This was an added 

 error source in computing 

 geostrophic current motion using 

 the existing method. By using a 

 50m tether and eliminating the 

 step of removing the wind driven 

 current, the new TOD motion 

 should more closely measure the 

 geostrophic current in our 

 operating area. 



1 1 P intends to continue using 

 TODs to modify the historical 

 current field on a real-time basis. 

 The experiment of a TOD 

 following the geostrophic current 

 will be repeated on future 

 hydrographic cruises using a CTD 

 system rather than Nansen 

 bottles to measure the water 

 column characteristics. 

 The results from the iceberg 

 deterioration study are very 

 encouraging, but our data set of 

 one is not large enough to draw 

 any conclusions. The 

 deterioration model will be used 

 in its present form, and a total 

 deterioration percentage of 

 1 75% of the original length will be 

 used as the point where deletion 

 from the active iceberg list will be 

 considered. 



IIP does not plan to make further 

 changes to our iceberg drift 

 model before next season. IIP 

 plans to evaluate the drift model 

 using the drift data obtained from 

 HORNBEAM, datafromTIROS 

 Arctic Drifters aboard icebergs 

 during the 1983 season, and 

 other sources. This analysis 

 should allow IIP to evaluate the 

 estimates of the model's error.
