definition of trends. Resurvey of certain glaciers 

 could better establish these trends. Objective 2, 

 completed for Jacobshavn Glacier, can also be 

 accomplished for the other major producers by 

 resurvey where the time spent at each glacier is 

 basically devoted to measurements of glacier 

 movement. Thus, future plans for the West 

 Greenland Glacier .Survey call for continuing the 

 resurvey program of the major iceberg producing 

 glaciers to obtain verification data and to detect 

 the continuance of the recession trends. Site 

 reoccupation would include both tidal flexure 

 measurements and short-term flow velocity de- 

 terminations. These data will allow iceberg pro- 

 duction calculations. A total of three more 

 survey expeditions, visiting only the most pro- 

 ductive glaciers, would be required. In addition, 

 a program of ERTS Satellite monitoring of the 



glaciers will be commenced. As satellite tech- 

 nology improves, all iceberg production and 

 glacier retreat monitoring will be accomplished 

 remotely and at comparatively little expense. 



The quantity of photographs and recorded 

 data obtained since 1968 is large. The Glacier 

 Survey has very thorough documentation of the 

 glaciers of West Greenland. This information 

 would be quite useful as a reference resource to 

 glaciologists, oceanographers, climatologists and 

 geographers. Historically, these data are an im- 

 portant benchmark in the geophysical studies of 

 the earth. I hope they will be published and 

 made available in the most complete and defini- 

 tive form possible, with a complete narrative, 

 data measurements, calculations and color photo- 

 graphs, with the photographs being of prime 

 importance.
