to its iceberg deterioration model. 

 To further enhance the quality of 

 environmental data used in its 

 iceberg models, IIP also provided 

 weekly drifting buoy drift and sea 

 surface temperature (SST) 

 histories, and SLAR ocean feature 

 analyses to METOC and NEOC. 

 They used this information in their 

 water mass and SST analyses. 



No U. S. Coast Guard 

 cutters were deployed to act as 

 surface patrol vessels this year. 

 USCGC NORTHWIND was 

 deployed from June 3 to 27 to act 

 as a surface truth vessel for an 

 international SLAR evaluation 

 experiment, SLAREX '88. Two 

 U.S. Coast Guard and two Cana- 

 dian AES SLAR-equipped aircraft 

 participated in SLAREX '88. The 

 primary goal of the experiment 

 was to evaluate the ability of the 

 AN/APS-131 SLAR on the HU- 

 25B aircraft to detect icebergs. 

 The results of SLAREX '88 are 

 presented in Appendix E. 



The 1988 season marked 

 the 25th full year of IIP service for 

 the HC-1 30 'Hercules' aircraft. A 

 'Hercules' flew one ice reconnais- 

 sance patrol in 1963. The HC-1 30 

 assumed the Ice Patrol aerial 

 reconnaissance responsibilities for 

 the 1964 season until the present.
