Table 2 shows monthly 

 estimates of the total number of 

 icebergs that crossed 48°N for 

 the pre-lnternational Ice 

 Patrol era, and for the ship, 

 aircraft visual, and aircraft 

 SLAR reconnaissance eras. 

 Table 3 compares the estimated 

 number of icebergs crossing 

 48°N for each month of 1987 

 with the monthly mean number 

 of icebergs crossing 48°N for 

 each of the four different eras. 



During the 1987 ice 

 year, an estimated 318 ice- 

 bergs drifted south of 48°N 

 latitude, compared to 204 

 icebergs drifting south of 48°N 

 during 1986. The number of 

 icebergs crossing 48°N during 

 1987 was less than the SLAR 

 reconnaissance era average. It 

 is important to note, however, 

 that this average is based on 

 only four years of data. The 

 average number of icebergs 

 drifting south of 48°N from 

 1913 to 1987 is 395 icebergs 

 (Appendix B). With 318 

 icebergs drifting south of 48°N, 

 1987 was deemed an interme- 

 diate or average ice year (Ap- 

 pendix B). 



April 15, 1987, 

 marked the 75"" anniversary of 

 the sinking of the RMS TITANIC. 

 A memorial wreath was placed 

 near the site of the sinking 

 during an ice reconnaissance 

 patrol to commemorate the 

 nearly 1500 lives lost. 



Table 2. Total Icebergs South of 48^ N - The four periods shown are pre- 

 lnternational Ice Patrol (1900-1912), ship reconnaissance (1913-1945), aircraft 

 visual reconnaissance (1946-1982), and SLAR reconnaissance (1983-1986).
