Table 2 shows the sightings reported to the International Ice Patrol in 

 1986, broken down by the source of the sighting and the size of iceberg 

 sighted. It is important to note that the IIP side-looking airborne radar 

 (SLAR) provided over 26% of the iceberg reports, the single largest 

 source of icebergs sightings. Given that IIP SLAR reconnaissance 

 usually takes place near the limit of all known ice, this sighting source 

 becomes especially important.
