Archived IIP Iceberg Observations 



IIP has been observing icebergs in the western North Atlantic Ocean since it began regular 

 patrols in 1913. Throughout its early history Ice Patrol documented iceberg sightings in its yearly 

 bulletins. In 1993, Anderson used original paper records of iceberg reports from 1960-1982 to 

 create a digital record of all iceberg sightings for the period. Each year after 1982 IIP has 

 produced a digital record of all iceberg-sighting reports. Anderson's original file and each yearly 

 record are sent to the National Snow and Ice Data Center (NSIDC). NSIDC is part of the 

 University of Colorado Cooperative Institute for Research in Environmental Sciences, and is 

 affiliated with the National Oceanic and Atmospheric Administration National Geophysical Data 

 Center through a cooperative agreement. NSIDC makes HP's iceberg sighting data available 

 online at http://nsidc.org/data/g00807.html (NSIDC, 1995). 



The iceberg data provided by IIP constitute a major part of the comprehensive iceberg- 

 sighting database described by Verbit et al. (2006), which is sponsored by the Canadian Program 

 of Energy Research and Development (PERD). The PERD iceberg-sighting database also 

 includes observations from the oil industry drilling sites, various field surveys, etc. All the data 

 are subjected to a rigorous data-verification process before being placed the database. It is 

 available on line at:
