The following report is an analyses of historic data contributed to an electronic database named the Program on Energy and Research and Development (PERD) Iceberg Sightings Database. This database is composed of iceberg sightings on the Grand Banks since the 1960s. It is known that there is historical documentation of iceberg sightings in this location as far back as the 1800s. The Institute for Ocean Technology (IOT) has started a project in an attempt to expand the PERD database by including all of this historical documentation. A time series such as this would show, during a time of suspected climate change, how the iceberg conditions of the present differ from those observed in the past. Several students have already made contributions to this project in the past, by recording the historical iceberg sightings into an electronic format, working backwards in time from the year 1960. My contribution to this project has been transcribing the iceberg sightings from the 1930s. Since the majority of my time has been spent on this task, I will attempt to show differences in the iceberg distribution of the 1930s decade and the distribution of icebergs observed in the most current decade of the 1990s.
