AbstractAn investigation into iceberg evolution is reported. The main focus of the work was a unique field observation program in which photographs were taken of two grounded near shore icebergs over a period of several days each. In addition to the photographic observations of the above water portion of the icebergs, underwater sound recordings were made periodically. Sound records include a large cracking event in which the iceberg calved. The results of the field program are presented, including some specific local wave erosion data. This is part of an ongoing effort to understand the physical processes involved in iceberg evolution. The work reported here was done under two separate contracts let to university based researchers: 391134 Iceberg Evolution Model - Wave Accelerated Erosion, and 391137 Iceberg Evolution Model 舑 Field Observations. Both contracts dealt primarily with gathering field data, the former concentrating on visual information and the latter on acoustic data, so a common field program was mounted and the results are documented jointly.
