Current* Antarctic large iceberg positions derived from QuikSCAT**

* Last revised: 17:05:23 07/02/09

**Operational users please note: This list cannot possibly contain all potentially hazardous icebergs in Antarctic waters -- QuikSCAT was designed for measuring ocean winds, not icebergs. QuikSCAT's serrindipitous utility for iceberg tracking has proven useful, but is not perfect: Smaller bergs (less than 5 km) cannot be reliably tracked and loss of contrast due to surface melting can result in loss of track for larger icebergs. Futher, as the SCP team is not an operational agency, errors are expected and we cannot be held responsible for omissions or errors in this database. Also note that the large icebergs tracked here tend to shed smaller iceberg fragments which are serious navigation hazards in nearby areas. Fragments (large and small) can drift substantial distances from their origins.

This information supplements the Antarctic Iceberg Webpage maintained by the U.S. National Ice Center (NIC). If an inconsistency is observed, we recommend that NIC be considered authoritative.

This page is typically updated once or twice a week, typically on Mondays and Fridays. Positions reported here are extracted from near real-time QuikSCAT data. Positions reported in the full iceberg database are generated from science data and have been more accurately tracked. The full database is updated only a few times per year
