Current* Antarctic large iceberg positions derived from ASCAT**

* Last revised: 18:12:00 05/20/15

**Operational users please note: This list cannot possibly contain all potentially hazardous icebergs in Antarctic waters -- Scatterometers such as ASCAT were designed for measuring ocean winds, not icebergs. Scatterometer data is useful for tracking icebergs, but is limited. During the Austral summer contrast between ocean and melting icebergs is reduced, which can result in gaps in visibility. 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 dataset 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 possibly Fridays. Positions reported here are extracted from near real-time ASCAT 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
