Current* Antarctic large iceberg positions derived from ASCAT**
* Last revised: 14:34:00 12/06/16
**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

designations are used where possible. Additional fragments are
numbered. Icebergs not designated by NIC are denoted as "uk".
Fragments not separately tracked by NIC may have additional
numbers following their designation.
