Iceberg

NAME

Iceberg - Copernicus Sea Ice Berg satellite observations

DESCRIPTION

This product fetches observation data from the SAR Sea Ice Berg Concentration and Individual Icebergs Observed with Sentinel-1 & RCM dataset, covering the Arctic ocean plus parts of the northwestern Atlantic as shown.

This product is intended for a university course and can be terminated without notice after June 2026. Data files are currently updated manually, so the latest files may take some days to show up. Currently data from Jan 2023 are available.

DATA FORMAT

Data are delivered in GeoJSON, containing observations for weekly intervals.

BRGARE

The area of the iceberg (square meters). I.e. the summed area of the pixels making up the iceberg

IA_BLN

Maximum horizontal iceberg length (meters) at the waterline level – this distance is derived as the maximum distance (edge to edge) in the polygon circumferencing the pixel-cluster that makes up the iceberg in the SAR imagery

IA_BCN

Local iceberg concentration based on distance to nearest iceberg in nautical miles (nm). Distance categories in SIGRID3 code format:

    10: >45 nm between icebergs
    20: 15 - 44 nm between icebergs
    30: 10 - 14 nm between icebergs
    40: 7 - 10 nm between icebergs
    50: 5 - 6 nm between icebergs
    60: 3 - 4 nm between icebergs
    70: 1 - 2 nm between icebergs
    80: 0.5 - 1.0 nm between icebergs
    90: <0.5 nm between icebergs
    99: Undetermined/Unknown
ais_chk

Shows whether the observation is checked for being located in the neighborhood of a registered ship-track. If the target is on/close to a track, then it is most likely a ship rather than an iceberg. If AIS data were available for the applied satellite scene this field will be assigned the distance to the nearest ship in km, otherwise it will get the value “NA”.

For more details, see the dataset documentation.

USAGE

Parameters

date (optional)

Fetch data for the weekly interval ending with date of format "YYYY-MM-DD". If not specified, use the latest data for the current month.

period (optional)

Used only with /available. List all data files for the month given in period of format "YYYY-MM". Defaults to all months since Jan 2023.
