7. Ice Shelf Rift Time-Lapse Photography, Antarctica [NSIDC-0351]
From November 2004 to March 2005, on the Ross Ice Shelf, Antarctica, an automated "web cam" was operated on the southward facing lip of a large ice-shelf rift to produce a photographic record of processes ...


8. Iceberg Capsize Kinematics and Energetics [MacAyeal_Iceberg_capsize]
To investigate the physics of iceberg capsize, a laboratory-scale experimental apparatus was created to simulate iceberg calving and capsize (and other phenomena) at a 1/100,000 scale. The data set ...


9. Iceberg Capsize Kinematics and Energetics [NSIDC-0590]
This data set represents a typical single iceberg capsize experiment. Included in this data set are all the parameters of the plastic iceberg's density and dimensions, the density of the water surrounding ...


10. Iceberg Firn Temperatures, Antarctica [NSIDC-0352]
Since November of 2005, 12 thermistors were planted in the upper 2.5 meters of the firn on iceberg C16, Antarctica. Temperature data are collected every 20 minutes and are transmitted via ARGOS satellite ...


11. Iceberg Harmonic Tremor, Seismometer Data, Antarctica [NSIDC-0349]
Seismometers were placed on a 25 km by 50 km iceberg called C16 in the Ross Sea, Antarctica, to identify the Iceberg harmonic Tremor (IHT) source mechanism and to understand the relevance of IHT to ...


12. Iceberg Harmonic Tremor, seismometer data [MacAyealseismo_tremor_0229546]
Iceberg harmonic tremor (IHT) emanating from tabular icebergs in the Southern Ocean and around the coast of Antarctica is observed as seismoacoustic signals on islands in the equatorial Pacific, as ...


13. Iceberg Tiltmeter Measurements, Antarctica [NSIDC-0353]
Time series of tiltmeter observations (tilt about two horizontal axes in microradians) for a 34 day period on iceberg C16 while it was aground near Ross Island in late 2001 to early 2002. Data shows ...

Time series of tiltmeter observations (tilt about two horizontal axes in microradians) for a 34 day period on iceberg C16 while it was aground near Ross Island in late 2001 to early 2002. Data shows ...


15. Larsen B Ice Shelf supraglacial lake depths [Larsen_B_Ice_Shelf_supraglacial_lake_depths_February_2002]   PARENT METADATA
This data represents a snapshot of supraglacial lake depths, areas and x,y location on the Larsen B Ice Shelf in February, 2000. The data was derived from processing a multi-spectral Landsat 7 image ...


16. Larsen B Ice Shelf supraglacial lakes (depth, area, 2000) [MacAyeal_0944248]
In this data, we provide an estimate of surface water depth for the surface of the Larsen B Ice Shelf on February 21, 2000, using a Landsat 7 multi-spectral image composite. The surface water depth ...
