Positions and dimensions of the A68 icebergs between September 2020 and April 2021

This dataset contains daily positions of the A68 family of giant icebergs during their drift through the Scotia Sea and South Atlantic between 2020-09-01 and 2021-04-16. Positions were obtained using optical imagery collected by MODIS Aqua and Terra satellites. For the parent iceberg A68A, the evolving dimensions (long and short axis length, area) are also provided, based on Synthetic Aperture Radar imagery acquired by Copernicus Sentinel 1A and 1B satellites. This data can be used to plot the trajectories of the A68 icebergs during their drift in the Scotia Sea and near South Georgia. This data was collected during an MSc/MRes student project at the Department of Geography, University of Sheffield, in 2020/21. The work was not supported by any funding or research grants.
