Summary

Description
English: Iceberg A23a, currently the largest iceberg on Earth, was captured floating off the tip of the Antarctic Peninsula on February 14, 2024, by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite.

Compared to the image published as the MODIS Image of the Day on November 28, 2023, (available here) the iceberg appears to have been nearly stationary since that time. But that impression is misleading—in fact, A23a has been spinning in the currents off the Antarctic Peninsula for the last several months. And the slow-motion ballerina-worthy spin was captured by MODIS imagery.

The British Antarctic Survey collated a set of MODIS images of the iceberg acquired between December 20, 2023, and February 6, 2024, and set them in motion. The clip, published on the Survey’s X account, shows the massive iceberg completing a full 360-degree spin, plus a bit extra, during that time.

Because icebergs move only by drifting on ocean currents, it is not rare for them to be caught in eddies or circular currents as they move northward into warmer waters. Once the northward drift carries A23a to the Southern Ocean, it is expected to begin to melt more rapidly.
