Watching Ice Melt: Sea Level Rise Through Iceberg Calving

Researchers David and Denise Holland from New York University (NYU) and the Center for Sea Level Change at NYU Abu Dhabi, have filmed an enormous slab of ice breaking off the Jakobshavn glacier in Greenland and floating into the ocean.

Researchers David and Denise Holland from New York University (NYU) and the Center for Sea Level Change at NYU Abu Dhabi, have filmed an enormous slab of ice breaking off the Jakobshavn glacier in Greenland and floating into the ocean.

The fracturing event, known as calving, took 10 minutes and the researchers estimate the vertical slab was more than half a mile tall, more than twice the height of the Empire State Building.

NYUAD student Tiantian Zheng (NYUAD '18) was also with the researchers in Greenland to witness this powerful event.

The researchers employ remote sensing techniques, using both radar and seismic instruments, to collect data on calving events in order to better understand how melting glaciers contribute to rising sea levels. Researchers are hoping their observations and data set will provide insight into how and why calving occurs so that they can create new parameters to be used in climate models that include glaciers and their calving, ultimately leading to more robust projections of sea level rise.
