Anna Olivé Abelló wrote an article stating for IGE website: Antarctic icebergs are huge ice blocks that break off from glaciers and floating ice shelves and drift through the Southern Ocean. As these icebergs melt and release freshwater, they modify the global ocean circulation and therefore the global climate.
Icebergs also transport sediments and nutrients that fertilise the Southern Ocean, support phytoplankton growth, and indirectly help remove carbon dioxide locally from the atmosphere, playing thus an essential role in Earth’s climate. Because of these multiple roles, icebergs need to be represented in numerical climate models to accurately simulate the ocean evolution and environmental conditions in a changing climate.
