Explanation:

An iceberg is ice that broke off from glaciers or shelf ice and is floating in open water.

• Iceberg A68a, which calved from Antarctica in 2017, has been floating off the coast of South Georgia island.
• The British Antarctic Survey (BAS) will launch a research mission to study A68a’s impact on the ecosystem.
• BAS is a component of the Natural Environment Research Council (NERC). (UK Research and Innovation) which delivers and enables world-leading interdisciplinary research in the Polar Regions.
• Icebergs travel with ocean currents and either get caught up in shallow waters or ground themselves.
• The Antarctic Circumpolar Current (ACC) is the most important current in the Southern Ocean, and the only current that flows completely around the globe. 
• The US National Ice Center (USNIC) is the only organisation that names and tracks Antarctic Icebergs.

Hence both statements are correct.
