A massive iceberg calved from Greenland’s Petermann Glacier in 2026, drifted from its fjord into Nares Strait, briefly rammed Joe Island, and then continued to drift with limited fragmentation, highlighting ongoing Arctic ice dynamics and potential hazards from drifting ice.
New satellite images show a 29-square-mile ice island calved from Greenland’s Petermann Glacier after fractures propagated over months; ESA’s Sentinel-1/2 tracked the rapid breakup, highlighting the glacier's fragility and signaling more calving events as researchers continue monitoring.
ESA satellite imagery shows a 29-square-mile section of Petermann Glacier’s floating ice tongue broke away on Aug. 4, 2026, forming a Manhattan-sized iceberg up to 492 feet thick—the largest floating-ice loss at the glacier since 2012. The event signals ongoing Arctic ice change linked to warming, with potential further detachments and implications for glacier dynamics, sea-level rise, and shipping routes as researchers monitor the evolving calving and its wider ocean effects.
Sentinel-1 radar imagery captured a 76 sq km section of Petermann Glacier’s floating ice tongue detaching on 4 August 2026, forming a Manhattan-sized ice island up to 150 metres thick—the Arctic’s largest calving event since 2020. The researchers warn two additional large detachments (≈97 and 87 sq km) could follow as fractures propagate. The one-day repeat radar data enabled near‑real‑time monitoring, underscoring the value of Copernicus Sentinel-1 for tracking glacier dynamics and potential impacts on shipping and the Arctic environment.
A massive iceberg broke off Greenland’s Petermann Glacier, forming an ice island up to 492 feet thick and about 29.5 square miles (76.4 sq km) in surface area—roughly the size of Manhattan—marking the glacier’s largest loss of floating ice since 2012, with two more calving events anticipated as scientists monitor the drifting ice islands and assess risks to ships and offshore infrastructure.
