Scientists reported on Monday that a large glacier in the northwest Greenland interacts with ocean tides, resulting in previously incomprehensible melting and potentially faster sea level rise . A group of glaciologists from the University of California, Irvine and NASA's Jet Propulsion Laboratory published the study on Monday in the journal Proceedings of the National Academy of Sciences. Observations from the Petermann Glacier revealed that the glacier's grounding line—the area where the ice sheet begins to extend over the ocean—can shift significantly as the tide approaches each day.According to Enrico Ciracì, lead author of the study and a UCI scientist, the Petermann Grounding Line line “migrates between 2 and 6 kilometers (1.2 to 3.7 mi) s ebb and flow. This is an important finding: The traditional view among scientists was that the grounding line did not migrate with the tides—and that represents another major source of melting that could accelerate sea-level rise. Between 2016 and 2022, warmer tidal cycles melted a 670-foot hole in the bottom of the glacier along the grounding line — big enough to fit two Statues of Liberty inside. This phenomenon could worsen in the coming years and decades as ocean temperatures rise. CNN recently she announced , that sea surface temperatures were the highest on record this spring — a spike that has alarmed scientists, who fear it could be a factor.
