According to a statement released by the University of Tasmania Australia (UTAS) on Monday (7/9), an international team of scientists studying Antarctica is part of a coordinated plan to conduct geophysical surveys across the continent’s entire coastal region to improve future sea-level rise predictions. The initiative, named “RINGS around Antarctica,” involves three planned survey series looping the continent to track land-based ice flow, grounding zones where land glaciers transition to floating ice shelves, and ocean-facing ice shelves to identify critical processes driving ice loss.
Global Science Collaboration Targets Coastal Antarctica
The research, published in the American Geophysical Union’s journal Reviews of Geophysics, summarizes current understanding of how ice, oceans, the atmosphere, and the solid Earth interact in Antarctica’s coastal zones while highlighting major knowledge gaps and the need for pan-Antarctic observations.
“This ambitious and globally coordinated campaign will address the largest uncertainties in predicting Antarctic sea-level rise, which has major implications for coastal planning and efforts to support low-lying nations, including Australia’s neighbors in the Pacific region,” said Felicity McCormack, one of the study’s lead authors from Securing Antarctica’s Environmental Future at Monash University in Australia, as cited by UTAS.
Tracking Ice Loss and Global Coastline Changes
According to UTAS statements, another co-author, Zhao Chen from the UTAS Institute for Marine and Antarctic Studies (IMAS), stated that the plan could help reveal how far and how fast shrinking Antarctic ice could alter coastlines worldwide. The 80 participating researchers point out that continuous gaps in direct observations of seafloor topography in coastal zones and cavities beneath ice shelves currently limit estimations of future ice loss and sea-level rise.
Satellite observations successfully track ice movement and surface changes, but they cannot directly view bedrock situated beneath thick ice sheets, according to information cited from the Alfred Wegener Institute (AWI) via Media Indonesia. Dr. Kenichi Matsuoka, chair of the RINGS Action Group, explained that satellite data alone remains insufficient for accurately forecasting the volume of ice lost to the ocean, while computer models also retain limitations in projecting future ice sheet shifts.
Pro Tip: Coastal planning initiatives rely heavily on narrowing uncertainties in ice sheet dynamics. Integrating direct geophysical measurements with satellite data remains the primary method for improving regional sea-level forecasting models.
Bridging Data Gaps Ahead of International Polar Year
Researchers stress that surveying the entirety of the Antarctic coast requires multi-nation cooperation to prevent missed regions and avoid redundant research efforts. According to the Australian Antarctic Program Partnership (AAPP), this large-scale survey initiative is intended to serve as a stepping stone toward the International Polar Year 2032–2033.
By compiling more comprehensive datasets, scientists expect to refine ice sheet models, making future sea-level projections more reliable for coastal communities worldwide.
Frequently Asked Questions
What is the “RINGS around Antarctica” project?
It is an international geophysical survey plan involving three coordinated pathways circling the Antarctic continent to track land ice flow, grounding zones, and ocean-facing ice shelves.
Why are coastal zones in Antarctica so difficult to monitor?
According to the British Antarctic Survey (BAS) and AWI, satellites cannot directly observe the bedrock or cavities hidden beneath floating ice shelves, creating critical data gaps for computer models.
How many scientists contributed to the recent research review?
According to Reviews of Geophysics reports, 80 scientists from 16 countries collaborated through the SCAR RINGS Action Group to draft the study.
