Lost World Under Ice: Antarctica‘s 34-Million-Year-old Landscape Revealed

A Hidden, Ancient Landscape, Untouched for Over 34 Million Years, Has Been Unearthed Deep Beneath The Ice In East Antarctica. scientists Employing Satellite Data and Ice-Penetrating Radar Have Peered Into A Subglacial Realm In Wilkes Land, Revealing Traces Of A World teeming With Rivers, Forests, And Possibly even Palm Trees.

This Revelation offers unprecedented Insights into Antarctica’s Pre-Glacial Past And Could hold Crucial Clues About Our Planet’s Response To Climate Change.

The Discovery In Wilkes Land

Located In The Remote Wilkes land Region Of East Antarctica, The Buried Terrain Lies More Than 1.6 Kilometers (Approximately 1 Mile) Beneath the Ice. This Area, Far From The Coastline And Deep In The Continent’s Interior, Has Remained Shielded From Sunlight And Human Interference For Eons.

Researchers Believe That The Landscape once Covered An Area Exceeding 19,300 Square Kilometers (Over 7,450 Square Miles). pollen Samples Previously Found near The Antarctic Coastline Further Support the Theory Of A Once-Fertile Environment.

Professor Stewart Jamieson Of Durham University, The Study’s Lead Author, Described The Discovery As “Revealing Time Capsules,” Offering A Glimpse Into A World Frozen In Time.

How Antarctica Became A Frozen Desert

Millions Of Years Ago, as The Continents Gradually Shifted, Antarctica Moved towards the South Pole. This Shift Facilitated The Formation Of Powerful Ocean Currents Around The Continent, Effectively Isolating It From Warmer Waters. Simultaneously, Decreasing levels Of Atmospheric Carbon Dioxide Contributed To Global Cooling.

These Combined Factors Initiated The Formation Of A massive Ice Sheet, transforming Antarctica Into The Frozen Desert We Know Today.

According To Professor Jamieson, The Terrain Beneath The East Antarctic Ice Sheet Is Less Explored Than The Surface Of Mars, Highlighting The Significance Of This Discovery.

Features Of The Ancient Landscape

The Study reveals A Dramatic Landscape Characterized By Towering Hills And Frozen Valleys Preserved For Millions Of Years. Researchers Identified Three Prominent High Soil Blocks, Each Ranging From 120 To 168 Kilometers In Length And Up To 85 Kilometers In Width. These Blocks Are Separated By Valleys approximately 40 Kilometers Wide And Nearly 1,188 Meters Deep.

Unlike Glaciers That Typically Erode Underlying Plains,The Ice In East Antarctica Is Exceptionally Cold And Moves Slowly,Less Than 4.8 Meters Per Year. This Sluggish Movement Has Protected The Landscape In Remarkable Detail.

Scientists Refer To This As ‘Cold-Based Ice,’ Where The Ice Is Frozen To The Ground, Minimizing Erosion.

The Significance Of the Discovery

Professor Neil Ross Of Newcastle University, A Co-Author Of The Research, Emphasized The Remarkable Nature Of This Hidden Landscape.He Noted That It Provides Invaluable Insights Into The initial And Long-Term history Of The East Antarctic ice Sheet, as Well As Its Potential Response To future Climate Change.

Researchers Utilized Satellite Images To Detect Subtle Surface Protrusions And Employed Computer Models To Track Landscape changes Over Time. Some Areas Of The Buried Terrain Have Been Lifted By Up To 487 meters Due To The Weight Of The Ice, further Preserving This Unique Environment.

This Preserved Terrain Offers A Rare Window Into Antarctica’s Past, Before The Ice Sheet Enveloped The Continent.

A Glimpse Into Antarctica’s Past

The Landscape Resembles A Surface Formed By Rivers Before The Advent Of Ice, suggesting The Region Once Boasted Flowing Rivers And Dense Forests flourishing In A Moderate Climate.

As The Ancient Supercontinent Gondwana Began To Break Apart, Deep Cracks And Gaps Formed, Possibly Dividing The Highlands Into Distinct Blocks Before Glaciers Arrived.

Over Time, Cooling Temperatures And Small Glaciers Carved Deeper Valleys, Creating The Classic U-Shaped Formations Characteristic Of Mountain Glaciation.

The Frozen Landscape Persists

Approximately 14 Million Years Ago, the Expanding East Antarctic Ice Sheet Engulfed The Entire Area. Even During Warmer Periods, Such As The Mid-Pliocene Around 3 Million Years Ago, The Region Remained Frozen.

Although The Surrounding Ice May Have Partially Melted During These Warmer intervals, It Was Insufficient To Expose the Ancient Terrain.

This Makes The Discovery Notably Pertinent Today, as Earth Approaches Carbon Dioxide Levels And Temperatures Unseen As The Ice-Free Era.

Scientists Caution That Continued Global Warming Could Lead To The Shrinkage Of The Ice Sheet, Although drilling Through More Than 1.6 Kilometers Of solid Ice To Reach The Hidden Landscape Would Require Substantial Time, Resources, And investment.

Professor Jamieson Affirmed The Commitment To Continued Exploration, Aiming To Fill Data Gaps And Understand How The ice Sheet And Underlying Landscape Have Evolved Over Their Extensive History.

Key Features of the buried Landscape

Size	>19,300 square kilometers	Vast, potentially holding significant data
Landscape	Towering hills, frozen valleys, former rivers & forests	Preserved in detail due to slow-moving, cold-based ice
Age	34+ million years	Provides a snapshot of pre-glacial Antarctica

Implications For Understanding Climate Change

This Discovery Holds Monumental Importance For Several Reasons:

• Climate History: Understanding Antarctica’s Past Climate Conditions can Help Us Better Predict future Climate Scenarios.
• Ice Sheet Stability: Studying The Interactions Between The Ice Sheet And The Underlying Landscape Can provide Insights Into Ice Sheet Stability.
• Biodiversity: The Discovery Raises Intriguing Questions About What Life Forms May Have Existed In This environment Millions Of Years Ago.

Did You Know? Antarctica Holds Approximately 90% Of The World’s Ice And 70% Of the World’s Fresh Water. If all The Ice Melted, Global Sea Levels Would Rise By About 60 Meters (200 Feet).

Further Research And Exploration

Scientists Are Planning Further Investigations To Gain An Even Deeper Understanding Of This Remarkable Landscape.

• Drilling: Future Missions May Involve Drilling Through The Ice Sheet To collect Samples And Conduct On-Site Research.
• advanced Imaging: Utilizing More Advanced Imaging Techniques Will Help Map The Landscape In Greater Detail.
• Modeling: Enhanced Climate Models Will Incorporate This New Data To Improve Our Understanding Of Climate Change.

Pro Tip: Stay Informed About The Latest Climate Research By Following Reputable Scientific Journals And Organizations Such As The Intergovernmental Panel On Climate Change (IPCC) And The National Oceanic And Atmospheric Administration (NOAA).
