    deccan

    Central Idea

    • A team of scientists from IIT Kharagpur has discovered evidence of exceptionally high annual rainfall during the volcanic activity that formed the Deccan Traps in India around 66 million years ago.
    • Using a new technique called Nanoscale Secondary Ion Mass Spectrometry (NanoSIMS), the researchers analyzed the isotopic composition of fossil trees from the Cretaceous period.
    • They determined the isotopic composition of the rainfall-derived lake water.

    Nanoscale Secondary Ion Mass Spectrometry (NanoSIMS)

    • NanoSIMS is an advanced analytical technique to determine the composition and distribution of elements and isotopes at a microscopic scale.
    • It allows for high-resolution imaging and quantitative analysis of samples.
    • The technique involves bombarding the sample surface with a focused beam of primary ions.
    • This causes the ejection of secondary ions from the sample surface.
    • The secondary ions are collected and analyzed using a mass spectrometer.
    • The mass spectrometer separates the ions based on their mass-to-charge ratio and measures their abundance.

    Analysis and Findings

    • New Technique: The team used Nanoscale Secondary Ion Mass Spectrometry to analyze oxygen isotopes in fossil trees and measure the isotopic composition of the lake water derived from rainfall.
    • Depleted Oxygen Isotopes: The analysis revealed depleted oxygen isotope values, indicating higher tropical rainfall in India during the terminal Cretaceous period.
    • Link to Paleoclimatic Changes: The increase in rainfall closely corresponded to changes in paleo-atmospheric carbon dioxide levels, suggesting a potential underlying link between the two.

    Implications and Comparison

    • Atmospheric Carbon Dioxide Concentration: The eruption of Deccan Trap lavas released a significant amount of carbon dioxide, raising atmospheric levels to as high as 1,000 ppm.
    • Comparison to Modern Rainfall: The data from fossil trees indicated an annual rainfall of 1,800-1,900 mm, exceeding the average modern rainfall of 1,000-1,200 mm in most parts of peninsular India.
    • Climate Change Predictions: The findings align with predictions made by the Intergovernmental Panel on Climate Change (IPCC) for extreme warming scenarios, suggesting a correlation between high carbon dioxide levels and increased rainfall.

    Climate Models and Future Projections

    • Rising Carbon Dioxide Levels: Fossil fuel emissions have raised carbon dioxide levels from 280 ppm to about 420 ppm in 2023.
    • Impact on Rainfall: Climate models indicate that doubling carbon dioxide levels will intensify atmospheric circulation and subsequently increase rainfall.
    • IPCC AR6 Report: The report warns of a significant increase in the wettest day precipitation and tropical cyclone-associated rainfall if carbon dioxide emissions continue to rise unabated.

    Conclusion

    • The study provides evidence of high rainfall during the volcanic activity that formed the Deccan Traps in India millions of years ago.
    • The findings suggest a correlation between elevated carbon dioxide levels and increased rainfall, supporting predictions made by climate models for future climate change scenarios.

     

  • Gravity Hole in the Indian Ocean

    gravity hole
    The true shape of our Earth

    Central Idea

    • One intriguing phenomenon recently discovered is the presence of a significant “gravity hole” in the Indian Ocean, where the gravitational pull is notably weaker.
    • Recent research sheds light on the possible causes behind this anomaly.

    What is a Gravity Hole?

    • A “gravity hole” refers to a region on Earth where the gravitational pull is significantly weaker compared to the surrounding areas or the global average.
    • It is characterized by a dip or low gravity anomaly.
    • In such areas, the sea level may be lower than average due to the weaker gravitational force acting upon the water.
    • This term is often used to describe specific locations, such as the Indian Ocean geoid low (IOGL), where the gravitational pull is notably diminished compared to nearby regions.
    • The exact causes of gravity holes can vary and may involve factors such as variations in the Earth’s mass distribution or underlying geological features.

    What is Indian Ocean Geoid Low (IOGL)?

    • It is located approximately 1,200 kilometers southwest of the southernmost tip of India.
    • IOGL is an area in the Indian Ocean where the sea level is about 106 meters below the global average.

    Unraveling the Causes of IOGL

    • Discovering the Anomaly: Geophysicist Felix Andries Vening Meinesz first identified the IOGL during a survey in 1948. Since then, it has been confirmed by subsequent ship-based experiments and satellite measurements.
    • Ancient Ocean Hypothesis: Researchers from the Indian Institute of Science conducted computer-simulated models spanning 140 million years. They discovered remnants of an ancient ocean, located approximately 965 kilometers below the Earth’s crust, just beneath Africa.
    • Molten Rock Plumes: The simulations revealed molten rock plumes below Africa, potentially caused by tectonic plates subducting into the mantle. These plumes are believed to be a contributing factor to the IOGL.
    • Possible origination: Researchers said that the IOGL comprises slabs from the Tethys Sea, a long-lost sea that plunged into the depths of the planet millions of years ago. Tethys Sea, which once separated the supercontinents of Gondwana and Laurasia is believed to have perturbed the African Large Low Shear Velocity province.

    Future Perspectives

    • Lack of Seismic Evidence: While the simulated models suggest the presence of molten rock plumes beneath the Indian Ocean, seismographic evidence has yet to confirm their actual existence.
    • Additional Factors at Play: The researchers emphasize that other factors contributing to the gravitational anomaly in the Indian Ocean need to be further explored before reaching a definitive conclusion.
    • Further Research: Continuation of studies, including seismic surveys and detailed modelling, is necessary to gain a comprehensive understanding of the IOGL and its causes.

  • Groundwater extraction shifted the Earth’s axis: What a new study says

    Groundwater

    Central Idea

    • In a recent study, researchers have revealed that human activities, particularly the extraction of groundwater, have had a discernible impact on Earth’s axis and contributed to the rise in global sea levels. This phenomenon, known as polar motion, occurs as the mass distribution within and on the planet changes. While the shift in the axis may not have immediate real-life consequences, it underscores the significant influence of human actions on our planet’s delicate balance.

    *Relevance of the topic:

    *Important geological phenomenon and Contribution of human activities to climate change and its impact

    *Also, recent new research suggests that Earth’s inner core may now be rotating slower than its surface, potentially indicating a change in its rotational dynamics

    *Quick facts for prelims on geological phenomenon

    The phenomenon of Earth’s rotation

    • Rotation Axis: The Earth rotates around an imaginary line called the rotation axis, which runs through the North Pole, the center of the Earth, and the South Pole. This axis remains fixed in space, and the Earth completes one full rotation around it in approximately 24 hours.
    • Rotation Direction: The Earth rotates from west to east, which is why we perceive the sun and other celestial objects to rise in the east and set in the west.
    • Speed of Rotation: The Earth rotates at a relatively constant speed. The equator experiences the fastest rotational speed, which is approximately 1,670 kilometers per hour (1,040 miles per hour). The rotational speed gradually decreases towards the poles.
    • Effects of Rotation:
    1. Day and Night: As the Earth rotates, different parts of the planet are exposed to sunlight, creating the cycle of day and night.
    2. Coriolis Effect: The rotation of the Earth influences the movement of air and ocean currents, giving rise to the Coriolis effect. This effect causes moving objects (such as winds and ocean currents) to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
    3. Shape of the Earth: Earth’s rotation causes it to bulge slightly at the equator and flatten at the poles, resulting in an oblate spheroid shape.
    4. Centrifugal Force: The rotation generates a centrifugal force that slightly counteracts the force of gravity, leading to a slightly lower effective gravity at the equator compared to the poles.
    • Polar Motion: Earth’s axis and the location of the poles are not fixed and can undergo slight movements. This phenomenon, known as polar motion, occurs due to various factors, including mass redistribution within the Earth, changes in water distribution, and atmospheric pressure variations.

    The new findings of the study on the impact of groundwater extraction on Earth’s axis

    • Groundwater Extraction and Axis Shift: The study revealed that groundwater extraction plays a significant role in the shift of Earth’s rotational axis. The redistribution of groundwater resulting from activities like irrigation and meeting freshwater demands was found to be the largest contributor to the drift of the rotational pole.
    • Impact of Midlatitude Groundwater Extraction: The research showed that groundwater extraction from regions located at the Earth’s midlatitudes, specifically North America and northwestern India, had a more pronounced effect on polar motion compared to extraction taking place at the poles or equator. This finding highlights the sensitivity of the rotational pole to mass changes in midlatitude areas.
    • Contribution to Sea Level Rise: The study confirmed that groundwater extraction is a major contributor to the rise in global sea levels. The water extracted from the ground for various purposes eventually finds its way into the oceans. The researchers’ calculations aligned with previous studies, which estimated that groundwater extraction raised global sea levels by 6.24mm between 1993 and 2010

    Impact of Climate Change on Polar Motion

    • Changes in Water Mass Distribution: Climate change is causing significant changes in the distribution of water masses on Earth. The melting of glaciers, ice sheets, and polar ice caps contributes to the redistribution of water from land to the oceans. This alteration in water mass distribution affects the planet’s rotational dynamics, including polar motion.
    • Melting of Greenland’s Ice: Greenland’s ice sheet is particularly susceptible to climate change. As it melts, vast amounts of water are discharged into the surrounding oceans. This influx of water alters the distribution of mass on Earth, leading to shifts in the rotational axis.
    • Accelerated Rotational Axis Shift: Recent studies suggest that climate change has accelerated the shift of Earth’s rotational axis since the 1990s. The increased melting of glaciers and ice sheets, combined with other climate-driven changes in water distribution, has intensified the movement of the rotational axis compared to historical patterns.
    • Influence on Polar Motion Magnitude: Climate-driven changes in water mass distribution have been found to have a significant impact on the magnitude of polar motion. The redistribution of water, particularly from the melting of ice, affects the planet’s overall mass distribution, causing shifts in the rotational pole.

    What is the Significance of the Study?

    • Understanding Human Influence: The study highlights the significant influence of human activities, specifically groundwater extraction, on Earth’s rotational dynamics and polar motion.
