Mearim River - Tidal Bore Blog Image

Mearim River - Tidal Bore Latest News

Recently, a Brazilian surfer, known for surfing the world’s longest tidal waves, uses the Mearim’s pororoca to raise awareness about climate change and ecological degradation.

Mearim River

  • The Mearim River is a major river located in Maranhão state, in northern Brazil.
  • It originates in southern Maranhão and drains northward into the Baía de São Marcos (São Marcos Bay), where it forms a common estuary with the Pindaré and Grajaú rivers.
  • The river is ~800 km long, flowing through the Atlantic Coastal Plain marshlands and passing through dense tropical rainforests and mangrove ecosystems.
  • The river's upper and middle courses are marked by rapids, making them non-navigable, while only the lower course is suitable for navigation.
  • The Mearim River forms the southern boundary of the Tocantins–Araguaia–Maranhão moist forests ecoregion, an important biodiversity hotspot.

Tidal Bore (Pororoca) Phenomenon

  • The Mearim River is famous for its pororoca, a tidal bore that occurs when high tides from the ocean travel upstream into the river.
  • The term "pororoca" is derived from the Tupi Indigenous language, meaning "great roar", referring to the thunderous sound generated by the collision of river and ocean waters.
  • A tidal bore is a positive surge of water created when rising ocean tides push against river currents, typically occurring during spring tides and supermoons.
  • The height of the bore is generally greater near the banks of the river than at the centre and can travel upstream for 30 minutes after the peak high tide.
  • The Mearim pororoca is one of the last remaining tidal bores of significant strength in Brazil, attracting surfers and researchers.

Mearim River - Tidal Bore FAQs

Q1: Where is the Mearim River located?
Ans: The Mearim River is located in the Maranhão state of northeastern Brazil and flows into the Atlantic Ocean.

Q2: What unique tidal phenomenon is observed in the Mearim River?
Ans: The Mearim River is known for the tidal bore called the “Pororoca,” where ocean tides push upstream against the river current, creating large waves.

Q3: Which other rivers globally experience tidal bores like the Mearim?
Ans: Rivers like the Amazon (Brazil), Qiantang (China), and Seine (France) also exhibit tidal bores.

Active Galactic Nucleus (AGN) Blog Image

Active Galactic Nuclei (AGNs) Latest News

Astronomers from the Russian Academy of Sciences, using the Spektr-RG (SRG) space observatory, have detected 11 new Active Galactic Nuclei (AGNs) during their all-sky X-ray surveys.

What are Active Galactic Nuclei (AGNs)?

  • Active Galactic Nuclei (AGNs) are compact regions at the centers of galaxies that emit exceptionally high levels of electromagnetic radiation, often outshining the rest of the galaxy.
  • This intense emission arises from either accretion of matter by a supermassive black hole or intense star formation activity.
  • AGNs are among the most luminous and persistent energy sources in the universe and are critical to understanding galaxy formation and evolution.
  • The newly detected AGNs were identified during an optical and X-ray inspection of sources listed in the ARTSS1-5 catalog, using SRG’s ART-XC telescope.
  • The team has also previously identified more than 50 AGNs and several cataclysmic variable stars.

Key Characteristics of the 11 Newly Detected AGNs

  • All 11 AGNs are located at redshifts ranging from 0.028 to 0.258, indicating they are relatively nearby in cosmic terms.
  • Their X-ray luminosities fall within the typical range of 2 to 300 × 10³⁹ erg/s, which is consistent with known AGN profiles.

Classification into Seyfert Types

  • All detected AGNs were classified as Seyfert galaxies, a type of AGN that is common and well-studied:
    • 7 galaxies were classified as Seyfert Type 1 (Sy 1), characterized by broad optical emission lines.
    • 3 galaxies were classified as Seyfert Type 1.9 (Sy 1.9), showing partially broadened lines.
    • 1 galaxy was classified as Seyfert Type 2 (Sy 2), which exhibits narrow emission lines only.
  • Seyfert galaxies appear like normal galaxies in visible light but show strong infrared and X-ray emissions due to activity at their cores.

Active Galactic Nuclei (AGNs) FAQs

Q1: What are Active Galactic Nuclei (AGNs)?
Ans: AGNs are extremely bright central regions of some galaxies, powered by supermassive black holes accreting matter.

Q2: Why are AGNs important in astrophysics?
Ans: AGNs help scientists understand galaxy evolution, black hole activity, and cosmic energy sources across the universe.

Q3: What types of AGNs are there?
Ans: Common types include quasars, blazars, Seyfert galaxies, and radio galaxies, each emitting energy across various wavelengths.

Gamburtsev Subglacial Mountains Blog Image

Gamburtsev Subglacial Mountains Latest News

New data published in Earth and Planetary Science Letters reveals the Gamburtsev Subglacial Mountains (GSM) were formed over 500 million years ago, during the assembly of the Gondwana supercontinent.

What are the Gamburtsev Subglacial Mountains (GSM)?

  • The Gamburtsev Subglacial Mountains are a completely buried mountain range beneath the East Antarctic Ice Sheet, located at its highest point.
  • These mountains were first discovered in 1958 by a Soviet seismic expedition.
  • Unlike the Transantarctic Mountains, which are partially visible above the ice, the Gamburtsev Mountains remain entirely buried, concealed under several kilometres of ice.
  • Typically, mountains form at tectonic plate boundaries due to collision or subduction, but East Antarctica has remained tectonically stable for hundreds of millions of years.
  • The existence of such a massive mountain range within a stable craton posed a major puzzle for geologists.

Zircon “Time Capsules” and Dating Evidence

  • Scientists analysed zircon grains from sandstones deposited by ancient rivers flowing from the mountains, collected from the Prince Charles Mountains.
  • Zircons contain trace uranium, which decays at a known radioactive rate, enabling accurate age determination.
  • Findings show:
    • Uplift began ~650 million years ago
    • Himalayan-scale peaks reached ~580 million years ago
    • Crustal melting and flow ceased ~500 million years ago.

Gamburtsev Subglacial Mountains FAQs

Q1: Where are the Gamburtsev Subglacial Mountains located?
Ans: The Gamburtsev Subglacial Mountains lie beneath the East Antarctic Ice Sheet, completely buried under ice.

Q2: How were these mountains discovered?
