  • Tarballs on Mumbai Coast

    A beach in South Mumbai, saw black oil-emanating balls lying on the shore.

    What are Tarballs?

    • Tarballs are dark-coloured, sticky balls of oil that form when crude oil floats on the ocean surface.
    • Tarballs are formed by weathering of crude oil in marine environments.
    • They are transported from the open sea to the shores by sea currents and waves.
    • Tarballs are usually coin-sized and are found strewn on the beaches. Some of the balls are as big as a basketball while others are smaller globules.
    • However, over the years, they have become as big as basketballs and can weigh as much as 6-7 kgs.

    How are tarballs formed?

    • Wind and waves tear the oil slick into smaller patches that are scattered over a much wider area.
    • Various physical, chemical and biological processes (weathering) change the appearance of the oil.

    Why are tarballs found on the beaches during the monsoon?

    • It is suspected that the oil comes from the large cargo ships in the deep sea and gets pushed to the shore as tarballs during monsoon due to wind speed and direction.
    • All the oil spilt in the Arabian sea eventually gets deposited on the western coast in the form of tarballs in the monsoon season when wind speed and circulation pattern favour transportation of these tarballs.

  • [pib] Hybodont Shark fossils found in Jaisalmer

    In a rare discovery, teeth of new species of Hybodont shark of Jurassic age have been reported for the first time from Jaisalmer by a team of officers from the Geological Survey of India (GSI).

    Hybodont Shark

    • Hybodonts, an extinct group of sharks, was a dominant group of fishes in both marine and fluvial environments during the Triassic and early Jurassic time.
    • However, hybodont sharks started to decline in marine environments from the Middle Jurassic onwards until they formed a relatively minor component of open-marine shark assemblages.
    • They finally became extinct at the end of the Cretaceous time 65 million years ago.

    Significance of the fossil

    • The newly discovered crushing teeth from Jaisalmer represents a new species named by the research team as Strophodusjaisalmerensis.
    • These sharks have been reported for the first time from the Jurassic rocks (approximately, between 160 and 168 million years old) of the Jaisalmer region of Rajasthan.
    • The genus Strophodus has been identified for the first time from the Indian subcontinent and is only the third such record from Asia, the other two being from Japan and Thailand.
    • It opens a new window for further research in the domain of vertebrate fossils.

  • 124 years of the Battle of Saragarhi

    This September 12 marks the 124th anniversary of the Battle of Saragarhi that has inspired a host of armies, books and films, both at home and abroad.

    What is the Battle of Saragarhi?

    • The Battle of Saragarhi is considered one of the finest last stands in the military history of the world.
    • Twenty-one soldiers were pitted against over 8,000 Afridi and Orakzai tribals but they managed to hold the fort for seven hours.
    • Though heavily outnumbered, the soldiers of 36th Sikhs (now 4 Sikhs), led by Havildar Ishar Singh, fought till their last breath, killing 200 tribals and injuring 600.

    What was Saragarhi, and why was it important?

    • Saragarhi was the communication tower between Fort Lockhart and Fort Gulistan.
    • The two forts in the rugged North-West Frontier Province (NWFP), now in Pakistan. were built by Maharaja Ranjit Singh but renamed by the British.
    • Though Saragarhi was usually manned by a platoon of 40 soldiers, on that fateful day, it was being held by only 21 soldiers from 36th Sikh (now 4 Sikh) and a non-combatant called Daad, a Pashtun who did odd jobs for the troops.
    • Saragarhi helped to link up the two important forts which housed a large number of British troops in the rugged terrain of NWFP.
    • Fort Lockhart was also home to families of British officers.

    What transpired on that day?

    • Around 9 am that day, the sentry at Saragarhi saw a thick haze of dust and soon realized that it was caused by a large army of tribals marching towards the fort.
    • The 8,000 and 15,000 tribals wanted to isolate the two forts by cutting off the lines of communication between them.
    • Unfortunately, the Pathans had cut the supply route between Fort Lockhart and Saragarhi.

    Who was Havildar Ishar Singh who led the troops?

    • Havildar Ishar Singh was born in a village near Jagraon.
    • He joined the Punjab Frontier Force in his late teens after which he spent most of his time on various battlefields.
    • Soon after it was raised in 1887, Ishar was drafted into the 36th Sikhs.
    • He was in his early 40s when he was given independent command of the Saragarhi post.
    • Ishar Singh was quite a maverick who dared to disobey his superiors but he was loved by his men for whom he was always ready to go out on a limb.

    How was the news of the battle received in Britain?

    • Making a departure from the tradition of not giving gallantry medals posthumously, Queen Victoria awarded the 21 dead soldiers — leaving out the non-combatant/
    • They were awarded the Indian Order of Merit (comparable with the Victoria Cross) along with two ‘marabas’ (50 acres) and Rs 500 each.

    How are the slain soldiers remembered?

    • In 2017, the Punjab government decided to observe Saragarhi Day on September 12 as a holiday.
    • Even today the Khyber Scouts regiment of the Pakistani army mounts a guard and salutes the Saragarhi memorial close to Fort Lockhart.

  • Thamirabarani Civilization is 3200 years old

     

    A carbon dating analysis of rice with soil, found in a burial urn at Sivakalai in Thoothukudi district of Tamil Nadu has yielded the date of 1155 BC, indicating that the Thamirabarani civilization dates back to 3,200 years.

    About Thamirabarani River

    • The Thamirabarani or Tamraparni or Porunai is a perennial river that originates from the Agastyarkoodam peak of the Pothigai hills of the Western Ghats.
    • It flows through the Tirunelveli and Thoothukudi districts of the Tamil Nadu state of southern India into the Gulf of Mannar.
    • It was called the Tamraparni River in the pre-classical period, a name it lent to the island of Sri Lanka.
    • The old Tamil name of the river is Porunai.

    Its history

    • Its many name derivations of Tan Porunai include Tampraparani, Tamirabarni, Tamiravaruni.
    • Tan Porunai nathi finds mention by classical Tamil poets in ancient Sangam Tamil literature Purananuru.
    • Recognised as a holy river in Sanskrit literature Puranas, Mahabharata and Ramayana, the river was famed in the Early Pandyan Kingdom for its pearl and conch fisheries and trade.
    • The movement of people, including the faithful, trade merchants and toddy tapers from Tamraparni river to northwestern Sri Lanka led to the shared appellation of the name for the closely connected region.
    • One important historical document on the river is the treatise Tamraparni Mahatmyam.
    • It has many ancient temples along its banks. A hamlet known as Appankoil is located on the northern side of the river.

    Significance of the carbon dating

    • This has provided evidence that there was a city civilisation in south India as long back as 3,200 years ago, the later part of the Indus Valley Civilisation.
    • Vicinity to the ancient port of Muziris, now known as Pattanam, in Kerala add another significance to the trade history of this site.
    • Now, research would be conducted at Quseir al-Qadim and Pernica Anekke in Egypt, which were once part of the Roman empire, as well as in Khor Rori in Oman, to establish the Tamils’ trade relations with these countries.
    • Potsherds bearing Tamil scripts have been found in these countries.
    • Studies would also be conducted in Southeast Asian countries, such as Indonesia, Thailand, Malaysia and Vietnam, where King Rajendra Chola had established supremacy.

  • What is a Solar Storm?

    Studies have found that a powerful solar storm can cause a disruption of the internet, damage submarine cables, and communication satellites.

    What is a Solar Storm?

    • A solar storm or a Coronal Mass Ejection as astronomers call it is an ejection of highly magnetized particles from the sun.
    • These particles can travel several million km per hour and can take about 13 hours to five days to reach Earth.
    • Earth’s atmosphere protects us, humans, from these particles.
    • But the particles can interact with our Earth’s magnetic field, induce strong electric currents on the surface and affect man-made structures.

    History of solar storms

    • The first recorded solar storm occurred in 1859 and it reached Earth in about 17 hours.
    • It affected the telegraph network and many operators experienced electric shocks.
    • A solar storm that occurred in 1921 impacted New York telegraph and railroad systems and another small-scale storm collapsed the power grid in Quebec, Canada in 1989.
    • A 2013 report noted that if a solar storm similar to the 1859 one hit the US today, about 20-40 million people could be without power for 1-2 years, and the total economic cost will be $0.6-2.6 trillion.

    Why is it a cause of concern?

    • The Sun goes through an 11-year cycle – cycles of high and low activity.
    • It also has a longer 100-year cycle.
    • During the last three decades, when the internet infrastructure was booming, it was a low period.
    • And very soon, either in this cycle or the next cycle, we are going towards the peaks of the 100-year cycle.
    • So it is highly likely that we might see one powerful solar storm during our lifetime.

  • Places in news: Qeqertaq Avannarleq Island

    A group of researchers who went out to collect samples off the coast of Greenland in July found themselves on a tiny, uninhabited and previously unknown island.

    Qeqertaq Avannarleq

    • Measuring 60×30 metres and with a peak of three metres above sea level, it has now become the new northernmost piece of land on Earth.
    • Before this, Oodaaq was marked as the Earth’s northernmost terrain.
    • The new island is made up of seabed mud and moraine, i.e. soil, rock and other material left behind by moving glaciers, and has no vegetation.
    • The group has suggested the discovery be named ‘Qeqertaq Avannarleq’, which is Greenlandic for “the northernmost island”.

    How this island came to existence?

    Ans. Undoubtedly, climate change in Greenland

    • Global warming has had a severe effect on the ice sheet of Greenland.
    • The new island, which was exposed by shifting pack ice, is, however, not a direct consequence of climate change.
