Davies ([email protected]) Received: 7 October 2019 – Discussion started: 25 October 2019 Revised: 3 February 2020 – Accepted: 8 February 2020 – Published: 20 March 2020 Abstract. The Earth is currently 180 Myr into a supercontinent cycle that began with the break-up of Pangaea and which will end around 200–250 Myr (million years) in the future, as the next supercontinent forms. As the continents move around the planet they change the geometry of ocean basins, and thereby modify their resonant properties. In doing so, oceans move through tidal resonance, causing the global tides to be profoundly affected. Here, we use a dedicated and established global tidal model to simulate the evolution of tides during four future supercontinent scenarios. We show that the number of tidal resonances on Earth varies between one and five in a supercontinent cycle and that they last for no longer than 20 Myr.

  • Mantle Plumes and Mantle Dynamics in the Wilson Cycle
    Mantle plumes and mantle dynamics in the Wilson cycle PHILIP J. HERON Department of Earth Sciences, Durham University, Elvet Hill, Durham DH1 3LE, UK 0000-0002-4813-0504 [email protected] Abstract: This review discusses the thermal evolution of the mantle following large-scale tectonic activities such as continental collision and continental rifting. About 300 myr ago, continental material amalgamated through the large-scale subduction of oceanic seafloor, marking the termination of one or more oceanic basins (e.g. Wilson cycles) and the formation of the supercontinent Pangaea. The present day location of the continents is due to the rifting apart of Pangaea, with the dispersal of the supercontinent being characterized by increased volcanic activity linked to the generation of deep mantle plumes. The discussion presented here investigates theories regarding the thermal evolution of the mantle (e.g. mantle temperatures and sub-continental plumes) following the formation of a supercontinent. Rifting, orogenesis and mass eruptions from large igneous prov- inces change the landscape of the lithosphere, whereas processes related to the initiation and termination of oce- anic subduction have a profound impact on deep mantle reservoirs and thermal upwelling through the modification of mantle flow. Upwelling and downwelling in mantle convection are dynamically linked and can influence processes from the crust to the core, placing the Wilson cycle and the evolution of oceans at the forefront of our dynamic Earth. The theory of plate tectonics describes the movement proposed a cycle describing the opening and closing of the Earth’s lithosphere, while the convective of oceanic basins, and therefore a method of amal- motion of the Earth’s mantle drives the tectonic gamating continental material that would subse- plates to determine the present day position of the quently be dispersed.

In the presence of Her Royal Highness Princess Astrid our institute celebrated its hundredth birthday, a festive event which illustrated once more that ITM has indeed acquired an enviable reputation with regard to education, research and the provision of services in tropical health care. We were most pleased that directors of our partner institutions worldwide, as well as the chairmen of important international organizations, amongst whom also our former professor Dr. Peter Piot, director of UNAIDS, travelled to Antwerp to partake in the celebrations. It proves how much the efforts of our institute are appreciated. The undisputed highlight of the jubilee, however, was the official opening of our brand new teaching campus at the beautifully renovated 7th century Capuchin convent. Once a forgotten piece of Antwerp, today it is a marvellous campus, which will not only make a lasting impression on our students, but will also contribute to the dynamism of our institute.

    Uncommon Knowledge.indd 3 14/08/2019 15:56 Untitled-2 1 29/11/2017 16:30 Introduction: The joy of uncommon knowledge “EVERYTHING THAT IS NEW or uncommon raises a pleasure in the imagination,” wrote Joseph Addison, an English essayist and poet, “because it fills the soul with an agreeable surprise, gratifies its curiosity, and gives it an idea of which it was not before possessed.” He was writing in 1712, but today, more than three centuries later, his remark neatly summarises the objective of this book. This is a compendium of explanations, and what they all have in common is that they are uncommon: a word that has two meanings. On the one hand, it refers to things that are rare or infrequently encountered. In the realm of knowledge, that means things that not many people are aware of or know about. But these unusual explanations also have the power to stretch your mind and subtly change how you see the world. In other words, they are uncommon in the second sense of the word, which means exceptional and extraordinary. As Addison observed, uncommon knowledge is enjoyable to encounter because it is unexpected and surprising; because a neat explanation is mentally satisfying; and because encountering a previously unfamiliar idea, and storing it away for future reference, expands the intellect. Many people would be surprised to hear that the global suicide rate is falling; that most refugees do not live in camps; that carrots were not originally orange; or that the far side of the Moon isn’t always dark.
