Analysis of Plate Spin Motion and Its Implications for Strength of Plate Boundary Takeshi Matsuyama1 and Hikaru Iwamori1,2*
Matsuyama and Iwamori Earth Planet Sp (2016) 68:36 DOI 10.1186/s40623-016-0405-5 LETTER Open Access Analysis of plate spin motion and its implications for strength of plate boundary Takeshi Matsuyama1 and Hikaru Iwamori1,2* Abstract In this study, we investigate the driving forces of plate motion, especially those of plate spin motion, that are related to the toroidal components of the global plate velocity field. In previous works, numerical simulations of mantle convection have been used to examine the extent to which toroidal velocity components are naturally generated on the surface, by varying key parameters, notably the rheological properties of plates and plate boundaries. Here, we take the reverse approach and perform analyses of observed plate motions, which show an increase in the toroidal/ poloidal ratio at high degrees of spherical harmonic expansion, as well as a rapid change in the plate spin rate and the estimated driving stress around a critical plate size of approximately 1000 km. This quantitative relationship constrains the strength at plate boundaries to 3–75 MPa, which is consistent with several seismological observations, including those from the NE Japan arc associated with the 2011 Tohoku earthquake.

Delving Deeper Critical Challenges for 21St Century Deep-Sea Research
EUROPEAN MARINE BOARD Delving Deeper Critical challenges for 21st century deep-sea research Position Paper 22 Wandelaarkaai 7 I 8400 Ostend I Belgium Tel.: +32(0)59 34 01 63 I Fax: +32(0)59 34 01 65 E-mail: [email protected] www.marineboard.eu www.marineboard.eu European Marine Board The Marine Board provides a pan-European platform for its member organizations to develop common priorities, to advance marine research, and to bridge the gap between science and policy in order to meet future marine science challenges and opportunities. The Marine Board was established in 1995 to facilitate enhanced cooperation between European marine science organizations towards the development of a common vision on the research priorities and strategies for marine science in Europe. Members are either major national marine or oceanographic institutes, research funding agencies, or national consortia of universities with a strong marine research focus. In 2015, the Marine Board represents 36 Member Organizations from 19 countries. The Board provides the essential components for transferring knowledge for leadership in marine research in Europe. Adopting a strategic role, the Marine Board serves its member organizations by providing a forum within which marine research policy advice to national agencies and to the European Commission is developed, with the objective of promoting the establishment of the European marine Research Area. www.marineboard.eu European Marine Board Member Organizations UNIVERSITÉS MARINES Irish Marine Universities National Research Council of Italy Consortium MASTS Delving Deeper: Critical challenges for 21st century deep-sea research European Marine Board Position Paper 22 This position paper is based on the activities of the European Marine Board Working Group Deep-Sea Research (WG Deep Sea) Coordinating author and WG Chair Alex D. -

Seafloor Spreading and Plate Tectonics
OCN 201: Seafloor Spreading and Plate Tectonics I Revival of Continental Drift Theory • Kiyoo Wadati (1935) speculated that earthquakes and volcanoes may be associated with continental drift. • Hugo Benioff (1940) plotted locations of deep earthquakes at edge of Pacific “Ring of Fire”. • Earthquakes are not randomly distributed but instead coincide with mid-ocean ridge system. • Evidence of polar wandering. Revival of Continental Drift Theory Wegener’s theory was revived in the 1950’s based on paleomagnetic evidence for “Polar Wandering”. Earth’s Magnetic Field Earth’s magnetic field simulates a bar magnet, but it is caused by A bar magnet with Fe filings convection of liquid Fe in Earth’s aligning along the “lines” of the outer core: the Geodynamo. magnetic field A moving electrical conductor induces a magnetic field. Earth’s magnetic field is toroidal, or “donut-shaped”. A freely moving magnet lies horizontal at the equator, vertical at the poles, and points toward the “North” pole. Paleomagnetism in Rocks • Magnetic minerals (e.g. Magnetite, Fe3 O4 ) in rocks align with Earth’s magnetic field when rocks solidify. • Magnetic alignment is “frozen in” and retained if rock is not subsequently heated. • Can use paleomagnetism of ancient rocks to determine: --direction and polarity of magnetic field --paleolatitude of rock --apparent position of N and S magnetic poles.

Climate Change Impacts on the Distribution of Coastal Lobsters
Marine Biology (2018) 165:186 https://doi.org/10.1007/s00227-018-3441-9 SHORT NOTE Climate change impacts on the distribution of coastal lobsters Joana Boavida‑Portugal1,2 · Rui Rosa2 · Ricardo Calado3 · Maria Pinto4 · Inês Boavida‑Portugal5 · Miguel B. Araújo1,6,7 · François Guilhaumon8,9 Received: 17 January 2018 / Accepted: 26 October 2018 / Published online: 16 November 2018 © Springer-Verlag GmbH Germany, part of Springer Nature 2018 Abstract Coastal lobsters support important fsheries all over the world, but there is evidence that climate-induced changes may jeopardize some stocks. Here we present the frst global forecasts of changes in coastal lobster species distribution under climate change, using an ensemble of ecological niche models (ENMs). Global changes in richness were projected for 125 coastal lobster species for the end of the century, using a stabilization scenario (4.5 RCP). We compared projected changes in diversity with lobster fsheries data and found that losses in suitable habitat for coastal lobster species were mainly projected in areas with high commercial fshing interest, with species projected to contract their climatic envelope between 40 and 100%. Higher losses of spiny lobsters are projected in the coasts of wider Caribbean/Brazil, eastern Africa and Indo-Pacifc region, areas with several directed fsheries and aquacultures, while clawed lobsters are projected to shifts their envelope to northern latitudes likely afecting the North European, North American and Canadian fsheries. Fisheries represent an important resource for local and global economies and understanding how they might be afected by climate change scenarios is paramount when developing specifc or regional management strategies. -

Balasubramanian University of Mysore 19-11-2011 Introduction Earth’s environmental segments include Atmosphere, Hydrosphere, lithosphere, and biosphere. Lithosphere is the basic solid sphere of the planet earth. It is the sphere of hard rock masses. The land we live in is on this lithosphere only. All other spheres are attached to this lithosphere due to earth’s gravity. Lithosphere is a massive and hard solid substratum holding the semisolid, liquid, biotic and gaseous molecules and masses surrounding it. All geomorphic processes happen on this sphere. It is the sphere where all natural resources are existing. It links the cyclic processes of atmosphere, hydrosphere, and biosphere. Lithosphere also acts as the basic route for all biogeochemical activities. For all geographic studies, a basic understanding of the lithosphere is needed. In this lesson, the following aspects are included: 1. The Earth’s Interior. 2. -

The processes influencing species diversification under 21 environmental change remain one of the central focal points of evolutionary biology, particularly for marine 22 organisms with high dispersal potential. We investigated genome-wide divergence, introgression patterns and 23 inferred demographic history between species pairs of all extant rock lobster species (Jasus spp.), a complex 24 with long larval duration, that has populated continental shelf and seamount habitats around the globe at 25 approximately 40oS. -
