InterRidge fellow 2017

The InterRidge Student and Postdoctoral Fellowship Programme continues to play an important role in the careers of early career ocean scientists. There was a high number of proposals submitted again this year and we awarded four InterRidge-funded Fellowships, together with three Fellowships for students from developing countries, supported by the ISA Endowment Fund.

The recipients of this year's InterRidge Fellowships are:

Egidio Marino - a post-doctoral researcher at the Geological Survey of Spain

Julia Machon - a PhD Student at the Pierre and Marie University in Paris, France

Inmaculada Frutos - a post-doctoral researcher at the University of Hamburg, Germany

Guangyu Xu - a post-doctoral researcher at the University of Washington, USA

InterRidge/ISA Endowment Fund Fellowships were awarded to:

Seyedeh Elnaz Naghibi - a post-doctoral researcher at School of Engineering and Materials Science, Queen Mary University of London, UK
Surya Prakash - a post-doctoral researcher at the National Centre for Antarctic and Ocean Research, India

Egidio Marino

Egidio Marino is Graduated in Geology in Complutense University of Madrid (2013) and got his Master in Geologic Resources and Processes in the same University (2014). In October 2015 won a FPU PhD Grant and actually is advancing its research in strategical elements and polymetallic submarine crusts in the Crystallography and Mineralogy Department of Geology Faculty, in the Complutense University of Madrid in collaboration with the Geological Survey of Spain (IGME).

Preliminary results of his work have been recently published in a paper in Ore Geology Review (Strategic and rare elements in Cretaceous-Cenozoic cobalt-rich ferromanganese crusts from seamounts in the Canary Island Seamount Province (northeastern tropical Atlantic) . Ore Geology Review, 87, 41-61). In 2017 won an additional grant to visit the Bundesanstalt für Geowissenschaften und Rohstoffe (BGR) of Hannover in which he spent almost 3 months making high resolution experiments to identify the mineralogy and geochemistry of several samples from Canary Island Seamount Province (CISP).

Egidio has participated in the Oceanographic Expedition SUBVENT1 (2013) supported by IGME and in Deep Links Cruise (2015) organized by the Irish Marine Institute (Galway, Ireland), and is waiting for the next expedition EXPLO-SEA  scheduled for the end of 2018. He is expert in several experiments and tasks: mineral recognition with optical microscope, XRD characterization, geochemical studies useful to his PhD thesis that usually perform in the Geological Survey of Spain (IGME) laboratories.

His principal research lines are related with Mineralogy, Geochemistry, Petrology and Metallogenesis, especially related with Submarine Fe-Mn mineralizations: Cobalt rich polymetallic crusts, Growth rates and ages of submarine deposits performed with different methods: Cobalt chronometer, isotopic age (Nd, Sr, Pb and Os), Strategic elements and rare metals in submarine minerals.

His Project granted by InterRidge it arises to search hydrothermal influences from the Mid Atlantic Ridge or the Canary Island Hot Spot on the formation of Ferromanganese crusts from CISP using  high resolution analysis, essentially isotopic and geochemical high resolution data performed with LA-ICP-MS and EPMA.

Seyedeh Elnaz Naghibi

Elnaz Naghibi earned her PhD in Mechanical Engineering from Sharif University of Technology in 2017 and is currently a Teaching Associate in Queen Mary, University of London. Her PhD thesis was on "Interactions of large-scale oceanic currents and the Earth's Chandler wobble" in which she investigated how Chandler wobble, as a natural mode of the Earth, interacts with oceanic turbulence. She developed a simple yet physically insightful semi-analytical model of how the mesocopic ocean turbulence in the North Atlantic Ocean can act as a forcing for the Chandler wobble. The work has led to fast turn-around semi-analytical solutions which allowed her to quickly cover a wide range of model parameters to answer the question – does the wobble response to the oceanic forcing provide a feedback to the oceanic circulation? 
Following her PhD research, she was awarded InterRidge Postdoctoral Fellowship for a new project on "Understanding the effect of bottom topography on the dynamics of the Southern Ocean and Chandler wobble using an eddy-resolved ocean dynamics model" in 2017. The project is a collaboration between Queen Mary University of London and Rosenstiel School of Marine and Atmospheric Science, University of Miami supervised by Dr. Sergey Karabasov and Prof Igor Kamenkovich. In this project, the effect of bottom topography on the dynamics of the zonal flows in the Southern Ocean will be investigated using an eddy-resolved ocean model and the influence of the resulting oceanic currents on Chandler wobble is going to be studied. A two-way coupled semi-analytical model for interactions of Chandler wobble and ocean dynamics will as well be developed and tested with the eddy-resolved model to analyze the feedback effect of the Earth’s wobbling motion onto oceanic currents. Furthermore, the role of the Southern Ocean in the excitation of Chandler wobble will be compared with that of the North Atlantic.
