Egidio Marino (a PhD student at the Geological Survey of Spain, Spain)
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.
Julia Machon (a PhD student at the Pierre and Marie University in Paris, France)
I applied for the InterRidge fellowship program as a PhD student to initiate a research project with a laboratory abroad, which ended on a successful collaboration and has extended the deep sea research community.
Briefly, I conducted my PhD at Sorbonne Université (Paris, France) in the “Adaptations to Extreme Environments” team, to focus on the sensory abilities of shrimps living at deep hydrothermal vents. The hydrothermal environment is characterized by fairly hostile (from a human perspective) physico-chemical conditions, darkness and high hydrostatic pressure, and how vent shrimps cope with these features and sense their environment is of major interest in deep sea biology.
To investigate whether vent shrimps present sensory adaptations in relation with their lifestyle, I studied the olfactory system in several vent species from the Mid-Atlantic Ridge (Rimicaris exoculata, Rimicaris chacei, Mirocarisfortunata and Alvinocaris markensis), in comparison with a shallow-water species (Palaemon elegans). In the course of this research, a logical follow-up was to consider their central nervous system, because the brain structure can provide interesting hints about the sensory abilities and lifestyle of an animal.
Thanks to the InterRidge Fellowship, I could spend one month at the University of Greifswald (Germany), at the Cytology and Evolutionary Biology department which has a strong expertise in crustacean neuroanatomy. Using specimens sampled during the BICOSE2 cruise (2018, Ifremer), we conducted a comparative study on the brain architecture of vent and shallow-water shrimps, using classical histology, immunochemistry and 3D-reconstructions from X-ray micro-computed tomography scans.
Inmaculada Frutos (a post-doctoral researcher at the University of Hamburg, Germany)
Inmaculada Frutos obatained her PhD from the University of Alcala in Spain (2006) after a pioneer study on the subtidal suprabenthic communities in the NE Atlantic waters of Spain. Her research is mainly focused on the characterization of suprabenthic crustaceans (mainly peracarids) in deep-sea waters: study of biodiversity within an ecological approach, spatial and temporal evolution of assemblages in relation to abiotic variables and its trophic role in the marine benthic food webs. All of them within a robust systematic knowledge which achieves the description of new species.
After her PhD degree, she has enhanced her qualification while studying peracarid collections (Amphipods, isopods, mysids, cumaceans and tanaids) in numerous international European Institutions as: Spanish Institute of Oceanography (La Coruna and Santander, Spain), University of Bordeaux (Marine Station Arcachon, France) , Center for Environment, Fisheries and Aquaculture Science (CEFAS Lowestoft, UK), Zoologisches Museum der Universitat Hamburg (Germany), Museum national d’Histoire Naturelle (Paris, France), University of Lodz (Poland), Ifremer (Brest, France). Her research comprises her active participation in expeidtions, mainly working with benthic sledges: she has already worked on the sea for more than 30 expeditions carried out mainly in the NE Atlantic Ocean (North Sea, Bay of Biscay, off NW Iberian Peninsula, tropical N Atlantic and Puerto Rio Trench), but also in the NW Pacific (Sea of Okhotsk and Kuril-Kamchatka area).
She is specially interested in the diversity and connectivity of deep-sea Atlantic peracarids. During her post-doc at the Zoological Museum of the University of Hamburg, she is investing the abyssal suprabenthic community in the tropical N Atlantic along a latitudinal transect at both sides of the Vema Fracture located in the Mid Atlantic Ridge (MAR). With the InterRidge Fellowship her knowledge enhance into the field of hydrothermal vents and broaden her understanding of the deep-sea communities of the deep Atlantic Ocean. The opportunity of joining the BICOSE2 expedition, has allowed to sample and characterize the suprabenthic communities of the hydrothermal TAG site providing a strong baseline to study the ecology of the fauna inhabitant this place in the MAR. Gaining insight into these communities it would outline the possible connectivity along the MAR.
Seyedeh Elnaz Naghibi (a post-doctoral researcher at School of Engineering and Materials Sciences, Queen Mary University of London, UK)
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 mesoscopic 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 circluation?
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 botton 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 Chanlder 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 North Atlantic.
Surya Prakash (a post-doctoral researcher at the National Center for Antarctic and Ocean Research, India)
After completion of Master’s degree in Chemistry from Jiwaji University, India, I joined the Ridge research program at CSIR-National Institute of Oceanography, Goa, India. The main objective of the program is to study the various hydrothermal processes and associated mineralization along the Indian Ridge system with special emphasis on Carlsberg and Central Indian Ridges. I have participated in several ridge cruises with the objective to study water column chemical signatures for the identification of hydrothermal plumes. During my first cruise onboard RV SONNE; I was very excited when I saw the turbidity signatures in the deep waters. Water samples from these turbid plume layers were collected by us for helium isotope studies, which is considered a good tracer for hydrothermal plume identification. The analysis was carried out with Dr. Lupton at NOAA-Pacific Marine Environmental Laboratory, Newport, USA. This study was supported by International Seabed Authority (ISA) endowment fund for the year 2009. Simultaneously, for my doctoral thesis, I have worked on “origins and geochemistry of ferromanganese encrustations from Indian Ocean”. After completion of my doctoral thesis, I have joined the research group at National Centre for Antarctica and Ocean Research (NCAOR).
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.
