Report of Guest PhD student Grasiane Luz Mathias about her research placement at MARUM from May - July 2014
Using the assistance provided by GLOMAR it was possible to visit Bremen between May and October of 2014 and work with the research group of Marine Geophysics, in the Department of Geosciences (FB5) of the University of Bremen. Professor PhD Tilo von Dobeneck, which is the head of this research group and lead the Laboratory for Paleo-, Rock and Environmental Magnetism (“Paleomag Lab”), kindly supervised me during my stay.
The work I developed during this visit concerns my PhD project, whose theme is to study the paleo -climate and -circulation in the coast off NE Brazil in the past. This theme is being widely studied by another workgroups at MARUM addressing a better understanding about processes that take place in the continental margin off Amazon River. The cores I am using belong to the IODP Core Repository of the University of Bremen. They were collected during the Meteor Cruise M34/4, 1996.
In my PhD thesis, I use environmental magnetism, and secondarily major elements. In my first visit to Bremen (2012-2013), I have used the facilities of the “Paleomag Lab” to perform magnetic measurements in the cores GeoB3911-3, GeoB3912-1 and GeoB3913-3. Moreover, I obtained major element data for these cores using the facilities of the XRF Core Scanners Laboratory of MARUM. The data we obtained provided us new clues about sediment dynamics in the coast off NE Brazil.
During these two and a half months I spent in Bremen, we performed magnetic measurements in another core (GeoB3910-2) collected in the same cruise, and we started to write a scientific paper about sediment transport along the coast off NE Brazil. The paper in now in preparation and we will be submit it soon to a scientific journal.
I am very grateful to GLOMAR for the financial support and the opportunity of such a fruitful experience. I would like to thank also for the laboratory facilities and apprenticeship. It was a great experience to work close together with experts in my research theme. This experience gave rise to a new scientific cooperation between Institute of Astronomy, Geophysics and Atmospheric Sciences of the University of São Paulo (IAG/ USP) and MARUM, and new project ideas are being discussed in the last months. This time I spent in Bremen allowed me to obtain good results, and provided prime support to my PhD thesis. Moreover, I cannot thank enough the time that received me so kindly and made me comfortable all the time.
