Samuel Pereira

Hei Geo! My name is Samuel Pereira and I have just started my PhD in ‘Hydrothermal Organic Geochemistry’ at the Department for Earth Sciences and K.G. Jebsen Centre for Deep-Sea Research.
I’m from Mumbai (India) and I’ve completed my Bachelor’s degree in Geology (2014-2017) from St Xavier’s College, Mumbai and I also have a Master’s degree in Marine Geosciences (2017-2020) from University of Bremen (Germany). Where I worked with the working groups of Wolfgang Bach and Andrea Koschinsky (MARUM, University of Bremen). My master thesis ‘Geochemical investigations of hydrothermal fluids from the South-Sandwich plate, (Southern Ocean)’ was focussed on fluid geochemistry and thermodynamic modelling in unravelling the formation of magmatic and seawater derived deep-sea hydrothermal fluids.
My aim area of focus has been deep-sea hydrothermal systems, previously I’ve focussed on the inorganics and volatiles in these systems (essentially in the fluids) to understand the formation of these energy-rich fluids, using the chemistry of various species in the fluids (major, minor and trace elements), speciation and solubility calculations, fluid-rock interactions and catabolic thermodynamic models to further understand them in detail.

At UiB has a part of project HyPOD (Hydrothermal Production of Organic molecules: carbon transformation and Decomposition in ocean crust fluids), I’ll be working with Eoghan P. Reeves in understanding the formation of organic molecules in these fluids as a result of pyrolysis of microbial biomass under hydrothermal conditions. High temperature-pressure experiments will be conducted using lab-cultivated biomass (bacteria and archaea) under realistic redox conditions. I’ll be analysing these fluids for hydrocarbons, alcohols, carboxylic acids, amino acids and biomarkers. I’ll also be collaborating with Prof. Ida Helene Steen, Dr Håkon Dahle at Bio, UiB and Dr Florence Schubotz (MARUM, University of Bremen). I’m very excited to continue studying these marvellous deep-sea hydrothermal systems as a part of my PhD and I’m looking forward towards my stay in Bergen! You will find Samuel in room 4140. Welcome to GEO 🙂

Hi! My name is Hannah Petrie, and I have just joined the department to pursue an Equinor-funded PhD in integrated geological characterization of marine ground conditions for offshore wind in the North Sea.
I have a background in Geology and Petroleum Geoscience and have previously studied at the University of Edinburgh (2009-2013) and Imperial College London (2013-2014). After graduating, I moved to Bergen to work as an Exploration Geologist at Statoil/Equinor for four years and also worked as an Operations Geologist for almost two years.
My main area of focus has previously been evaluating hydrocarbon prospects; analyzing large seismic and well datasets within the Northern North Sea region at a range of stratigraphic levels. Most recently I have focused on regional seismic interpretation of Plio-Pleistocene stratigraphy, and I am very excited to continue to study the fascinating glacial geology of the Quaternary of the North Sea as part of my PhD project.

The project is associated with Equinor and with the Bergen Offshore Wind Centre (BOW), which covers a range of innovative offshore wind research projects. I look forward to working with BOW and my supervisors Christian Haug Eide and Haflidi Haflidason on investigating the ways in which a detailed and integrated understanding of the shallow Quaternary subsurface can be used to add value, reduce costs and uncertainties and increase efficiency and cross-disciplinary collaboration in offshore wind installation projects.
Please come by my office in 2G13C anytime if you want to know more about the project, or just to say hi! Welcome to GEO Hannah 🙂

Hei UIBGeo!
My name is Tim Cullen, and I have just started a postdoctoral research fellow position here in UiB working on the Petromaks II DeepRift project. Having visited Bergen a couple of times over the past couple of years for work in PhD in the Syn-Rift Systems project, I am delighted to be coming back and spending more time in the department and the city!
I’m looking forward to seeing plenty of friendly and familiar faces, and getting back into the swing of things here in Bergen.

I am a geologist and have recently finished my PhD at The University of Leeds in the UK, where I was working with Richard Collier, Dave Hodgson and Rob Gawthorpe looking at deep-water and deltaic syn-rift depositional systems in the Corinth Rift. My PhD focussed on understanding how deep-water syn-rift systems respond to the influence of structural and climatic variability. I’m going to be carrying on thinking about this and some others things and seeing if we can apply our work from the Corinth Rift in the previous syn-rift systems project to the Norwegian Continental shelf.
You’ll be able to find me in office no. 2101 once I’m in the department so feel free to pop by! Welcome back Tim 🙂

Karl Purcell

Hello everyone, My name is Karl Purcell. I just started a PhD this June under the supervision of Margit Hildegard Simon and Eystein Jansen at the GEO department and the SapienCE centre. I will be working on reconstructing late Pleistocene paleoenvironments in South Africa by analysing marine sediments (e.g.: XRF, plant wax isotopes, OSL, …) and climate model data to help relate climatic reconstructions with early human behavior.

I am currently in Gatineau (Canada), my arrival being delayed due to the corona pandemic. I was born here in Gatineau, and I completed a Bachelor’s degree in metallurgical engineering and later a microprogram on climate change at Laval University, in Quebec City. I moved to Montreal and worked as a metallurgical lab technician between 2014 and 2017 before finally getting back to school for my master’s degree in Earth sciences at the Université du Québec à Montréal. My MSc project was a study on the use of 230Th excesses to constrain the ages of late quaternary sediments in the central Arctic Ocean. During the master I loved the idea of helping to elucidate our past, and I know this new project for my PhD will fuel this passion.

Aside from work, I love the outdoors and I genuinely enjoy rainy days so Bergen should be great. I also practice parkour/freerunning, lifting, running and rock-climbing. I will definitely hike around a lot, and maybe even go surfing on the coast.

Looking forward to meet you all! Hopefully you will soon find Karl at Jahne Bakken 5. Welcome to GEO 🙂

Hakan Heggernes

Hi everyone! My name is Hakan and I started my PhD in structural geology in the middle of April, just after Easter. Professor Atle Rotevatn is my supervisor. I am from Bergen and I have pretty much done my entire education at UiB, with the exception of an exchange semester at Utrecht University in the Netherlands. I finished my bachelor’s degree in 2017, and I finished my master’s degrees in sedimentology and structural geology in June 2019.

At UiB I will be part of the Basin and Reservoir Studies group. During my PhD project I will investigate structural and stratigraphic controls on fluid flow in a range of sandstones. The main focus will be on poroperm properties, network properties and the distribution of sub-seismic structures like deformation bands and faults. The work will include core analysis from the Ivar Aasen field in the North Sea, and outcrop analysis from fieldwork, which will work as analogues to subsurface reservoirs.

When we get back to UiB, which hopefully is soon, you can find me in office 2152A. Velkommen til GEO 🙂

Marie Eide Lien

Hi everyone!
My name is Marie, and just recently I started my 4-year PhD project with Thibaut Barreyre as my supervisor, and I will work with sub-surface fluid flow dynamics in hydrothermal systems. The project’s aim is to unravel the complex mechanisms that affect fluid flow in the sub-surface of these systems through observation, data analysis, and modelling. Further details of the project is a work-in-progress still.

I acquired both my bachelor and master degrees at UiB, so I am happy to be back!  During my master I had the pleasure of working with Asc. Prof Henk Keers on my geophysics MSc project titled “Analysis of Magma Chamber Activity at Yellowstone from 2010 to 2017”. The aim was to explain the observed surface deformation and associated seismicity using  seismic tomography models and inverted deformation data for volume changes in the underlying magma chamber. I also spent time researching the Yellowstone hydrothermal system and its possible relation to the seismicity and deformation.

I graduated from UiB in 2017. I then left Bergen to work as a high school teacher through a program, which aim is to motivate students in all social classes for STEM. As a part of the program I also obtained a teaching degree at the University of Oslo. During the summer of 2019 I moved back to Bergen and interning at Equinor in petroleum technology, a chance to also gain more experience in seismic and structural interpretation, production and field development.

Although I am in my home-office, glancing at RFB through my window, it’s great to be back at GEO. I look forward to see both well-known and new faces when we’re all back on campus. At Campus you will find Marie in room 3153a. Welcome to Geo 🙂

Johanna Marquardt – new employee at GEO

Hi everyone, My name is Johanna and I just started my PhD at the UiB with Nele Meckler! So far, I can only join you virtually via home-office from Germany due to the current Corona situation, but I hope that I will be able to physically meet you soon. My PhD project aims to reconstruct ocean temperatures during past episodes of greenhouse climate in the Cenozoic, and potentially also during major Cenozoic climate transitions. Thereby, at least a part of the project will focus on the early Eocene warm period ~50 Myrs ago. I will use clumped isotope paleothermometry on foraminifera (marine calcareous microfossils) and I would like to compare the resulting data with results of other paleotemperature proxies as well as climate model output.

For the last 2 years, I worked as a lab technician for the SWEET project (Super-Warm Early Eocene Temperatures and climate) with Phil Sexton at the Open University, UK. This project aims to reconstruct climate conditions during the extreme greenhouse warmth of the early Eocene. Besides maintenance of the microscope laboratory, my role in this project was to process deep-sea sediment samples and to pick multiple species of planktic and benthic foraminifera and fish teeth for C, O, B and Nd isotope analyses. The resulting data will form the basis for reconstructions of past ocean pH and atmospheric CO2 concentrations during the early Eocene, as well as complementary reconstructions of ocean circulation and temperatures.

I obtained my BSc in geosciences and my MSc in marine geosciences at the University of Bremen, Germany, with the focus on marine environmental archives, climate change and marine sedimentology. For my Master’s Thesis, I used O and C isotope analyses of foraminifera to reconstruct the late Quaternary evolution of intermediate water masses off Newfoundland under the supervision of Stefan Mulitza and Rüdiger Stein and investigated how surface freshwater input affected the intermediate water mass formation.

I already studied at the UiB several years ago during my Bachelor programme, and I am excited to join you again and to finally learn Norwegian! You will find (hopefully soon) Johanna in room 3153B Welcome to GEO Johanna 🙂

Andreas Beinlich

Hi Geo! I joined the department on February 1st and will contribute to research and education in Petrology and Mineral Resources with a focus on fluid-rock interactions. I am German and have a Diplom in Geology from the University of Würzburg and a Postgraduate Diploma in Science/Geology from the University of Otago, New Zealand. For my PhD at the University of Oslo I was working on ultramafic rock carbonation in systems spanning surface weathering to mid-crustal hydrothermal. Subsequently, I did a 3-year postdoc at The University of British Columbia (Vancouver, Canada), where I joined the Mineral Deposit Research Unit as project coordinator of the Carbonate Alteration Footprint (CAF) project. For the CAF project we further developed the application of stable oxygen and carbon isotopes as an exploration tool for carbonate-hosted hydrothermal ore deposits. For my second postdoc I joined The Institute for Geoscience Research (TIGeR) at Curtin University in Perth, Australia. There, I continued to work on fluid-solid/rock interaction processes with a wide range of applications from purely scientific to applied using an integrated approach of field observations, experiments in the laboratory, and theoretical modeling. Some of the key topics are the timescale of hydrothermal reaction front propagation, ophiolite carbonation (ICDP OmanDP), coupled mineral replacement reactions and mass transport in sulfide-bearing ultramafic systems, the interplay between deformation, fluid flow and alteration, and experimental investigation of Li and Cu extraction by fluid-driven solid-solid replacement reactions.

At UiB Geo I am going to continue my cross-disciplinary research approach to better understand active ocean floor alteration and mineralization by integrating shipboard/field work with extended experimental capabilities and analysis. My current research and active interests are the geological carbon cycle and the efficiency (or lack thereof) of carbon transport into the Earth’s mantle, the geophysical footprint of pervasive hydrothermal alteration, fluid flow through the crust in general, ore mineral tenor upgrade and metal liberation through fluid-solid interaction, and the feedbacks between concomitantly occurring mineral replacement reactions.

I am looking forward to chatting and collaborating with as many of you as I can. Thanks for having me! You find Andreas in room 4104 – Welcome to GEO 🙂

Hi, I have recently started in an adjunct position through the Akademia Agreement. My background is also from UiB, where I took my Master and PhD. Since 2012 I have worked in Statoil/Equinor with international exploration and this position has allowed me to do regional work in most continents of the world. Approximately one year ago I moved into the research department where I currently work in the sedimentology and stratigraphy group. My daily work now involves regional studies in South America and the North Atlantic, where we are undertaking tectonostratigraphic analysis of the margins and basins. This work also includes following up and integrating external academic projects and results that are relevant for our regional understanding.

My main research interest is to study recent (Quaternary) and ancient (Mesozoic) erosional-depositional systems to better understand and quantify how they respond to tectonic and climatic perturbations. The North Atlantic continental margin is one of the areas where this can be investigated at various levels and represents a key study area for further work. This type of analysis required interdisciplinary collaboration and integration of stratigraphy, thermochronology, geodynamics and structural geology. The goal is to make integrated models that can better predict and capture the stratigraphic variability that is present along this and other continental margins.

My daily work place is in Oslo but I visit Bergen frequently. Don’t hesitate to send me an email if you have something you want to discuss! Welcome back Tor 🙂
