Unearthing a link between old and new plate boundaries and present-day seismotectonics of Svalbard: First insights from the new high-res 700k earthquake catalog of the European plate’s far North
Abstract:
Oceanic ridges and transform faults comprise nearly 45% of the Earth’s plate boundaries. Even though they have lower seismic moment release rates than convergent plate boundaries, these intricately segmented oceanic plate boundaries host a large part of Earth’s seismicity. Analyzing how their segmentation is expressed through their seismic behavior has not been commonly possible due to limited observations compared to plate boundaries on land. This knowledge gap has also hampered efforts to understand the causes of seismicity in regions adjacent to the plate boundaries, such as the Svalbard archipelago. A challenge for these remote areas is that there is often no overlap between event catalogs produced routinely from regional networks (typically with M>3.5) or from short local deployments (M<3). To close this gap, we apply a sensitive earthquake detection pipeline to complement a regional catalog over 25 years through HPC-supported template matching. We focus on the 3000 km of oceanic plate boundaries and adjacent areas in the European Arctic (68° – 87°N, 20°W – 40°E). From an initial dataset of 35k earthquakes, we obtain a new catalog of 700k events, including 150k events with high-resolution relative locations and ~80k glacial events. In this talk, I present this new data product with a focus on four areas where our analysis has unearthed completely new faults and seismicity patterns: (i) the amagmatically rifting Lena trough, (ii) the ultraslow-spreading Mohn and Knipovich ridges, (iii) the transform fault-bound Molloy deep, (iv) and the transtensional fault arrays of Nordaustlandet and Spitsbergen. We correlate the latter fault patterns with former plate-bounding thrust faults of the Timanian orogeny and compare the seismicity patterns with those found in transtensional settings along the San Andreas fault. Since this catalog contains far more new seismicity features than one can analyze alone, we invite everyone to explore this unique data product and to discuss new findings in the light of geodynamics and plate tectonics, field and structural geology, ridge tectonics and volcanism, and other phenomena such as methane seeps and glacial activity on Svalbard.

Where do they come from? Where do they go? Diamonds in Namibia
An indoor fieldtrip to Southern Namibia
by Lucas Valore and Melanie Kling
This May, Lucas and Melanie have had the opportunity to participate in a source-to-sink fieldtrip to Namibia as part of their training. There they saw and discussed where the source of the diamonds is, how and when they have been transported, and where they were finally deposited. During the fieldtrip they investigated locations in the Namibian desert and even the restricted government-controlled area, the Sperrgebiet, where the diamonds are currently mined.
This Wednesday they present some MARVELOUS photos from the fieldtrip and speak about the story of the diamonds. An important objective of source-to-sink studies is to disentangle overlapping forcing parameters and their individual impacts for stratigraphic and paleogeographic evolution. Therefore, they will also discuss a potential tectonic or climatic control behind the transport and deposition of the diamonds. Additionally, they promise
big outcrops due to minimal vegetation,
occasional antelopes and a story involving jackals,
spy-pictures from the diamond mines, and
insights on how the diamonds are mined.”

The Hunt for Water: glacier hydrology on Svalbard
My name is Andreas and my research focus is within glacier hydrology with an interdisciplinary approach. Originally from Germany, I did my masters in mechanical engineering in Germany and at UNIS working on thermodynamical FEM glacier modelling. Afterwards I did my PhD at the Department of Geosciences at the University of Oslo about glacier channel hydrology on Svalbard, as a combination of field-based observations (summertime surface work and speleological investigations in wintertime) and the development of drifter technology. As I finished my PhD early, I could spend the last year of my contract in Oslo, building up several field-based projects on Svalbard, investigating marine ecosystem and glacier dynamic impacts of a glacier lake outburst flood, the rapid disintegration of a tidewater glacier tongue based on bathymetric data and ice-ocean interactions at Austfonna.
During the past year, I worked part-time at the Centre of Biorobotics at Tallinn University of Technology, continuing the work on my own projects and working on several proposals to increase monitoring capabilities at ice-ocean interfaces.
I have just joined UiB as an outgoing SEAS Postdoctoral Fellow to work on nutrient transport by buoyant meltwater plumes to fjord ecosystems in Greenland. This work will be part of the Climate Narratives project with Kerim. The outgoing phase will be one year at the Scripps Institute of Oceanography in California and one year in Greenland.
Besides my scientific work, I’m heavily involved in scientific outreach and guiding in both the Arctic and Antarctica. Especially my work as expedition leader of small expedition vessels (e.g. National Geographic) has given me access to and insights into some of the remotest places in the polar regions. You can find Andreas in his office on the second floor.

Tlateles, gardens, chinampas and swamps. The Basin of Mexico more than a lacustrine landscape
Kurt Henrich Wogau Chong
The endorheic Basin of Mexico (BM) is characterized by a heterogeneous landscape that comprises volcanic and tectonic structures and a diversity of depositional systems that include glacial, alluvial, fluvial, eolian, and lacustrine sediments. The alluvial plains around Lake Texcoco are complex features formed by medium to low-order fluvial drainages. Additionally, the structure of these plains is complicated by the influence of springs and wetlands, many of which are associated with archaeological sites of various periods. The proposed work aims to study the landscape evolution of floodplain areas in tandem with human occupations spanning the preceramic, agricultural, and Aztec periods on the eastern side of Lake Texcoco. A paleo landscape reconstruction will be performed using the floodplain sediments of San Bernardino and Chapingo fluvial systems as natural archives and the archeological record from the Texcoco Man pre-ceramic burial site.

Coseismic Ground Failures of 2020 Petrinja Earthquake & Plans for PhD adventure
Nina Hećej
At the upcoming Geolunch event, I will introduce myself through a two-part presentation. Within the first part, I will discuss prior research on coseismic ground failures that followed the 2020 Petrinja earthquake in Croatia. While I’ll cover all observed processes, I’ll primarily focus on sand boils, lateral spreading, subsidence (resulting from liquefaction), gravitational movements on slopes, and the sudden emergence of numerous collapse sinkholes. This will be followed by a brief overview of my PhD research proposal, highlighting the intended data and methodologies. I am looking forward to holding the presentation, and even more to your questions and comments, especially for the latter part.

Wojtek Nemec Memorial Geolunch programme
This geolunch hosts a session dedicated to former GEO Professor, Wojtek Nemec, who sadly passed away last month. Wojtek arrived at UiB in 1984 and became a full professor in 1993 where he supervised more than 50 MSc and 20 PhD candidates to the competition of their degrees until his retirement in 2017. Alongside this he maintained outstanding research work making him an internationally renowned sedimentologist focussed on mass flows, slope process and conglomerates. After hearing the news of Wojtek’s passing, Flavio approached us with the excellent idea to host a memorial seminar hosting some former colleagues of Wojtek. The session will contain a short video interview with Ron Steel, former NorskHydro researcher, UiB professor and now Emeritus at UT Austin who hired Wojtek, some words from colleagues at UiB (William Helland-Hansen and Atle Rotevatn) followed by some short talks of memories from some of Wojtek’s former colleagues (Sergio Longhitano, Massimiliano Ghinassi and Katarina Gobo).

Basin evolution of the Central South Atlantic wide rifted margins, insights from 2-D geodynamic modelling
Thomas Theunissen
The thick late syn- to early post-rift shallow water evaporites in the most distal part of wide rifted margin is paradoxical with the deep depression at crustal breakup time predicted by isostatically compensated lithospheric thinning models.
Elevation of the distal margin and water depth during deposition of the late syn-rift evaporites and early post-rift carbonates in the central South Atlantic are not well constrained and remain to be quantified.
We use forward 2-D thermo-mechanical modelling coupled with melt prediction and surface processes to assess the contribution of lithospheric and mantle processes on the distal margin topography and subsidence history during continental rifting.
Model results show that (1) counter-flow of depleted lower lithospheric mantle during rifting explains the magma-poor nature of these margins and (2) weak crust and syn-rift sediment control the crustal necking width and subsidence history of the distal margin.
Thin syn-rift sediments (~2 km) result in a deep air-loaded (-2000 +/- 200 m below global sea level (bsl)) distal margin while thick syn-rift sediments (~ 6 km) result in a shallower (-500 +/- 150 m bsl) elevation.
Integration of our modelling results with quantified geophysical and geological observations suggests that (1) base level was down to -600 m bsl during distal margin formation in the Aptian before sag and evaporite deposition, (2) base level was about -300/-400 m bsl at the end of evaporite deposition, and (3) scenarios with a fixed shallow base level (-400 m bsl) and with an increasing base level from an initially deep position (-1600 m bsl) during evaporite deposition can both fit the observed evaporite distribution.
However, erosional features along the base of evaporites suggest a deep initial base level.

Insights into deformation band networks: Spatial variability in topology, connectivity and permeability
Hakan Heggernes
I will give a talk on my first PhD-paper, which was recently published. In this paper we characterize networks of deformation bands from an amazing outcrop close to the San Rafael Swell in Southeastern Utah. Here we use topology to assess deformation band intensity, network connectivity and effective permeability of deformation band networks. We also explore the spatial variability of such networks, and how these properties might affect a subsurface reservoir. See you on Wednesday!
Paper abstract:
Networks of deformation bands have the potential to act as baffles to fluid flow, yet little work has been devoted to addressing their network properties, such as topology and connectivity. Motivated by this, we investigate the two-dimensional spatial variability of areal intensity, node and branch topology, and network connectivity within select deformation band networks in the Jurassic Entrada Sandstone (Utah). The results highlight distinct topological signatures for deformation band networks, dominated by Y-nodes, and IC- and CC-branches. Low proportion of isolated II-branches reflects the evolution of deformation bands through bifurcation and abutment (Y-nodes) to form interconnected networks. A key observation is that network connectivity and topology exhibit great spatial variability within one and the same deformation band network. We evaluate effective permeabilities across the deformation band network, incorporating a topological measure of network connectivity into the permeability calculations. Results highlight that deformation band networks with >1.5 connections per branch can significantly reduce effective permeabilities, whereas networks with low connectivity may offer pathways for tortuous fluid flow.

The History and Evolution of Marine Geophysics at GEO: from 1960 to present
Rolf Mjelde
This contribution primarily presents the development of Solid Earth land and marine geophysics at the University of Bergen from 1960 until the present. A large number of projects employing controlled seismic sources have been conducted, and some of these were important for the development of plate tectonics from hypothesis to scientific theory. The most important project conducted was the Continental Shelf Project (1961-1981), with yearly acquisition of marine multi-channel seismic data along the entire Norwegian continental shelf and southern Barents Sea. That project was motivated by earlier smaller projects that documented thick sedimentary sequences off the Møre coast and in the Skagerrak. This combined mapping and basic research work provided the foundation for Norway as an oil-and-gas nation. The contribution to society from the marine geophysical environment at the University of Bergen has not only been their own research, but equally much the geophysical education they have provided for their students. The most successful among these have created tens of thousands of jobs through the development of e.g. 3D, 4D and 4C seismic. The instrumentation and methods developed with contribution from the University of Bergen have not only relevance within exploration and production of hydrocarbons, but also for the green transition, e.g. within storage of CO2, mineral exploration and seafloor stability evaluation for installation of windmills offshore. The same seismic methods are extensively used within climate research.

Morphodynamic Foundations of Coastal Sumer
Liviu Giosan
The world’s first cities and states, in their modern definition, developed from 6000 to 5000 years ago in Mesopotamia near the coast of the Persian Gulf, on the combined delta of Tigris and Euphrates. Despite more than 200 years of research their emergence remains enigmatic. Here I discuss the environmental context for coastal Sumer based on recent drilling-based work in Iraq and propose a new morphodynamic theory for urbanization.

Deformation and slip localization in porous volcaniclastic rocks: tuff adventures in eastern Taiwan
Atle Rotevatn
Taiwan features some of the highest uplift rates, and highest erosion rates in the world. With that comes growing mountains, rapidly incising river gorges, highly active surface processes and related geohazads, all of which makes this a very interesting place to any geoscientist. Eastern Taiwan also features an accreted island arc complex, where volcanism that occurred approximately 5 million years ago has produced an absolutely awesome succession of volcaniclastic deposits knowns as the Shihtiping Tuffs. This succession has been deformed at relatively shallow burial depth during ongoing plate convergence, and between 2015 and 2017 I had the pleasure of spending three field seasons with students from UiB and colleagues from the University of Bordeaux and the National Taiwan University in that area. In the years that have followed, more people have become involved, and in this talk I will talk about the deformation features we see in the Shihtiping Tuffs, and what they can teach us about deformation mechanisms and controls on slip localization in such rocks.

The Enigmatic Mackenzie Mountains
Prof Derek Schutt, from Colorado State University
Global-scale seismic velocity models of the Northern Canadian Cordillera show high velocities to the east of the Cordilleran deformation front and low velocities to the west. This velocity contrast is consistent with other geophysical observables, such as regional seismological studies, that indicate a weak and thin lithosphere to the west that transitions quickly to a strong and thick craton-like lithosphere at the deformation front. We present new results using data collected by the Mackenzie Mountains EarthScope Project, which included an ~875 km-long line of 40 broadband seismographs across the Cordillera and into the craton extending from roughly Skagway, Alaska to Great Bear Lake, Northwest Territories. The 3-year overlap of this deployment with other broadband seismic stations in the region, most notably the EarthScope Transportable Array and the Yukon Northwest Seismic Network, allows for detailed imaging of the upper lithosphere. Results show large velocity variations west of the deformation front. Notably, we image a 5% Vs low that extends from the upper crust to the asthenospheric mantle. This plume-like structure, and associated weakening, may be a primary cause for the ongoing uplift of the Mackenzie Mountains at their unusually eastward location. We also image a low velocity feature in the lower crust extending to the west of the deformation front, which may facilitate eastward crustal translation along a large-scale (~800 km) decollement system driven by the Yakutat indentor consistent with the orogenic float hypothesis of Mazzotti and Hyndman (2002). We note strong lithosphere-scale lateral heterogeneity suggesting that 3-D effects are important in focusing deformation in the Mackenzie Mountain area.

A thirsty fault: prolonged fluid flow along the Helmsdale Fault
Matteo Demurtas
Within syn-rift basins, the juxtaposition of rift-related clastic deposits in the hanging wall of basin-bounding normal faults against crystalline basement is a recurrent structural setting where plays can be found. Here, fault-controlled fluid flow can exert a major role on fluid pathways by means of mineralization and cementation of the host rock.
The Helmsdale Fault in NE Scotland is an excellent exhumed example of a syn-rift basin bounding fault, where timing and paragenesis of fluid flow can be studies in details. The Helmsdale Fault bounds the western side of the Inner Moray Firth Basin in NE Scotland, which developed during rifting in the Late Jurassic. The hanging wall of the Helmsdale Fault consists of Late Jurassic Helmsdale Boulder Beds that are made of alternating debris flow to fault scarp deposits, whereas the footwall is composed of the Helmsdale Granite (Silurian-Devonian in age). Significant fluid flow along the Helmsdale Fault is testified by widespread calcite veining, locally making up to 5 m thick fault cores of stacked veins. A complete suite of microanalysis including optical microscopy, clumped isotope, geochronological analysis as well as fluid inclusion analysis suggests a high variability in time and space of fault-controlled fluid flow, and possibly a more complex deformation history than what previously though.

Taking a Closer Look at Mass-transport complexes (MTCs): Their Dynamics and Architecture
Harya Nugraha
Mass-transport complexes (MTCs) are common features in deep-marine environments. Their emplacement can catastrophically displace sediment to continental slope and basin floor, and have a direct impact on society by generating tsunamis and destroying offshore infrastructure. The proliferation of high-resolution multibeam bathymetry and three-dimensional seismic reflection data have improved our understanding of their internal form and emplacement processes. However, uncertainties remain in terms of: (i) how the volume and flow behaviour of MTCs evolve during their translation, and what controls these changes; (ii) how strain is distributed within MTCs, and its relationship to their internal architecture and geometry; and (iii) what are the implications of MTC emplacement processes for geohazard risk and petroleum system assessments in sedimentary basins. To address these problems,three-dimensional seismic reflection, well, and bathymetry data from the Exmouth Plateau (offshore NW Australia) and the Makassar Strait (offshore Indonesia) are used. This study demonstrates that: (i) dynamic interaction between mass flows and substrate lead to the final volume is three times the initially evacuated volume on average, and the formation of intra-MTC flow cells that can translate with a different speed and runout distance; (ii) strain distribution of an MTC is variable along strike, resulting in the variations of internal architecture and frontal geometry, partly controlled by the basal shear surface depth and morphology; and (iii) changes in MTCs volume and flow behaviour should be considered for tsunami and impact modelling, and heterogeneity of MTCs should be characterised when evaluating their reservoir and seal potential for hydrocarbon systems.

Modelling and inversion of electromagnetic induction log using the Integral Equation method
Durra Handri Saputera
Electromagnetic (EM) induction logging tools are commonly used to assist the optimal trajectory decision process while drilling. The tool typically has multiple axial components with different sensitivities to the subsurface structure and anisotropy. Three-dimensional (3D) inversion of induction logs enables imaging of complex geological formations. However, it is still very challenging because of the significant computational cost of the 3D forward modelling. This motivates the study of inexpensive approaches to the forward and inverse problems. In this talk, I will give an overview of the things we have developed based on the implementation of the Integral Equation method on the forward and inverse problems.”

Baffled by Baffles: Modelling and Evaluating the Effects of Internal Heterogeneity in Wave-dominated, Shallow-marine Reservoirs
Agustin Argüello Scotti
Shallow marine successions make for excellent oil and gas reservoirs worldwide and are particularly important as carbon capture and storage targets. Although usually very noble reservoirs, their internal heterogeneities can have a significant impact on fluid flow under certain conditions. Even so, there are not many available efficient methods to model such heterogeneities. The general aim of this talk is to show how baffles or barriers in shallow-marine wave-dominated reservoirs can be modelled by the GEOPARD algorithm, allowing for the evaluation of their effects on fluid flow using the Eclipse 100 simulator. This is achieved by (i) modeling an outcropping shallow marine succession with Truncated Gaussian Simulation and GEOPARD, showing the differences between the traditional and the newly developed method, (ii) showing how to set up an experimental design in ECLIPSE, designed to evaluate the effect of geological heterogeneity in fluid flow and (iii) comparing the impact of modelling and not modelling heterogeneities; helping us realize if it’s worthwhile to be ‘baffled by baffles’.
