The early-mid Quaternary development of the Bjørnøyrenna Trough Mouth Fan is studied using 3D seismic data. The stratigraphy is divided into three seismic units; unit A (oldest) to C and is correlated to previously established stratigraphic frameworks in the Barents Sea. The reflection configuration and the geometry of the units, in combination with geophysical attribute analysis form the basis for ...

The Hinlopen submarine slide located on the northern Svalbard margin is one of the largest submarine slides documented to date. The cause of the slide is associated with destabilizing factors like glacio-tectonic activity, isostacy, gas accumulation, gas hydrate dynamics, and rapid sediment loading in interglacial periods. Free gas accumulation within continental slope sediments is one of the most ...

This study investigates the spatial relationship between ice-flow direction (inferred from Mega-Scale Glacial Lineations, MSGLs) and subvertical amplitude anomalies in the southwestern Barents Sea. The focus area is in and around the Leirdjupet Fault Complex, a tectonic boundary separating the Bjørnøya Basin from the Fingerdjupet Subbasin. Interpretation of a 3,757 km² 3D seismic cube, complemented ...

Large language models have recently shown the ability to perform complex reasoning and planning tasks far beyond their original training objectives, yet they rarely serve as autonomous building blocks in production systems. Meanwhile, database query optimizers remain rigid, handcrafted systems that struggle with large complex queries. To bridge this gap, we introduce BenderGPT, a pluggable LLM‐powered ...

Deploying machine learning on resource-constrained devices such as microcontrollers, especially in harsh environments (e.g., the arctic) presents significant challenges. This thesis explores solving these challenges in the framework of TinyMLOps, focusing on enabling live model updates and predicting inference latency on STM micro controllers. A method for seamless runtime weight updates via direct ...

This position paper presents a framework for intelligent underwater exploration by marrying foundation models (FMs) with multi‑frequency echosounder data. Echosounder data capture backscattered acoustic signals across a range of frequencies, providing rich insights into underwater environments by exploiting the frequency‑dependent scattering properties of underwater targets. However, their heterogeneity ...

Carbon cycling between surface and mantle reservoirs is pivotal in fostering habitability of Earth. A critical yet poorly constrained parameter is whether crustal carbon can “survive” devolatilization processes that accompany slab subduction and therefore influence deep carbon budgets. Carbonatites provide a key record to address this important topic. Here, we present high-precision potassium isotope ...

Large volcanic eruptions strongly influence the internal variability of the climate system. Reliable estimates of the volcanic eruption response as simulated by climate models are needed to reconstruct past climate variability. Yet, the ability of models to represent the response to both single-eruption events and a combination of eruptions remains uncertain. We use the Community Earth System Model ...

This article presents characteristics of geological and tectonic structures of the Kuljuktau Mountains, mineralogical and geochemical features of its volcanic and intrusive rocks and associated mineralisation of critical elements. The Taskazgan graphite, Shaidaraz lithium, and Tozbulak high-purity quartz deposits, and new prospects for rare earth mineralisation have been identified as the most ...

Foraminifera are important marine environmental indicators widely used in paleoceanography and paleoclimate studies. They are a dominant component of meiobenthic communities around the Antarctic continental shelf, including rarely studied locations below the ice shelves, close to the grounding line. In this study, we use high-throughput sequencing of sedimentary ancient DNA (sedaDNA) targeting ...
