Searching for lacustrine tsunami deposits with the aid of a numerical model
Christopher Campbell Di Paolo
A Mw ca. 5.9 earthquake occurred in 1601 CE in central Switzerland which triggered multiple subaqueous and subaerial landslides in and around Lake Lucerne. One of these subaqueous landslides triggered a tsunami which hit the city of Lucerne. While this tsunami was documented historically, physical evidence remains sparse. Using the numerical modeling software BASEMENT, we simulated the tsunami’s sediment transport. With this model as a guide, we then took 9 sediment cores in areas of interest. We link an event layer which exists in 4 of the 9 cores to the 1601 CE event. The program BASEMENT proved to be effective at simulating lacustrine tsunami sediment transport.

Deep transfer learning for mapping rare Arctic oil seeps observed from satellites
Julien Vadnais – Department of Earth Science, UiB

Abstract
Natural seepage is a significant contributor to marine oil inputs. Remote and intermittent seeps are difficult to monitor in the field, yet oil slicks can be observed by spaceborne synthetic aperture radar (SAR) because they reduce backscatter, creating potential for automatic mapping. In mapping tasks like segmentation, deep learning models excel, albeit needing large amounts of labeled images. To deal with scarcity of labeled images, transfer learning is an approach commonly used in computer vision, though still underutilized in remote sensing.
Different Sentinel-1 acquisition modes, in the Arctic compared to elsewhere, complicate direct model transfer for oil slick mapping. Here, we present a use-case where transfer learning enhances the segmentation of natural oil slicks, most notably in challenging and noisy images. Our method proves efficient even with limited training images, offering new prospects for studying poorly understood or yet undiscovered hydrocarbon seeps.

Ridge to reef volcanic hydrogeology: submarine groundwater in the world’s most biodiverse coasts
Bayani Cardenas – Jackson School of Geosciences, The University of Texas at Austin

Abstract
Water flows from land to the ocean not only through rivers and estuaries but also below-ground through coastal and submarine aquifers. While the global fresh submarine groundwater discharge (SGD) is less than nutrient inputs are 25% of riverine inputs. This land-ocean connectivity is important for sensitive ecosystems such as coral reefs if the groundwater we present the interesting but in the Philippines which has been coral reefs provide for local communities. We studied coastal and submarine thermal springs associated with high fluxes of acidic waters and carbon dioxide, some of which are within or close to thriving coral reefs. The SGD fluxes are amongst the largest in the world and the SGD carbon dioxide fluxes overwhelm coastal carbon budgets. The presentation delivers explanations for the high SGD, discussing the mechanics and different sources and pathways of water, by bringing together multiple lines of evidence from different methods including deep diving, drones, novel sensors, geochemical tracers, thermal remote sensing, and modeling.
