DC10: Characterization of lithology endmembers – bridging the gap between micro-scale sediment characteristic and macro-scale landslide behaviour

Doctoral Candidate

Dina Hanifah

I am Dina Hanifah, a Marine Geologist originally from Indonesia. With every dive into professional experiences through interdisciplinary research and collaboration, my expertise spans geology and marine science, with a focus on sedimentology, marine geology, and oceanography. Growing up in the world’s largest archipelago—surrounded by two vast oceans and situated along the Pacific Ring of Fire— I developed a deep-seated passion for understanding marine geohazards and their impacts on coastal regions and critical offshore infrastructure. This journey began with a Bachelor’s degree in Geological Engineering from Jenderal Soedirman University, Indonesia, where I built a strong foundation in earth sciences. My passion has since taken me across the globe, where I earned a dual Master’s degree—Master of Science in Marine and Lacustrine Geosciences from Vrije Universiteit Brussel-Universiteit Gent-Universiteit Antwerpen in Belgium, supported by the prestigious VLIR-UOS scholarship; and Master of Engineering Geology from The University of Auckland, New Zealand, fully funded by the Manaaki New Zealand Scholarship.

My professional experiences have provided me with a global outlook and the opportunity to hone advanced skills in sediment coring and analysis, underwater mapping and sampling, and using cutting-edge tools for offshore exploration and oceanographic data processing, including GIS. I have participated in transformative international collaborations, such as the “Geologic Champagne” subproject in New Zealand, where I investigated the interplay between seafloor morphology and ocean currents as part of a wider effort to understand CO2 release mechanisms from the subducted Hikurangi Plateau. Recently, I served as an at-sea marine geologist during a West Pacific Ocean expedition with the International Seabed Authority (ISA), in collaboration with KIOST and Ministry of Oceans and Fisheries, Republic of Korea, focusing on cobalt-rich ferromanganese crusts. Beyond these projects, I have been actively engaging in global IODP-related initiatives, associated with ANZIC and ECORD, enhancing my technical expertise and expanding my collaborative global network.

Starting December 2024, I am excited to embark on my PhD journey as part of the POSEIDON project at MARUM, University of Bremen, under the DC10 framework of the Marie Skłodowska-Curie Actions programme. My research focuses on the characterisation and role of sediment lithology in submarine landslide behaviour, bridging micro-scale sediment characteristics with macro-scale geohazard processes. By integrating geophysical methods, sedimentological analyses, and geotechnical experiments, my work aims to contribute to enhancing offshore infrastructure resilience against climate-driven challenges. With a commitment to drawing on my global experiences and interdisciplinary expertise, I look forward to advancing our understanding of marine geohazards and contributing to a safer and more sustainable future.

Submarine landslides are gravity-driven mass movements occurring in underwater slope settings worldwide and represent a significant marine geohazard, posing risks to coastal regions and critical offshore infrastructure. While mapping efforts have advanced, there is a lack of detailed understanding of the internal structure, composition, and failure planes of submarine landslides, which are essential for linking landslide behaviour to sediment lithology. This project focuses on investigating how sediment lithology influences submarine landslide formation, kinematics, and emplacement behaviour. By combining geophysical methods, core-logging, sedimentological analyses, and geotechnical experiments, the research aims to bridge the gap between micro-scale sediment characteristics and macro-scale geohazard processes, contributing to improved risk assessments and enhanced resilience of offshore infrastructure.

Specific Objectives:

  1. Characterise sediment lithology endmembers using geophysical, sedimentological, and core-logging techniques to identify key properties influencing landslide dynamics.
  2. Analyse the kinematics and emplacement behaviour of submarine landslides through geotechnical experiments and advanced modelling.
  3. Develop an integrated framework connecting micro-scale sediment properties to macro-scale landslide processes to improve understanding and hazard mitigation strategies.

 

Expected Results:

  1. Improved understanding of the relationships between sediment lithology and submarine landslide mechanisms.
  2. Advanced methodologies for linking micro-scale sediment properties to macro-scale geohazard processes.
  3. Enhanced frameworks for assessing risks and improving resilience of offshore infrastructure against climate-driven challenges.
