Sedimentary Environments 2022-23
Ysgol Gwyddorau Eigion
Modiwl - Semester 2
This module takes a catchment to marine basin approach, focusing on riverine, coastal and deep marine environments. The module will provide a foundation and conceptual framework in which to understand river and marine systems, environmental change and geochronologies. Response to climate change, human activity, tectonics and base-level change during the Quaternary will be explored, along with developing an understanding of both intrinsic and extrinsic processes operating within these different but connected environments. The module will examine sediments within these environments, which are important components of key dynamic, biogeochemical and ecological systems, and have major socio-economic significance. This module examines the origin, controls, and processes that determine the properties, transport and deposition of sediments in rivers, shallow water environments (e.g. beaches, barriers, deltas, tidal flats), continental shelf and slope environments, and the deep ocean basins. The module will take both an applied and scholarly approach to the subject, introducing the students to the current debates and literature in the field.

- Critically analyse the literature.
- Demonstrate knowledge of the key concepts governing fluvial behaviour in a catchment.
- Explain the features of ancient and modern braided and meandering river systems and sedimentary sequences.
- Make field observations to reconstruct ancient sedimentary environments (ES 184.108.40.206)
- Synthesise and summarise interdisciplinary information critically (ES 220.127.116.11)
- Understand how an interdisciplinary approach is needed to understand the nature of sediment deposits (ES 18.104.22.168)
- Understand physical and key biological controls of sedimentation in coastal and shelf seas, and deep sea environments, and the temporal and spatial scales of variation, and anthropogenic impacts (ES 22.214.171.124)
- Understand the concepts and principles which govern marine sedimentary environments (ES 126.96.36.199)
- Understand the controls operating within fluvial systems and be able to comprehensively discuss how these condition river response to environmental change.
- Understand the long-term dynamics of river systems.
Exam (Centrally Scheduled)
PGT level task Students are given an previously unseen task to solve over a limited time period (48h). It's mimicing a professional workplace where students get a limited time to solve a sediments-related problem and to report on it.
