Description
This studentship has two related projects.
Project A: the development of a Climate Generator: A Bayesian stochastic emulator of expensive General circulation climate models. This project will explore different approaches to emulating the response of computationally expensive climate models for glacial cycle ice sheet modelling contexts.
Project B: Building on the discussion in
https://www.physics.mun.ca/~lev/revCalG.pdf, this project will compare different stochastic process and Bayesian artificial neural network emulators for history matching contexts and refine methodologies for history matching in paleo ice and climate modelling contexts.

Description
This studentship has two related projects:
Project 1A: History matching (cf https://www.physics.mun.ca/~lev/revCalG.pdf) of a global coupled ice and climate model for the last glacial cycle. From Last Glacial Maximum onward, glacial geology and relative sea level data provide a strong set of constraints which are a challenge to fit. Conversely, prior to LGM, there are much fewer constraints on ice sheet evolution aside from far-field sea level proxies. However there are many more constraints on regional climate from ice core, terrestrial, and marine core records. This history matching will therefore focus on pre-LGM global ice sheet and climate evolution relying more on paleoclimate constraints.
Project 1B: Using the history-matched parameter vectors from project 1A, examine the stability of select glacial cycles of the last 2 million years especially in the context of explaining the mid-Pleistocene transition from approximately 40 kyr glacial cycles to 100 kyr cycles. This will entail analysis of noise sensitivity (eg from large volcanic events), the impact of changing topography due to subglacial erosion and sediment transport, and the testing of simplified carbon cycle representations. These projects will rely on a hierarchy of coupled ice and climate models including the LCice2.0 coupled glacial system model (GSM) and LOVECLIM EMIC (an earlier version was detailed in Bahadory and Tarasov, GMD, 2018, Bahadory et al, CP 2021) as well as a new version coupled to the Plasim GCM (Andres and Tarasov, CP 2019). A key relevant feature of LCice is the state-of-the-art fully coupled sub-glacial sediment processes model in the GSM (cf Drew and Tarasov, https://egusphere.copernicus.org/preprints/2024/egusphere-2024-620/)
