PhD position in Digital Ice-Cores; Paleo-Climate reconstruction using Bayesian modeling

Bremen, Germany
Category
Logistics
At the Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung, AWI (awi.de) offering a fully funded PhD position on ice-core based climate reconstructions.

Searching for candidates from math/ computer sciences or physics who are interested in advancing temperature reconstructions from ice-cores using Bayesian modeling.

In the framework of the MARDATA graduate program (https://www.mardata.de), the position will be jointly supervised by an expert in computer science/numeric/inference (Prof. Peter Zaspel, Jacobs University Bremen) and an expert in climate/ice-core sciences (Prof. Thomas Laepple, AWI).
Description
To understand future climate change, it is critical to fully understand the past and present climate system. Information about this is encrypted in paleoclimate archives such as ice- cores or bore-hole temperatures reflecting the temperature of glaciers such as Antarctica. However, it is difficult to de-convolve and combine this knowledge as proxy records are often time-uncertain, are noisy, sparse and record the climate in very different ways.

Recently, there have been advances in understanding the ice-core recording process. Based on this, proxy system models enabling the production of "digital” cores from climate model simulations, i.e. numerical forward models, were developed. Further,
bore-hole temperatures and isotope data deliver complementary information. Still, the challenge to optimally invert the process from the climate to the ice-core record and to reconstruct the climate state from such sparse, noisy and diverse data is largely unresolved.

This PhD project aims to improve on the borehole inversion methods as well as on the climate field reconstruction technique by means of modern techniques in numerical modeling and Bayesian inference to optimally combine the various information sources. In collaboration with data science and statistics experts and experts from paleo-climate research, this project aims to develop and test a new reconstruction technique that could
provide a better quantitative access of paleo-climate data and insight into the past climate evolution.
Tasks
- Set up, i.e. discretize and efficiently implement forward models, given by advection diffusion equations, for glacier bore-hole temperature profiles.
- Develop and test inversion methods for the relationship of water isotopes and temperature using Bayesian inference.
- Use advanced Bayesian hierarchical modeling techniques to combine the information from water-isotopes and borehole temperatures to reconstruct the local temperature evolution. Ideally, this will be extended to spatio-temporal field reconstructions making use of the spatial physical covariance structure from reanalysis data. You will test this model using surrogate data from simulated (‘digital’) ice-cores.
- Based on simulated cores and the developed framework, you will optimize the sampling strategy and show the feasibility and limitations of combined isotope and borehole thermometry to reconstruct the temperature evolution of Antarctica.
Requirements
- A degree (Master, Diploma) in mathematics, computer science, physics, climate sciences, or a related field.
- Strong analytical, mathematical and statistical skills.
- Proficiency in a programming language (preferably Python or C/C++).
- Excellent English language skills, both written and spoken.

PhD Research Fellow in alpine macroecology and global change biogeography related to biodiversity

Bergen, Norway
Theme
Category
Logistics
There is a vacancy for a PhD Research Fellow within the Ecological and Environmental Change Research Group at the Department of Biological Sciences. The position is for a fixed-term period of 3 years with the possibility of a 4th year with compulsory other work (e.g. teaching duties at the Department). The position is associated with Trond Mohn Stiftelse and UiB funded project called Past, Present, and Future of Alpine Biomes Worldwide (PPF-Alpine).

Tentative starting date is January 1st 2023.

Interviews will be held in the beginning of October.
Description
Alpine biomes are present on all continents and at all latitudes worldwide. They comprise biodiversity hotpots, fulfill a crucial role in hydrological and climate regulation, and provide vital support for the livelihoods and wellbeing of billions of people. Importantly, alpine biomes and their diversity are characterized by a dynamic past. Indeed, during the Quaternary glacial-interglacial cycles, they underwent multiple expansion-contraction pulses, which resulted in recurrent episodes of connection and fragmentation that likely shaped present-day biodiversity and mountain hotspot patterns. The main aim of PPF-Alpine is to decipher the role of Quaternary climate dynamics in driving present-day alpine biodiversity based on the notion that their dynamic past may hold key insights for their future resilience. The cross-disciplinary team of PPF-Alpine will do so by integrating expertise, tools, and data from glaciology, glacial geomorphology, paleoecology, biogeography, macroecology, and landscape modelling.
Tasks
The candidate will conduct analyses on observed biodiversity in alpine biomes across different scales, taxonomic groups, and biodiversity metrics. A key task is the collection, harmonization, and assessment of large biodiversity datasets from different sources, and the integration of data from different biological, climatical, and geological fields obtained from mountains worldwide. The candidate will analyse the legacy effect of potential drivers of present-day alpine biodiversity, associated to Quaternary climate fluctuations, and biogeographical and geological processes. The candidate’s outcomes are aimed to provide key insights into the alpine biome’s resilience to future climate change effects in mountains and the identification of priority regions for conservation. Working with PPF-Alpine’s team members on different science outreach products to divulgate the overall project’s outcomes will be part of your tasks.
Requirements
- Applicants must hold a master’s degree or equivalent education in biology, ecology, biogeography, or similar discipline. Master students can apply provided they complete their final master exam before 15.10.2022. It is a condition of employment that the master's degree has been awarded.
