The general mission is to develop research work based on the development and use of the Lagrangian iceberg module implemented in the NEMO ocean model (https://www.nemo-ocean.eu). The selected candidate will contribute to the OCEAN:ICE Horizon Europe project (https://ocean-ice.eu).
Ice sheet acceleration has increased the flux of icebergs over the last 30 years, which will accelerate further in the future. Icebergs significantly impact the intrusions of warm water towards ice shelves and the Southern Ocean in general. When drifting away from their calving site, icebergs can ground on relatively shallow bathymetric ridges. This induces large areas of multi-year sea ice fastened to these icebergs, as well as subsequent polynyas which may impact dense water formation or ice-shelf melt (Bett et al. 2020). However, the influence of these changes cannot be assessed because current iceberg models are based on overly simple physics, with little consideration of links between icebergs and ice-shelf thickness, bathymetry or sea-ice stress.
- Develop the Lagrangian iceberg module currently implemented in NEMO (Marsh et al. 2015, Merino et al. 2016) by improving the iceberg thickness based on ice shelf characteristics (other possible developments are related to the interaction between icebergs and sea ice).
- Test these developments and use them to address research questions in global or circum-Antarctic ocean simulations
- Monitor the upcoming publications and write scientific articles.
- Present results in international conferences.
- Participate to the OCEAN:ICE and IGE activities (meetings, seminars, etc).
The selection will be based on the following scientific and technical criteria:
- Demonstrated experience in ocean modelling (using NEMO or other models).
- Demonstrated experience Fortran and Python coding.
- Demonstrated experience in scientific writing.
- Good understanding of the climate system, possibly including glaciological aspects.
- Motivation to disseminate scientific results.
The selection panel will also consider the gender balance of the entire research team.
The Institute for Environmental Geosciences (IGE) is a public research institute under the affiliation of CNRS, IRD, University Grenoble Alpes, and Grenoble-INP. It brings together about 250 people, including 150 permanent members (researchers, teacher-researchers, engineers) and about a hundred contractual agents (doctoral students, postdocs, engineers and technicians). The institute also welcomes several dozen trainees and scientific visitors every year. It is located on two sites of the Grenoble University Campus (GLACIOLOGY and OSUG-B/MCP) that are 5 minutes away from each other. IGE is one of the main institutes within the Observatoire des Sciences de l'Univers de Grenoble (OSUG) which is a federative structure of INSU.
The selected candidate will join the CryoDyn team which has a focus on ice dynamics and connections to the climate system. The person will be supervised by Nicolas Jourdain and Pierre Mathiot.
Constraints and risks
The research will be carried out in either French or English, however it is expected that the non-French speaking candidate will strive to learn the basics of French in order to facilitate communication and integration into the laboratory.
