NFR-funded research project started on modeling waves-sea ice interactions

SIMECH: Sea Ice Mechanics, from satellites to numerical models

SIMech proposes to develop a unique sea ice model based on a new rheology that will reproduce for the first time the brittle mechanical behaviour of the sea ice cover.

The Arctic region is currently experiencing rapid changes that are mainly driven by global warming. Over the last decade, we have observed a drastic shrinkage of the Arctic sea ice cover in summer accompanied by a spectacular thinning of mean thickness and an increased export of sea ice through the Fram Strait. These changes perturb the interactions between the atmosphere and the ocean and modify the Arctic climate.

Sea Ice Modelling

Scientific Group Name: 
Sea Ice Modelling
We work on the physics of sea ice and its role in the polar climate system, combining numerical model developments and satellite remote sensing

We focus on the following research topics:

• To develop the new neXt generation Sea Ice Model, neXtSIM.

This new model includes the Maxwell elasto brittle (MEB) rheology to simulate sea ice dynamics and an adapted code to simulate sea ice thermodynamics including the feedbacks between thermodynamical and dynamical processes.

• To develop and implement a new module into neXtSIM that resolves waves-ice interactions in the Marginal Ice Zone.

SWARP: Ships and Waves Reaching Polar Regions

SWARP develops downstream services for sea ice and waves forecasting in the Arctic Marginal Ice Zone (MIZ). SWARP will integrate the new met-ocean services into contingency planning and onboard navigation softwares

SWARP will develop downstream services for sea ice and waves forecasting in the Marginal Ice Zone (MIZ) in the Arctic. Waves in ice are one of the most hazardous phenomena for vessels and industrial activities in the polar seas, but there are presently no services providing any information about either the waves themselves or their effects on the ice state (in particular the distribution of ice floe sizes). The monitoring and forecasting systems developed in SWARP aim to become operational by the middle of the project, filling a gap in the present marine services of Copernicus.

CORESAT: Combined remote and in situ study of sea ice thickness and motion in the Fram Strait

About understanding sea ice thickness and drift distribution in the Fram Strait region

The project will improve our understanding of the sea ice thickness and sea ice drift distribution in the Fram Strait region, which has a high impact on the local Arctic and global climate.

sea ice

My research focuses on sea ice physics, variability and forecast. I also look at the interactions between sea ice and the other components of the climate system, with a particular interest on the Arctic region. I have expertise in both sea ice modelling and observations statistical analysis, as well as some experience in data assimilation.

WIFAR: Waves-in-Ice Forecasting for Arctic Operators

The conjunction of waves and sea ice represents a serious threats for the offshore activities in the Marginal Ice Zone. WIFAR is introducing the effect of waves into operational forecast models of the coupled ice-ocean system.

The project is implemented over four years through 6 workpackages:

WP1: Development and validation of a wave-in-ice model based on theory by V. Squire's group in New Zealand. The model will be implemented for use in compbination with an operational ice-ocean model developed at NERSC, first as a heuristic, then as coupled model.

WP2: Operational ice-ocean model development with a new MIZ ice rheology aiming to provide improved forecasts of ice edge, concentration, thickness and drift.
