The Impact of Tides on Simulated Landfast Ice in a Pan-Arctic Ice-Ocean Model
International audience The impact of tides on the simulated landfast ice cover is investigated. Pan-Arctic simulations are conducted with an ice-ocean (CICE-NEMO) model with a modified rheology and a grounding scheme. The reference experiment (without tides) indicates there is an overestimation of t...
