| Summary: | <!--!introduction!--> The interactions between surface waves and sea ice are a rich set of scientific problems. For example, wave orbital motions inhibit ice skin-over, Langmuir circulations and turbulence from breaking are thought to advect surface-formed ice crystals into the water column, and wave-driven turbulence affects the vertical heat transfer that controls ice formation. These phenomena are becoming increasingly relevant as decreasing sea ice results in larger waves over a longer season in the Arctic Ocean. Tantalizing numerical simulations have suggested that, for example, observed streak structures of ice on the sea surface are indeed related to wave forcing. However, almost no previous experimental studies have tackled the problem. In this presentation, results from two recent field campaigns will be presented, one in the Arctic (during DarkEdge 2021), and one in the St. Lawrence Estuary (WAAXT 2023), that were specially designed to illuminate the role of waves and wave-driven turbulence ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
