BUOYS: More about the project and the team:

A variety of synoptic, seasonal and interannual drivers influence the forms, types and concentration of sea ice in the Marginal Ice Zone (MIZ) in the Southern Ocean. The temporal and spatial distribution of the ice and its physical, mechanical and biological properties are directly related to the natural variability of the oceans and atmosphere, but also anthropogenic climate change. Climate and Earth System Models have limited sea ice variable parameterisations due to the scarcity of spatially distributed high resolution measurements from the region, specifically during winter/spring. To better understand atmosphere-ice-ocean MIZ processes and to improve future prediction of seasonal sea ice coverage and extent, three main approaches are available: (1) in situ measurements, (2) area-wide satellite data, and (3) numerical and experimental modelling. The meaningful connection of these is essential for enhancing understanding of this region. 

Improved use of technology and autonomous devices, capable of persistent in situ sampling at finer spatial resolutions over the winter/spring seasons in the Antarctic MIZ, are key to obtaining the datasets needed to improve Earth System Models and to validate remote-sensing products. This requires a multidisciplinary approach including engineering, oceanography and climate science. The #SCALEwin22 expedition BUOY team comprises researchers and students from several institutes including the University of Cape Town (Robyn, Michael, Justin, Lawrence, Agoritsa and Francesca), Nelson Mandela University (Jacques), University of Melbourne (Guilio and Ippolita), University of East Anglia (Alberto) and the Finnish Meteorological Institute – FMI (Jan-Victor). During the expedition we aim to collect high-frequency wave and ice drift data using ice-tethered buoys (see images below) designed and built by the UCT team as well as open water buoys developed by Tallinn University of Technology and WiseParker OÜ. These measurements will be complimented by advanced ship-based imaging of ice floes and waves using LiDAR, stereo and thermal cameras. These unique high resolution data sets will be used to better characterise wave drivers of sea ice formation during winter and to inform Southern Hemisphere climate predictability.
