High-Resolution Thermal Imaging in the Antarctic Marginal Ice Zone: Skin Temperature Heterogeneity and Effects on Heat Fluxes

Sep 25, 2023alessandro

This article was published on 14 September 2023. 👤 Ippolita Tersigni, Alberto Alberello, Gabriele Messori, Marcello Vichi, Miguel Onorato, Alessandro Toffoli Abstract Insufficient in situ observations from the Antarctic marginal ice zone (MIZ) limit our understanding and description of relevant mechanical and thermodynamic processes that regulate the seasonal sea ice cycle. Here we present high-resolution

A satellite altimetry data assimilation approach to optimise sea state estimates from vessel motion

Jan 31, 2023alessandro

This article was published on 31 January 2023. 👤 Filippo Nelli, Marzieh H. Derkani, Alberto Alberello, Alessandro Toffoli Abstract Estimates of directional wave spectra and related parameters can be obtained from ship motion data through the wave-buoy analogy approach. The fundamental input is the response amplitude operator (RAO), which translates ship response into a wave

Modelling attenuation of irregular wave fields by artificial ice floes in the laboratory

This article was published on 12 September 2022. 👤 A. Toffoli, J. P. A. Pitt, A. Alberello and L. G. Bennetts Abstract A summary is given on the utility of laboratory experiments for gaining understanding of wave attenuation in the marginal ice zone, as a complement to field observations, theory and numerical models. It is

Installation of Sea State Cameras on the Aurora Australis

Oct 10, 2018alessandro

On October 9, 2018, we have installed a stereo camera system on the Aurora Australis, the Australian icebreaker, within the AAS project 4431 (CAMPCANN), led by Dr Robyn Shofield (School of Science of The University of Melbourne). The camera will operate from October 2018 to March 2019 and will monitor the ocean surface, including the
