Annual evolution of the ice–ocean interaction beneath landfast ice in Prydz Bay, East Antarctica

Abstract - - ∘ C, and then it gradually decreased to - ∘ C in May and remained at this temperature until November. The seawater salinity and density exhibited similar increasing trends during April and May, with mean rates of 0.04 psu d- 1 - 3 - 1 9.5 ± 3.9 and 0.2 ± 0.8  cm s- 1 ∘)–WSW (240∘), and the domain velocity (79 %) was 5–15 cm s- 1 F w 41.3 ± - 2 7.8 ± 2.9  W m- 2 F w values calculated using three different bulk parameterizations exhibited similar trends with different magnitudes due to the uncertainties of the empirical friction velocity. The spectral analysis results suggest that all of the observed ocean variables exhibited a typical half-day period, indicating the strong diurnal influence of the local tidal oscillations. The large-scale sea ice distribution and ocean circulation contributed to the seasonal variations in the ocean variables, revealing the important relationship between the large-scale and local phenomena. The high-frequency and cross-seasonal observations of oceanic variables obtained in this study allow us to deeply investigate their diurnal and seasonal variations and to evaluate their influences on the landfast ice evolution.
