Polynyas occurrence time
WebOct 2, 2024 · regions at times and under climatic conditions where one would expect the water to be ice covered. There are generally considered to be two types of polynyas (Smith et al., 1990): latent heat polynyas (also referred to as mechanically gener-ated or wind-driven polynyas) and sensible heat polynyas. WebIsotopic curves have been used as approximative estimators of global sea level. Calculations of the amplitude of sea-level variations during Interglacials, especially for the last Interglacial, are based on the study of emerged coral terraces.
