Natural hazard risk is assessed by leveraging, among other things, the historical record. However, if the record is short then there is the danger that risk models are not capturing the true envelope of natural variability. In the case of tropical cyclones in Australia, the most reliable observational record spans less than 50 years. Here, we use a much longer (ca. 6000-year) chronology of intense paleo-cyclones and, for the f...

Changes in the intensity and position of subtropical anticyclones are major drivers of wave climate around Australia. The quasi‐stationary ridge of high atmospheric pressure in the mid‐latitudes is known as the Subtropical Ridge (STR). In this study, we decompose the directional wave climate along the Western Australian Shelf (WAS) into three primary modes of variability using a statistical‐synoptic typing approach, and relate...

A Russian‐American fieldwork effort on Lake Baikal, its tributaries, and surrounding hot springs was undertaken in June–July 1991. Here we report on aspects of major ion (Ca 2+ , Mg 2+ , Alk, Cl − , SO 4 2− ) and several minor and trace element (Li isotopes, Sr isotopes, Ba, Al, V, Cr, Ni, Cu, Ge, Cd, Hg, U) cycles. Our riverine data for major ions generally concur with the more extensive, time‐averaged Russian database; for t...
