Sims Island: first data from a Pliocene alkaline volcanic centre in eastern Ellsworth Land
Although Sims Island (73°17′S/78°33′W), a bedrock peak in Carroll Inlet on the English Coast of eastern Ellsworth Land (Fig. 1), had previously been observed and photographed from the air (e.g. Rowley & Thomson 1990, fig. C.6.2), no landing had been made prior to the present study. Based on prox...
