Evidence is presented for a more extensive ice cover over South Georgia, the South Orkney Islands, the South Shetland Islands, and the tip of the Antarctic Peninsula. Ice extended across the adjacent submarine shelves to a depth of 200 m below present sea level. Troughs cut into the submarine shelves by ice streams or outlet glaciers and ice-scoured features on the shelf areas suggest that the ice caps were warm-based. The South Shetland Islands appear not to have been overrun by continental ice. Geomorphological evidence in two island groups suggests that the maximum ice cover, which was responsible for the bulk of glacial erosion, predates at least one full glaciation. Subsequently there was a marine interval and then a glaciation which overran all of the lowlying peninsulas. The Falkland Islands, only 2° of latitude north of South Georgia, were never covered by an ice cap and supported only a few slightly enlarged cirque glaciers. This suggests that the major oceanographic and atmospheric boundary represented by the Antarctic Convergence, which is presently situated between the Falkland Islands and South Georgia, has remained in a similar position throughout the glacial age. Its position is probably bathymetrically controlled.

Glacial Advance

Raised beach ridges on Livingston Island of the South Shetland Islands display variations in both quantity and source of ice rafted detritus (IRD) received over time. Whereas the modern beach exhibits little IRD, all of which is of local origin, the next highest beach (∼250 14C yr BP) has large amounts, some of which comes from as far away as the Antarctic Peninsula. Significant quantities of IRD also were deposited ∼1750 14C yr BP. Both time periods coincide with generally cooler regional conditions and, at least in the case of the ∼250 yr old beach, local glacial advance. We suggest that the increases in ice rafting may reflect periods of greater glacial activity, altered ocean circulation, and/or greater iceberg preservation during the late Holocene. Limited IRD and lack of far-travelled erratics on the modern beach are both consistent with the ongoing warming trend in the Antarctic Peninsula region.

The present paper describes 10 new diatom (Bacillariophyta) species from the Maritime Antarctic Region. Five of the newly described taxa: Caloneis australis sp. nov., Mayamaea sweetloveana sp. nov., Navicula romanedwardii sp. nov., Sellaphora antarctica sp. nov. and Sellaphora gracillima sp. nov. have been previously reported from the Antarctic Region but were force-fitted into incorrect names. Five other taxa: Chamaepinnularia elliptica sp. nov., Cosmioneis regigeorgiensis sp. nov., Mayamaea tytgatiana sp. nov., Muelleria pimpireviana sp. nov. and Pinnularia pinseeliana sp. nov. are newly discovered taxa. The morphology of all new species is studied using both light and scanning electon microscope observations and compared with similar species from the Antarctic Region and worldwide. Data about the ecology and confirmed Antarctic distribution of the new species are added.

ABSTRACTThe celebrated meeting between Captain Bellingshausen of the Imperial Russian Navy and the American sealing skipper Nathaniel Brown Palmer, off the South Shetland Islands in February 1821, has often been described by following just one or other of the two men's divergent and in some respects irreconcilable accounts. The most contentious issue is whether or not Palmer told Bellingshausen about the existence of a body of land to the south of the South Shetlands, known today as the Antarctic Peninsula. This note attempts to reach a balanced assessment of the matter by examining evidence from both sides, including several previously unconsidered items. It concludes that, although the truth will never be known with absolute certainty, the basic American account is more plausible, by the narrowest of narrow margins, than the Russian.
