Proposal Description: Cenozoic Formation of the Antarctic Glacial Landscape Investigated by Low-Temperature Thermochronometry
PROPOSAL DESCRIPTION: CENOZOIC FORMATION OF THE ANTARCTIC GLACIAL LANDSCAPE INVESTIGATED BY LOW-TEMPERATURE THERMOCHRONOMETRY Summary: This pre-proposal outlines a drilling program aimed at investigating the origin of the present glacial landscape in the fjord system of the western Antarctic Peninsula by applying novel methods of low-temperature thermochronometry. This, in turn, is important in understanding the Cenozoic geologic history of Antarctica and, more broadly, in understanding the role of glaciation in climate-solid Earth interactions. Accomplishing this requires samples of the present bedrock surface in the location of maximum Cenozoic erosion, that is, glacial valley bottoms. Thus, the major challenge is the inherent inaccessibility of the Antarctic landscape: the only significant regions of Antarctica that are not now covered by ice are below present sea level. To overcome this challenge, we propose to employ an IODP mission-specific platform, specifically, a semiautonomous seabed drill suitable for short coring of crystalline bedrock in formerly glaciated and now submarine fjord bottoms. In the following sections: i) we explain why understanding Cenozoic glacial erosion in Antarctica is important; ii) we describe how we propose to develop this understanding; and iii) we outline criteria for a drilling program necessary to implement this strategy. 1. The when and how of Cenozoic glacial erosion: why is it important? Understanding how and when glacial landscapes form is broadly important for two reasons. First, formation of geomorphic features diagnostic of glaciation, e.g., cirques, U-shaped valleys, and landscapes of selective linear erosion (localized glacial troughs incised into an otherwise low-relief landscape; Sugden, 1978) requires the presence of glaciers. -
Cape Adare, Borchgrevink Coast
Measure 2 (2005) Annex L Management Plan for Antarctic Specially Protected Area No. 159 CAPE ADARE, BORCHGREVINK COAST (including Historic Site and Monument No. 22, the historic huts of Carsten Borchgrevink and Scott’s Northern Party and their precincts) 1. Description of Values to be Protected The historic value of this Area was formally recognized when it was listed as Historic Site and Monument No. 22 in Recommendation VII-9 (1972). It was designated as Specially Protected Area No. 29 in Measure 1 (1998) and redesignated as Antarctic Specially Protected Area (ASPA) 159 in Decision 1 (2002). There are three main structures in the Area. Two were built in February 1899 during the British Antarctic (Southern Cross) Expedition led by C.E. Borchgrevink (1898-1900). One hut served as a living hut and the other as a store. They were used for the first winter spent on the Antarctic continent. Scott’s Northern Party hut is situated 30 metres to the north of Borchgrevink's hut. It consists of the collapsing remains of a third hut built in February 1911 for the Northern Party led by V.L.A. Campbell of R.F. Scott's British Antarctic (Terra Nova) Expedition (1910-1913), which wintered there in 1911. In addition to these features there are numerous other historic relics located in the Area. These include stores depots, a latrine structure, two anchors from the ship Southern Cross, an ice anchor from the ship Terra Nova, and supplies of coal briquettes. Other historic items within the Area are buried in guano. Cape Adare is one of the principal sites of early human activity in Antarctica. -
Antarctic Peninsula Exhumation and Landscape Development Investigated by Low-Temperature Detrital Thermochronometry
PROJECT DESCRIPTION: ANTARCTIC PENINSULA EXHUMATION AND LANDSCAPE DEVELOPMENT INVESTIGATED BY LOW-TEMPERATURE DETRITAL THERMOCHRONOMETRY I. Overview and introduction. We propose to apply methods of low-temperature thermochronometry based on the (U-Th)/He system in apatite to investigate the exhumation history, the development of the present topography, and the pattern of glacial erosion in the central Antarctic Peninsula. Recent studies have used this approach to study the dramatic, high-relief landscapes formed by Pleistocene alpine glaciation in temperate latitudes, for example in New Zealand, The Alps, British Columbia, Alaska and Patagonia (Shuster et al, 2011; Valla et al., 2011; Shuster et al., 2005; Thomson et al., 2010; Berger et al., 2008; Ehlers et al., 2006). This research has revealed not only when the glacial valleys in these landscapes formed -- which is important in understanding the relationship between Plio-Pleistocene climate change, landscape evolution, and tectonics -- but also provided new insights into the pattern and physical processes of glacial erosion. In this work, we aim to apply this approach to the similarly dramatic glacial landscape of the Antarctic Peninsula. The Antarctic Peninsula is broadly similar to alpine glacial landscapes formed in temperate latitudes during the Pleistocene in that the dominant landforms are deep, steep-sided glacial troughs. Because of the contrast in glacial history between Antarctica and temperate regions, however, we expect the timing and history of its formation to be very different. Specifically, the Antarctic Peninsula has most likely been glaciated since the Eocene (Anderson et al., 2011; Davies et al., 2012 and references therein), and Pleistocene cooling is hypothesized to have suppressed, rather than enhanced, glacial erosion by establishment of polar conditions (e.g., Rebesco et al., 2005). -
SECTION THREE: Historic Sites and Monuments in Antarctica
SECTION THREE: Historic Sites and Monuments in Antarctica The need to protect historic sites and monuments became apparent as the number of expeditions to the Antarctic increased. At the Seventh Antarctic Treaty Consultative Meeting it was agreed that a list of historic sites and monuments be created. So far 74 sites have been identified. All of them are monuments – human artifacts rather than areas – and many of them are in close proximity to scientific stations. Provision for protection of these sites is contained in Annex V, Article 8. Listed Historic Sites and Monuments may not be damaged, removed, or destroyed. 315 List of Historic Sites and Monuments Identified and Described by the Proposing Government or Governments 1. Flag mast erected in December 1965 at the South Geographical Pole by the First Argentine Overland Polar Expedition. 2. Rock cairn and plaques at Syowa Station (Lat 69°00’S, Long 39°35’E) in memory of Shin Fukushima, a member of the 4th Japanese Antarctic Research Expedition, who died in October 1960 while performing official duties. The cairn was erected on 11 January 1961, by his colleagues. Some of his ashes repose in the cairn. 3. Rock cairn and plaque on Proclamation Island, Enderby Land, erected in January 1930 by Sir Douglas Mawson (Lat 65°51’S, Long 53°41’E) The cairn and plaque commemorate the landing on Proclamation Island of Sir Douglas Mawson with a party from the British, Australian and New Zealand Antarctic Research Expedition of 1929 31. 4. Station building to which a bust of V. I. Lenin is fixed, together with a plaque in memory of the conquest of the Pole of Inaccessibility by Soviet Antarctic explorers in 1958 (Lat 83°06’S, Long 54°58’E). -

Major activities and International Thwaites Glacier Collaboration (ITGC): progress since previous Following the first ITGC field season in Hudson Mountains year involving UK in 2019-20, Joanne Johnson (BAS) and John Woodward personnel/infrastructure (Northumbria), with support from Dylan Rood and Keir Nichols (Imperial), have been preparing rock samples for 10Be dating and processing radar data. The GHC team (co- led by Johnson) have chosen a site for subglacial bedrock recovery drilling in the Hudson Mountains, currently scheduled for the 2021-22 season (postponed from 2020- 21 due to covid). The GHC team have also constructed a Holocene relative sea-level curve for Pine Island Bay. ANiSEED project (NERC-funded): Joanne Johnson & Steve Roberts (BAS), Pippa Whitehouse (Durham) and Dylan Rood (Imperial) published a paper showing Holocene thinning of Pope Glacier, in the Amundsen Sea Embayment, which implies widespread early Holocene ice sheet thinning coinciding with enhanced upwelling of warm ocean water onto the continental shelf in this important area. -
