This complex of two polygonal office towers connected by an atrium, presents a unique silhouette—and plenty of headaches for the surveying team—thanks to its twisted architecture. The European Central Bank (ECB) is constructing its new headquarters on the site of the historic Großmarkthalle (wholesale market) in Frankfurt. The design of Vienna-based architects COOP HIMMELB(L)AU consists of three main elements: the former Großmarkthalle with new internal structures; a 185-m (610-ft) asymmetric double office tower with connecting atrium; and an entrance building. The entrance building creates a visual and functional link between the high-rise and the Großmarkthalle and houses the press conference area. Once ready for occupancy, the facility will provide employment for around 2,300 workers, mainly in the office towers. The restored Großmarkthalle will largely retain its appearance and provide a historic venue for the ECB’s public functions, with a lobby, visitor center, conference area, library, ex- hibition spaces and a restaurant. Gross floor area of the premises—scheduled for completion by the end of 2013, with staffing by 2014—will total approximately 185,000 m2 (45.7 ac or 1.99 million ft2).

  • Ellsworth Mountains, Overview Antarctica Mt
    AAC Publications Ellsworth Mountains, Overview Antarctica Mt. Vinson (4,892m) continues to attract large numbers. One hundred and seventy individual climbers reached the summit during the 2012-13 season (a total of 184 successful ascents). Fourteen guides made two or more ascents. Only four clients failed to top out. Neighboring Mt. Shinn (4,660m) received five ascents. American guide Robert Anderson and his clients did the probable first ascent of a 2,880m peak five kilometers south of Vinson base camp. This attractive ice peak forms a pyramidal end to the ridge dividing the Cairns and Tulaczyk glaciers, the unclimbed southern arm of the western ridge of the Vinson Massif. In late December, Antarctic Logistics & Expeditions (ALE) guides Maria Paz “Pachi” Ibarra and Todd Passey led the returning German client Ralf Laier on the first ascents of three peaks: Mt. Allen (3,430m) and Mt. Liptak (3,052m) in the southern Sentinel Range, and Robinson Peak (2,038m) further south in the Heritage Range. Allen was climbed from the south, ending in a difficult corniced ridge, and took two attempts. Liptak had a mixed summit ridge of loose rock, after steep snow and ice on the northern slope. Robinson Peak, a rocky summit in the Pioneer Heights Range, was approached from the west, across the Rennell Glacier, and then climbed by the south ridge, with some technical rock pitches and exposed scrambling. The trio traversed the summit to the northern side, and traveled back around the east to reach their skis on the southern col. Further south, in the Independence Hills, Scott Webster and friends made the first ascent of an elegangt unnamed ice peak north of Beitzel Peak and just south of the famous Minaret Peak, a distinctive rock tower visible to all who flew out of the old ANI base at Patriot Hills.

  • Mt. Gardner, Ascent; Mt
    New altitude survey; Mt. Craddock, west face; Mt. Gardner, ascent; Mt. Tyree, attempt. As a continuation of previous GPS work on Mt. Shinn (2002), Livingston Island (2003), and the Vinson Massif (2004), another expedition from the Omega Foundation planned to climb and measure Mts. Tyree, Craddock, and Gardner during 2005-06. These mountains were believed to be the second, fourth and fifth highest, respectively, in Antarctica. On November 23 we landed on a previously unvisited glacier west of Mt. Craddock and set up base camp, lower than expected, at 1,455m. During the following days we climbed a small vir­ gin 1,978m peak to the west (via the east face and north ridge on the 24th; 500m; PD), sledged loads farther up the glacier, and made an advanced base at 2,041m, close beneath the west face of Craddock. All the team climbed the lower slopes of the face and dug a site out of a rock ridge for Camp 1 (3,258m). Steve Chaplin (U.K.) and I spent four nights there in poor weather. December 7 was a brilliant day, and we quickly climbed the 45° snow and ice slopes of the 1,000m upper west face to reach the summit in the eve­ ning. The climbing was never diffi­ cult but sustained and sometimes on ice, so a fall would have been serious. The 2,300m route was AD. There are no flat places to put a tent, hence our excavation of the ridge. This was the second ascent of Craddock, first climbed by Conrad Anker and Jay Smith in 1992 by a dif­ ferent route from the west, accessed from the glacial basin to the north of ours.

Bristol Glaciology Centre, School of Geographical Sciences, University of Bristol, 14 Bristol BS8 1SS 15 16 ABSTRACT 17 Antarctic subglacial highlands are where the Antarctic ice sheets first developed 18 and the ‘pinning points’ where retreat phases of the marine-based sectors of the 19 ice sheet are impeded. Due to low ice velocities and limited present-day change in 20 the ice sheet interior, West Antarctic subglacial highlands have been overlooked 21 for detailed study. These regions have considerable potential, however, for 22 establishing from where the West Antarctic Ice Sheet (WAIS) originated and grew, 23 and its likely response to warming climates. Here, we characterize the subglacial 24 morphology of the Ellsworth Subglacial Highlands (ESH), West Antarctica, from 25 ground-based and aerogeophysical radio-echo sounding (RES) surveys and the 26 MODIS Mosaic of Antarctica. We document well-preserved classic landforms 27 associated with restricted, dynamic, marine-proximal alpine glaciation, with 28 hanging tributary valleys feeding a significant overdeepened trough (the Ellsworth 29 Trough) cut by valley (tidewater) glaciers.

Box 515, Waconia, Minnesota U.S.A. 55387 ([email protected]) Abstract The highest peak in Antarctica, the Vinson Massif (78º35’S, 85º25’W), is at an elevation of 4892 m (16,046 ft), as determined in 2004. Measurements of the elevation have fluctuated over the years, from its earliest surveyed elevation of 5140 m (16,859 ft), to its present height. Vinson Massif and three of its near neighbors in the Sentinel Range of the Ellsworth Mountains are the highest peaks in Antarctica, making them a favorite objective of mountaineers. Well over 1,100 people have climbed Vinson since the first ascent by a team in the 1966-67 austral summer. The range is composed of Crashsite quartzite, making the Sentinel’s very resistant to erosion. Very accurate elevations have been achieved annually by GPS mapping done by a climbing team sponsored by the Omega Foundation, active in Antarctica since 1998. The Craddock Massif now includes Mt. Craddock, the ninth highest peak in Antarctica, at 4368 m (14,327 ft). Both are named for Campbell Craddock*, a U.S. geologist active in Antarctic research beginning in 1959-60. *Deceased, 23 July 2006. Citation: Gildea, D., and J.
