A Decade of Antarctic Science Support Through Amps
A DECADE OF ANTARCTIC SCIENCE SUPPORT THROUGH AMPS BY JORDAN G. POWERS, KEVIN W. MANNING, DAVID H. BROMWICH, JOHN J. CASSANO, AND ARTHUR M. CAYETTE AMPS, a real-time mesoscale modeling system, has provided a decade of service for scientific and logistical needs and has helped advance polar numerical weather prediction as well as understanding of Antarctica. ith 2011 marking the 100th anniversary of Roald Amundsen’s being the first to reach W the South Pole, the Antarctic endeavor has come a long way. The capabilities to support it have as well. In the critical area of weather forecasting, the Antarctic Mesoscale Prediction System (AMPS) has exemplified this progress for the past decade. AMPS is a real-time implementation of the Weather Research and Forecasting model (WRF; Skamarock et al. 2008) to support the U.S. Antarctic Program (USAP). Because the need for accurate weather fore- casting in Antarctica has been acute since the earliest explorations, AMPS has been a vital effort. AMPS began in 2000, when the National Science Foundation’s (NSF’s) Office of Polar Programs (OPP) sought to improve the weather forecasting support for FIG. 1.

The concern at the time was the numerical regions shown. weather prediction (NWP) guidance available to the USAP forecasters, who were relying on an assortment It became evident early in the effort that the of models (mostly global) that were tailored neither to system could be of value to Antarctic activities their needs nor to their singular area of responsibility. beyond those tied to the McMurdo forecasters. -

Macphail2 and E.M. Truswell3 ABSTRACT Twenty-three core catcher samples from Site 1166 (Hole 1166A) in Prydz Bay were analyzed for their palynomorph content, with the aims of determining the ages of the sequence penetrated, providing informa- tion on the vegetation of the Antarctic continent at this time, and determining the environments under which deposition occurred. Di- nocysts, pollen and spores, and foraminiferal test linings were recov- ered from most samples in the interval from 142.5 to 362.03 meters below seafloor (mbsf).

Trophic Interactions Within the Ross Sea Continental Shelf Ecosystem Walker O

We review the available data on the region’s physical characteristics (currents and ice concentrations) and their spatial variations, as well as components of the neritic food web, including lower and middle levels (phytoplankton, zooplankton, krill, fishes), the upper trophic levels (seals, penguins, pelagic birds, whales) and benthic fauna. A hypothetical food web is presented. Biotic interactions, such as the role of Euphausia crystallorophias and Pleuragramma antarcticum as grazers of lower levels and food for higher trophic levels, are suggested as being critical. The neritic food web contrasts dramatically with others in the Antarctic that appear to be structured around the keystone species Euphausia superba. Similarly, we suggest that benthic–pelagic coupling is stronger in the Ross Sea than in most other Antarctic regions. We also highlight many of the unknowns within the food web, and discuss the impacts of a changing Ross Sea habitat on the ecosystem.

ISBN: 978-39809668-63 5 FORSCHUNG, GEFÄHRDUNG UND SCHUTZ Die Polarregionen sind durch extreme Bedingungen und ihre seit Jahrmillionen vom Eis geprägten Landschaften schwer zugänglich. Nicht zuletzt aufgrund dieser Umweltbedingungen begann ihre umfassende Erforschung erst im 20. Jahrhundert. Eine wissenschaftliche Zusammenarbeit in der Antarktis fing während des Internationalen Geophysikalischen Jahres (IGY) 1957/58 an. Sie wird bis heute von dem 1958 gegründeten nicht-staatlichen Scientific Committee on Antarctic Research (SCAR) gefördert und international koordiniert. Zwölf Staaten, die während des IGY in der Antarktis Forschungsstationen eingerichtet hatten, unterzeichneten 1959 den Antarktis- vertrag, der die friedliche Nutzung und die internationale wissenschaftliche Kooperation langfristig festschrieb. Bis heute traten weitere 36 Staaten diesem Vertragswerk bei. Sein Konsultativstatus fordert einerseits »conduc- ting substantial research activities« und gewährt andererseits Mitsprache bei der Verabschiedung von Empfeh- lungen, Entscheidungen und Beschlüssen. Eine internationale Zusammenarbeit zur Erforschung der Arktis war während des »Kalten Krieges« aus- sichtslos. Die USA und die UdSSR standen sich in dieser Region mit ihrem Nukleararsenal direkt gegenüber. Erst durch die politischen Veränderungen in der Sowjetunion eröffneten sich erste Perspektiven. 1990 wurde als nicht-staatliche -

The Ross Sea: a Valuable Reference Area to Assess the Effects of Climate Change
IP (number) Agenda Item: CEP 7e, ATCM 13 Presented by: ASOC Original: English The Ross Sea: A Valuable Reference Area to Assess the Effects of Climate Change 1 IP (number) Summary International Panel on Climate Change models predict that the Ross Sea will be the last portion of the Southern Ocean with sea ice year round. Currently, the Ross Sea ecosystem is considered to be relatively little affected by direct human-related impacts other than the past exploitation of marine mammals along its slope and the recent exploratory Antarctic toothfish fishery. The indirect human impacts of CO2 pollution on melting ice and ocean acidification have yet to be felt. The Ross Sea - with its several very long biotic and hydrographic data sets - constitutes an important reference area to gauge the ecosystem effects of climate change and distinguish those effects from the effects of current fisheries, tourism, and historic overexploitation and recovery or lack of recovery of some seal, whale, and fish populations elsewhere. This, in conjunction with a range of other scientific and biological reasons that has been laid out in prior ASOC papers, underpins why the Ross Sea should be included as a key component in the network of marine protected areas currently being considered for the Southern Ocean by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). 1. Introduction Over the past few years, ASOC has put forward a number of papers making the ‘science case’ for supporting full protection of the Ross Sea slope and shelf,1 in the context of establishing an important component of a representative network of MPAs in the Southern Ocean.2 This paper focuses on the climate reference zone potential of the Ross Sea. -

1. Leg 189 Summary1
Exon, N.F., Kennett, J.P., Malone, M.J., et al., 2001 Proceedings of the Ocean Drilling Program, Initial Reports Volume 189 1. LEG 189 SUMMARY1 Shipboard Scientific Party2 ABSTRACT The Cenozoic Era is unusual in its development of major ice sheets. Progressive high-latitude cooling during the Cenozoic eventually formed major ice sheets, initially on Antarctica and later in the North- ern Hemisphere. In the early 1970s, a hypothesis was proposed that cli- matic cooling and an Antarctic cryosphere developed as the Antarctic Circumpolar Current progressively thermally isolated the Antarctic continent. This current resulted from the opening of the Tasmanian Gateway south of Tasmania during the Paleogene and the Drake Pas- sage during the earliest Neogene. The five Leg 189 drill sites, in 2463 to 3568 m water depths, tested, refined, and extended the above hypothesis, greatly improving under- standing of Southern Ocean evolution and its relation with Antarctic climatic development. The relatively shallow region off Tasmania is one of the few places where well-preserved and almost-complete marine Cenozoic carbonate-rich sequences can be drilled in present-day lati- tudes of 40°–50°S and paleolatitudes of up to 70°S. The broad geological history of all the sites was comparable, although there are important differences among the three sites in the Indian Ocean and the two sites in the Pacific Ocean, as well as from north to south. In all, 4539 m of core was recovered with an excellent overall recov- ery of 89%, with the deepest core hole penetrating 960 m beneath the seafloor. The entire sedimentary sequence cored is marine and contains a wealth of microfossil assemblages that record marine conditions from the Late Cretaceous (Maastrichtian) to the late Quaternary and domi- nantly terrestrially derived sediments until the earliest Oligocene. -
