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).

Mcmurdo Dry Valleys, Southern Victoria Land
Measure 1 (2004) Annex Management Plan for Antarctic Specially Managed Area No. 2 MCMURDO DRY VALLEYS, SOUTHERN VICTORIA LAND 1. Description of values to be protected and activities to be managed The McMurdo Dry Valleys are characterized as the largest relatively ice-free region in Antarctica with approximately thirty percent of the ground surface largely free of snow and ice. The region encompasses a cold desert ecosystem, whose climate is not only cold and extremely arid (in the Wright Valley the mean annual temperature is –19.8°C and annual precipitation is less than 100 mm water equivalent), but also windy. The landscape of the Area contains glaciers, mountain ranges, ice-covered lakes, meltwater streams, arid patterned soils and permafrost, sand dunes, and interconnected watershed systems. These watersheds have a regional influence on the McMurdo Sound marine ecosystem. The Area’s location, where large-scale seasonal shifts in the water phase occur, is of great importance to the study of climate change. Through shifts in the ice-water balance over time, resulting in contraction and expansion of hydrological features and the accumulations of trace gases in ancient snow, the McMurdo Dry Valley terrain also contains records of past climate change. The extreme climate of the region serves as an important analogue for the conditions of ancient Earth and contemporary Mars, where such climate may have dominated the evolution of landscape and biota. The Area is characterized by unique ecosystems of low biodiversity and reduced food web complexity. However, as the largest ice-free region in Antarctica, the McMurdo Dry Valleys also contain relatively diverse habitats compared with other ice-free areas. -
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. -

Draft ASMA Plan for Dry Valleys
Measure 18 (2015) Management Plan for Antarctic Specially Managed Area No. 2 MCMURDO DRY VALLEYS, SOUTHERN VICTORIA LAND Introduction The McMurdo Dry Valleys are the largest relatively ice-free region in Antarctica with approximately thirty percent of the ground surface largely free of snow and ice. The region encompasses a cold desert ecosystem, whose climate is not only cold and extremely arid (in the Wright Valley the mean annual temperature is –19.8°C and annual precipitation is less than 100 mm water equivalent), but also windy. The landscape of the Area contains mountain ranges, nunataks, glaciers, ice-free valleys, coastline, ice-covered lakes, ponds, meltwater streams, arid patterned soils and permafrost, sand dunes, and interconnected watershed systems. These watersheds have a regional influence on the McMurdo Sound marine ecosystem. The Area’s location, where large-scale seasonal shifts in the water phase occur, is of great importance to the study of climate change. Through shifts in the ice-water balance over time, resulting in contraction and expansion of hydrological features and the accumulations of trace gases in ancient snow, the McMurdo Dry Valley terrain also contains records of past climate change. The extreme climate of the region serves as an important analogue for the conditions of ancient Earth and contemporary Mars, where such climate may have dominated the evolution of landscape and biota. The Area was jointly proposed by the United States and New Zealand and adopted through Measure 1 (2004). This Management Plan aims to ensure the long-term protection of this unique environment, and to safeguard its values for the conduct of scientific research, education, and more general forms of appreciation. -

Authors' Response to Reviews Dear Editors, We Appreciate the Two
Authors’ Response to Reviews Dear editors, We appreciate the two reviewers’ thoughtful comments and detailed assessment of the archive. We have provided our detailed responses to the both reviewers’ questions in red, as well as the revised manuscript with associated tracked changes, below. Warwick Vincent I could not find the supplementary material (Table S1) that is referred to. Thank you for bringing this to our attention, we have uploaded the supplementary material (Table S1) with the revised manuscript. Concerning data quality: the data set is accessible via the given identifier, and is complete as a first collection that can now be updated. The data quality is variable – some images are only poorly resolved and have many imperfections (e.g. dust on the slide lens or scanner, poor color rendition), and the metadata are not always complete be-cause the exact date is unknown. The authors might note this by saying that the quality and resolution are variable, but an inclusive approach was taken to maximize the scope of the database. We agree that it is important to note the variable quality of the data and metadata and have added an explanation to the revised manuscript as suggested. Further points: The images are taken by many people and "copyright for each item re-mains with the respective contributor" – in that case, how would permission be obtained to reproduce any of these materials, for example in another publication? Unless otherwise stated, copyright for each item in the database remains with the respective contributor. If a reader wanted to gain permission to use the material in another venue, they would need to contact us or the copyright holder directly. -

Scientific Information 2001/2002 Annual New Zealand
Scientific Information 2001/2002 Annual New Zealand Forward Plans LGP The Latitudinal Gradient Project (LGP) is aimed at increasing the understanding of the coastal marine, freshwater and terrestrial ecosystems that exist along the Victoria Land coastline in the Ross Sea region, and describing potential environmental variability that may occur in the future. Antarctica New Zealand is providing the logistical capabilities for research camps to be located at specific sites along the Victoria Land coast. Thus, the opportunity to work at particular locations in collaboration with other scientists from various disciplines and National Antarctic Programmes is provided. LGP has been formally incorporated into the SCAR programme RiSCC (Regional Sensitivity to Climate Change). Certain data collected within the LGP will be housed and made available within the RiSCC database framework. Details on how the data will be shared and the timing of when the data will be made available have yet to be decided. It is intended that publications arising from the LGP will be published in a special issue of a refereed journal. Research under the LGP will be both ship-based and land-based. At present, ship-based research, funded under the Ministry of Fisheries’ BioRoss programme and the Italian Antarctic Programme, has been scheduled for January to March 2004 with a research voyage planned using two vessels aimed at supporting near-shore and deep-water marine research. The vessels dedicated to this research are NIWA’s RV Tangaroa, and the Italian Antarctic Programme’s RV Italica. Further information about the ship-based research can be found in the BioRoss research plan and in the BioRoss call for statements of interest.
