On synoptic timescales, enhanced southerly August 2017 through August 2019. Our resulting record, flow promoted by negative NAO conditions produces higher including derived deuterium excess (dxs) values, allows an δ18O and δ2H values and lower dxs values. -

Red dots are acoustic mooring locations. 1. Introduction The US National Science Foundation (NSF) funded a project to “design and develop an integrated underwater acoustic sensor network for ice-covered seas.” Wolstenholme Fjord adjacent to Thule Air Base (TAB) in Greenland was identified to test and deploy this communication network to provide a real-time data connection between a remote transmit and a coastal receive unit via several data hops from modem to modem. The envisioned system shares features of a cell phone network where data passes from caller to receiver via cell phone towers. The fjord is covered by land-fast sea ice during spring and thus provides a stable platform from which to test, deploy, and recover a range of oceanographic and acoustic sensor systems via snowmobiles during day-light hours when air temperatures are generally above -25°C. During the first phase from Mar.-11 through Mar.-25 we conducted ice thickness surveys, placed an automated weather station (AWS) on the sea ice along with a provisional shelter and deployed an oceanographic thermistor mooring in water 110 m deep at the center of the study area. -

Abstract In order to investigate how Inuit Greenlanders in western Greenland are experiencing, responding to, and thinking about recent allegedly human-induced climate change, this dissertation ethnographically examines the lives of Greenlanders as well as Norse and Danes in the course of past historical natural climate cycles. My emphasis is on human endeavours to cultivate a future in the face of difficulties caused by climatic and environmental transformation. I recognize locals’ initiatives to carve out a future in the promotion of sheep farming and tree-planting in southern Greenland and in adaptation processes of northern Greenlandic hunters to the ever-shifting environment. -

Sammenfatning: I 2002 gennemførte Danmarks Miljøundersøgelser en recipientundersøgelse ud for Thule Air Base (TAB) for at vurdere, om aktiviteterne og specielt de efterladte dumpe på TAB har belastet det marine miljø med forurenende stoffer. Undersøgelsen viser, at der findes flere forurenings- kilder som f. eks. affaldsdumpe, som bevirker at niveauet af enkelte kontaminanter er forhøjet i området ved TAB. Undersøgelsen viser imidlertid også, at denne påvirkning er lokal inden for et nærområde på omkring 5-10 km fra TAB. -
On Weapons Plutonium in the Arctic Environment (Thule, Greenland)
Risø-R-1321(EN) On Weapons Plutonium in the Arctic Environment (Thule, Greenland) Mats Eriksson Risø National Laboratory, Roskilde, Denmark April 2002 Risø–R–1321(EN) On Weapons Plutonium in the Arctic Environment (Thule, Greenland) Mats Eriksson Risø National Laboratory, Roskilde, Denmark April 2002 Abstract This thesis concerns a nuclear accident that occurred in the Thule (Pituffik) area, NW Greenland in 1968, called the Thule accident. Results are based on dif- ferent analytical techniques, i.e. gamma spectrometry, alpha spectrometry, ICP- MS, SEM with EDX and different sediment models, i.e. (CRS, CIC). The scope of the thesis is the study of hot particles. Studies on these have shown several interesting features, e.g. that they carry most of the activity dispersed from the accident, moreover, they have been very useful in the determination of the source term for the Thule accident debris. Paper I, is an overview of the results from the Thule-97 expedition. This pa- per concerns the marine environment, i.e. water, sediment and benthic animals in the Bylot Sound. The main conclusions are; that plutonium is not transported from the contaminated sediments into the surface water in this shelf sea, the debris has been efficiently buried in the sediment to great depth as a result of biological activity and transfer of plutonium to benthic biota is low. Paper II, concludes that the resuspension of accident debris on land has been limited and indications were, that americium has a faster transport mechanism from the catchment area to lakes than plutonium and radio lead. Paper III, is a method description of inventory calculation techniques in sedi- ment with heterogeneous activity concentration, i.e. -

Greenland: Security Perspectives Jørgen Taagholt Jens Claus Hansen translated by Daniel Lufkin he Atlantic Treaty Association was established in 1950 as a group of former Opposition Members Tand politicians from parties backing NATO membership: Social Democrats, Conservative People’s Party and the Left Party. The goal of the Atlantic Treaty Association is to foster understanding of Danish mem- bership in NATO and to advocate political, economic and cultural cooperation among the member nations. Primary emphasis in the activities of the Atlantic Treaty Association is on: • Cooperation with the Baltic states and the Central and Eastern European nations • Activities with young people interested in Danish security policy • Seminars and study tours for teachers from high schools and other educational institutions • Publication of timely articles. In informational and educational activities, we em- phasize: • European security—including the expansion of the EU in depth and breadth; • The role of the United States in European security policy; • The work of NATO and the EU—looking into the future. The Atlantic Treaty Association is a private, voluntary organization whose work is financed from public and private funds.

The results show levels of plutonium in soil at Narsaarsuk ranging from background values around 39 Bq m-2 up to levels of 1.7 MBq m-2. Local sub-areas of sizes ranging from a few hundred to a few thousands of square me- -2 tres show elevated levels above 10 kBq m of plutonium. Contract no.: MST-112-00183 Based on geostatistical analysis, the total amount of pluto- nium in soil at Narsaarsuk is estimated at 270 GBq (100 g). Group's own reg. no.: Investigations were carried out at Narsaarsuk to determine the PSP 1400102-02 occurrence of radioactive particles in air.
