  • Data Structure
    Data structure – Water The aim of this document is to provide a short and clear description of parameters (data items) that are to be reported in the data collection forms of the Global Monitoring Plan (GMP) data collection campaigns 2013–2014. The data itself should be reported by means of MS Excel sheets as suggested in the document UNEP/POPS/COP.6/INF/31, chapter 2.3, p. 22. Aggregated data can also be reported via on-line forms available in the GMP data warehouse (GMP DWH). Structure of the database and associated code lists are based on following documents, recommendations and expert opinions as adopted by the Stockholm Convention COP6 in 2013: · Guidance on the Global Monitoring Plan for Persistent Organic Pollutants UNEP/POPS/COP.6/INF/31 (version January 2013) · Conclusions of the Meeting of the Global Coordination Group and Regional Organization Groups for the Global Monitoring Plan for POPs, held in Geneva, 10–12 October 2012 · Conclusions of the Meeting of the expert group on data handling under the global monitoring plan for persistent organic pollutants, held in Brno, Czech Republic, 13-15 June 2012 The individual reported data component is inserted as: · free text or number (e.g. Site name, Monitoring programme, Value) · a defined item selected from a particular code list (e.g., Country, Chemical – group, Sampling). All code lists (i.e., allowed values for individual parameters) are enclosed in this document, either in a particular section (e.g., Region, Method) or listed separately in the annexes below (Country, Chemical – group, Parameter) for your reference.

Especially convincing is evidence, presented by DAMASKE & OAKEY (2006), that at least one basic dyke of Neoproterozoic age extends across Smith Sound from Inglefield Land to inshore eastern Ellesmere Island without any recognizable strike slip offset. INTRODUCTION These results confirm that no major sinistral fault exists in southern Nares Strait. It is apparent to both earth scientists and the general public To account for the absence of a Wegener Fault in most parts of Nares Strait, that the shape of both coastlines and continental margins of the present paper would locate the late Paleocene-Eocene Greenland plate boundary on an interconnected system of faults that are 1) traced through western Greenland and eastern Arctic Canada provide for a Jones Sound in the south, 2) lie between the Eurekan Orogen and the Precam- satisfactory restoration of the opposing lands.

The user has requested enhancement of the downloaded file. ARCTIC RIFT COPPER Part of world’s newest metallogenic province: Kiffaanngissuseq Technical Assessment Report Greenfields Exploration Ltd November 2020 This report presents a holistic view of north eastern Greenland’s geology. The empirical evidence of mineralisation and geological record are tied in with mineral system components from global through to prospect scales. The source rocks, geodynamic triggers, pathways, and deposition sites are all identified within a preserved terrane. This work defines the Kiffaanngissuseq metallogenic province, a previously undescribed mineral system. For the first time, we identify a c. 1,250 Ma orogenic event in the basement as the geodynamic trigger related to the basalt- hosted native copper within the Arctic Rift Copper project. A c. 385 Ma fluid migration is identified as the trigger for a second copper-sulphide mineralising event expressed within the project, that also emplaced a distal zinc deposit within Kiffaanngissuseq. This multi-episodal mineral system is supported by a regional geochemical and hydrodynamic framework that is not articulated elsewhere.

The view, west of Mestersvig (located on map, page 4), is north over Bersærkerbræ and the northern part of the Stauning Alper to Kong Oscar Fjord with Traill Ø in the right backgro- und. The mountains up to 1800 m high are of the Neoproterozoic Eleonore Bay Supergroup. To the right: first author Niels Henriksen, for many years head of geological mapping at GGU/GEUS, and participant in field work in Greenland for more than 45 years. Frontispiece: facing page Major Caledonian syncline involving reactivated Archaean basement gneisses containing amphibolite bands. Overlying rusty coloured Mesoproterozoic metasediments (Krummedal supracrustal sequence) just visible in tight core of the fold. The intensity of deformation in the syncline clearly increases towards the core, where the basement gneisses become more strongly foliated. Some of the amphibolite bands were derived from cross-cutting basic intrusions, which are still discernable in the less severely deformed parts of the Archaean basement (Fig. 17, p. 31). The height of the section is c. 2000 m.

  • Stratigraphy and Depositional Evolution of the Upper Palaeozoic Sedimentary Succession in Eastem Peary Land, North Greenland
    Stratigraphy and depositional evolution of the Upper Palaeozoic sedimentary succession in eastem Peary Land, North Greenland Lars Stemmerik, Eckart Håkansson, Lena Madsen, Inger Nilsson, Stefan Piasecke, Sylvie Pinard2 and Jan A. Rasmussen The Upper Palaeozoic Foldedal and Kim Fjelde formations in eastem Peary Land are redefined on the basis of new biostratigraphic data, including fusulinids, conodonts, palynomorps and small foraminifera. The Foldedal Formation in its new definition includes alllate Moscovian to Gzelian deposits in the region. It is separated by a major hiatus from the redefined Kim Fjelde Formation which includes mid-Permian (late Art­ inskian - Kungurian) carbonates and chert deposits. The Upper Carboniferous succes­ sion is dominated by cyclically interbedded siliciclastics and carbonates with minor tab- ular build-ups. The mid and Upper Permian succession consists ofcool-water carbonates, spiculitic chert and shales. L. S., S. pI & J. A.

NKA = Nunatta Katersugaasivia Allagaateqarfialu / Grønlands Nationalmuseum og Arkiv. Hermed fremsendes oversigt over de områder, som Grønlands Nationalmuseum og Arkiv anser for særligt beskyttelsesværdige. Arkæologiske lokaliteter i Nord- og Nordøstgrønland Særkendet ved Nationalparken er, at lovgivningen både beskytter hele den synlige forhistorie og de kultur- og naturlandskaber, som er skabt gennem årtusinder. I takt med forbedrede transport- og sikkerhedsteknologier vil interessen for at besøge fjerne, eksotiske områder stige. Det betyder, at der må tages særlige forhold i brug for at beskytte dette unikke, arktiske kulturlandskab. Kulturminder I betragtning af Grønlands størrelse er der kun få kulturminder; den begrænsede mængde er et produkt af en kort historie (4.400 år), de nomadiske livsformer og få personer i hver kulturperiode. I de eskimoiske kulturer er der generelt fokus på de samme ressourcer: sæl, hval, rensdyr, moskusokse og fugle og visse lokalitetstyper som polynia-områder, der ofte rummer særlige bopladser, som skal sikres, fordi de har stort forskningspotentiale, stort formidlingspotentiale og lign. Mange forskellige parametre medgår derfor ved udskillelsen af særligt sårbare områder I Nationalparken stiger mængden af fortidsminder fra Nord til Syd. Det store skift sker omkring 77°N (nordlige Germania Land). Nord for denne bredde-grad er de fleste kulturminder stærkt eksponerede, fordi der næsten ingen jordpålejring har været gennem 4.400 år - udover flyvesand.

    ARTICLE https://doi.org/10.1038/s43247-021-00197-5 OPEN Accelerated sea ice loss in the Wandel Sea points to a change in the Arctic’s Last Ice Area ✉ Axel J. Schweiger1 , Michael Steele1, Jinlun Zhang1, G. W. K. Moore 2,3 & Kristin L. Laidre1 The Arctic Ocean’s Wandel Sea is the easternmost sector of the Last Ice Area, where thick, old sea ice is expected to endure longer than elsewhere. Nevertheless, in August 2020 the area experienced record-low sea ice concentration. Here we use satellite data and sea ice model experiments to determine what caused this record sea ice minimum. In our simula- tions there was a multi-year sea-ice thinning trend due to climate change. Natural climate variability expressed as wind-forced ice advection and subsequent melt added to this trend. — — 1234567890():,; In spring 2020, the Wandel Sea had a mixture of both thin and unusual for recent years thick ice, but this thick ice was not sufficiently widespread to prevent the summer sea ice concentration minimum. With continued thinning, more frequent low summer sea ice events are expected. We suggest that the Last Ice Area, an important refuge for ice-dependent species, is less resilient to warming than previously thought. 1 Polar Science Center, Applied Physics Laboratory, University of Washington, Seattle, WA, USA. 2 Department of Physics, University of Toronto, Ontario, ON, ✉ Canada. 3 Department of Chemical and Physical Sciences, University of Toronto Mississauga, Mississauga, Ontario, ON, Canada. email: [email protected] COMMUNICATIONS EARTH & ENVIRONMENT
