The year’s publications: a review with listing for 2000 Peter R. Dawes Chief Editor This review deals with just one part of the Survey’s total publication production for the year 2000, namely, that covering geoscientific topics about Greenland, the surrounding oceans and neighbouring lands, i.e. Canada, Svalbard and Iceland. Publications about Denmark, the Faeroe Islands, and other regions of Scandinavia, as well as elsewhere in the world where the Survey has been active, are listed on the Survey’s website (www.geus.dk). Following a summary of the year’s achievements, this review lists the publications released in 2000 in the Survey’s own series, as well as the scientific and semipopular articles written by staff and co-workers published in external outlets. International volumes on Greenland and related areas, where staff have acted as scientific editors or compilers, are also cited. Geoscientific abstracts on Greenland, of which about 50 were published during the year, as well as other forms of information transfer (e.g. international symposia, seminars, conferences, posters, etc.) are not listed but may be consulted in the annual publication catalogue that is on the Geological Survey of Denmark and Greenland (GEUS) website. All available products are listed in the Catalogue of Greenland publications and data described below (Fig. 1). The present coverage of Greenland by standard geological maps at scales 1:500 000 and 1:100 000, as well as Quaternary geology and geophysical maps, is shown in the index maps of Fig. 2. The range of products now available on CD-ROM, and released in 2000, is illustrated in Fig. 3 while facsimiles of 2000 covers from four Greenland-relevant publication series are shown in Fig. 4. Summary of the year’s achievements The Survey’s status as a research and advisory institution under the Ministry of Environment and Energy carries a commitment to achieve specific objectives that are outlined and defined in contract periods. The year 2000 was the first year of the new contract period 2000–2003. An assessment in 1999 of the research and publications record of several departments at the Survey (specifically oil- and gas-related research) by an international evaluation panel led to a recommendation for more emphasis on the release of research results in international peer-reviewed publications. Rather than represent a fundamental change in publication strategy, the panel’s report (Danmarks og Grønlands Geologiske Undersøgelse Rapport 1999/69) calls for a shift in research culture to encourage more staff to publish, or to be involved in the preparation of, high-quality external publications, thus helping to promote the Survey’s international profile. In the short life of the present Survey (established in 1995 by the fusion of the former Geological Survey of Denmark and the former Geological Survey of Greenland), the number of scientific research products each year has been dominated by titles released in international outlets. Peer-review bulletins and maps in the Survey’s own series have formed only a small part of the total annual publication achievement and this also applies for the year 2000. The Survey’s field operations in Greenland in 2000 and the associated activities in Copenhagen, including those of the Danish Lithosphere Centre (administratively attached to GEUS), resulted in about 50 scientific papers on Greenland and surrounding regions being released in external publication outlets. In addition, three special volumes on Greenland and neighbouring regions published by international journals were edited/compiled by Survey staff. Maps. The national geological map sheet coverage of Greenland has two scales: 1:500 000 and 1:100 000. The 1:500 000 series that was initiated in the 1970s is nearing completion (see Fig. 2A); the 1:100 000 map series, the first map sheet of which was published in 1967, has a sporadic coverage with the main map-sheet blocks in West, South-West, South and East Greenland Geology of Greenland Survey Bulletin 189, 11–23 (2001) © GEUS, 2001 11
(see Fig. 2B). One map sheet from each series was printed in 2000. The publication of the Lambert Land map sheet from North-East Greenland brought the total of 1:500 000 maps released up to 12, leaving just two sheets outstanding. The publication of the map sheet Uiffaq, from the Disko Bugt region of central West Greenland, brings the total of 1:100 000 maps printed up to 55. The high-resolution, airborne geophysical mapping of West Greenland south of 71ºN that was initiated in the early 1990s was completed with a survey in 1999 of the region between 65º40′N and 68º20′N (see Fig. 2D, for magnetic and electromagnetic coverage). In 2000, a total of 62 maps from the 1999 survey were released: two at a scale of 1:250 000 with the remainder at 1:50 000. Parameters available are total magnetic intensity and associated vertical derivatives. Digital products. The demand for digital versions of all types of geoscientific data is increasing and the Survey is meeting this challenge by releasing soft copies of maps and data on CD-ROM (Fig. 3), as well as improving electronic access to databanks with the aim of delivering information through the internet. In 2000, nine CD-ROMs were issued; some of these comprise compilations of existing data and maps, while others contain new data and refined datasets and images. CD-ROMs designed to give exploration companies easy access to digital multi-datasets were released from onshore South Greenland (mineral potential) and offshore southern West Greenland (hydrocarbon potential). The South Greenland CD-ROM, that focused on the mineral resource potential of the Palaeoproterozoic Ketilidian mobile belt, contains the hitherto most comprehensive digital assembly of geoscientific data available from a particular region of Greenland, with geological, geophysical, geochemical, topographical, mineral occurrences and remote sensing spatial datasets (see page 15 under CD-ROM issues). The West Greenland CD-ROM, specially prepared to highlight the geology and hydrocarbon potential of the offshore region between 63º and 68ºN, contains a wide range of geoscientific data, including play types and information on licensing policy and operational conditions. In the Geology of Denmark and Greenland Map Series, seven CD-ROMs were released featuring previously published 1:100 000 geological maps bringing the total of digital versions of standard map sheets up to 15 (eight CD- ROMs with geological maps at 1:500 000 have been released previously). Of the 2000 issues, six relate to the Archaean craton of southern West Greenland, and one is from the Palaeoproterozoic Ketilidian mobile belt of South-East Greenland. Bulletins. Four volumes of the Survey’s peer-reviewed series – Geology of Greenland Survey Bulletin – were published in 2000. These included the long-awaited descriptive text to the 1:2 500 000 Geological map of Greenland (Bulletin 185); the map sheet itself was printed and released in 1995. A folded copy of the map is included with the bulletin. The map is also available as an individual sheet (96 × 120 cm) supplied in a map roll; an atlas (20 × 24 cm) presenting the map in 12 parts is in preparation. The effort to have the annual Review of Greenland activities (Bulletin 186 covering 1999 activities) to the public earlier than usual succeeded with printing in early July 2000. This publication, produced in full colour and with a wide distribution to libraries and the Survey’s geological contacts, continues to be the Survey’s most popular international publication. The review was followed by a multi-article volume (Bulletin 187) dealing with the sedimentary evolution of the Wandel Sea Basin in North Greenland based on new field work and palynological studies (of some relevance to the hydrocarbon potential of the immediate offshore region), and a volume (Bulletin 188) on the regional tectonic features of the late Phanerozoic rocks of Svartenhuk Halvø, central West Greenland, the origin of which is related to the opening of Baffin Bay. Ph.D. theses and Reports. The Survey fosters close cooperation with Danish universities and research institutions, and one aspect of this cooperation is the training of students by research scientists and research professors for higher degrees. Five theses on Greenlandrelated subjects were submitted in 2000 by students based at the Survey as part of Ph.D. degrees at the Universities of Copenhagen and Aarhus. Two of these appeared in the Danmarks og Grønlands Geologiske Undersøgelse Rapport series (numbers 2000/64 and 2000/82). In 2000, this open file-type series released 19 reports with a Greenland geological content. Most Greenland-related reports in this series are in English but a few have Danish titles; several reports were issued with data attached in CD-ROM or diskette form. International newsletters. The two newsletters to international industry – Ghexis Newsletter and Greenland MINEX News – continue to gain readership. They are published jointly by GEUS and the Bureau of Minerals and Petroleum (BMP), Government of Greenland, and both newsletters are now available on the websites of both institutions (www.geus.dk and www.bmp.gl; see page 23 under Availability of Survey publications). In 2000 there were three issues: numbers 17 and 18 of Ghexis Newsletter and number 18 of Greenland MINEX News. 12
