      <title>SATELLITE POSITIONING TECHNIQUES IN THE ARCTIC</title>
      <link>https://trid.trb.org/View/46260</link>
      <description><![CDATA[This paper describes TRANSIT Satellite Navigation Systems, installed on the Arctic ice pack in the spring of 1975. The systems supplied are measuring ice station separations over hundred kilometer baselines, to within a few meters and ice rotation to within plus or minus 2 degrees. To achieve this, several special techniques were implemented: automatic pass selection to optimize satellite tracking, time recovery to improve doppler counting and real time translocation for rapid evaluation of azimuth and strain parameters.]]></description>

      <title>ARCTIC BIBLIOGRAPHY, VOLUME 16</title>
      <link>https://trid.trb.org/View/33813</link>
      <description><![CDATA[This sixteenth volume of the ARCTIC BIBLIOGRAPHY gathers together carefully selected information on the high latitudes of the world, and comprises titles and English abstracts of books and papers published in some 40 languages.  It fills a need for authoritative reference material on the polar and sub-polar regions of the world. Using the resources of the principal libraries of Canada and the United States, as well as those of specialized collections from abroad, it covers all pertinent fields of science and technology, as well as of the arts.  It has become the standard reference work on all aspects of northern research and development, not only for major libraries and research institutions but for individual scholars, industry and government.  A valuable compilation of information on low-temperature phenomena, it is generally recognized as the most comprehensive regional bibliography ever assembled.]]></description>

      <title>AGS PUBLISHES MAP OF THE ARCTIC</title>
      <link>https://trid.trb.org/View/36008</link>
      <description><![CDATA[A 1:5,000,000 map of the Arctic was published by the American Geographical Society (AGS) in September 1975. Among other information, the map includes limits of trees, permafrost, and sea ice, locations of major research stations, archaeological sites, and active weather stations. A glossary lists abbreviations used in the geographical names and gives meanings of commonly used terms in the foreign names.  The bathymetric data for the map were supplied by Bruce Heezen of the Lamont-Doherty Geological Observatory.  O.M. Miller provided the scale departure diagram and the information on measuring areas and distances on the map.  Under a joint program with the U.S. Geological Survey, the Society used the LANDSAT (formerly called Earth Resources Technology Satellite) imagery in preparing the map, the first map of the Arctic to incorporate satellite data for adjusting topographic features.  The map is reproduced in 10 colors and measures 127 by 152 centimeters. The map price is $12 prepaid, which includes postage and handling.  Folded and unfolded copies are available in the United States; folded copies only are available outside the United States.  (No further information in article).]]></description>

      <title>ARCTIC AND SUBARCTIC ENVIRONMENTAL ANALYSES UTILIZING ERTS-1 IMAGERY</title>
      <link>https://trid.trb.org/View/37749</link>
      <description><![CDATA[The author has identified the following significant results. ERTS-1 imagery provides a means of distinguishing and monitoring estuarine surface water circulation patterns and changes in the relative sediment load of discharging rivers on a regional basis.  Physical boundaries mapped from ERTS-1 imagery in combination with ground truth obtained from existing small scale maps and other sources resulted in improved and more detailed maps of permafrost terrain and vegetation for the same area.  Snow-pack cover within a research watershed has been analyzed and compared to ground data.  Large river icings along the proposed Alaska pipeline route from Prudhoe Bay to the Brooks Range have been monitored.  Sea ice deformation and drift northeast of Point Barrow, Alaska have been measured during a four day period in March and shore-fast ice accumulation and ablation along the west coast of Alaska have been maped for the spring and early summer seasons.]]></description>

      <title>FIVE-YEAR COORDINATED PLAN FOR ARCTIC RESEARCH</title>
      <link>https://trid.trb.org/View/13938</link>
      <description><![CDATA[The Interagency Arctic Research Coordinating Committee has conducted an updating and revision of the Five-Year Coordinated Plan for Arctic Research, orginally published in February 1972.  This plan describes the programs of the member agencies of the IARCC.  There are areas of research where interagency coordination is not yet adequate as data is not always available.  Much of the material used in this document was assembled over an extended time period.  Thus, by the time this document is published some of the planned projects will have been completed, modified, or abandoned. Many sections of this document have historical connotations. Procedures are being established that will lessen this problem and place emphasis on plans for future research as originally intended.  A separate study is planned that will identify research gaps and overlaps in the Five-Year Plan and consider research areas requiring priority attention. Funds expended for logistic support of arctic research, shown in the funding tables, constitute a significant expense.  The Arctic presents unique physical problems which must be overcome before large projects can be conducted safely and efficiently.  Without the identification of these associated costs, the funding tables would fail to provide an accurate estimate of the expenditures.  However, because it has been difficult to separate the cost of support from that of research, the estimates given indicate merely the order of magnitude of the logistic costs.  The budget figures projected in the plan are estimates and do not imply any commitment for future funding on the part of any agency.]]></description>

      <title>ARCTIC ICE DYNAMICS JOINT EXPERIMENT. 1972 AIDJEX PILOT STUDY</title>
      <link>https://trid.trb.org/View/10117</link>
      <description><![CDATA[AIDJEX Bulletin No. 14 is devoted to a preliminary review of the 1972 AIDJEX pilot study, which was held during March-April 1972 on pack ice in the Beaufort Sea approximately 500 km north of Pt. Barrow, Alaska.  The Bulletin contains a description of the general operation, followed by a series of project summaries written to give a rough inventory of the data collected. The last section consists of position, weather, and azimuth data for all camps (main camp and two satellite camps).]]></description>

      <title>DEPENDENCE OF THE MEAN THICKNESS OF FAST ICE ON HUMMOCKING</title>
      <link>https://trid.trb.org/View/9000</link>
      <description><![CDATA[Ice thickness is one of the basic indices which characterize the ice cover of the Arctic seas.  Therefore, a great deal of work has been devoted to the study of the laws governing its change in dependence upon hydrometeorological conditions.  In the majority of the investigations, however, the thicknesses of level ice -- which in the Arctic seas is encountered rather rarely -- are examined.  The situation hampers the use of empirical or analytical methods for determining ice thickness concurrent with different degrees of hummocking.  If the influences of hummocking is not taken into account, then the calculated values of the ice thicknesses can differ considerably from the actual.  As shown by numerous observations taken in fast ice, an increase of ice hummocking results in an increase of its thickness not only in the zone of the hummocks, but also in the comparatively level areas situated among the hummocks. At the same time the ice thickness was measured, visual observations were made on the ice hummocking in the vicinity of the measurements, and the results of these observations were fixed on film simultaneously with the recording of the thickness.]]></description>

      <title>ARCTIC ICE DYNAMICS JOINT EXPERIMENT-BULLETIN NO. 15--AIDJEX SCIENTIFIC PLAN</title>
      <link>https://trid.trb.org/View/9192</link>
      <description><![CDATA[Bulletin No. 15 is devoted exclusively to the AIDJEX Scientific Plan.  An operations and logistics plan for the main experiment will appear in a later Bulletin.  An understanding of the large-scale response of sea ice to its environment is needed for solving many important theoretical and practical problems, ranging from the interaction between ice cover and global circulation to the passage of ships in ice-covered seas.  It is proposed to conduct measurements from an array of drifting stations in the Arctic Ocean.  The measurement programs at the stations will define all the forces acting on the ice and the resulting motion and deformation of the ice pack.  The data from the proposed experiment should yield new results on the rheology of sea ice and on the interactions between the Arctic Ocean, the sea ice, and the atmosphere.  A series of pilot studies is now in progress.  The main experiment is scheduled to begin in the spring of 1975, and to last for about one year.]]></description>

      <title>ARCTIC ICE DYNAMICS JOINT EXPERIMENT-BULLETIN NO. 16--INVESTIGATION OF THE ICE CONDITIONS IN THE ARCTIC SEAS AND METHODS OF FORECASTING AND COMPUTATION</title>
      <link>https://trid.trb.org/View/9193</link>
      <description><![CDATA[The collection of papers which comprise Volume 303 of the Proceedings (Trudy) of the Arctic and Antarctic Scientific Research Institute in Leningrad covers a wide range of topics related to the ice conditions in the Arctic seas. According to the editor's Perface, it is intended for oceanologists and graduate students of hydrometeorological specialization.  Because of the length of the translation, the volume is printed in two halves.  The first half, AIDJEX Bulletin No. 16, contains one group of papers which deal with the variations of ice coverage and methods of computation and forecasting, and another group addressing problems related to ice drift.  The second half of Volume 303, AIDJEX Bulletin No. 17, covers (1) formation and deterioration of the ice cover and (2) methodological topics connected with the study of the parameters and deformation of the ice cover.]]></description>

      <title>ON THE WATER OF TUKTOYAKTUK HARBOUR</title>
      <link>https://trid.trb.org/View/8468</link>
      <description><![CDATA[Describes major features of the 1962-63 temperature and salinity data collected from the ice cover and aboard M/V Richardson in Kugmallit Bay and Tuktoyaktuk harbor in eastern Mackenzie Delta in connection with the operation of an airbubbler system.  A rough winter energy budget of the water with and without an ice cover is given, water exchange between the bay and harbor due to summer estuarine and winter tidal mechanisms is suggested, and the significance of conditions in the seaward approach discussed.  During the summer season ice and snow melt and runoff, an estuarine type of circulation occurs, comprising a seaward flow of a mixed fresh and salt water surface layer and a compensating subsurface salt water flow into the harbor.  With an ice cover, a tidal effect brings freshwater from the bay into the harbor to increase the depth of a freshwater layer and to decrease the salinity at depth below an intense halocline.]]></description>
