Describes the visit in 1965 by a Canadian party under A. Laing, Minister of Northern Affairs and National Resources; its itinerary included research institutions in Moscow and Leningrad, the Bratsk hydropower station, also Yakutsk and Noril'sk where the permafrost station construction projects were viewed. The Russian party under A. Slivinskii, Vice-Chairman of the State Building Committee subsequently visited Canada, going to Hay River, Inuvik, and other northern points of interest. Exchange of permafrost and building specialists is planned.
Lists, with detailed morphologic and taxonomic information, several species of these crustaceans collected 1948-1950 by various parties. The latter, working in the area described, with pertinent station data and species recovered. Some taxonomically significant variations are noted among the species listed, also some range extensions.
Marine platform of probable Sangamon age, and associated terrace deposits, Cape Thompson area, northwestern Alaska
Arctic, v. 18, no. 4, Dec. 1965, p. 230-245, ill., figures, map
ASTIS record 9968
Reports geomorphic studies, as part of the US Atomic Energy Commission's investigations in this area 1958-1962. A coastal terrace, observed and measured along a 20-mi section crossing Ogotoruk Creek, is described and its origin, age, and morphology discussed. The feature is complex, consisting of a marine platform planed across bedrock, overlying marine and beach deposits, and a depositional upper surface of nonmarine sediments which coincides in area and configuration with the platform, possibly as a result of factors unique to polar areas. The marine platform and gravels record the last high stand of sea level, 28-40 ft above the present, which occurred about 38,000 yr ago. Other evidence in the area indicates still higher seas in earlier times.
Discusses the use of photographs from spacecraft to determine various kinds of features, based on experiences with Nimbus I during Aug-Sept 1964. Advanced Vidicon Camera System photographs of sea and glacier ice in Canada, Greenland, and the Antarctic are shown; and the nature and quality of data yielded are considered. The striking pattern of sunlight and shadows resulting from low sun angle near the poles is noted, also a method for estimating heights of peaks, glacier slopes, etc from length of the shadows. Surface temperatures and snow and ice emissivities in the Antarctic were determined from High Resolution Infra-Red photographs.
The microbiology of some permafrost soils in the Mackenzie Valley, N.W.T.
Arctic, v. 18, no. 4, Dec. 1965, p. 256-260
Contribution - Canada. Soil Research Institute, no. 149
ASTIS record 9970
Reports on the microbial flora of soil samples obtained in northern Mackenzie District in July 1960. Large numbers of microorganisms were found, more in the tundra-boreal forest transition types than in the tundra, also more in uncultivated than in cultivated soils. Decrease in incubation temperature reduced the numbers of actinomycetes and bacteria in the tundra-boreal forest transition soils but less effect on those from tundra soils and on fungi numbers. Predominance of the various fungi genera isolated however was influenced by temperature.
Notes sighting in May-June 1965 of 87 species of birds; seven specified as not expected beyond the tree line. Nesting northern phalaropes were observed to have an egg-laying interval of 24-48 hr and no evidence of territorial behavior.
Relationship of white spruce to lenses of perennially frozen ground, Mount McKinley National Park, Alaska
Arctic, v. 18, no. 4, Dec. 1965, p. 262-267, ill., figure, table
ASTIS record 9972
Reports investigations of perennially frozen mounds beneath individual trees growing in silty clay on a terrace of the McKinley River. Climate, vegetation and parent material of the spruce stand are described. The mounds, 2-4 m in diam, contain a frozen lens-shaped core. The permafrost results from lower temperatures under the trees due to less snow cover and a thicker moss layer. A proposed cycle of development and collapse of the tree mounds is outlined.
The Icefield Ranges Research Project (IRRP) began its fifth research season 5 May 1965 when those people who were studying meteorology and climatology arrived in Whitehorse, Yukon Territory, for a two-day briefing under the direction of Mr. H. Wahl, Chief Forecaster for the Department of Transport weather station. Personnel involved in other research continued to Kluane Lake to open the base station and to begin checking and calibrating equipment and instruments. Kluane Station (870 m.) was fully operational by 10 May. The Kaskawulsh and Divide Stations (1730 m. and 2640 m.) were in operation by, respectively, 14 and 28 May. Seward Station (1850 m.) was opened 8 July for a three week intensive micro-meteorological study. Kaskawulsh terminus camp and three other satellite camps also were occupied during part of the summer. Personnel departed from Kluane Lake by Institute bus, carryall, and aircraft on 20 August. In the course of the 15-week research season there were 14 programs involving 47 people. Research included studies in glaciology, glacial hydrology, geophysics, dielectric measurements in snow and radio wave propagation, climatology and meteorology, geomorphology and glacial chronology, stream morphology, plant and animal ecology, and aerial photography and mapping. To support the field parties, over 300 hours were flown by the Arctic Institute's Helio Courier aircraft and over 300 landings were made on glaciers and unprepared surfaces. Among the members of the summer program were three Doctorate and three Master's degree candidates. IRRP was amplified in 1965 by a National Science Foundation program of Research Participation for College Teachers. Six teachers took part in a 10-week program in which they were given an opportunity to observe and assist in a number of activities within the broadest boundaries of their chosen field of science. As a consequence, three teacher participants have been awarded Academic Year Extension grants by the National Science Foundation to continue research in the St. Elias Mountains during 1966 and 1967. A research program in part logistically supported by IRRP and complementary to the IRRP hydrological traverse was undertaken by a five member team of scientists from the U. S. Army Cold Regions Research and Engineering Laboratory, Hanover, N.H. The project involved snow studies in vertical profile on the north side of Mount Logan to elevations in excess of 5400 m. ...
B. Frank Heintzleman, a Fellow of the Arctic Institute since 1955, died in Juneau, Alaska on 24 June, 1965. Mr. Heintzleman was an outstanding Alaskan and a leader in the development of the Territory for many years. After Alaska became a State, Mr. Heintzleman devoted most of his time to the encouragement and nurturing of its development possibilities. Frank Heintzleman was born in Fayetteville, Pennsylvania, in 1888. He was a forester and received his B.S. in Forestry from the Pennsylvania State College in 1907 and his M.F. from Yale in 1910. He was appointed the Regional Forester for Alaska in 1937 and held that position until 1953. During the same interval he was the Commissioner for Alaska of the Department of Agriculture. During World War II he directed the Alaska Spruce Log Program, a public agency formed to take Sitka spruce from Alaska forests for aircraft material. In 1953 he became the Governor of the Territory of Alaska, a position which he held until 1957. Alaska will miss Frank Heintzleman. His broad knowledge of the State, his long experience, his high principles and his dedication to the development of the State were invaluable.
