Report 825 Series

The Report 825 series includes the results of the research that was done during the International Geophysical Year, 1957-1958. Following the field work, the personnel involved in this phase of IGY research assembled on the campus of The Ohio State University where office facilities were made available for the data reduction and analysis. The resulting publications, the report 825 series, were primarily data reports that were published by The Ohio State University Research Foundation and were distributed by the American Geographical Society. This series was terminated in 1961 with the publication of the last of the IGY reports.

Report 968 Series

The Report 968 series includes the results of research that was done during the follow-up to the IGY, the International Geophysical Cooperation (IGC), 1959. The results were also published by The Ohio State University Research Foundation, but were distributed by the Institute of Polar Studies, which had been formally established in February 1960 as an outgrowth of the IGY-IGC research. This series also was terminated in 1961 with the publication of the IGC reports.

Institute of Polar Studies Report Series

Early in 1962, the Institute began a new series referred to as the Institute of Polar Studies Report series. The purpose of this series is to publish the results of research which are too lengthy or detailed for standard journal articles and to serve as an outlet for preliminary results of research. This report series concluded with Report 87. There are some gaps in this report series because not every report was published.

Byrd Polar Research Center Report Series

The Institute of Polar Studies at The Ohio State University officially changed its name in 1987 to the Byrd Polar Research Center. The report series name was changed to reflect the new name of the Center. The Byrd Polar Research Center Report Series started with Report number 1 and is still published, although not on a regular basis.

Glaciology, Victoria Land Traverse, 1959-60
(Research Foundation, The Ohio State University, 1961-01) Stuart, Alfred W.; Heine, Arnold J.
The interpretation of 19 snow pits dug by the 1959-60 Victoria Land Traverse gives a mean annual accumulation of 16 cm of water equivalent for the area studied. Deposition is thought to occur in the form of sastrugi instead of in blanket form and this introduces a serious error in the interpretation. Approximate mean annual air temperatures ranged between -38.4°c and -47.4°c. A map of the traverse route shows contoured elevations and sastrugi observations. The highest elevation was 2591 meters. A compilation of accumulation stakes emplaced by this traverse is made available. The Rennick Glacier which empties into Rennick Bay and extends southward for about 300 kilometers was reconnoitered by the traverse party; a sketch map is included. Accumulation stakes were measured on the Ross Ice Shelf, Skelton Glacier, and the Victoria Land Plateau near the coast of the Ross Sea. Annual values ranged from 23.5 cm to 1.7 cm of water equivalent; the higher accumulation is on the Ross Ice Shelf.
Studies in the Geochronology and Geochemistry of the Transantarctic Mountains
(Research Foundation, The Ohio State University, 1970-09) Faure, Gunter; Eastin, R.; Gunner, J.; Hill, R. L.; Jones, Lois M.; Elliot, David H.
This is the third annual progress report submitted by Institute of Polar Studies researchers to the National Science Foundation (Grant No. GA-898X) on the geochronology and geochemistry of rocks from the Transantarctic Mountains, Antarctica. The results reported in this report are preliminary in nature.
Geomorphology and Pedology of Amchitka Island: Final Report
(Research Foundation, The Ohio State University, 1969-09) Everett, Kaye R.
Amchitka Island is composed of volcanic rocks and minor amounts of sandstones, conglomerates and glacial deposits, all of relatively recent geologic age. Most of these rocks are fractured and faulted. The island has undergone a series of upward and downward movements relative to sea level. Much of the present topography of the island has been conditioned by its past positions relative to sea level, as well as by glacial and near-glacial climatic conditions. Geomorphologically the island can be separated into six more or less distinct segments. The three eastern segments are characterized by upland areas with numerous shallow lakes and ponds with little or no drainage connection. On both the north and south sides of the upland the land surface is dissected into low hills. The drainage between ponds may be both via surface and subsurface routes. The streams reach the sea across an elevated marine platform after exiting through deep “V”-shaped valleys. With the exception of the shallow organic cover of the easternmost segment, this area is covered with 20 to 40 inches or more of organic soil. Seven distinct soil types have been identified on the basis of their drainage, moisture content, character of peat, particle size distribution of underlying mineral soil, position in the landscape and natural stability. Their field relationships are presented on five map sheets which accompany this report. These soil groups have been mapped in detail at small scale and form the basis for predictions as to their behavior under testing and construction activities. The soil characterizations provide a basis on which the biological programs, particularly vegetation and pond ecology studies, can draw for community distribution and pond chemistry.
Glaciological Investigations on the Casement Glacier, Southeast Alaska
(Research Foundation and the Institute of Polar Studies, The Ohio State University, 1970-09) Peterson, Donald N.
Measurements made on Casement Glacier during the summers of 1965, 1966, and 1967 revealed time-variations in the horizontal component of the surface velocities. The summer velocities were greater than the “winter” velocities. The magnitude of the summer velocities varied from year to year, but was always greater than the winter velocity. These changes in surface velocity correspond to changes in the basal sliding velocity as measured in an ice tunnel along the margin of the glacier. Discharge and budget measurements were calculated for two sections of the glacier. The mass budget of each section was negative. Englacial velocities were calculated at each of the stakes for which the ice thickness had been determined by gravity and the surface velocity by surveying. Using these velocity data, the vertical components of the surface velocity, the longitudinal ice thickness profile, the trajectory of a layer of ice was calculated from line 14 through line 2. The estimated travel-time for this motion would be approximately 140 years. Two short-term heat-balance studies, of four days duration each, were conducted on the glacier in 1967. The contribution of each component of the heat balance equation was computed, first, using the assumption that the variation of the wind speed, temperature, and vapor pressure follows the power law, and later, recalculated assuming a logarithmic variation. The calculated results were compared with the observed values of the ablation during the corresponding periods. The values determined by the power law fit the observed ablation data better than those calculated from the logarithmic law. Investigations were made in an ice tunnel on the variations in slip rate and the mechanics of basal sliding. Basal sliding at the point of observation in the tunnel was a continuous process; there was no jerky, stick- slip movement and any observed jerky movement on the surface probably resulted from fracture and shearing of the surface ice. The rate of sliding is affected by changes in the quantity of lubricating water at the bed and most of the observed annual, seasonal, and diurnal changes in surface velocity result from changes in the quantity of free water at the bed of the glacier. Artificial obstacles were placed on a bedrock knob and the mode of flow of ice around them examined. It was determined that the critical size at which the contribution of regelation slip equals that of plastic flow is between 1 and 2.5 cm.
Glacial Geology of the Burroughs Glacier Area, Southeastern Alaska
(Research Foundation and the Institute of Polar Studies, The Ohio State University, 1971-08) Mickelson, David M.
Burroughs Glacier is a sprawling, stagnating remnant of a much larger Neoglacial ice mass in Glacier Bay National Monument. In 1892, when the earliest photographs were taken of it, an ice plateau 10 km by 25 km was present. Since that time the ice surface has downwasted as much as 750 m and its calving margin has retreated 27 km. The ice mass separated into the Burroughs Glacier with its margin on land and Plateau Glacier with its terminus at sea level. Between 1960 and 1970 ice surface lowering averaged 9.5 m/yr at 205 m elevation (in 1960) to 4.6 m/yr at 440 m elevation (in 1960). Retreat of the land-based ice front was up to 140 m/yr and of the calving ice margin up to 350 m/yr during this time. During deglaciation, the ice-flow direction changed because of the emergence of hills. Vertical sections of till show changes in lithology and fabric direction with depth. Because the rate of change of ice-flow direction is known the rate of till deposition has been calculated. Rates at seven localities on stoss and lee sides of nunataks range from 0.4 cm/yr to 2.8 cm/yr. Most till deposition took place after 1890 except on the stoss side of nunataks where thick till has been deposited. Hilltop striations were cut until just before the hills emerged. Moraine ridges up to 2 m high have been squeezed into crevasses from below near the calving Plateau Glacier margin. Within the ridges, till fabric diagrams have modes with azimuths that are not necessarily perpendicular to the ridges but are parallel to the horizontal component of the last ice-flow direction. With the emergence of nunataks near the southeastern Burroughs terminus, small, stagnant bodies of ice were left in the lee of nunataks. Here sand and gravel eskers up to 100 m long and 4 m high and with sharp crests head at the break in slope between the valley wall and valley bottom. In one case they were deposited between 1959 and 1960 by streams flowing at the base of the ice in the same direction as the ice surface gradient. Another esker, composed of laminated silt and sand at its downstream end, was deposited between 1965 and 1967 in a closed tube under hydrostatic pressure. In some cases water flowing around nunataks did not flow under the ice but flowed along the ice margin depositing kame terraces, or into the ice leaving a hummocky blanket of sand and gravel on the till. Three ice-dammed lakes were present at the southeast terminus of Burroughs Glacier at times between 1941 and 1960. Sand and silt up to 2 m thick remain, but distinct shorelines were not formed. Meltwater flowing directly from the glacier has deposited outwash both on and off ice. The major stream began depositing outwash between 1941 and 1948. By 1970 outwash at the 1948 margin position had been incised about 23 m. During this interval the ice withdrew about 1300 m up the valley. Outwash deposited on ice between about 1956 and 1964 had collapsed by 1970. Water flowing from the ice has cut marginal channels in till to depths of 20 m. Sets of three and four large channels were occupied 10 to 15 years. Smaller marginal channels, 1-2 m deep, were cut along the stoss sides of several hills. At least 8 successively lower channels up to 100 m in length were formed in one year. The gradients of these channels reflect the ice margin gradient.
Glacial Geology and Late Cenozoic History of the Transantarctic Mountains, Antarctica
(Research Foundation and the Institute of Polar Studies, The Ohio State University, 1975-11) Mayewski, Paul A.
A glacial geology for the Transantarctic Mountains is determined, based on a comparison of glacial deposits in the Queen Maud Mountains and along the nunataks at the heads of the ice-free valleys of southern Victoria Land with deposits studied by other workers in southern Victoria Land. The deposit used to define the Queen Maud Glaciation is the Sirius Formation which is composed of two members: (1) lodgement till and (2) stratified ice-contact deposits. This formation is distinguished and interpreted by the investigation of the elevation of outcrop, underlying striae and grooves, structure, fabric of elongate clasts, particle size distribution, lithologic and mineralogic components, and rounding and freshness of contained clasts. Fluvial features including channels and potholes are used as evidence of the "interglacial" period which followed the Queen Maud Glaciation. These features represent far more extensive amounts of meltwater than are presently noted in the Transantarctic Mountains during even the height of the ablation season. The Scott, Shackleton and Amundsen Glaciations are differentiated by three sets of lateral moraines which can be traced throughout the Transantarctic Mountains. These moraines are named from oldest to youngest: High, Middle and Low Moraines. They are distinguished by the investigation of the elevation and continuity relative to present ice surface, morphology, thickness of drift, presence or lack of an ice core, and weathering of surficial clasts. In addition, several characteristics of the soils developed in these moraines are also used: particle size distribution, color, secondary salt content, acidity - alkalinity, and clay mineral content. Ice surface reconstructions are developed for the former glaciations recorded in the Transantarctic Mountains. These reconstructions are generated from a study of the distribution of the glacial deposits used to determine the glacial chronology since these deposits record former ice levels in the Transantarctic Mountains. The ice surfaces of former glaciations in these mountains are extrapolated inland to generate former ice sheet surface profiles and out onto the Ross Ice Shelf to determine former grounding lines and ice thicknesses in this area. The ice surface reconstructions indicate that during the Queen Maud Glaciation the Transantarctic Mountains were almost completely covered by ice. The East Antarctic sheet was as much as 350 meters thicker in the area of the present ice divide . A grounding line in the Ross Sea area extended 225 kilometers north of the present terminus of the Ross Ice Shelf. During the "interglacial" period which followed the Queen Maud Glaciation, the Antarctic ice sheet shrank to possibly less than its present dimensions. Three readvances follow this interglacial corresponding to the Scott, Shackleton and Amundsen Glaciation. Each readvance is marked by progressively less ice cover over the Transantarctic Mountains. The elevation of the ice sheet at the ice divide probably never exceeded 100 meters more than the present elevation during these glaciations. Grounding lines in the Ross Ice Shelf area were situated closer to the coast during each successive glaciation, finally resulting in the present, or Amundsen Glaciation grounding line . Ice volumes are determined from the ice surface profiles of the former glaciations. These ice volumes are extrapolated over the area of Antarctic grounded ice and ice shelves, assuming the Transantarctic Mountains reflect glacial events over the whole continent. The ice volumes are converted to sea level equivalents to determine the effect of Antarctic glaciations on worldwide sea level.
Stratigraphy and Petrology of the Mainly Fluviatile Permian and Triassic Beacon Rocks, Beardmore Glacier Area, Antarctica
(Research Foundation and the Institute of Polar Studies, The Ohio State University, 1969-08) Barrett, Peter J.
The near horizontal Beacon strata (Devonian?-Triassic) of the Beardmore Glacier area rest on a peneplain cut mainly in a Precambrian to Lower Paleozoic graywacke and phyllite sequence intruded by granitic plutons. The 2600-m-thick Beacon sequence comprises eight formations; the Alexandra Formation (Devonian?), the Pagoda, Mackellar, Fairchild and Buckley Formations (Permian), the Fremouw and Falla Formations (Triassic), and the Triassic?-Jurassic Prebble Formation. The Ferrar Group (Jurassic), which overlies and intrudes the Beacon rocks, comprises the Kirkpatrick Basalt and Ferrar Dolerite. This study is concerned mainly with the stratigraphy and petrology of the Permian and Triassic Beacon strata above the glacial Pagoda Formation. The Mackellar Formation, which conformably overlies the Pagoda Formation, consists of 60 to 140 m of laminated medium- to dark-gray shale and light-gray fine-grained sandstone, but the proportion of sandstone increases to the northwest. Current flow was southeasterly. The formation was deposited in a quiet body of water extending for 1000 km along the Transantarctic Mountains from the Queen Elizabeth Range to the Ohio Range; Sr87/Sr86 ratios suggest a nonmarine environment. The Fairchild Formation consists of 130 to 220 m of arkosic sandstone deposited by southeast-flowing streams. The sand was derived from a granitic and metasedimentary source, though same may have been reworked glacial debris. The Buckley Formation is a crudely cyclic coal-bearing sequence about 750 m thick; sandstone beds rest on erosion surfaces and grade upward into carbonaceous shale. Coal forms as much as six percent of the section. Leaves (mainly Glossopteris) and stems are common. Buckley sandstone had two nonvolcanic sources; quartz - plagioclase K-feldspar sand from the west, and quartz-plagioclase sand from the north. Intermediate-acid volcanic detritus appears 100-300 m above the base of the formation and dominates the sandstones in the upper part. The Triassic Fremouw Formation consists of three parts: the lowest is a 100-m-thick cyclic sequence of quartzose sandstone and greenish-gray siltstone; the middle, 200 m thick, is mainly siltstone and includes sandstone with volcanic fragments; the upper 300 m is mainly similar volcanic sandstone, although the beds become carbonaceous toward the top. A labyrinthodont jawbone fragment was discovered near the base of the formation, and leaves of Dicroidium and logs were found near the top; root impressions occur throughout. The Falla Formation, which is from 160 to 530 m thick, is a cyclic sandstone-shale sequence in the lower part. The sandstone is more quartzose than that below, but it is diluted progressively up the section by volcanic material. The upper part of the formation is dominated by vitric tuff. Accretionary lapilli suggest at least one volcanic center within the Queen Alexandra Range. The Fremouw and Falla Formations were deposited on a flood plain with streams flowing to the northwest, in contrast to the southeast-flowing Permian streams. The Prebble Formation, from 0 to at least 460 m thick includes laharic deposits, agglomerate and tuff, and is overlain by Kirkpatrick Basalt. Several diabase sills, normally from 50 to 200 m thick, intrude the strata between the Pagoda and Falla Formations. Metamorphism by the sills has resulted, in the Buckley and Fremouw Formations, in locally extensive laumontite replacement of plagioclase, volcanic grains and matrix in the volcanic sandstones. Replacement minerals in the Falla and Prebble Formations include clinoptilolite, analcime and mordenite. A few sandstones in the Buckley and Fremouw Formations contain prehnite and grossularite.
Petrography of Metamorphic Rocks from the Miller Range, Antarctica
(Research Foundation and the Institute of Polar Studies, The Ohio State University, 1969-08) Gunner, John D.
Rock samples collected from the metamorphic rocks of the Nimrod Group in the Miller Range, Antarctica, comprise six lithological groups: mica schists, metaquartzites, banded gneisses, augen gneisses, marbles and amphibolites. Mineral parageneses indicate that these rocks have been regionally metamorphosed to the lower almandine-amphibolite facies of the Barrovian facies series. Chemical analyses calculated from petrographic modes of 13 representative thin sections indicate that the amphibolites were derived from basaltic rocks, but that the principal sources for the remaining five lithologies were sedimentary.
A First Look at NGRIP Surface Climatology (1997-2001) Using Automatic Weather Station Data
(Byrd Polar Research Center, The Ohio State University, 2002) Box, Jason E.
Greenland ice sheet automatic weather station (AWS) data provide high temporal resolution climate information for NGRIP (75.09980° N, 42.3326° W. 2918 m), where a tremendously long ice core climate record is becoming available. In this paper, an overview is made or the surface climatology or NGRIP to support work on ice core interpretation using GRIP meteorological observations and snow pits. Valuable perspective is given by comparison of NGRIP climate with other deep ice core sites (Summit and Camp Century), where AWS data are also available.

(Research Foundation, The Ohio State University, 1972-01) Gunner, John; Bowman, John R.; Faure, Gunter
This is the fourth annual progress report submitted by Institute of Polar Studies researchers to the National Science Foundation (Grant No. GA-898X) on the geochronology and geochemistry of rocks from the Transantarctic Mountains, Antarctica. The results reported in this report are preliminary in nature.
Geochronology of the Transantarctic Mountains
(Research Foundation, The Ohio State University, 1968-05)
This volume is the first annual progress report submitted by Institute of Polar Studies researchers and graduate students to the National Science Foundation (Grant No. GA-898X) on the geochronology of the Transantarctic Mountains. As this is the first report submitted, the conclusions embodied in this report are based in many instances on incomplete data and are therefore to be regarded as tentative. This progress report contains eight individual papers.
The Isotope Composition of Strontium and Cation Concentrations of Lake Vanda and Lake Bonney in Southern Victoria Land, Antarctica
(Research Foundation, The Ohio State University, 1969-06) Jones, Lois M.; Faure, Gunter
The ice-free valleys of southern Victoria Land are located in the Transantarctic Mountains west of Ross Island, Antarctica. In these valleys, the average annual temperature is well below the freezing point of water and precipitation is extremely low. Nevertheless, lakes are present and soils have begun to form since deglaciation. These lakes and soils are characterized by high concentrations of salts. The salinity of some lakes, such as Lake Vanda and Don Juan Pond in Wright Valley and Lake Bonney in Taylor Valley, is several times greater than that of sea water. In addition, salts occur as surface efflorescences and as lenses and cement within the soil. The origin of the salts in the lakes and soils of the ice- free valleys is controversial. Possible sources that have been suggested include: (l) trapped sea water; (2) wind-transported marine salts; (3) volcanic activity and associated hot springs; and (4) chemical weathering of local soil and bedrock. Previous attempts to explain the origin of the salts have resulted in conflicting conclusions because the parameters which were used (chemical composition, isotope composition of the water) have been modified by chemical or physical processes occurring in the lakes. In order to determine the origins of the salts, a new parameter is needed that can unambiguously identify a specific source for the salts. The isotopic composition of strontium in the salts meets the necessary requirements because: (1) the isotopic composition of strontium of each of the possible sources is distinctive and differs significantly from that of the other sources, and (2) the isotopes of strontium are not measurably fractionated in natural processes such as are occurring in the ice- free valleys. The objective of this study was to ascertain the usefulness of strontium isotopes as natural tracers, and to identify thereby the source(s) of the salts in the lakes and soils of the ice-free valleys in Antarctica. Lakes Vanda and Bonney were studied in detail because they are the largest and most unusual of the Antarctica lakes. Both lakes are perennially ice-covered and are meromictic. At depth the water is highly saline and has surprisingly high temperatures. Lake Vanda has a maximum density of 1.10 g/ml at a depth of 67 m, and a maximum recorded temperature of +28°C at the bottom of the lake. Lake Bonney has a maximum density of 1.20 g/ml at a depth of 32 m, and reaches a temperature of +8°C at about the middle of the depth profile. In order to determine the origin of the salts in the two lakes, measurements were made of the isotopic composition of strontium in water samples collected at different depths from the surface to the bottom of the lakes. The results of these analyses were then compared to isotopic compositions of strontium in sea water, basalts of the McMurdo volcanic province, and the strontium in water-soluble salts from the soils in Wright and Taylor Valleys. From these comparisons the principal sources of the strontium in the two lakes can be clearly identified. In addition to measurements of the isotopic composition of strontium in the lakes, chemical analyses of the brines have been made to provide information that can be used with the isotopic studies to develop a model for the geochemical evolution of the lakes. The combination of isotopic and chemical analyses of the brines in Lakes Vanda and Bonney permits the formulation of a better model than has been possible before.

Microclimatological, Pedological, and Geomorphological Studies in the Western Tasersiaq Area, Greenland During Summer 1964
(Research Foundation, The Ohio State University, 1965-11) Everett, Kaye R.; Holowaychuk, N.; Loewe, F.; Kryger, A.
During the summer 1964, personnel of The Ohio State University Institute of Polar Studies conducted a field program in the Sukkertoppen Ice Cap area of southwest Greenland. The program included studies of soil and mass wasting in the Tasersiaq area immediately east of the ice cap, and studies of the microclimatology across the eastern edge of the ice cap. The results of this research program are contained in four parts. Part I, by Adolph Kryger, discusses the microclimatological (excluding radiation) results of observations taken at four stations, one at the base of the slope below the eastern edge of the Sukkertoppen Ice Cap, two intermediate ones on the slope, and one at the edge of the glacier. Part II, by Fritz Loewe, discusses the radiation observations. Both have related their observations to those at other permanent stations along the western Greenland coast. Part III, by K. R. Everett, presents the results of studies of mass-wasting and patterned ground phenomena. Part IV, by N. Holowaychuk and K. R. Everett, contains most of the results of the pedological studies. The report herein includes the discussion of soil morphology,chemistry, and classification.
Mapping Glaciers in Western United States
(Research Foundation, The Ohio State University, 1962-01) Brandenberger, Arthur J.
The subject of this research is the preparation of photogrammetric maps of the Burroughs Glacier in Alaska, the Dinwoody Glacier in Wyoming, and the Palisade Glacier in California. These maps were compiled in the scale 1 : 5000 with a contour interval of five meters, according to specifications established for the IGY Project 4.11.
The Use of Photogrammetric Methods to Investigate Surface Movement of the Antarctic Ice Sheet
(Research Foundation, The Ohio State University, 1964-09) Weissman, Simha
This report represents a part of a study being made to measure the surface movement of the Antarctic ice sheet using photogrammetric methods. The area under investigation is between Byrd Station and Mt. Chapman. Markers were placed in this area along a distance of 365 km and their positions were determined by aerial triangulation. One hundred twenty eight models were bridged and the coordinates obtained will be compared with future observations i n order to determine the rate of movement of the ice sheet. This report evaluates the work accomplished in the field, explains the performance of the aerial triangulation, analyzes the accuracy obtained and suggests a proposal for future work in view of the experience gained.
