Project: Quaternary Paleoenvironments as Proxies in Global Change
Funding Agency: NSERC Research Grant (1998-present); Field support provided
by Geological Survey of Canada (1994-present)
Ongoing studies reveal complexities of Earth's climate system. Realities of global warming (and cooling) affect all people. Quality of life is strongly allied to economic productivity, environmental health, and population dynamics, and each are affected by or adapt to climate changes.
To develop more robust models of climate change, and to better predict amplitude and frequency of climatic changes, it is necessary to develop a better understanding of the Earth’s present past climate. Milankovitch cycles alone (changes in the Earth’s orbital parameters) are not sufficient to explain observed glacial/interglacial cycles. Instead, positive feedbacks in climate system (vegetation/albedo/CO2/sea ice, snow cover) can be considered as non linear amplifiers of the external forcing mechanism (Milankovitch cycles).
Glaciation and deglaciation of Canada rank amongst the most extreme and fundamental climatic events. Investigations of northern and western regions of Canada reveal extensive suites of sediments containing paleoclimatic proxies extending back 3.0 million years (late Neogene Period). Proxies are indirect temperature and precipitation records established from fossil pollen, plant, animal and soil materials contained in sediments, as well as from preserved records of physical processes: periglacial features such as ice wedges, cryoturbation and patterned ground features, and Xerothermic features such as ventifacts, crusts, desiccation cracks, dunes, loess, drift soils, etc. Sediments from these regions occur in climate zones that are particularly sensitive to global warming and cooling. It is in these areas in particular that release of CO2 through melting of permafrost, and changes in vegetation, and snow and ice cover may provide strong global feedback.
Sedimentary records span a wide spectrum of time scales, ranging from decades to millions of years and are expressed with varying powers of resolution. A longstanding issue is use of proxy data is correlation of terrestrial and marine records. Each have been developed under very different conditions, and in many cases independent of one another. Nevertheless, each contains valuable information that can assist in the interpretation of the other. Magnetostratigraphy affords the best opportunity to correlate sedimentary and fossil records from these two environments, largely because reversals of the Earth’s magnetic field are essentially synchronous over the surface of the earth and are independent of the type of sedimentary facies in which the record is held.
My recent work in northern and western Canada and USA has identified polarity which span the Gauss, Matuyama and Brunhes polarity Chrons. From this sequence strategy maps have been produced which depict extent and duration of multiple glaciations in North America during late Neogene. From this work we see that distribution continental ice in the first 2 Ma was quite different from that of the last 0.7 Ma and this suggests that the factors which led to the growth and decay of ice sheets varied considerably. A better understanding of the relative importance of Keewatin versus Labrador-centered ice, and the role of the Arctic/North at their margins may also help explain overall ice distribution.
Ongoing research will focus: (1) in areas which contain suitable sediments but have not yet been studied in detail paleomagnetically (ie. Level Mtn, and Mt. Edziza B.C., Horton Plateau, NWT, Canadian Prairies, and southern margins of Laurentide ice in Washington, Oregon, Montana, and North Dakota). New magnetostratigraphies will better constrain timing and extent of ice sheets. Particularly important are paleomagnetic measurements of glacial tills and outwash (direct evidence of glaciation), and paleosols which develop during ice-free periods. (2) The magnetic “finger-printing” of preglacial, glacial, and non-glacial sediments in gold and diamond producing areas can provide valuable information about provenance, age, mode of deposition, and relationship to ice margins, explaining why some deposits contain placers and others not. (3) In the past 4 years paleosecular records from rythmites deposited by glacial outburst floods in Montana and Washington, have been developed. Here magnetostratigraphy provides a means to assess length of time over which deposits were laid down, and a better understanding of the dynamics of deglaciation. (4) To determine whether the Geocentric Axial Dipole Field of the Earth averages to the axis of rotation (a question of theoretical importance in paleomagnetism), a group of researchers including myself are currently sampling young basalts (<5.0 Ma) in 10o latitude intervals.
Anticipated Research Activity
Funding: NSERC; ULRF
(1) Robust (readable and relatively complete)
records which correlate well with ocean core data, have been derived
from the loess deposits of North America and central Asia. These deposits
are for the most part, located well beyond the limits of glaciation. To
assess the glaciated regions themselves, suitable outcrops have been located
in the Horton River area, NWT, Baffin Island, NWT, NW B.C., central and
southern Yukon, northern and southern Manitoba, and at several sites in
Alaska. The above mentioned sites are currently under scrutiny by researchers
from a number of disciplines. Collaborative research amongst federal, provincial,
industry, and university scientists have started what hopefully will become
a detailed and interdisciplinary assessment of the Canadian terrestrial record,
and afford an opportunity to make direct comparisons with the more complete
(2) Sampling will continue in the central
and southern Yukon, and in NW Alaska, along the Yukon/Tanana Rivers. These
projects will involve scientists from the Geological Survey of Canada,
the US Geological Survey, and will continue a large project initiated in
1995, to map the glacial limits in the Yukon, and determine the
origin of the gold-bearing gravels there. We have shown (Froese,
Barendregt, Hein, Smith, 1997; Duk-Rodkin, Barendregt, White and
Singhroy, 2001) that magnetic "finger-printing" of fines contained within
the gravels, combined with lithologic determinations of the gravels themselves,
allows for a reconstruction of terrace chronosequences, flow directions,
and provenance. This is of value in determining why some gravels are gold-bearing
and others are not, and may provide an effective tool for the mining industry
in assessing the gold-bearing potential of yet undeveloped gravel deposits.
(3) Coring and Magnetostratigraphy of
Wascana Creek Tephra Site This study is being carried out to determine
the relationship of the dated Wascana Tephra bed (450 ka) to the overlying
and underlying deposits. It provides one of the few absolute dates obtained
from Quaternary sediments on the Canada prairies. This is a collaborative
project between the University of Lethbridge, University of Saskatchewan, and Saskatchewan Highways Department.
Anticipated Significance of the above
Because reversals of the Earth's magnetic
field are essentially synchronous over the surface of the earth, and are
independent of the type of sedimentary facies in which the record is held,
the measurement of geomagnetic field variations in sediments and rocks
can be effectively used in assessing the passage of time. In preglacial
as well as early to middle Pleistocene sediments where 14C dating
cannot be carried out, and where few other dating techniques are available,
often affords the only dating tool. Assigning sediments and rocks to
polarity chrons and subchrons provides an opportunity to relate the more
detailed (but often fragmentary) record of terrestrial/glacial sequences
to orbital and insolation cycles, and to Milankovich forcing in which the
coupled air-sea-ice system acts as a non-linear amplifier (Imbrie et al.
The increased geographic coverage of
sites within northern, Cordilleran, and prairie climatic zones of Canada
will provide a better understanding of the spatial and temporal aspects
of bio-climatic-geomorphic systems. Within a local or regional content,
correlations can be made between outcrops and bore-core data, between adjacent
study sites, and between on and offshore records. The comparison of present
and past responses to global warming and cooling, based on proxy, as well
as historic records, will provide workers with a more accurate assessment
of the amplitude and frequency of variations that might reasonably be expected
to occur in the near as well as distant future. Determining the resolving
power of past climatic records will enhance the reliability of short-term
global change modelling, and ultimately facilitate the predicting of climate
variability over centuries and decades.

2005 “ The earliest humans in northern Europe:
artefacts from the Cromer Forest-bed Formation at Pakefield, Suffolk,
UK” Nature (in press).
The colonization of Eurasia by early humans is a key event following their spread out of Africa, but the timing of the earliest human occupation in northwest Europe is uncertain and has been the subject of intense debate. The southern Caucasus were occupied about 1.8 Ma and Spain and Italy about 800 ka, all before the Brunhes-Matuyama reversal, while the earliest uncontested artefacts from northern Europe indicate colonization after 500 ka. Interglacial deposits containing what are thought to be the earliest artefacts in northern Europe have now been dated using paleomagnetism, amino acid racemization and biostratigraphy, and indicate an early Brunhes age (ca 700 ka). Paleomagnetism combined with absolute and relative dating methods is here, as elsewhere, shown to be a valuable dating tool.

Late Cenozoic Ice Sheets in North America: A magnetostratigraphic
Assessment” in Quaternary Glaciations-Extent and Chronology,
Part II, editors, J. Ehlers and P.L. Gibbard. Quaternary Science
Reviews. Elsevier, p. 1-7.
Our understanding of the extent and timing of major ice-sheet development in North America, has until recently remained uncertain. With the more widespread use of magnetostratigraphy, and detailed mapping of surficial deposits, it has become possible to delineate the approximate spatial and temporal extent of some ice sheets. This summary paper provides a magnetostratigraphic assessment of what is known for North America.

A detailed magnetostratigraphic assessment of 21 locations in NW Canada has for the first time permitted a crude mapping of glacial extent of Cordilleran/montane and continental glaciations. Successive Cordilleran glaciations diminished in size, while continental glaciations increased. Moisture sources for the Cordilleran ice was largely the Pacific Ocean, while for the northern interior an open Arctic may have been a significant moisture source. The role of tectonics (Wrangell/St Elias and macKenzie/Selwyn Mtns.) appears to have been an important controlling variable in moisture distribution in NW Canada and east-central Alaska. Timing and interplay of uplift versus erosion of these barriers has very much controlled the growth, thickness and decay of ice masses in the interior of the Yukon and valleys east of the continental divide.

2004 “Glacial Stratigraphy and Paleomagnetism of
late Cenozoic deposits of the north-central United States” Geological
Association of America Bulletin v. 116, no.1 / 2, p. 30-41.
The north-central US preserves one of the best continental records of late Pliocene and early-middle Pleistocene glaciations in the Northern Hemisphere. The chronology is constrained by paleomagnetism and 3 volcanic ashes. The oldest till was deposited before 2.0 Ma but during the Matuyama Reversed Chron. Three groups of tills have been identified, representing at least 7 pre-Illinoian glaciations: two older groups of reverse polarity containing low and intermediate proportions of crystalline clasts, respectively, and one younger group of normal polarity tills enriched in crystalline lithologies. These lithological characteristics as well as clay mineralogy suggest an increase with time in the areal distribution of unweathered igneous and metamorphic source bedrock (a result of successive unroofing of the saprolite mantle of the Canadian Shield by ice sheet erosion), each successive glaciation exposing a greater surface area of fresh crystalline rocks.

of Missoula floods in southern Washington”. Geology. March 2003; v. 31, no. 3, p. 247-250 (plus data repository item 2003023).
Unequivocal evidence that the glacial outburst floods along the southern margin of the Laurentide ice sheet in Montana, Idaho and Washington States occurred repeatedly (at least tens of floods) is based on paleomagnetic and tephra evidence. The several thousand year secular variation record compares well with paleomagnetic data from Fish Lake, Oregon and Mono Lake, California, for the interval 12,000-17,000 14C yr. B.P. The previous suggestion that a single flood was responsible for these deposits can be ruled out.

2001 "Geologic evolution of the Yukon River:
implications for placer gold", Quaternary International (in press)
Placer gold potential in the west-central Yukon is
associated with aggradation of rivers following extensional faulting in
the Tintina Trench area, differential uplift, and regional denudation.
New drainages were formed as a result of glacial diversion, and the Yukon
River itself was changed from south flowing to north flowing. Based
on paleomagnetism, stratigraphy, gravel lithologies, and palynology, these
changes occurred in the pre-late Miocene, early Pliocene, and late Pliocene.

Evidence that the earliest glaciations in the Yukon
extend into the Pliocene, is based on paleomagnetism and tephra dates.

This work provides a summary of 20 years of magnetostratigraphic
study and assigns Canadian glacial/interglacial events to the polarity
timescale, and to the isotopic record from deep-sea cores. Based on these

This study provides a detailed record of Quaternary environments
in the N.W. Canadian Arctic, based on paleomagnetism, and suggests that
there is no evidence for glaciation in the N.W. Arctic until after the
Olduvai (1.77 Ma). This implies that the earlier continental glaciations
were not as extensive as the latter ones, and may suggest that the Arctic
ocean behaved quite differently during the Early Matuyama than during the

and tectonic events in the eastern Andes of Colombia", Quaternary Research.
V. 47, p. 1-14.
Magnetostratigraphy, combined with detailed pollen records from 4
sites (located within an enclosed basin), provides the most complete equatorial
terrrestrial paleoclimate record to date. As in North America, Cordilleran
glaciations are first recorded in the late Gauss, and a shift to higher
magnitude oscillations is seen after the Brunhes/Matuyama boundary (0.78
The above studies (i-x) highlight the value of magnetostratigraphy
in providing chronological control for sediments deposited during the preglacial
as well as the early to middle Pleistocene period, a time when few of the
available dating techniques can be applied. Furthermore, magnetostratigraphy
allows correlation between terrestrial and deep-sea records, and provides
an opportunity to relate the more detailed (but often fragmentary) record
of terrestrial glacial/interglacial sequences to orbital and insolation
cycles, and to Milankovitch forcing in which the coupled air-sea-ice system
acts as a nonlinear amplifier (Opdyke, 1993; Imbrie et al. 1993).
Above results are used in an 18 Ma record of climate and
vegetation change in northwestern Canada and Alaska depicting tectonic
and global climatic correlates (J.M. White et. al 1997).
