Abstract Notes made by land surveyors in 1858 were utilized to estimate cover of grasses and shrubs on the Jornada Experimental Range (JER) and the Chihuahuan Desert Range Research Center (CDRRC) in… Expand
Marine Molluscs as Indicators of Environmental Change in Glaciated North America and Greenland During the Last 18 000 Years
- A. Dyke, J. Dale, R. McNeely

- 30 November 2007
Dated mollusc collections are classified in assemblages to map paleo-faunistic zones. Hiatella arctica and Mya truncata account for almost half the records and comprise a restricted arctic… Expand
A high resolution proxy-climate record from an arctic lake with annually-laminated sediments on Devon Island, Nunavut, Canada
- K. Gajewski, P. Hamilton, R. McNeely
- Geology
- 1 February 1997
Sediments from a 3 ha lake (75 °34.34′N, 89 °18.55′W) from the coastal region of northern Devon Island, Nunavut, Canada, contain discrete laminations in the deepest part of the basin. The laminations… Expand

Abstract Varved (annually-laminated) sediments offer a rare and physically undisturbed archive of past trace metal deposition and limnological conditions. Here, a high-resolution 1,300 year record of… Expand
Teeth as biomonitors of soft tissue mercury concentrations in beluga, Delphinapterus leucas
- P. Outridge, Rudolph Wagemann, R. McNeely
- Biology
- 1 June 2000
This paper reports relationships between bulk Hg concentrations in the tooth cementum and soft tissues of free-living beluga (Delphinapterus leucas). Total Hg levels were determined in slivers of… Expand
The calculation of lead-210 dates for McKay Lake sediments
- S. Joshi, B. S. Shukla, R. McNeely
- Geology
- 1 December 1988
Lead-210 dates are assigned to a sediment core retrieved from McKay Lake, Ottawa, Canada. Sediment mixing is found to have little, but discernible, influence on the age/depth profile. Consideration… Expand
