Temporal and environmental significance of microbial lamination: insights from Recent fluvial stromatolites in the River Piedra, Spain.
Download2017-01-01
Despite extensive research, the environmental and temporal significance of microbial lamination is still ambiguous because of the complexity of the parameters that control its development. A 13 year monitored record of modern fast‐accreting calcite stromatolites (mean 14 mm year−1) from...

In 2008 New Zealand (NZ) changed from a Labour-led to a National-led Government, and this resulted in a shift to Government’s carbon emission mitigation strategy, including the abandonment of the Communities for Climate Protection and the Carbon Neutral Public Service programs. Using deLeon’s...

The aftermath of Petermann Glacier calving events (2008-2012): Ice island size distributions and meltwater dispersal.
Download2018-01-01
Crawford, Anna J., Mueller, Derek, Desjardins, Luc, Myers, Paul G.
Three large calving events occurred at Petermann Glacier in northwest Greenland between 2008 and 2012 that generated ice islands (large tabular icebergs) that ranged from ~30 to 300 km2 in areal extent. Ice islands are known to deteriorate, via fracture and melt, during their drift through...

The aluminum-in-olivine thermometer for mantle peridotites — Experimental versus empirical calibration and potential applications
Download2017-02-01
E. Jackson, Simon E., Bussweiler, Yannick, Hardman, Matthew, Stern, Richard A., Brey, Gerhard Peter, Kjarsgaard, B.A., Pearson, Graham, Stachel, Thomas
This study provides an experimental calibration of the empirical Al-in-olivine thermometer for mantle peridotites proposed by De Hoog et al. (2010). We report Al concentrations measured by secondary ion mass spectrometry (SIMS) in olivines produced in the original high-pressure, high-temperature,...

The Atlantic meridional overturning circulation (AMOC) represents the zonally integrated stream function of meridional volume transport in the Atlantic Basin. The AMOC plays an important role in transporting heat meridionally in the climate system. Observations suggest a heat transport by the...

The evolution of calcite-bearing kimberlites by melt-rock reaction: evidence from polymineralic inclusions within clinopyroxene and garnet megacrysts from Lac de Gras kimberlites, Canada
Download2016-07-01
Luth, R. W., Stone, Rebecca, Menzies, Andrew, Bussweiler, Yannick, Pearson, Graham, Stachel, Thomas, Kjarsgaard, B. A.
Megacrystic (>1 cm) clinopyroxene (Cr-diopside) and garnet (Cr-pyrope) xenocrysts within kimberlites from Lac de Gras (Northwest Territories, Canada) contain fully crystallized melt inclusions. These ‘polymineralic inclusions’ have previously been interpreted to form by necking down of melts at...

The influence of high-frequency atmospheric forcing on the circulation and deep convection of the Labrador Sea
Download2015
Holdsworth, Amber M., Myers, Paul G.
The influence of high-frequency atmospheric forcing on the circulation of the North Atlantic Ocean with emphasis on the deep convection of the Labrador Sea was investigated by comparing simulations of a coupled ocean–ice model with hourly atmospheric data to simulations in which the...

The long-wave infrared (8-12 μm) spectral features of selected rare earth element –bearing carbonate, phosphate and silicate minerals
Download2022-03-01
Laakso, K., Turner, D.J., Rivard, B., Sánchez-Azofeifa, A.
Rare earth elements (REEs) are a group of metals essential to high technology industries. This high demand, combined with a high supply risk, has led to an understanding that REEs are critical to society. Despite the potential that hyperspectral imaging (HSI) data offers for a fast and...

The reflectance spectra of opal-A (05-22 µm) from the Taupo Volcanic Zone: spectra that may identify hydrothermal systems on planetary systems
Download2004-01-01
Goryniuk, Michelle C., Rivard, Benoit A., Jones, Brian
Opal‐A, the main component of siliceous sinters in many terrestrial hydrothermal systems, is a hydrated silicate that commonly incorporates silicified microorganisms. The detection of opal‐A on the surface of Mars, therefore, may carry important implications in the search for extraterrestrial...

Historically, governmental responses to homelessness in Canada have defaulted to the most basic of services such as food and shelter. Even under exceptional circumstances, such as the current coronavirus pandemic, governments still demonstrate reluctance to guarantee permanent, adequate and...
