Redox-sensitive partitioning of vanadium and other heterovalent elements between apatite and biotite in high silica magmas
Apatite and biotite, ubiquitous minerals in a multitude of natural rocks, host a variety of trace elements, including those whose valence state, and hence ionic radius and charge, can vary over the oxygen fugacity (fO2) ... -
Mid-Pliocene warm-period deposits in the High Arctic yield insight into camel evolution
The mid-Pliocene was a global warm period, preceding the onset of Quaternary glaciations. Here we use cosmogenic nuclide dating to show that a fossiliferous terrestrial deposit that includes subfossil trees and the ... -
Beating the heat: Development and evaluation of a Canadian hot weather health-response plan
An increasing number of cities subject to hazardous summer weather in the United States and Canada have began to develop and implement hot weather response plans to prevent heat-related illnesses and deaths. In this study ... -

Nature Appropriation and Associations with Population Health in Canada's Largest Cities
Earth is a finite system with a limited supply of resources. As the human population grows, so does the appropriation of Earth's natural capital, thereby exacerbating environmental concerns such as biodiversity loss, ... -
Development of a wearable global positioning system for place and health research
Background: An increasing number of studies suggest that characteristics of context, or the attributes of the places within which we live, work and socialize, are associated with variations in health-related behaviours and ... -
Sources of nutrients to windward agricultural systems in pre-contact Hawai'i
Prior to European contact in 1778, Hawaiians developed intensive irrigated pondfield agricultural systems in windward Kohala, Hawai'i. We evaluated three potential sources of nutrients to windward systems that could have ... -
Paleo-sea ice conditions of the Amundsen Gulf, Canadian Arctic Archipelago: Implications from the foraminiferal record of the last 200 years
Four boxcores were collected as part of the Canadian Arctic Exchange Shelf Study (CASES) in the Amundsen Gulf at water depths of 59 m to 600 m. Data from these cores help to develop a record of changes in the oceanographic ... -
Messinian deep-water turbidites and glacioeustatic sea-level changes in the North Atlantic: Linkage to the Mediterranean Salinity Crisis
Our benthic foraminiferal data clearly indicate eight layers of deepwater turbidites during the Messinian (MTL 1-8) and one in the early Pliocene (PTL 1) in Ocean Drilling Program Leg 105, Site 646B. These deep-water ... -
Stable isotopic composition of deep-sea gorgonian corals Primnoa spp.: a new archive of surface processes
The deep-sea gorgonian coral Primnoa spp. live in the Atlantic and Pacific Oceans at depths of 65 to 3200 m. They have an arborescent growth form with a skeletal axis composed of annual rings made from calcite and gorgonin. ... -
Radiocarbon evidence for annual growth rings in the deep-sea octocoral Primnoa resedaeformis
The deep-sea gorgonian octocoral Primnoa resedaeformis is distributed throughout the Atlantic and Pacific Oceans at depths of 65 to 3200 m. It has a 2-part skeleton of calcite and gorgonin. Towards the inside of the axial ... -
Foraminiferal assemblage changes over the last 15,000 years on the Mackenzie-Beaufort Sea Slope and Amundsen Gulf, Canada: Implications for past sea ice conditions
Two cores, one from the Beaufort Sea Slope at 1000 m water depth (core 750) and one from the Amundsen Gulf at 426 m (core 124), were collected to help determine paleo-ice cover in the Holocene and late glacial of this area. ... -
Crooked-line 2D seismic reflection imaging in crystalline terrains: Part 2, migration
Seismic reflection surveys are frequently conducted over very complicated geological structure, but surveying often must be confined to existing crooked roads or tracks. Typically, data from such 2D crooked-line surveys ... -
Crooked-line 2D seismic reflection imaging in crystalline terrains: Part 1, data processing
For cost and access reasons, most of the seismic reflection data collected in crystalline terrains have been acquired by 2D crooked-line profiling. When the survey geometry is significantly irregular and the geologic ... -
2D waveform tomography applied to long-streamer MCS data from the Scotian Slope
Detailed velocity models of the earth's subsurface can be obtained through waveform tomography. The accuracy of the long-wavelength component of such velocity models, which is the background velocity field, is particularly ... -
