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...

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...

Sea ice thickness evolution within the Canadian Arctic Archipelago (CAA) is of great interest to science, as well as local communities and their economy. In this study, based on the NEMO numerical framework including the LIM2 sea ice module, simulations at both 1/4 and 1/12◦ horizontal resolution...

Climate change is among the most critical challenges facing local government decision-makers in the north. Yet while risk is clear, with climate impacts occurring there more rapidly than many regions on Earth, integrated policy and planning for climate adaptation often remains a low priority for...

Icebergs represent approximately half of Greenland’s yearly mass loss, having important implications for biological productivity, freshwater fluxes in the ocean, and navigation. This study applies an iceberg model that uses integrated ocean fields (from surface to iceberg keel) to simulate the...

Dmitrenko, Igor A., Kirillov, Sergei A., Rudels, Bert, Babb, David G., Myers, Paul G., Stedmon, Colin A., Bendtsen, Jorgen, Ehn, Jens K., Pedersen, Leif Toudal, Rysgaard, Soren, Barber, David G.

A portion of the freshwater transport through Fram Strait consists of low-salinity Pacific-derived Arctic water flowing southward along the east coast of Greenland. The pathways of this water are currently unclear. An Ice Tethered Profiler deployed over the southeastern Wandel Sea shelf...

Vermetid buildups, formed primarily of Dendropoma, are found in the coastal areas near Bodden Town and Great Bluff Estates on Grand Cayman. These gastropods are commonly encrusted by foraminifera (Homotrema rubum, Acervulina? sp.), coralline algae, and cyanobacteria. Spaces between the gastropods...

We experimentally investigate the behaviour of a line-source plume falling through a finite two-layer stratified ambient where the depth of the upper ambient layer increases in time. Laboratory observations suggest one of two possible flow regimes depending on the value of 𝜆 , which represents...

Two stretches of rocky coastline on Grand Cayman are characterized by boulders that are up to 5.5 m long, 3.4 m wide, and 2.3 m high (estimated to weigh as much as 40 tonnes). Clusters of boulders, which are irregularly distributed through the area, occur up to 100 m inland from the present-day...
