A high-resolution (up to 2 km), unstructured-grid, fully coupled Arctic sea ice-ocean Finite-Volume Community Ocean Model (AO-FVCOM) was employed to simulate the flow and transport through the Canadian Arctic Archipelago (CAA) over the period 1978–2013. The model-simulated CAA outflow flux was in reasonable agreement with the flux estimated based on measurements across Davis Strait, Nares Strait, Lancaster Sound, and Jones Sounds. The model was capable of reproducing the observed interannual variability in Davis Strait and Lancaster Sound. The simulated CAA outflow transport was highly correlated with the along-strait and cross-strait sea surface height (SSH) difference. Compared with the wind forcing, the sea level pressure (SLP) played a dominant role in establishing the SSH difference and the correlation of the CAA outflow with the cross-strait SSH difference can be explained by a simple geostrophic balance. The change in the simulated CAA outflow transport through Davis Strait showed a negative correlation with the net flux through Fram Strait. This correlation was related to the variation of the spatial distribution and intensity of the slope current over the Beaufort Sea and Greenland shelves. The different basin-scale surface forcings can increase the model uncertainty in the CAA outflow flux up to 15%. The daily adjustment of the model elevation to the satellite-derived SSH in the North Atlantic region outside Fram Strait could produce a larger North Atlantic inflow through west Svalbard and weaken the outflow from the Arctic Ocean through east Greenland.

Multiple tracers demonstrate distinct sources of dissolved organic matter to lakes of the Mackenzie Delta, western Canadian Arctic Tank, Suzanne E.; Lesack, Lance F. W.; Gareis, Jolie A. L.; Osburn, Christopher L.; Hesslein, Ray H. (Association for the Sciences of Limnology and Oceanography, 2011-07)Lakes of the Mackenzie Delta occur across a gradient that contains three clear end members: those that remain connected to river-water channels throughout the summer; those that receive only brief inputs of river water ...
Evidence of molting and the function of “rock-nosing” behavior in bowhead whales in the eastern Canadian Arctic Fortune, Sarah M. E.; Koski, William R.; Higdon, Jeff W.; Trites, Andrew W.; Baumgartner, Mark F.; Ferguson, Steven H. (Public Library of Science, 2017-11-22)Bowhead whales (Balaena mysticetus) have a nearly circumpolar distribution, and occasionally occupy warmer shallow coastal areas during summertime that may facilitate molting. However, relatively little is known about the ...
Reproductive morphology of three species of deep-water precious corals from the Hawaiian Archipelago : Gerardia Sp., Corallium secundum, and Corallium lauuense Waller, Rhian G.; Baco, Amy R. (University of Miami - Rosenstiel School of Marine and Atmospheric Science, 2007-11-01)Three species of deep-sea corals were collected from several locations in the Hawaiian Archipelago. These species have been called "precious corals" because of their extensive use in the jewelry industry. Two octocorals ...
