A crossdisciplinary exploration of essentialism about kinds: philosophical perspectives in feminism and the philosophy of biology
DownloadFall 2011
“Essentialism about kinds” is the belief that there are necessary and sufficient conditions for membership in a kind. This thesis addresses the parallels in the discussions of essentialism across feminism and the philosophy of biology. Specifically, I address the similarities and differences...

Carotenoid diversity in novel Hymenobacter strains isolated from Victoria Upper Glacier, Antarctica, and implications for the evolution of microbial carotenoid biosynthesis
DownloadFall 2009
Many diverse microbes have been detected in or isolated from glaciers, including novel taxa exhibiting previously unrecognized physiological properties with significant biotechnological potential. Of 29 unique phylotypes isolated from Victoria Upper Glacier, Antarctica (VUG), 12 were related to...

Cascading of dense water from the shelf to deeper layers of the adjacent ocean basin has been observed in several locations around the world. The West Greenland Shelf (WGS), however, is a region where this process has never been documented. In this study, we use a numerical model with a 1/48...

Marson, Juliana M., Gillard, Laura C., Myers, Paul G.
While Greenland discharge has been increasing in the last decades, its impact on the Meridional Overturning Circulation (MOC) is not clearly established. Because of that, the accuracy of this discharge representation in ocean models has not been a priority in large-scale circulation studies. Many...

Extreme High Greenland Blocking Index Leads to the Reversal of Davis and Nares Strait Net Transport Toward the Arctic Ocean
Download2021-01-01
Myers, Paul G., de al Guardia, Laura Castro, Fu, Chuanshuai, Gillard, Laura C., Grivault, Nathan, Hu, Xianmin, Lee, Craig M., Moore, G. W. K., Pennelly, Clark, Ribergaard, Mads Hvid, Romanski, Joy
Baffin Bay exports Arctic Water to the North Atlantic while receiving northward flowing Atlantic Water. Warm Atlantic Water has impacted the retreat of tidewater glaciers draining the Greenland Ice Sheet. Periods of enhanced Atlantic Water transport into Baffin Bay have been observed, but the...

The goal of this guide is to derive a better understanding of the biodiversity of sponges across the eastern Canadian Arctic. Specimens were collected during research cruises aboard the Canadian Coast Guard Ship (CCGS) Amundsen in October 2015, July 2016 and July 2017. Collection sites were...

Greenland freshwater pathways in the sub-Arctic seas from model experiments with passive tracers
Download2016
Chassignet, Eric, Lee, Craig M., Bamber, Jonathan L., Curry, Beth, Dukhovskoy, Dmitry S., Timmermans, Mary-Louise, Platov, Gennady, Myers, Paul G., Proshutinsky, Andrey, Hu, Xianmin, Somavilla, Raquel
Accelerating since the early 1990s, the Greenland Ice Sheet mass loss exerts a significant impact on thermohaline processes in the sub-Arctic seas. Surplus freshwater discharge from Greenland since the 1990s, comparable in volume to the amount of freshwater present during the Great Salinity...

Natural kinds in evolution and systematics: metaphysical and epistemological considerations
Download2009
Despite the traditional focus on metaphysical issues in discussions of natural kinds in biology, epistemological considerations are at least as important. By revisiting the debate as to whether taxa are kinds or individuals, I argue that both accounts are metaphysically compatible, but that one...

Numerical modelling of the Arctic and North Atlantic exchanges with NEMO: Focus on freshwater and dynamics
DownloadFall 2018
The Arctic is currently undergoing significant changes due to increasing anthropogenic greenhouse gases causing atmospheric warming. The impact of this warming is clearly visible in the Arctic: reduced sea-ice cover, enhanced land-ice melting, increased frequency of extreme weather, etc....
