Harden, J.W., Payne, N., Friedli, H.R., Radke, L.F., Crock, J., Flannigan, M.D., Turetsky, M.R.
With climate change rapidly affecting northern forests and wetlands, mercury reserves once protected in cold, wet soils are being exposed to burning, likely triggering large releases of mercury to the atmosphere. We quantify organic soil mercury stocks and burn areas across western, boreal Canada...

Charged particle behavior in the growth and damping stages of ultralow frequency waves: Theory and Van Allen Probes observations
Download2016
Wygant, John R., Zong, Qui-Gang, Kletzing, Craig A., Blake, J. Bernard, Kivelson, Margaret G., Zhou, Xuzhi, Chen, Xing-Ran, Rankin, Robert, Wang, Zi-Han
Ultralow frequency (ULF) electromagnetic waves in Earth's magnetosphere can accelerate charged particles via a process called drift resonance. In the conventional drift resonance theory, a default assumption is that the wave growth rate is time independent, positive, and extremely small. However,...

Shear Alfvén waves on stretched magnetic field lines near midnight in Earth's magnetosphere
Download2000
Tikhonchuk, Vladimir T., Rankin, Robert, Fenrich, Frances
The spectrum of toroidal standing shear Alfvén waves (SAWs) is derived for a stretched magnetic field line geometry that is approximated by the Tsyganenko 96 magnetic field model. The model is applied to field lines near the midnight meridional plane. It is demonstrated that the fundamental mode...

Tikhonchuk, V. T., Voronkov, I., Samson, J. C., Rankin, Robert
A model is presented that describes the excitation of density perturbations and parallel electric fields by standing shear Alfven waves on dipole fields in Earth's magnetosphere. The model includes the effects of electron inertia and gyro-kinetic dispersion, accounting for field-aligned...

Electrodynamics of magnetosphere‐ionosphere coupling and feedback on magnetospheric field line resonances
Download2007
Marchand, Richard, Lu, J. Y., Rankin, Robert, Solomon, Stanley C., Wang, Wenbin, Lei, J., Rae, I. Johnathan
We present a new dynamic model that describes coupling between standing inertial or ion-acoustic-gyroradius-scale shear Alfven waves, compressional modes, and auroral density disturbances. The model is applied to the excitation of field line resonances (FLRs) in dipolar and stretched geomagnetic...

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....

Structure and dynamics of biomolecules: probing muscle regulation, prion protein unfolding, and drug insertion into DNA by nuclear magnetic resonance spectroscopy
DownloadSpring 2011
Nuclear magnetic resonance (NMR) spectroscopy is a powerful approach to study the structure and dynamics of macromolecules in a close-to-native solution environment. In the present thesis I present my investigation of protein and nucleic acid structure and dynamics in a wide variety of biological...

Spring 2023
Switchable hydrophilicity solvents (SHSs) are solvents defined by their ability to switch from their hydrophobic form to a hydrophilic form when put in contact with an acidic trigger such as CO2. As a consequence, SHSs qualify as promising alternatives to volatile organic compounds during the...

Field line resonances in a stretched magnetotail: CANOPUS optical and magnetometer observationsournal of Geophysical Research: Space Physics, 107(A7), [pp
Download2002
Tikhonchuk, V. T. , Wanliss, J. A., Rankin, Robert, Samson, J. C.
Ground-based observations support the existence of 1-4 mHz field line resonances (FLRs) at auroral latitudes. The low frequencies suggest that many nightside FLRs are excited on stretched magnetic field lines in the inner plasma sheet. Data from the Canadian Auroral Network for the OPEN Program...

Comparison of the open‐closed separatrix in a global magnetospheric simulation with observations: The role of the ring current
Download2010
Kabin, Konstantin, Lu, J. Y., Rankin, Robert, Gombosi, Tamas I., Watt, Clare E. J., Ridley, Aaron J., Toth, Gabor, Milan, Steve E., Zhang, Jichun, Rae, I. Johnathan, Clauer, C. Robert, De Zeeuw, Darren L., Fenrich, Frances
The development of global magnetospheric models, such as Space Weather Modeling Framework (SWMF), which can accurately reproduce and track space weather processes has high practical utility. We present an interval on 5 June 1998, where the location of the polar cap boundary, or open-closed field...
