Biogeochemical cycling of nutrient silicon in a human-impacted large lake nearshore environment (Hamilton Harbour Area of Concern, Lake Ontario, Canada)
(University of Waterloo, 2017-12-14)The biogeochemical cycling of nutrient silicon (Si) through rivers, wetlands, lakes, and artificial reservoirs regulates the magnitude and bioavailability of Si delivered downstream and to the ocean (Frings et al. 2014; ... -
Influence of a dammed reservoir on nutrient (N, P, Si) loads and ratios of the Thames River, Ontario
(University of Waterloo, 2021-01-20)The increasing frequency and severity of harmful algal blooms (HABs) in Lake Erie have been troubling developments in the past few decades. Excess loads of phosphorus (P) from the watershed are considered to be a primary ... -
Neutron interferometer crystallographic imperfections and gravitationally induced quantum interference measurements
(American Physical Society, 2017-01-25)Dynamical diffraction leads to an interesting, unavoidable set of interference effects for neutron interferometers. This experiment studies the interference signal from two and three successive Bragg diffractions in the ... -
Perturbations to nutrient and carbon cycles by river damming
(University of Waterloo, 2017-06-30)The damming of rivers represents one of the most far-reaching human modifications to the flows of water and associated matter from land to sea. Globally there are over 70 000 large dams whose reservoirs store more than ... -
Ultra Low Dissipation Silicon Nanowire Resonator Arrays for Scanning Probe Applications
(University of Waterloo, 2020-01-23)This work describes the fabrication and characterization of silicon nanowire oscillators for use in ultra-high sensitivity force detection. These structures are optimized for use as scanning probes by fabricating ...
