Since the beginning of its large-scale production in the early twentieth century, plastic remains a critical material used throughout several industries. Despite serving many benefits, plastics are resistant to degradation ...
Nitrous oxide (N2O) is an increasingly abundant, atmospheric trace-gas that contributes
to climate change and stratospheric ozone depletion. Marine environments act as a net source of N2O to the atmosphere at global scales ...
The carbon isotope composition of ancient shallow water carbonates (δ13Ccarb) serves as the primary archive of ocean chemistry for a majority of Earth history and provides insight into the dynamics of global carbon cycling ...
Due to the expansion and retreat of the large ice sheets that covered most of Canada and parts of the northern United States during the Last Glacial Maximum (LGM), the surface of North America presently exhibits vertical ...
Different climate models predict different amounts of future warming over the 21st century. Such uncertainty of future warming projections can be narrowed down by emergent constraints identified based on the relationships ...
Nitrous oxide (N2O) is a potent greenhouse gas with a high global warming potential, but the underlying processes behind N2O production and consumption are not well understood. The ocean is known to be a strong source of ...
Cloud feedbacks are a large source of uncertainty in paleoclimate studies and in the constraint of climate sensitivity, and it is thought that climate sensitivity depends on climate state because of these feedbacks. Here ...
As a major sink for anthropogenic carbon, the oceans slow the increase of carbon dioxide in the atmosphere and regulate climate change. Future changes in the ocean carbon sink, and its uncertainty at a global and regional ...
Providing timely and accurate small-scale information about weather and climate
is challenging – especially for variables strongly controlled by processes that
are unresolved by low-resolution (LR) models. Motivated by ...
Do changes in how cross-equatorial energy transport is partitioned between the ocean and atmosphere impact the hemispheric climate response to forcing? To find out, we alter the cross-equatorial ocean heat transport in a ...
Average global ocean temperatures and the frequency and intensity of marine heat waves have been increasing over the last century. Temperature plays a critical role in defining the geographical range of the majority of ...
Rogue waves are unexpected, individual ocean surface waves that are disproportionately large compared to the background sea state. They present considerable risk to mariners and offshore structures when encountered in large ...
The marine biological carbon pump (BCP) leads to the transfer of carbon from the atmosphere to the ocean interior through the growth of photosynthetic plankton in the euphotic zone and subsequent sinking of particulate ...
The Coast Mountains in British Columbia contain over 10,000 km2 of glacial ice. While these glaciers have lost significant mass since the Little Ice Age (LIA; around 300 years before present), the melting rate has significantly ...
Multi-frequency backscatter acoustic profilers (echosounders) are used to measure biological and physical phenomena in the ocean in ways that are not possible with optical methods. Echosounders are commonly used on ocean ...
Numerical models of the atmosphere discretize space and time, and are unable to resolve processes smaller than model resolution. As such, the aggregate effects of these sub-grid scale processes must be parameterized when ...
This dissertation presents an analysis of the spatiotemporal variations of strong ground shaking and style of faulting at regional scales in the Chilean subduction zone. These properties are part of the two main components ...
Some fish produce sounds for a variety of reasons, such as to find mates, defend their territory, or maintain cohesion within their group. These sounds could be used to non-intrusively detect the presence of fish and ...
My PhD program is focused on how earthquake cycle deformation in subduction zones is governed by the rheology of the asthenosphere and lithosphere. The method of research is numerical modelling of deformation processes ...
Zooplankton play a key role in the functioning of marine ecosystems by transferring energy from phytoplankton to higher trophic levels. Additionally, because of their short generation times and ability to respond rapidly ...
