Investigating the potential for sea spray aerosol to mitigate coral bleaching

Mass coral bleaching events over the past decade have heightened the need for research into techniques to enhance survival of the Great Barrier Reef.Applying sea spray aerosol directly over coral reefs during periods of increased bleaching stress could mitigate bleaching by both locally reducing sea surface temperatures and by reducing incoming incident solar radiation. These effects are referred to as solar radiation management and can be broken up into the direct scattering of incoming solar radiation and via the interaction …

Precursors of atmospheric aerosols in the Southern Ocean and Antarctica

Atmospheric aerosols are tiny liquid or solid particles suspended in air. They have a significant role in the radiative balance through their direct interaction with incoming solar radiation (scattering and absorption), and indirectly through their interactions with cloud (they act as seeds on which water can condense to form clouds).Indirect effect is a much more complex problem, and involves the role of aerosols in the cloud formation and the modification of their properties such as changes to cloud reflectivity, cloud …

Online aerosol chemical characterisation using Particle Into Liquid Sampler coupled to Electrospray Ionisation Orbitrap Mass Spectrometry

Atmospheric aerosols are important as they have impact on earth’s climate and human health.Organic components represent a significant fraction of atmospheric aerosols. They can be directly emitted in the atmosphere or formed in the atmosphere by oxidation of gaseous precursors.Real-time characterisation of organic aerosol is required to understand their sources, formation and ageing (change) in the atmosphere.There are several mass spectrometry techniques currently used for real-time characterisation of organic aerosols. However, the techniques use hard ionisation, resulting in molecular fragmentation, …

Laboratory simulation of Secondary Organic Aerosol (SOA) formation

This project aims to investigate the interaction of anthropogenic (human-made) emissions and biogenic emissions from plants and trees and subsequent secondary organic aerosol (SOA) production in urban environments. This is relevant as SOA is part of particulate matter (PM), which is associated with smog events in cities, affects the climate and has negative impacts on human health.SOA is formed in the atmosphere by complex reactions of volatile organic compounds (VOCs) of anthropogenic or biogenic origin with atmospheric oxidants (OH radicals, …
