Development of an aligned rolling footgear to reduce seabed impacts of bottom trawl fisheries

Northern Shrimp (Pandalus borealis) and Greenland Halibut (Reinhardtius hippoglossoides) located off the east coast of Nunavut (Arctic Canada) are currently harvested by factory freezer vessels using bottom trawls. This fishery is a major contribution to the territory’s economy. However, bottom trawling is not without its ecological impact. Bottom trawl’s footgear, located below the fishing line and in contact with the seabed to protect the netting and to guide animals into the trawl net, can cause an impact to the seabed.

Plasmonic Nanoparticle Enhanced Seawater Desalination

To combat the growing need for accessible freshwater sources across the globe, new technologies that don’t rely on fossil fuels are ideal. Additionally, these technologies should be easily implemented in the developing communities that need them most for lower cost than the current options. The purification of seawater, also known as desalination is a highly attractive method due to the large amount of easily accessible saltwater, though current methods are highly fossil-fuel dependent.

A real-time wideband underwater localization system using passive acoustic monitoring

This project provides a software solution for detecting, classifying, and tracking moving sound sources underwater from the generated sounds. Generally, monitoring shipping traffic largely rely on the automatic identification systems (AIS) installed on the vessels. The ability to track these vessels is at the mercy of the functionality of the transponders onboard the vessels and the reliability of the communication link to the base stations. Similarly, to detect and track marine mammals, underwater tags are often embedded on them to provide information about their specific locations.

Porous materials as a filtration method for ship exhaust

The Canadian government has vowed to reduce their pollutant emissions by 2030 in order to curb the effects of climate change. This means that shipping companies must make strides to reduce their overall emissions. This project will use novel sponge-like frameworks, called metal-organic frameworks (MOFs), to remove environmentally toxic pollutants from exhaust gas. The materials currently being utilized for pollutant gas removal (e.g.. limestone) are often are very minimally active by weight, this is not the case for MOFs.
