In 2021, RBR and Ocean Networks Canada (ONC) collaboratively designed and deployed a suite of instruments tailored to long-term and remote seismic research. This system is serviceable by remotely operated vehicle (ROV) while deployed, addresses instrument drift internally, can be deployed individually or integrated into a cabled array, and is entirely monitored by a portable data controller and power hub. … Read More
Understanding the glacier-ocean connection in Jones Sound: A multidisciplinary approach
Nestled between Ellesmere Island and Devon Island is Jones Sound, which is located in the rapidly and dramatically changing Canadian Arctic. The coastlines here are characterised by intricate fjords, many of which are highly influenced by tidewater glaciers (i.e. glaciers that end at the head of the fjord which discharge meltwater below the ocean surface). It is a region at … Read More
Resolving spatial and temporal variations in estuarine gas flux
Estuaries are thought to be major players in the global carbon budget, acting as significant sources of carbon dioxide to the atmosphere. However, the uncertainties on existing measurements are high. A recent study led by Dr. Malcolm Scully, a researcher at the Woods Hole Oceanographic Institution (WHOI), aims to improve our understanding of global fluxes of CO2 from estuaries by examining how … Read More
Constraining the dynamics of the Gulf of Urabá estuary and inspiring the next generation of Colombian scientists
Colombia’s Gulf of Urabá has historically been at the centre of many unanswered questions. The semi-enclosed tropical estuary is located in the southwestern Colombian Caribbean and is the largest estuarine system in the country. Despite its size, until recently it was one of the least studied ecosystems in Colombia. This changed in 2018, when scientists from the University of Antioquia, … Read More
Characterizing coastline changes and coastal hazards in the Canadian Arctic community of Grise Fiord.
Grise Fiord, located on Ellesmere Island in Nunavut, is the northernmost community in Canada’s Arctic and home to approximately 130 people. Over the last 20 years, community members have noticed significant changes to their coastline and increasing numbers of storm impacts. To better understand these changes and how they may need to adapt, they are collaborating with Dr. David Didier, … Read More
Evaluating the safety and efficacy of ocean alkalinity enhancement
Ocean Alkalinity Enhancement (OAE) may be a relatively safe way of storing CO2 in the ocean, potentially for thousands of years. This technique mimics natural weathering processes but accelerates them by adding low doses of alkalinity to the ocean’s surface, slightly increasing its pH and enhancing its ability to absorb CO2 from the atmosphere. Despite the enormous potential for OAE … Read More
