Constraining the dynamics of the Gulf of Urabá estuary and inspiring the next generation of Colombian scientists

underwater CTD with pH and chl a sensors

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.

RBRvirtuoso3 logger in artic

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

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

Bridging local knowledge and scientific monitoring in coastal Nunatsiavut communities

CTD profiling in Labrador

The Arctic, a region greatly affected by climate change, is experiencing some of the highest rates of warming compared to the rest of the globe. Although much research has focused on understanding the resulting changes in these high-latitude ocean regions, there is a noticeable gap in coastal zone monitoring. This coastal area is often the most utilized and important to … Read More

Pushing what’s possible: High resolution estuarine sampling using rapid vertical profiling

Rocky Geyer - Boat Returning

Dr. Rocky Geyer, Senior Scientist at Woods Hole Oceanographic Institution, specializes in estuarine and coastal transport processes, sediment transport, and numerical modeling of estuaries and river plumes. But in actuality, everything Geyer studies boils down to a deep love of nature and physics. “At its core, science is about answering questions and understanding. For me, understanding how water mixes or … Read More

The coastal ocean is a dynamic and productive environment, critical for the success of fisheries, tourism, and local economies. But these productive environments are also associated with a variety of complex oceanographic features. To better understand and protect these ecosystems, many physical oceanographers are diving deeper into the dynamics that drive mixing and water exchange. Complex coastal features like currents … Read More
