Speed of sound in waterWhat is speed of sound in water and why do we measure it? Sound-speed in water is a quantification of how fast sounds travel in water. The speed of sound in water depends on temperature, salinity, and pressure, and is therefore not uniform throughout different water environments. In the oceans, the speed of sound varies between 1450m/s … Read More about All about speed of sound in water – what it is, how it’s measured, and why we care
A proven standard in CTD sensor technology: RBR’s inductive conductivity cell
There are many tools to measure the physical properties of the ocean, yet few are as universal as the CTD. RBR’s inductive conductivity cell has taken its place at the forefront of high-accuracy CTD sensor technology as a proven standard that is robust, reliable, and uses a fraction of the power required for pumped CTDs. Conductivity, temperature, and pressure (depth) … Read More about A proven standard in CTD sensor technology: RBR’s inductive conductivity cell
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 about Understanding the glacier-ocean connection in Jones Sound: A multidisciplinary approach
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 about Resolving spatial and temporal variations in estuarine gas flux
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 about Constraining the dynamics of the Gulf of Urabá estuary and inspiring the next generation of Colombian scientists
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 about Evaluating the safety and efficacy of ocean alkalinity enhancement
