New progress in acoustic sensor deployment – contributions from GEORGE and TRICUSO projects
Acoustic sensors are valuable tools for observing wind and rain at sea, two key drivers of exchanges between the ocean and atmosphere. While passive acoustic methods have been used from moored and mobile platforms, their integration on autonomous profiling floats has been limited. Recent work by several partners within the GEORGE and TRICUSO projects has

New autonomous Total Alkalinity sensor improves ocean carbon measurements
New scientific article by GEORGE partner National Oceanography Centre (NOC) presents new developments in Total Alkalinity (TA) measurements. The authors have developed a submersible sensor for autonomous direct (in situ) measurements in full ocean depths. Direct measurements are critical for understanding the ocean’s role in the carbon cycle and for evaluating emerging marine carbon dioxide
