In February 2021, two deep-sea moorings were deployed in the west Cretan Sea strait (south Aegean Sea) between Crete and Antikythira. The moorings were equipped with two RBRconcerto3 deep-sea loggers, including pressure, temperature, conductivity, and RBRcoda T.ODO dissolved oxygen sensors. The RBR loggers were deployed both at the strait bottom (~900 m) and at intermediate depth (300 m), paired with … Read More
RBRvirtuoso³ turbidity loggers deployed in coastal France as part of benthic ecosystem monitoring network
Off-shore of Brittany, in the western-most part of contiguous France, seven autonomous sea-bed platforms have been deployed to monitor turbidity. The measurements are being collected as part of France’s Réseau d’Observation Haute-Fréquence pour l’Environnement Côtier (ROEC), a local network (Brittany) for high-frequency coastal ocean observing, of which ROEC-Benth is the branch responsible for observing turbidity at the seabed. Bottom-mounted tripod … Read More
Observing ocean health: RBR, Dalhousie and DFO collaborate to develop new biogeochemical sensors
The ocean’s contribution to climate change may not be as visible as that of the atmosphere, but in lock-step with the atmosphere, the ocean is changing. The physical dynamics of its currents and temperature are changing, as well as its chemical and biological aspects; its biogeochemistry. Knowing the ocean’s biogeochemistry, including ecosystem health and the ocean’s ability to absorb carbon, … Read More
RBRvirtuoso³ D|tide16 tide gauges support iXblue’s 3D seafloor mapping and New Zealand’s national tide modeling
In 2019, iXblue’s New Zealand office first deployed RBRvirtuoso³ D|tide16 loggers to measure the tides, in support of their high-resolution 3D sonar-generated maps of the seafloor. High–accuracy, long-term and low-drift tide measurements are required in iXblue’s work, to remove tides from survey data, to link geodetic land and ocean data and to model the tides in coastal regions. iXblue specializes … Read More
RBRsolo³ D | Depth Loggers deployed in research on wave transmission through mangrove forests
In July of 2019, Tori Tomiczek and Anna Wargula, assistant professors at the United States Naval Academy’s Department of Naval Architecture and Ocean Engineering in Annapolis, Maryland, USA, mounted RBRsolo³ D depth loggers to the roots of mangroves in Key West, Florida, to determine the transmission of boat wakes through the saltwater-inundated trees. Their work will help to better quantify … Read More
How deep is the ocean? Mapping, measuring, and diving to the Mariana Trench’s Challenger Deep
There is only one submersible in the world that on any given day can dive, taking its pilot and one other person, to the deepest parts of the ocean. To reach the bottom of the Challenger Deep, Caladan Oceanic’s Deep Submergence Vehicle (DSV) Limiting Factor, descends through the water column for four hours. By the tenth minute of the 11 … Read More
