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
RBRlegato C.T.D & RTSYS NemoSens
RTSYS has integrated the RBRlegato3 C.T.D on the NemoSens© micro-AUV for low-power measurements of temperature, pressure, salinity, and sound velocity. The NemoSens is a 90cm long micro-AUV and an evolution of the RTSYS range of larger AUVs. It is lightweight, easy-to-use, modular, and intended for water quality, hydrographic, and acoustic surveys, building on RTSYS’s years of acoustics experience. NemoSens uses … Read More
RBR instruments study sea level rise in the Canadian Arctic
Since the writing of this story, published in ECO Magazine, the Milne Ice Shelf has collapsed into the Arctic Ocean. A team of Canadian and American researchers are using RBR temperature and salinity loggers to study how the Arctic’s ice shelves are changing over time. By understanding their disappearance, the researchers are able to predict the dynamics of the much … Read More
