RBR array collects fine-scale measurements in the strongly stratified centimeters-thick boundary layer under seasonal lake ice

Researchers from Germany, Russia and Finland deployed 12 RBRsolo³ T temperature loggers into an ice-covered lake in northern Finland to study heat transfer at the ice-water interface. The fine-scale measurements they collected are helping them to identify the role of turbulence in the boundary layer. The 2018 study, “Turbulent mixing and heat fluxes under lake ice: the role of seiche … Read More

Uncovering the Ocean Dynamics Off the Coast of Madeira Island, Portugal

In the lee of Madeira Island, a famous-to-oceanographers formation occurs. To better understand ‘Madeira-Mode Water’, a team of researchers from the Oceanic Observatory of Madeira (OOM) set out in July, 2018, with an RBRconcerto³ CTD mounted to a Del Mar Oceanographic (DMO) Wirewalker and observed the daily thermocline cycle at a new level of detail. From the Portuguese naval ship … Read More

Wave data and modeling inform harbour planning in southern Nova Scotia

The small fishing harbour of Lower Sandy Point, near the southern tip of Nova Scotia, was modified to reduce the agitating effects of swell. Breakwaters were added, nearly enclosing the harbour. The resulting structure – approximately in the shape of two backward Ls with an opening between their bases – successfully reduced the swell, and, several times each year, in … Read More

The Coordinated Canyon Experiment: studying Monterey Canyon’s turbidity currents

Turbidity currents deliver sediment from the continental slopes to the deep ocean and threaten infrastructure such as submarine fiber-optic cables. The Coordinated Canyon Experiment (CCE), led by MBARI and USGS, used RBR turbidity sensors to continuously monitor the seafloor along Monterey Canyon for 18 months. The RBR turbidity sensors allowed the researchers to calibrate ADCP backscatter data and measure with new detail the … Read More

From Antarctica to Jupiter’s Moons

Since 2014, a group of researchers from the Georgia Institute of Technology (GIT) have been working in Antarctica to develop the underwater vehicle called the Icefin. Funded by NASA through the RISE UP (Ross Ice Shelf and Europa Underwater Probe) grant, the Icefin has been developed to study the under ice conditions on Jupiter’s moon Europa. The GIT team are … Read More

CROW and Collecting Wintertime Data in the Arctic Ocean

“This year we were working at minus 35 and we realized, that’s where just about everything starts to work badly. We had snowmobile issues. We had ice auger issues. We had plastics breaking. I noticed for one of the few times that the local Inuit Rangers we were working with were cold. These are the guys who take their gloves … Read More
