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

The Whale Watchers

RBRconcerto CTD

Close to the small New Zealand town of Kaikoura, the Kaikoura Canyon creates a unique opportunity for researchers to study sperm whale populations due to its proximity to the New Zealand coast. Just over a kilometre away from a mountain range with peaks over 2200 metres, the Kaikoura Canyon plunges to 1000m depth, and it connects with the Hikurangi Trough which … Read More

It Walks the Line: a Wirewalker™ record deployment

In September of 2016, a surface wave-powered Wirewalker™ descended to the bottom of its 100-m wire, reversed direction, and smoothly ascended to the surface. Onboard, a payload of instruments took detailed measurements of physical and biological properties in Southern California’s La Jolla submarine canyon. It was the first cycle the Wirewalker would complete at the La Jolla canyon mooring – … Read More

Lake Tahoe’s Nearshore Network and Protecting Water Clarity

Renowned for its cobalt blue colour and clarity, at 1,900 m elevation, Lake Tahoe is North America’s largest alpine lake. It straddles the California-Nevada border and on all sides rise the peaked Sierra Nevada mountains. Over two million people visit the Tahoe region annually; Frank Sinatra once owned a casino on Lake Tahoe’s shore. It’s little surprise then, that when … Read More
