If this approach was employed in the Underwater Internet of Things – establishing communication channels predicated on unique frequency-shift sequences specific to the particular communication channels, it might go far in allaying our concerns about turning the entire ocean into a digital-communications mosh pit.
New pile-driving technologies promise to tame the unruly noise of installing shallow-water windfarms.
While the ocean is 10 times louder now than it was just 50 years ago, a new propeller design promises to roll the noise back. This will make a huge quality difference for the ocean’s inhabitants.
The expansion of a fossil-fueled global economy over the last century has driven an historically unprecedented growth in global prosperity, technological advancement, and improvement in life-quality for a plurality of our planet’s human inhabitants. Unfortunately this phenomenon has falsely correlated…
It is June 8 – World Ocean Day, we’ve circled the sun yet another time. and the Ocean remains…
Most underwater communication signals will likely be acoustic, and likely be in the 8kHz – 25kHz range; overlapping human auditory range, and smack-dab in the sweet spot of marine mammal hearing range (as well as some fishes, and likely some marine invertebrates…).
Migrating birds need to sense “infrasonic” energy as a synchronized group, but also collectively for navigation. Windfarms may interfere with this sense.
This is one of those “how do you put the toothpaste back into the tube?” situations – at a global scale…
I’ve returned from Homer, Alaska where I was last week for the second phase of our Cook Inlet Seismic Survey monitoring project – sampling zooplankton in front of, and in the wake of the survey vessel…
Through a set of circumstances too Byzantine to unravel here this week I’ve found myself in Batumi, the Republic of Georgia on the coast of the Black Sea delivering and address to the Georgian International Maritime Forum (GIMF) While…
