Aside from the continuation of our dependence on fossil fuel, the “Macondo Deepwater Horizon” blowout was probably the worst fossil-fueled environmental disaster ever.

Another Angle on Standards
Standard metrics and vocabulary assures us that scientific and technical research is clearly understood, and repeatable. But it also can confer commercial advantages if the “Standard” conforms to already-developed, proprietary technologies.
Information only when needed
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.
Underwater Internet of Things starting to sneak up on us.
Under the auspices of the International Standards Organization (ISO), we’re working on the “Underwater Internet of Things” (UIoT). Our task is to make sure that it wreaks the least amount of havoc on marine life.
Now we’re getting somewhere! (v.2.0)
New pile-driving technologies promise to tame the unruly noise of installing shallow-water windfarms.
Now we’re getting somewhere!
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.
NOAA Fisheries 2024 “Acoustical Guidance” review.
Proposed “updates” of federal documents are required every five years to make sure the regulations reflect the ‘best available science.’ Predictably the 2024 “Updates” remain at least a decade behind the “best available science…”
Environmental energy flux density increasing exponentially
(Photo by David Kadlubowski) A number of our recent blogs have been orbiting around bird and whale energy perception, and how energy sources we impose on their habitats may compromise their environmental adaptations. This inquiry has ventured outside of what…
Negative impacts of negative pressure
Organisms are built to handle compression – positive pressure. But decompression. or “negative barotrauma,” is another matter.
How do migrating birds fly so far, so fast?
It is through their meteorological skills that blackpoll warblers can use 200mph (320kph) tailwinds to hurl their tiny little bodies 3.500 km (2,175 miles) over open ocean!
