I realized that if we were going to come up with clear regulatory guidelines (why we did this exercise), we would all need to be fishing in the same metrics pond.

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.
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…”
Field Report from OceaNoise2023
I’ve just returned from attending OceanNoise2023 – a tri-annual conference on marine bioacoustics – this one in Vilanova i la Geltrú, just 30 km down the coast from Barcelona, Spain. OceaNoise is one of the bi/triennial conferences that coagulate the…
Making the ocean even smarter II
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…).
Soundscapes and Systems
Listening to, and evaluating soundscapes, is a great way to understand the habitat from which it comes. A biologically healthy soundscape is like a well-tuned orchestra; acoustical niches are inhabited across the entire auditory band of its inhabitants.
Metric expressions
Manipulating time, space, sample count, and energy into visual fields, giving researchers methods to reach our collective imagination – toward a deeper understanding of the world we inhabit.
Cassandra’s conundrum and metrics
I often feel a bit like Cassandra, not being believed while trying to convey ideas before their time, and then having the satisfaction of finally seeing them implemented.
Exposure metrics in relief
…the beauty of this approach is that we don’t have to wait another ten years for the findings to become regulations, rather they provide some guidelines in applying existing regulations to inform current practice.
New Orleans ASA report
I have just returned from an Acoustical Society meeting held in New Orleans last week where I presented a paper on using natural occurring sounds and biological thresholds as a basis for an ocean noise criteria. Our proposed “metric” is simple to…
