Oceanographer, founder of Tini Scientific. She/her 🏳️🌈. My goal in life was to throw expensive s**t in the ocean.
Then I did it and became a world expert on ocean sensors.

At Safeway this week, rainbows are “seasonal” and “tie dye”. Is the “tie die” deadly typo a secret code I should be worried about?

Brainstorming with @yuengdl.bsky.social on what fun educational experiments we can use a smartwatch for.
Here is a quick snippet of water temperature and IMU data I took this morning!

Impressively mind-boggling: 1 cubic km scale of underwater neutrino telescopes. It's not even complete & already detected a neutrino!
Hilariously mind-boggling: the number of times someone hit copy-paste in powerpoint to make this artist's impression of KM3NeT.🌊

It ALWAYS feels good to be able to write "I am a world expert on ocean sensors".

One of my favorite CTDs, one of three custom SBE 49s that went to the bottom of the Marianas Trench.
Rated to 12K meters, with super thick titanium casings, it pushed the limits of sensor engineering & performance. I know because I got to hold them and check out the data! #CTDAppreciationDay

Even though they are amazing at unlocking the secrets of the deep ocean, CTDs are terrible babysitters.

Moored!

Flying!
And as the Principal Physical Oceanographer at Sea-Bird for 6 years, I've built them too!

The data shows the magnetic field magnitude is affected by the change in temperature. There is even that exponential ramp up at the start of each plunge that is heat moving between the watch and the water.
A little internet digging confirms this, but I always like to see the effect with real data.

I can’t let sensor responses I don’t fully understand go.
Today, doing some hot/cold plunge tests to figure out whether the magnetometer (compass) is sensitive to temperature
TLDR: it is!

Pro tip: use a recycled flower vase for desktop debugging Apple Watch Ultra submersion sensors.
Deep enough to trigger sampling, but narrow enough that Bluetooth/wifi isn’t completely attenuated and you get live data and debugging output on your computer.
