We caught some calanus finmarchicus!!

🌊 Another beautiful day teaching kids about the ocean and how we measure it in Halifax NS, aboard the historic CSS Acadia at the Maritime Museum of the Atlantic. One of the oldest hydrographic research ships still afloat! #CSSAcadia

Good call! Googling on those lead me to this article (screenshot for context):

Hey #FossilSky (is that a thing?)! These fossils are all over the shore at my family farm in NB Canada, along the Wolastoq (Saint John) river. I’d love to know if there’s a way to date them and/or identify species. Can someone help?? 🧪

A strong wind, a hay field in NB, a recently-turned 7yo enjoying summer, and a kite made out of a garbage bag, duct tape, bailer twine, and an old sheet made for a perfect summer day.

🌊 Today was World Oceans Day, and I set up some gear and demos with colleagues from the NS Maritime Museum of the Atlantic. It was a great turnout, and a lot of fun! (photo not representative because all the times it was busy there was no way I could grab a photo).🌊

At 1:06 in the video, it looks like the trawler also scooped up some scientific instrumentation ...

Ok, here's the most recent version. I'm removing atmospheric pressure from NOAA, and then converting mBar to dBar (which is very close to water depth in meters). Do depths of 0.4 to 1m seem right? I don't know if there is a MLLW offset that I should be adding; is that the "- 2.00" (ft) below?

Yeah. I see that's what you're doing for the website widget, and will do that too. For now though, still possible to do a harmonic tidal analysis. Not quite long enough to fit everything important, but getting there!

A combination of googling the sofar API, trawling through your github repo, and some copilot code conversions, and I'm almost there!

Good on him for sticking with it in his old age!

So long, and thanks for all the fish!

Today an otter that I didn't know lived in the city wandered through our backyard running and sliding across the snow on his belly and I was briefly granted relief from ... all of this. Didn't manage to get a camera on him quick enough (they're fast!) but look at these perfect tracks. 🦦❄️

Trying to make a case for why my ocean glider monitoring is relevant for the establishment of a marine conservation area. Sometimes a map is all you need! 🌊

The world is weird and confrontational lately, but recently I made some delicious turkey stock and while it was cooling it formed beautiful Rayleigh-Benard cells in the fat layer at the top.🧪

I almost forgot about #CTDappreciationDay! There aren't many aspects of my job that don't rely on CTD data. Here are some photos of our trusted SBE CTD and rosette sampling the Canadian Northwest Passage, the cutest little CTD on a turbulence profiler (made by JFE), and a glider CTD made by RBR.

Oh dear.

Hi! I'm Clark, an observational physical oceanographer working at the Bedford Institute of Oceanography in Halifax, Canada. I monitor Arctic outflows, manage a fleet of ocean gliders, and contribute to the international Argo program (see @argocanada.bsky.social). Also interested in internal waves. 🌊
December 11, 2024 at 4:36 PM
Yeah, not much of a whoosh. Here's what it looks like right now (i.e. 3 hours later).

Cool! Better than the oceanographic slide rule I've been planning on making myself:

Not Alaska, but I did exactly this (brought my kids) a few years ago when a dead blue beached near Halifax.

I helped recover one of our DFO ocean gliders earlier this week (mostly I took pictures, lol). It was a rough day for a recovery, but at least this one wasn't attacked by a shark! 🌊
