The visualization tool for wave heights is just in time for my classes on waves starting in November!
odl.bzh/CACKkfxO. thanks to @oceandatalab.bsky.social

fingers of higer waves are caused by refraction of swell over currents.The first time we saw this kind of feature was on Envisat ASAR.
7-day composite of wave heights from Scotland to France (dark red is 8 m) from SWOT KaRIN instrument (22 to 28 August 2025), showing land shadows and effects of currents on wave heights. In particular "fingers" of higher waves are pointing in the wave propagation direction and are caused by a focusing of waves in currents located "upwave" of the measurement.

This is an extremely common food-GHG pattern for food providers in North America and Europe, but it never fails to surprise people the first time they run the numbers and see it!

Just one food, beef, can account for 40-50% or more of the GHG emissions related to an organization’s food purchases.
erthsarah.bsky.social
Dr. Sarah Fortner @erthsarah.bsky.social · 9d
A reality check for me was working with students on an internal carbon accounting platform that Bon App our food provider uses. Beef was less than 5% of our purchases but around 50% of our food emissions even with international work to be plant forward.

Curse of private equity.

After US hospitals were acquired by private equity firms, patient death rates in the emergency depts rose by 13% compared with similar hospitals.

PE cut staffing, wages, investment; hiked profits.

People killed for profit.

Yet UK handing healthcare to PE.
Death rates rose in hospital ERs after private equity firms took over, study finds
The increased deaths in emergency departments at private equity-owned hospitals are most likely the result of reduced staffing levels, researchers say.

Waves and their organization from large scales to breaking events that generate foam and smaller ripples on top of all of these are fantastic to watch. This picture by Benoit Stichelbaut, taken in the Southern ocean, has a lot to teach us about how waves are organized. doi.org/10.1073/pnas...
Cover image: Pictured are high seas (10–12 meters) in the Southern Ocean. Fabrice Ardhuin et al. determined the heights and periods of ocean swells using satellite sea level measurements. The data revealed how large waves evolve in storms; energy from steep, short waves feeds long, high waves that radiate outward as swells from the storm. The highest waves observed were around 19.7 meters high with a period of around 20.2 seconds. According to the authors, uncovering the formation and distribution of large ocean swells can help design durable coastal structures. See the article by Ardhuin et al. e2513381122.
