So proud of Michael!! 😎

This work was a collaboration with @alvitello.bsky.social at @unipd.bsky.social and A. Ielpi and @ubcokanagan.bsky.social

Our results suggest that on Mars, values of the aerodynamic roughness length may reach up to 1 cm—up to two orders of magnitude larger than typically assumed. #NASA Ames, @stanforddoerr.bsky.social, @marslogander.bsky.social

Best wishes to you and your family, Laurie!

Congrats @jtuttlekeane.bsky.social !!!!!

Final stop with postdoc Carlos Alvarez on the "Aerodynamic #roughness of rippled beds under active #saltation at low atmospheric #pressure" (EP54A-03, 146 B).

Fr 4:20-4:30 pm.

#Wind tunnel work reveals impact of #bedforms and #saltation on #Mars.

#AGU24

(10/10)

Back to #Mars with PhD student Claire Blaske asking "Were #boulder fields along Mars' putative #ocean paleoshoreline deposited by a #tsunami?" (EP51B-06, 146
B).

Fr 9:25-9:35 am.

Or perhaps #floods? #glaciers? #impacts?

Collaborator @alvitello.bsky.social from U. Padua next will show that " #Vegetation leaves measurable imprints on the #morphodynamics or #meandering #rivers"
(EP51F-1434).

Fr 8:30 am-12:20 pm.

All about how #plants affect #meander shape!

PhD student Timmy Lui will take us to #Mars for his " #Segmentation of #dune crestlines using #convolutional #neural #networks"
(EP51D-1378, hall B-C).

Fr 8:30 am-12:20 pm.

A challenging task with potential to reveal much about #Mars #climate!

#AGU24

Kicking off Fr, PhD student Vittorio Colicci will present his MS work at MIT, "Examining the influence of early #tree #root geometry on #soil cohesion and anchoring strength using 3D-printed reconstructions" (EP51F-1439, hall B-C)

Fr 8:30 am-12:20 pm

Alternatively, undergrad Brian Amaro will talk about his "Automatic characterization of the size distribution of small #rocks on the #Moon and implications for orbiter-based extrapolations" (P44C-06, Liberty M at Marriott).

Th 4:52-5:02 pm.

#AGU24

Then former postdoc @agunn.bsky.social (now faculty at Monash) and recipient of #AGU24 's Luna Leopold award will deliver the Sharp lecture (Ballroom B). #Dunes galore on the horizon!

Th 4-5:30 pm.

(4/10)

Next: #Precambrian #Earth with PhD student @mcolinmarvin.bsky.social, with "Zircon microtextures: A record of Earth's earliest surface environments" (EP43F-03, 146 C).

Th 2:30-2:40 pm.

Tiny scratches pack much info on first ~90% of Earth's history!
