I'm on the blog team this year and we're really hoping for submissions featuring the huge range of polar research disciplines in the US. If you've got a story about recent adaptations, challenges, or improvements in your field, from new satellites to Arctic community initiatives, get in touch! ❄🥼🛠

YOU DUMB FUCKS. THIS IS ME.

I have a scooter. I can walk. I can't, however, walk through 80 miles of airport. I can walk onto an airplane or through hallways. I can't walk the .5 mile to the convention center.

People, get smarter, it's embarrassing at this point.

🚨 SAVE THE DATE 🚨

We're putting together a Planetary Science Community Meeting at the Kentucky Science Center in Louisville, KY on April 14–16 2026.

This is a grass-roots meeting for planetary scientists to gather, discuss, and organize to address pressing issues our community faces.

More than half of researchers now use AI for peer review — often against guidance A survey of 1,600 academics found that more than 50% have used artificial-intelligence tools while peer reviewing manuscripts.

Just decline the peer review invitation.

What are you people even doing?

#AGU25 🛠🪐

I'm standing next to a groundwater well on snow-covered ground in a cornfield that has been recently harvested. I'm wearing winter gear, holding a shovel, and smiling at the camera, blissfully unaware of the hardships in my near future (we spent half an hour trying to find the seventh instrument)

Photo angled downwards into a recently-dug foot-diameter hole in the ground, in which we have uncovered a very muddy seismometer. Also visible are my feet, the end of a shovel, a groundwater well, and some snow cover at the edges of the photo where we haven't disturbed it.

Last month we buried 7 seismometers in a cornfield to see if we could detect groundwater changes using ambient noise cross-correlation. Last week we went to retrieve them - my first snow day in Maryland, and much less corn than before! It sure added an extra layer of excitement to the process...

Great news for lunar science! 🧑‍🚀🌓🚀 NASA has selected the SPSS payload for the Artemis IV mission (2028) It will be deployed near the Moon’s South Pole to record moonquakes and reveal the deep interior. A proud international effort led by JPL! #ArtemisIV

Fascinating study from CU Boulder discussing dramatic effects associated with glaciers at grounding lines. Thinning of the glacier caused the seaward part to float, which let the ocean in to form cracks at its base and break off more icebergs.

I'm taking a selfie in front of my poster titled "Seismic Properties of Mélange in an Ice Shelf-Penetrating Rift from the ARROW Deployment at the Ross Ice Shelf". Some of the figures visible include a location map of the seismic array, a cartoon cross section through the rift, spectrograms, and work on ambient noise cross-correlation.

Having an excellent time at the @seismosocam.bsky.social Environmental Seismology conference so far, and thanks to everyone who came by our poster! (if you missed it, feel free to corner me later this week) Looking forward to the rest of the talks and posters lined up for the next two days 🥼❄🧪

PSA for folks visiting any National Public lands (parks, forests etc) during the shutdown: PLEASE take everything you brought in with you, including trash! Don't leave it in the bins if you can avoid it - those are emptied by National Parks/Forest workers. If they're furloughed that job isn't done.

Topographic Stress as a Mechanical Weathering Mechanism on Titan Stress perturbations induced by topographic features on Titan can lead to fracture in its icy crust, enhancing mechanical weathering This mechanism could help generate sediment on Titan Titan's ...

The last paper from my PhD is out today in JGR Planets! we looked at how Titan's topography can interact with tidal and possible tectonic stresses to generate fractures, which could erode over time to produce icy sediment and provide fresh surface area for hydrocarbon interxn

My POV as I'm walking up some stairs looking down at the brand new nameplate for my office door in my hand.

I am now a postdoc at @univofmaryland.bsky.social!

I'm joining the ARROW project to study some very cool seismic data collected at a floating rift in the Ross Ice Shelf, Antarctica. We hope to learn about the ice structure and seismicity of this region and how they're affected by tidal forces 🥼❄🧪

A jigsaw that will eventually be a photo of about 2/3 the surface of Enceladus, but currently only has the outer rectangular border and the curved outline of the moon completed. A box of puzzle pieces is sorted vaguely by lightness, while about 30 pieces with blue tint are laid out unassembled on the table.

Closeup inside the box of puzzle pieces. Many geological terranes are represented in the patterns of surface features on each piece, such as areas that look more like fresh snow compared to areas with deep, clear grooves.

Closeup of the blue-tinted pieces, which include many types of faulting and varied lightnesses.

Have we considered classifying geological terranes by making a surface image into a jigsaw and setting professional jigsaw solvers on it?

It’s not even funny how well these (independently evolved) piles are going to line up with descriptions of surface categories I learned during my PhD 😂

I’m working on a piece about funding basic science and if you’ve never explored spinoff.nasa.gov, I would really encourage you to do so. Even though I’ve been doing this for 20 years, it really is humbling and informative to see the ways in which space science works its way into our daily lives.

My dad and I, wrapped up in coats and hats, aim binoculars at a very clear night sky in the general direction of Jupiter, which is out of shot to the right. The constellation Orion is visible directly above our heads.

Took the parents to watch the planets align last night. We had moderate success (Mercury had already set by the time we got there) but the stars were very pretty ✨🔭🧪

A playful illustrated title reads “How different birds would act on a first date." A disclaimer underneath states: “Not approved by RSPB fact-checkers.” The image features a cute Coal Tit perched sweetly on a blue flower. The background is a romantic shade of pink.

How different birds would act on a first date...a thread.

Planetary Seismology on an Icy Moon

In the unlikely event that anyone has the time or energy to read my PhD thesis, it’s now publicly accessible!

I recommend Ch 2 if you want to watch me piece an icy moon together by trawling through a *whole bunch* of options for models and analogues ❄️🥼🪐🧪⚒️

The depths of the anti-trans hatred in sections of the British media is just shocking to behold. Trans people in the UK are a tiny group of people who must constantly suffer this blazing hot ire directed upon them by self-righteous bigots for no reason at all.

My fabulous supervisor @jessicairving.bsky.social has a #PhD project in this list looking at modelling quakes and working with seismic data on the rocky planets (v cool stuff). And if you want to pick someone's brain about doing a PhD at Bristol, feel free to reach out! ⚒️🧪🔭🪐

Set of 7 polyhedral dice, sharp-edged and transparent purple with lil moons inside, surrounding an absolutely enormous (~4-inch-tall) purple d20 with a handpainted Saturn inside

Set of 7 polyhedral dice, sharp-edged and transparent purple with lil moons inside, surrounding an absolutely enormous (~4-inch-tall) purple d20 with a handpainted Saturn inside - this picture from a lower angle than the first

My partner + flatmates got me these dope moon dice (byFlowerFox on Etsy) and *made* this giant Saturn d20 from scratch, like hand-painted and pressure-cooked resin and everything, all in secret?? The 7 lil guys are the moons you can see from Earth with a telescope?? I cannot comprehend

Thanks David for the fab summary thread and signal boost! 🪐❄️

Seismic Wavefield Modeling of Enceladus: Challenges and Opportunities Presented by a 3D Ice Shell We describe the effects of 3D ice shell thickness and 2D surface temperature on seismic phases transiting each layer of Enceladus Deviations from 1D ice structure can cause travel time difference...

3D Enceladus paper out now in JGR Planets (OA): doi.org/10.1029/2024...

Join us as we consider how Enceladus' 3D ice shell could affect body wave seismology! 🧪⚒️🪐🔭

This constitutes the last ~18 months of my PhD research with @jessicairving.bsky.social and I think our results are very cool indeed.

you’ll never guess what date I submitted my thesis

Overleaf down, nothing to do now but skeet about it I guess
