I have a student working on a class project on CA's Central Valley. We are absolutely stumped trying to find any specific paleoclimate data (like 10000-100000 years) for the valley. The answer might be that it doesn't exist, but if anyone has any ideas, let me know. #paleoclimate

One of the challenges of making good #maps is choosing colours that work well for those with colour deficiency. To help I use a simulator on my phone.

I tried it out at the grocery store and was surprised by how everything looked yellow.

These photos are for severe red green blindness (#protanopia).

Really useful resource!

My mind is blown by this global geological map resource https://macrostrat.org/map/#x=16&y=23&z=2 Just zoom into somewhere you know and look at the detail…

I went hiking in the Ozarks on Saturday morning and stumbled on a small patch of frost flowers!

This is the first time I've seen them, and I was surprised to see them this late in the year. Frost flowers typically form during the first few hard freezes of fall when sap in certain small plants freezes, rupturing the stem and forcing water out. The water freezes on contact with the air and builds up into distinctive flower-shaped petals!

I am a Tlingit Indian artist and poet from Sitka, Alaska. Trying to get the hang of Mastodon. A sample of my artwork below.
This piece is “Behind the Mask: The Infinite Self” at Stonington Gallery in Seattle. Acrylic on birch, abalone and mother-of-pearl inlay, and gold leaf.

For people looking for #community on #Mastodon, one option is the page https://a.gup.pe. The attached image is the crux of how it works. Essentially tag or follow @ Whateveryouwanthere @ a.gup.pe (without the spaces, of course), it will create the group and boost anything it receives, so you get the activity of the community. #Bookstodon already has one (@ bookstodon @ a.gup.pe). #indigenous #CormacMcCarthy are two I've seen some conversation about recently.

“For deep time is measured in units that humble the human instant: millennia, epochs and aeons, instead of minutes, months and years. Deep time is kept by rock, ice, stalactites, seabed sediments and the drift of tectonic plates. Seen in deep time, things come alive that seemed inert. New responsibilities declare themselves. Ice breathes. Rock has tides. Mountains rise and fall. We live on a restless Earth.”

― Robert Macfarlane, Underland: A Deep Time Journey

Unexpected focal mechanism for M7.0 earthquake near #Solomon Islands. I would have expected a shallow thrust #earthquake on the #subduction interface, but it appear to be a steep #normal #faulting event. As of yet, only possible #tsunami waves on the nearby Honiara sea level station are a few cms in amplitude.

The UN's Dag Hammarskjöld library is holding a virtual event on #OpenAccess for Climate Justice. I'm glad this conversation is continuing well beyond the initiatives from OA Week in October.

The event is next week (30 November) and it's free. If you're advocating #OpenScholarship #OpenScience and trying to make sure that everyone has access to critical knowledge, here is the link to register https://research.un.org/conferences/webinar3

LISTEN: In audio obtained by ProPublica, an anti-abortion lobbyist suggests to Tennessee lawmakers -- who passed the nation's most restrictive abortion ban -- that IVF and contraception could be further regulated in a few years’ time.

Boudinage are one of the most spectacular geologic structures and some of my favorite rocks.

#WaterscenesoftheCenozoicWednesday is here again, so here's #paleoart of Conflicto, an ancient, Antarctic relative of ducks and geese that lived pretty much immediately after the extinction of non-avian dinosaurs. We have really excellent fossils of this bird so, despite it not being especially closely related to any living species, we know it strongly resembled modern geese.

Friendly #Mastodon tip of the Day 2

Filters are your best friend. If you don’t want content about Elon Musk , go to Preference > Filters and make one for "Musk".

Or #Twitter. Or anything you don't want to see.

Those posts will be hidden, and filters can be time-limited. So if you just want to filter out football chat during the world cup, you can do that.

In this drawing I attempted to portray a trilobite from an angle less often seen. This is Lycophron titan Australia's largest trilobite, and maybe third in the world. From the Ordovician of Central Australia
