Rocks breaking in tension, compression, and shear; an interesting teaching talk yesterday by Dr. Drew Lubiniecki. Below is a fascinating figure showing the loss of porosity in deformation bands (DB) in a sheared carbonate. The original porosity is shown in blue.

Just a gentle reminder that through geological time, shifts in #carbonate producers mean that the geometry of carbonate platforms (as well as #reef shape) changed.
Please try to keep that in mind when drawing your models. I'm trying to stay mad, but I'm actually just growing disappointed.

Somehow, with everything going on, I forgot to acknowledge that the term started (and now a few weeks in). As taxing as it is, it's nice to be back in the classroom. Being able to talk about the #marine #carbon system and #carbonate rocks to #students is a nice change of pace.

Thermal-induced #crystallographic transformation in shells of #mussels reveal that crystallographic features in the #carbonate are more resistant to #diagenetic alteration than stable #isotope ratios.

#WeekendReading: Cala et al. on the dissolution kinetics of #carbonate minerals in the oceanic water column. Showing that the dissolution rate is proportional to the saturation state, seems trivial, but it really isn't.
Something like this was much needed for a while now.

#ShowYourStripes get new meanings as now you can also generate #biodiversity stripes as well as (for use #carbonate people) #OceanAcidification and aragonite saturation for different #ocean basins https://oceanacidificationstripes.info/

#NewPaper out in the world!
What destroys a #carbonate (#mesophotic) platform? It turns out that erosion, destabilization, and lower slope dismantling all work independently of each other.

#WeekendReading: Catching up on Wei and Zhang's thoughts on shallow-water #carbonate early #diagenesis. I think I'd like to play again at some point with this idea of diagenesis based correlation.

Cold seeps are apparently rather prevalent on the US Atlantic margin. To me that supports that near-seafloor #authigenic #carbonate formation (which happens there) is likely much more prevalent than previously considered.

My #firstpost on #Mastodon:

I am an Earth/climate scientist at the University of Arizona in #Tucson (southwestern US) focusing on the areas of #climate change, #paleoclimates, and #paleoceanography, with an emphasis on #ENSO, #monsoons, & #variability.

Our group uses #inorganic #geochemistry incl. measurements of #stableisotopes & #tracemetals in #carbonate rocks & #fossils (e.g., #foraminifera, #mollusks, & #speleothems) alongside climate #observations as well as #simulations to advance understanding of how the Earth's #climate & #oceans have changed in the past and can change in the future.

Some of my hobbies include:

#music: I am a fan of #metal and heavy music of all sorts, but tend to migrate towards #black, #death, #doom, #drone, #sludge, & #thrash. I also have a soft spot for #carnatic/#hindustani #ragas, #darkambient, oldschool-ish #hiphop, #triphop, and various forms of #electronicmusic.

#birds & #birding #photography bring me joy. Right now, I feel v lucky to be briefly back in my hometown of #Bengaluru, southern India, after three long years being able to see #oldworld birds I grew up with.

#GTD, #mindfulness, #organization, and (vs?) #producivity are things that I enjoy thinking about. Of late, I've been using #Things3, #Streaks, #Hobonichi w a #Lamy Safari, #Obsidian, #Overleaf, & #Bookends to get things done.

Thanks for reading!
