I have been digging out my old copies of John McPhee's #books, dipping in, remembering what it was like to be a new #geologist, and how it has carried across into #spatial #data, #geomorphology, #geomorphometry, #hydrology, #landcover, #engineeringgeology, #environmentalscience, #landuse, #massmovement and so much more......
This one paragraph reminded me so strongly of that time,, although I cannot of course write as eloquently:
--
"I used to sit in class and listen to the terms come floating down the room like paper airplanes. Geology was called a descriptive science, and with its pitted outwash plains and drowned rivers, its hanging tributaries and starved coastlines, it was nothing if not descriptive. It was a fountain of metaphor—of isostatic adjustments and degraded channels, of angular unconformities and shifting divides, of rootless mountains and bitter lakes..."

'Some (TopoBathy) Floodplain Images I Made A Few Years Ago, On The Mississippi R.
--
These are some (topobathy) floodplain images I made a few years ago for a specific usecase – and ‘stumbled’ across them again today, lookin’ for something else…
Every time I look at such things, the (engineering) geologist, geomorphologist, (pseudo) hydrologist, spatial data scientist in me is made happy in being reminded what access we have to (often open) spatial data and the sheer volume of it, and the use cases for which it can be leveraged.
We are lucky professionals…

Vortex Trapping Of Suspended Sand Grains Over Ripples

https://doi.org/10.1029/2023JF007620 <-- shared paper
--
“KEY POINTS
• Observations of vortex-trapped grains suggest delayed settling of advected grains, as well as delayed advection of grains mobilized from the bed
• Quantitative comparisons of vortex-trapped sand grains compared well with theoretical formulations by Nielsen (1992, https://doi.org/10.1142/1269) for a forced vortex
• Improved understanding of vortex trapping effects on sediment dynamics may decrease uncertainty in large-scale coastal model predictions..."

Sometimes when you are working, you realise what a truly long way we have come in terms of readily accessible spatial data…
I am looking at remote sensed data in Alaska, both the imagery and the elevation-derived hydrology, on a pseudo-randomly-selected sand bar that maybe no one has ever stood on, just to the east of Noatak National Park – and yet I can get an excellent sense of the hydrology, sedimentology, geomorphology, even the ecology…

“ • A survey of Lake Michigan located at least 40 large craters on the lakebed.
• Initial studies highlighted the spots as unknown shapes, but additional research revealed the craters are filled with marine life.
• Researchers expect to investigate further, seeing how these craters formed and if they’re really sinkholes…"
