I wish this amazing transect was a bit closer to us

I often look out on these forest-covered hills and mountains and wonder what it would look like if in an arid climate with little vegetation

yea, I don't mind doing these (as long as I don't feel rushed) ... it's also interesting the variability in what different institutions have candidates put together; e.g., I'm a fan of the 'self-assessment' statements, I like reading their own words about what they've done and where they are headed

time will tell, but I think for this specific application (coding), having this open discourse about AI is useful –– some of the students try things and then show me where AI did it wrong or gave them some very weird code; i.e., they are learning to be cautious and not trust it by default (2/2)

I've experienced this teaching my intro paleoclimate course (which is for any major/year for gen-ed credit) ... now, I do some *very simple* activities in the first couple weeks to provide some foundation ... by the end of the term they are pretty comfortable with it

is pyCoreRelator available to the community (e.g., on GitHub)? I could see it being useful for other applications

we need to move this AI hype along much faster ... hopefully the bubble bursts and a bunch of start-up bros lose a boatload of $$$ relatively soon ... I don't want this to drag on for years and years

if it's not happening already, there will be a 'aw shucks, just boys being boys, ha ha' defense of this and our national media outlets will happily lap that up

these guys aren't joking, these are exactly the type of people who will steer their movement towards increasingly heinous actions

when I teach my intro/non-majors climate course I bring up ERW to convince them that learning about the carbon cycle is relevant (and it works, these ideas pique their interest) –– but communicating the vastly different rates as Higgins does here must be incorporated (I'll use some of his stats)

yea, that all makes sense ... thanks for articulating that

when an ice stream advances out to cont. shelf edge, leading to isostatic subsidence (and RSL rise), does the ice front 'lift off' the grounding zone? or, are those processes at different timescales?
September 27, 2025 at 7:28 PM
I guess that is a key question ... is sed delivery to the slope primarily during glacial max (when grounding zone near/at shelf edge) or during early deglacial/retreat when meltwater is doing a lot of sed transport work ... and, as always, maybe both and it depends
September 27, 2025 at 6:04 PM
or, put another way, is the shelf-to-slope sediment delivery system is driven almost completely by sediment supply factors (which, in turn, have a bunch of drivers) and local SL stand is of little influence (?)
September 27, 2025 at 5:57 PM
we are mostly interested in the occurrence/timing of downslope (shelf edge to base-of-slope) sediment delivery as a function of the advance-retreat cycle –– e.g., although local SL is high during glacial max, the sed supply is sufficiently high to deliver sed to the lower slope
September 27, 2025 at 5:55 PM
maybe because the topography is high spatial resolution (but temporally static) whereas the atmospheric data is high resolution both spatially and temporally (?) ... most geologists (👋) likely don't know how to synthesize such info in a way that represents an overall (time-averaged?) behavior
September 27, 2025 at 4:56 PM
My question for any ice sheet researchers/experts reading this is if you can point me to some other studies that get into these complexities in more detail. There's plenty about modern glacio-isostasy and SL, but I'm interested in past glacial maxima (LGM or older) and shelf-slope sedimentation. 3/3
