#Freshwater #lakes,like #Flughafensee #Berlin, play a complex #role in #globalwarming. Their #sediments are important #carbonsinks. However, they also release #CO2/#methane through microorganism activities. Furthermore, #lakeswarmup faster than surrounding air. L. Huang et al.(2024) address this and predict #shifts in #aquaticspecies #distributions and rearrangements of #freshwaterhabitats.

RE: https://mastodon.social/@arstechnica/116108759807158445
Which #geochronological #method helps to determine the #age of #sediments as precisely as possible in order to reconstruct biotic, ecological, and #climatic relationships over the course of geological eras? R. T. Tucker et al. (2025) were able to precisely date the #eggshells of non-avian #dinosaurs using a novel LA-ICP-MS U-Pb #calcitedating method. This enabled them, for the first time, to date the Upper Cretaceous strata of the #GobiBasin (Mongolia) radioisotopically.

A thought-provoking and wide-ranging talk yesterday by Andy Wickert, University of Minnesota.
His group has tracked changes in drainage patterns during the final deglaciation of Minnesota (~11 thousand years ago) to changes in erosion rates since the advent of mechanical agriculture.

Hwangto (Pedology 🟤)
Hwangto, a Korean loess soil, is a yellow-coloured soil, which contains high levels of potassium chloride and calcium. Hwangto is sometimes called a 'living soil' for its medical effects. Korean loess called “Hwangto”or “the red yellow soil or earth” has been a basic element or nourishment which has cultivated Korean nature and cultural heritages. Hwangto reve...

Desert pavement (Deserts 🏜️)
A desert pavement, also called reg, serir, gibber, or saï is a desert surface covered with closely packed, interlocking angular or rounded rock fragments of pebble and cobble size. They typically top alluvial fans. Desert varnish collects on the exposed surface rocks over time. Geologists debate the mechanics of pavement formation and their age.

Desert pavement (Deserts 🏜️)
A desert pavement, also called reg, serir, gibber, or saï is a desert surface covered with closely packed, interlocking angular or rounded rock fragments of pebble and cobble size. They typically top alluvial fans. Desert varnish collects on the exposed surface rocks over time. Geologists debate the mechanics of pavement formation and their age.
