•We model sea
level change during Snowball deglaciation and its aftermath.
•Predicted sea
level changes are characterized by significant geographic variability.
•Rapid local
melting or post-glacial crustal deformation may drive regional regression.
•Cap dolostones
may reflect deposition beyond the deglaciation phase.
4. A Tibetan lake sediment record of Holocene Indian
summer monsoon variability

•Tibetan lake
sediments reveal Holocene Indian summer monsoon rainfall variability.
•Grain size and
hydrogen isotopes detail local and synoptic ISM rainfall.
•Maximum ISM
rainfall and lake levels occurred from 10.1 to 5.2 ka.
•The ISM weakened
after 5.2 ka.
•ISM trends track
Indo-Pacific SSTs, the ITCZ, and Tibetan temperatures.

5. Evaluation of foraminiferal trace element cleaning
protocols on the Mg/Ca of marine ostracod genus Krithe

•We apply
foraminiferal trace element cleaning procedures to Krithe valves
•Sonication is a
critical step for accurate Krithe Mg/Ca analysis
•Reductive
cleaning can improve Krithe Mg/Ca BWT precision by > 1 °C
