The data focus on the Greenland Interstadial 1 (GI-1) interval (~14.7–12.9 ka), where finely laminated sediments allow high-resolution analysis. Measurements were performed using mass spectrometry imaging (MSI) on cryosectioned sediment slices with a spatial resolution of 200 µm. The dataset captures rapid SST variability associated with monsoon dynamics, including an abrupt warming of ~2°C during the transition from Heinrich Stadial 1 to GI-1. This dataset was generated to reconstruct high-frequency SST variability and assess the influence of South Asian monsoon systems on upper ocean conditions. Depth is presented as centimeters below seafloor (cmbsf) and age as before the year 2000 CE (b2k). 66.497333 66.497333 23.122333 23.122333 66.497333 23.122333 1998-04-21T00:00:00 1998-04-21T00:00:00 2.8963 3.5497 German Research Foundation DFG http://www.dfg.de/en/ https://doi.org/10.13039/501100001659 464898428 Micrometer-scale biomarker and elemental imaging on sediments from the northeastern Arabian Sea – reconstruction of the Indian monsoon evolution on a sub-decadal scale in the Holocene and the Bølling-Allerød interstadial https://gepris.dfg.de/gepris/projekt/464898428 SO130_289KL 23.122333 66.497333 -571.0 1998-04-21T00:00:00 0.0 SO130 SO130 MAKRAN 2 MAKRAN 2 Dubai, United Arab Emirates 1998-04-03T00:00:00 1998-04-03 Karachi, Pakistan 1998-05-03T00:00:00 1998-05-03 Sonne https://en.wikipedia.org/wiki/RV_Sonne DFCG 6909777 von Rad, Ulrich von Rad, Ulrich doi:10.2312/cr_so130 20060045 Sonne https://en.wikipedia.org/wiki/RV_Sonne DFCG 6909777 Kasten corer KAL 20.2 m 16088 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ DEPTH, sediment/rock Depth sed m depth http://purl.obolibrary.org/obo/PATO_0001595 sediment http://purl.obolibrary.org/obo/ENVO_00002007 rock Length L http://dbpedia.org/resource/Length Obreht Igor obrehtigor@gmail.com 0000-0001-9710-8365 Depth sed [m] Age Age ka b2k age http://purl.obolibrary.org/obo/PATO_0000011 Obreht Igor obrehtigor@gmail.com 0000-0001-9710-8365 Age [ka b2k] Alkenone, unsaturation index UK'37 UK'37 alkenone unsaturation index UK'37 UK'37 Mass spectrometry imaging (MSI) Obreht Igor obrehtigor@gmail.com 0000-0001-9710-8365 MSI-based UK'37 (MSI-based, Mass spectrometry ...)
