Abstract

Recent proxy work, increasingly, have been painting the rise of oceanic oxygen level through time as a nuanced process. Approaches to capture and to interpret spatial heterogeneity in a systematic way may become necessary in the paleo-redox community. Paleoceanographers established sophisticated protocols for tackling similar challenges in relatively recent time scales (e.g. Cenozoic). In such a context, this talk will provide an overview of a carbonate proxy, namely iodine to calcium ratios (I/Ca). Different aspects of the proxy will be covered briefly, ranging from proxy validation in modern oceans to proxy applications across different time scales (Quaternary-Paleozoic) and to data-model comparison in selected studies.
