South Atlantic Multi‐Site Calibration of Coral Oxygen Isotope Paleothermometer
Geochemistry, Geophysics, GeosystemsCoral‐based stable oxygen isotopes (δ18O) have been used as a proxy for sea surface temperature (SST) since the 1970s, and δ18O–SST calibration studies have been fundamental to assure robust and faithful SST reconstructions.

Replication and reinsertion of stalagmites sampled for paleoclimatic purposes
International Journal of Speleology, 2018 Sampling stalagmites for paleoclimatic study can enter into conflict with preserving the beauty and integrity of caves. To minimize this impact, a variety of sampling strategies have been used by researches aware of cave-conservation issues. Based on our

Technical note: The Linked Paleo Data framework – a common tongue for paleoclimatology [PDF]
, 2016 Paleoclimatology is a highly collaborative scientific endeavor, increasingly reliant on online databases for data sharing. Yet there is currently no universal way to describe, store and share paleoclimate data: in other words, no standard. Data standards

Global‐Krigger: A Global Kriging Interpolation Toolbox With Paleoclimatology Examples
, 2023 Many applications in Earth sciences require spatial prediction, that is, obtaining a continuous scalar field from a set of discrete scalar data points on the Earth's surface.

International Journal of Climatology, EarlyView.Evaluating historical precipitation trends is complicated by interactions between variability in atmospheric circulation and thermodynamic forcing. This study assesses 1901–2023 UK winter precipitation trends in UK Climate Projections 2018 (UKCP18) global climate models using dynamical adjustment to separate circulation‐driven and non‐dynamical ...

New Holocene pollen records from the Brazilian Caatinga
Anais da Academia Brasileira de CiênciasWe present two pollen diagrams from the semi-arid Caatinga of the Catimbau National Park, in Pernambuco and from a Mauritia palm forest in the Caatinga/Cerrado ecotone of southern Piauí, NE Brazil, spanning the last 10,000 cal.

Sources and fates of silicon in the ocean: the role of diatoms in the climate and glacial cycles
Scientia Marina, 2001 Diatoms with their fast growth rates and obligate requirement for Si have a unique relationship to the oceanic Si cycle with the potential for controlling the nutrient and CO2 environment of large important areas of the ocean.

International Journal of Climatology, EarlyView.The study provides insights for post‐processing climate model output in complex terrain, useful for climate change impact models. We compared different bias adjustment and downscaling techniques from quantile delta mapping to simple lapse rates. We developed a new spatial downscaling method based on principal components analysis, which showed superior ...
