“…The Speleothem Isotopes Synthesis and Analysis (SISAL) group was formed under the international Past Global Changes (PAGES) project and aimed at bringing together speleothem scientists, process modelers, statisticians, and climate modelers to develop a global synthesis of speleothem isotopes that can be used to further our understanding of past climate variability and in model evaluation. As part of this initiative, a template was created, outlining the necessary metadata for speleothem‐based records (Atsawawaranunt et al, ). This template (Comas‐Bru & Harrison, ) forms the backbone of properties applicable to speleothems‐based records presented here.…”

The progress of science is tied to the standardization of measurements, instruments, and data. This is especially true in the Big Data age, where analyzing large data volumes critically hinges on the data being standardized. Accordingly, the lack of community‐sanctioned data standards in paleoclimatology has largely precluded the benefits of Big Data advances in the field. Building upon recent efforts to standardize the format and terminology of paleoclimate data, this article describes the Paleoclimate Community reporTing Standard (PaCTS), a crowdsourced reporting standard for such data. PaCTS captures which information should be included when reporting paleoclimate data, with the goal of maximizing the reuse value of paleoclimate data sets, particularly for synthesis work and comparison to climate model simulations. Initiated by the LinkedEarth project, the process to elicit a reporting standard involved an international workshop in 2016, various forms of digital community engagement over the next few years, and grassroots working groups. Participants in this process identified important properties across paleoclimate archives, in addition to the reporting of uncertainties and chronologies; they also identified archive‐specific properties and distinguished reporting standards for new versus legacy data sets. This work shows that at least 135 respondents overwhelmingly support a drastic increase in the amount of metadata accompanying paleoclimate data sets. Since such goals are at odds with present practices, we discuss a transparent path toward implementing or revising these recommendations in the near future, using both bottom‐up and top‐down approaches.

“…These present-day observations are enormously useful to delineate and characterise processes influencing speleothem geochemistry, and of critical importance for the calibration of recent speleothem records against meteorological data.Speleothems can provide precisely dated, high-resolution palaeoclimate records, and thus they are powerful archives for examining changes in climate variability and modes, and refine the picture obtained by other palaeoclimate archives. Focusing on Western Europe, where a large amount of palaeoclimate records from both speleothems and other archives is available, provides an opportunity to disentangle changes in mean climate state and variability.Here, we provide an overview of climate in Western Europe, before describing the available data in SISAL_v1 [3]. This study is focused at highlighting the potential of this new database for reconstructing regional trends in δ 18 O spel , as well as identifying common issues encountered with speleothem records from this region, in particular with respect to mixed climatic controls (temperature, moisture source, precipitation amount) that often affect Western European δ 18 O spel .…”

The Potential of Speleothems from Western Europe as Recorders of Regional Climate: A Critical Assessment of the SISAL Database

Western Europe is the region with the highest density of published speleothem δ 18 O (δ 18 O spel ) records worldwide. Here, we review these records in light of the recent publication of the Speleothem Isotopes Synthesis and AnaLysis (SISAL) database. We investigate how representative the spatial and temporal distribution of the available records is for climate in Western Europe and review potential sites and strategies for future studies. We show that spatial trends in precipitation δ 18 O are mirrored in the speleothems, providing means to better constrain the factors influencing δ 18 O spel at a specific location. Coherent regional δ 18 O spel trends are found over stadial-interstadial transitions of the last glacial, especially in high altitude Alpine records, where this has been attributed to a strong temperature control of δ 18 O spel . During the Holocene, regional trends are less clearly expressed, due to lower signal-to-noise ratios in δ 18 O spel , but can potentially be extracted with the use of statistical methods. This first assessment highlights the potential of the European region for speleothem palaeoclimate reconstruction, while underpinning the importance of knowing local factors for a correct interpretation of δ 18 O spel . Quaternary 2018, 1, 30 2 of 30and AnaLysis (SISAL) database (SISAL_v1) contains 376 speleothem records from across the globe [3]. About a quarter of these records (92) are from Western Europe, making it the region with the highest density of published speleothem datasets worldwide [3]. This paper reviews these records within the wider (palaeo-)climatic context of Western Europe, with the objective to identify and promote the potential of cave sites in the region for future palaeoclimate studies. Moreover, we test the suitability of a large compilation of speleothem records to reveal the existence of regional trends in space and time [4].While early studies on Western European speleothems principally focused on their availability for temperature reconstruction using δ 18 O of the carbonate [5,6], it was quickly recognised that δ 18 O spel is driven by a complex interplay of regional and site-specific factors, such as moisture source and circulation dynamics, amount of precipitation, dripwater residence time in the overlying karst, cave temperature and ventilation dynamics, and potential kinetic effects during carbonate deposition [7,8]. Due to the filtering effect of the soil-karst system, the δ 18 O spel signal is usually strongly temporally attenuated compared to precipitation δ 18 O, and affected to varying degrees by local noise [4]. This is particularly pronounced at mid-latitude sites and over the Holocene, when ranges in δ 18 O spel are typically small (average standard deviation of Western European δ 18 O spel in SISAL_v1 is 0.36 ) and reflect only moderate climate shifts, as is apparent from other palaeoclimatic evidence (e.g., [9]). Over glacial-interglacial timescales, changes in the seasonality of precipitation and the spatial stationarity of climate patterns need...
