Short summary
Stable oxygen and carbon isotope analyses of fossil bivalves, gastropods and fish ear bones (otoliths) is frequently used for seasonality reconstructions of past climates. We measured stable isotope compositions in multiple specimens of two bivalve species, a gastropod species, and two species of otoliths, from two early Eocene (49.2 million year old) shell layers. Our study demonstrates considerable variability between different taxa, which has implications for seasonality reconstructions.

Mollusk shells are valuable recorders of climate and environmental changes of the past down to a daily resolution. To explore this potential, we measured changes in the composition of shells of two types of bivalves recorded at the hourly scale: the king scallop Pecten maximus and giant clams (Tridacna) that engaged in photosymbiosis. We find that photosymbiosis produces more day–night fluctuation in shell chemistry but that most of the variation is not periodic, perhaps recording weather.

Fossil bivalves are an excellent climate archive due to their rapidly forming growth increments and long lifespan. Here, we show that the extinct bivalve species Angulus benedeni benedeni can be used to reconstruct past temperatures using oxygen and clumped isotopes. This species has the potential to provide seasonally resolved temperature data for the Pliocene to Oligocene sediments of the North Sea basin. In turn, these past climates can improve our understanding of future climate change.

ShellChron is a tool for determining the relative age of samples in carbonate (climate) archives based on the seasonal variability in temperature and salinity or precipitation recorded in stable oxygen isotope measurements. The model allows dating of fossil archives within a year, which is important for climate reconstructions on the sub-seasonal to decadal scale. In this paper, I introduce ShellChron and test it on a range of real and virtual datasets to demonstrate its use.

Climate researchers often need to compromise in their sampling between increasing the number of measurements to obtain higher time resolution and combining measurements to improve the reliability of climate reconstructions. In this study, we test several methods for achieving the optimal balance between these competing interests by simulating seasonality reconstructions using stable and clumped isotopes. Our results inform sampling strategies for climate reconstructions in general.

In this study, we present a detailed investigation of the chemical composition of 12 specimens of very well preserved, 78-million-year-old oyster shells from southern Sweden. The chemical data show how the oysters grew, the environment in which they lived and how old they became and also provide valuable information about which chemical measurements we can use to learn more about ancient climate and environment from such shells. In turn, this can help improve climate reconstructions and models.

We measured the chemical composition (trace-element concentrations and stable-isotope ratios) of a Belgian speleothem that deposited annual layers. Our sub-annual resolution dataset allows us to investigate how the chemistry of this speleothem recorded changes in the environment and climate in northwestern Europe. We then use this information to reconstruct climate change during the 16th and 17th century on the seasonal scale and demonstrate that environmental change drives speleothem chemistry.

Short summary
Middle–Late Devonian sedimentary rocks are often punctuated by anoxic black shales. Due to their semi-regular nature, anoxic events may be linked to periodic changes in the Earth’s climate caused by astronomical forcing. We use portable X-ray fluorescence elemental records, measured on marine sediments from Germany, to construct an astrochronological framework for the Kellwasser ocean anoxic Crisis. Results suggest that the Upper Kellwasser event was preceded by a specific orbital configuration.

The datasets presented are the density, water isotopes, ions, and conductivity measurements, as well as age models and surface mass balance (SMB) from the top 120 m of two ice cores drilled on adjacent ice rises in Dronning Maud Land, dating from the late 18th century. They offer many development possibilities for the interpretation of paleo-profiles and for addressing the mechanisms behind the spatial and temporal variability of SMB and proxies observed at the regional scale in East Antarctica.

At the end of the Cretaceous period, massive volcanism in India emitted enough carbon dioxide into the atmosphere to warm the climate globally above an already warm background state. We reconstruct late Cretaceous seawater temperatures much warmer than today using the chemistry of fossil oysters from the modern-day Netherlands and Belgium. Covariations in temperature and water chemistry indicate changing ocean circulation patterns, potentially related to fluctuating sea level in this region.

The Leeuwin Current transports warm water along the western coast of Australia: from the tropics to the Southern Hemisphere midlatitudes. Therewith, the current influences climate in two ways: first, as a moisture source for precipitation in southwestern Australia; second, as a vehicle for Equator-to-pole heat transport. In this study, we study sediment cores along the Leeuwin Current pathway to understand its ocean–climate interactions between 4 and 2 Ma.

We used new geochemical measurements to study the expression of astronomical climate cycles recorded in the Ordovician (~ 460 million years ago) geological sections of the Crozon Peninsula (France). This type of geological archive is not often studied in this way, but as they become more important going back in time, a better understanding of their potential astronomical cycles is crucial to advance our knowledge of deep-time climate dynamics and to construct high-resolution timescales.

A rare tropical record of the Paleocene–Eocene Thermal Maximum, a potential analog for future global warming, has been identified from post-impact strata in the Chicxulub crater. Multiproxy analysis has yielded evidence for increased humidity, increased pollen and fungi input, salinity stratification, bottom water anoxia, and sea surface temperatures up to 38 °C. Pollen and plant spore assemblages indicate a nearby diverse coastal shrubby tropical forest resilient to hyperthermal conditions.

Our micropaleontological analyses on three cores from New Jersey (USA) show that the late Maastrichtian warming event (66.4–66.1 Ma), characterized by a ~ 4.0 °C warming of sea waters on the New Jersey paleoshelf, resulted in a disruption of phytoplankton communities and a stressed benthic ecosystem. This increased ecosystem stress during the latest Maastrichtian potentially primed global ecosystems for the subsequent mass extinction following the Cretaceous–Paleogene boundary impact.

The Deep-Time Model Intercomparison Project (DeepMIP) is a model–data intercomparison of the early Eocene (around 55 million years ago), the last time that Earth's atmospheric CO2 concentrations exceeded 1000 ppm. Previously, we outlined the experimental design for climate model simulations. Here, we outline the methods used for compilation and analysis of climate proxy data. The resulting climate
atlaswill provide insights into the mechanisms that control past warm climate states.

The buildup and melting of ice during the early glaciations in the Northern Hemisphere, around 2.5 million years ago, were far shorter in duration than during the last million years. Based on molecular compounds and microfossils from sediments dating back to the early glaciations we show that the temperature on land and in the sea changed simultaneously and was a major factor in the ice buildup in the Northern Hemisphere. These data provide key insights into the dynamics of early glaciations.

The Cretaceous–Paleogene boundary, ~ 66 Ma, is characterized by a mass extinction. We studied groups of both surface-dwelling and bottom-dwelling organisms to unravel the oceanographic consequences of these extinctions. Our integrated records indicate that a reduction of the transport of organic matter to the sea floor resulted in enhanced recycling of nutrients in the upper water column and decreased food supply at the sea floor in the first tens of thousands of years after the extinctions.

The reconstruction of past snow accumulation rates is crucial in the context of recent climate change and sea level rise. We measured ~ 250 years of snow accumulation using a 120 m ice core drilled in coastal East Antarctica, where such long records are very scarce. This study is the first to show an increase in snow accumulation, beginning in the 20th and particularly marked in the last 50 years, thereby confirming model predictions of increased snowfall associated with climate change.

The relative contributions of astronomical forcing and tectonics to ocean anoxia in the Cretaceous are unclear. This study establishes the pacing of Late Cretaceous black cherts and shales. We present a 6-million-year astrochronology from the Furlo and Bottaccione sections in Italy that spans the Cenomanian–Turonian transition and OAE2. Together with a new radioisotopic age for the mid-Cenomanian event, we show that astronomical forcing determined the timing of these carbon cycle perturbations.

Classical spectral analysis often relies on methods based on (Fast) Fourier Transformation. This technique has no unique solution separating variations in amplitude and frequency. This drawback is circumvented by using a polynomial approach (ACE v.1 model) to estimate instantaneous amplitude and frequency in orbital components. The model is illustrated and validated using a synthetic insolation signal and tested on two case studies: a benthic δ18O record and a magnetic susceptibility record.

The use of stalagmites for last interglacial continental climate reconstructions in Europe has been successful in the past; however to expand the geographical coverage, additional data from Belgium is presented. It has been shown that stalagmite growth, morphology and stable isotope content reflect regional and local climate conditions, with Eemian optimum climate occurring between 125.3 and 117.3 ka. The start the Weichselian is expressed by a stop of growth caused by a drying climate.

The Levant is a key area to study palaeoclimatic responses over G-IG cycles. A precisely dated MIS 5 stalagmite (129–84ka) from Kanaan Cave, Lebanon, with growth rate and isotopic records variations indicate a warm humid phase at the last interglacial (~129-125ka). A shift in δ18O values (125-122ka) is driven by the source effect of the eastern Med. during sapropel 5 (S5). Low growth rates and high δ18O-δ13C values (~122-84ka) mark the onset of glacial inception and transition to drier phase.

Short summary
At the end of the Cretaceous period, massive volcanism in India emitted enough carbon dioxide into the atmosphere to warm the climate globally above an already warm background state. We reconstruct late Cretaceous seawater temperatures much warmer than today using the chemistry of fossil oysters from the modern-day Netherlands and Belgium. Covariations in temperature and water chemistry indicate changing ocean circulation patterns, potentially related to fluctuating sea level in this region.

In this study, we applied geochemical tools to well-preserved ∼180-million-year-old marine mollusc shells from polar and mid-latitude seas. These results indicate that polar shells grew at temperatures of 8–18°C, while mid-latitude shells grew at temperatures of 24–28°C. These results, together with previously published data, raise concerns about the ability of climate models to predict accurate polar temperatures under reasonably high atmospheric CO2 levels.

Approximately 600 million years ago, major environmental changes set the course for the emergence of animal life. Lithium (Li) isotopes in calcium carbonates can be used as a proxy to understand changes in the palaeo-environment. We conducted experiments that allow us to use Li isotopes in dolostones to extend our understanding of palaeo-environmental changes deeper into the geological record, where other calcium carbonates archives are not present.

Short summary
In this work, we apply a range of methods to measure the geochemical composition of the calcite from fossil shells of Pycnodonte vesicularis (so-called honeycomb oysters). The goal is to investigate how the composition of these shells reflect the environment in which the animals grew. Ultimately, we propose a methodology to check whether the shells of pycnodonte oysters are well-preserved and to reconstruct meaningful information about the seasonal changes in the past climate and environment.
In this work, we apply a range of methods to measure the geochemical composition of the calcite...
