It is known that there was a lack of coral reefs in the Central Indo-Pacific during the Pliocene. The cause of this is unknown. This study uses a new SST record biased on biomarkers from the Coral Sea between 11–2 Ma to demonstrate a 2-degree cooling in the Central Indo-Pacific as part of the Late Miocene Cooling. When combined with other impacts associated with this event, this might explain the collapse of coral reefs. The new data shows the importance of SST changes in Coral Reef loss.

Salinity is an important and integrative measure of changes to the water cycle steered by changes to the balance between rainfall and evaporation and by vertical and horizontal movements of water parcels by ocean currents. However, salinity measurements in our oceans are extremely sparse. To fill this gap, we have developed a 334-year coral record of seawater oxygen isotopes that reflects salinity changes in the globally important Agulhas Current system and reveals its main oceanic drivers.

Accurately quantifying how the global hydrological cycle will change in the future remains challenging due to the limited availability of historical climate data from the tropics. Here we present the CoralHydro2k database – a new compilation of peer-reviewed coral-based climate records from the last 2000 years. This paper details the records included in the database and where the database can be accessed and demonstrates how the database can investigate past tropical climate variability.

In this study, we tested the ability of massive boulder-like corals to act as archives of land use in Malaysian Borneo to palliate the lack of accurate instrumental data on deforestation before the 1980s. We used mass spectrometry to measure trace element ratios in coral cores to use as a proxy for sediment in river discharge. Results showed an extremely similar increase between our proxy and the river discharge instrumental record, demonstrating the use of these corals as reliable archives.

We present a detailed petrographic, microanalytical and bulk-chemical investigation of 36 mafic rocks from drill hole GT3A from the dike–gabbro transition zone. These varitextured gabbros are regarded as the frozen fillings of axial melt lenses. The oxide gabbros could be regarded as frozen melts, whereas the majority of the rocks, comprising olivine-bearing gabbros and gabbros, show a distinct cumulate character. Also, we present a formation scenario for the varitextured gabbros.

To aid researchers working with living planktonic foraminifera, we provide a comprehensive review of names that we consider appropriate for extant species. We discuss the reasons for the decisions we made and provide a list of species and genus-level names as well as other names that have been used in the past but are considered inappropriate for living taxa, stating the reasons.

The study addresses the potential of marine shell-forming organisms as proxy carriers for heavy metal contamination in the environment. The aim is to investigate if the incorporation of heavy metals is a direct function of their concentration in seawater. Culturing experiments with a metal mixture were carried out over a wide concentration range. Our results show shell-forming organisms to be natural archives that enable the determination of metals in polluted and pristine environments.

The variability in the geochemistry among individual foraminifera is used to reconstruct seasonal to interannual climate variability. This method requires that each foraminifera shell accurately records environmental conditions, which we test here using a sediment trap time series. Even in the absence of environmental variability, planktonic foraminifera display variability in their stable isotope ratios that needs to be considered in the interpretation of individual foraminifera data.

The Labrador Sea is important for the modern global thermohaline circulation system through the formation of Labrador Sea Water. However, the role of the southward flowing Labrador Current in Labrador Sea convection is still debated. In order to better assess its role in deep-water formation and climate variability, we present high-resolution mid- to late Holocene records of sea surface and bottom water temperatures, freshening, and sea ice cover on the Labrador Shelf during the last 6000 years.

Tephra is fragmented material produced by explosive volcanic eruptions. Geochemically characterized tephra layers are excellent time marker horizons and samples of magma composition. TephraKam is database of the ages and chemical composition of volcanic glass in tephra from the Kamchatka volcanic arc (northwestern Pacific). TephraKam enables the identification of tephra sources, correlation and dating of natural archives, and reconstruction of spatiotemporal evolution of volcanism in Kamchatka.

Here, mid-ocean seasonality is resolved through time, using differences in the oxygen isotope composition between individual shells of the commonly used (sub)polar planktonic foraminifera species in ocean-climate reconstruction, N. pachyderma and G. bulloides. Single-specimen isotope measurements during the deglacial period revealed a surprising bimodality, the cause of which was investigated.

The oxygen isotopic ratio of water in fluid inclusions in speleothems is an important proxy for the changes in past hydroclimate and temperatures. This isotopic ratio, however, may be affected by isotopic exchange between the water and the host calcite. Here we evaluate this exchange reaction based on a laboratory experiment. We demonstrated that the exchange was detectable but not significant for temperature reconstruction, likely because the reaction occurred only with a thin calcite layer.

We analyzed sediment traps from the Cariaco Basin, the tropical Atlantic and the Mozambique Channel to evaluate seasonal imprints in the concentrations and fluxes of long-chain diols (LDIs), in addition to the long-chain diol index proxy (sea surface temperature proxy) and the diol index (upwelling indicator). Despite significant degradation, LDI-derived temperatures were very similar for the sediment traps and seafloor sediments, and corresponded to annual mean sea surface temperatures.

Here we report seasonally resolved sea surface temperature (SST) reconstructions for the southern Mozambique Channel in the SW Indian Ocean, a region located along the thermohaline ocean surface circulation route, based on multi-trace-element temperature proxy records preserved in two Porites sp. coral cores for the past 42 years. Particularly, we show the suitability of both separate and combined Sr / Ca and Li / Mg proxies for improved multielement SST reconstructions.

This paper shows the differences of nutrient release after dry and wet Saharan dust deposition in the tropical North Atlantic Ocean at 12° N. Incubation experiments were conducted along an east-west transect. Large differences were observed between both deposition types with wet deposition being the dominant source of phosphate, silicate, and iron. Both deposition types suggest that Saharan dust particles might be incorporated into marine snow aggregates and act as ballast mineral.

Our study provides insights into the factors governing the spatio-temporal variability of coccolithophores in the equatorial North Atlantic and illustrates how this supposedly oligotrophic and stable open-ocean region actually reveals significant ecological variability. We provide evidence for Saharan dust and the Amazon River acting as fertilizers for phytoplankton and highlight the the importance of the thermocline depth for coccolithophore productivity in the lower photic zone.

We collected Saharan dust at the Mauritanian coast as well as in the deep the North Atlantic Ocean, along a transect at 12 °N, using an array of moored sediment traps. We demonstrated that the lithogenic particles collected in the ocean are from the same source as dust collected on the African coast. With increasing distance from the source, lithogenic elements associated with clay minerals become more important relative to quartz which is settling out faster. Seasonality is prominent, but weak.

We reconstruct changes in the warm water transport from the subtropical to the subpolar North Atlantic over the last 10 000 years. We use stable isotope and Mg / Ca ratios measured on surface and subsurface dwelling foraminifera. Results indicate an overall stable warm water transport at surface. The northward transport at subsurface evolves stepwise and stabilizes at 7 ka BP on the modern mode. These ocean transport changes seem to be controlled by the meltwater inflow into the North Atlantic.

We studied seasonal and spatial variations in particle size of Saharan dust deposition along a transect in the Atlantic Ocean, using an array of moored submarine sediment traps. We show a downwind decrease in particle size, but seasonal changes are also prominent. In addition, the dust is much coarser than previously suggested and incorporated into climate models.

Our work provides a new coral proxy-based reconstruction of sea surface temperature (SST) from the coral reefs of Rodrigues Island, located in the poorly studied south-central Indian Ocean trade wind belt. This site is well located to study the SST history of the subtropical Indian Ocean and its teleconnections with the Pacific over long timescales. Our results provide insights into biases in coral Sr / Ca-based SST reconstructions and how to avoid them.

Recent Southern Hemisphere (SH) atmospheric circulation, predominantly driven by stratospheric ozone depletion over Antarctica, has caused changes in climate across the extratropics. We present evidence that the Brazilian coast may have been impacted from both wind and sea surface temperature changes derived from this process. Skeleton analysis of massive coral species living in shallow waters off Brazil are very sensitive to air–sea interactions and seem to record this process.

The upper part of stalagmite ky1 (from top to 42.769 mm depth), consisting of 678 laminae, was collected from a cave in northern China, located in the East Asia monsoon area. The time of deposition ranges from AD 1217±20 to 1894±20. The analysis shows that both the variations in the thickness of the laminae themselves and the fluctuating degree of variation in the thickness of the laminae of stalagmite ky1 have obviously staged characteristics and synchronized with climate.

Iron biogeochemical budgets during the natural ocean fertilisation experiment KEOPS-2 showed that complex circulation and transport pathways were responsible for differences in the mode and strength of iron supply, with vertical supply dominant on the plateau and lateral supply dominant in the plume. The exchange of iron between dissolved, biogenic and lithogenic pools was highly dynamic, resulting in a decoupling of iron supply and carbon export and controlling the efficiency of fertilisation.

In this paper we present, for the first time, results from single-chamber Mg/Ca analyses combined with single-shell δ18O and δ13C for four planktonic foraminiferal species from a sediment trap in the Mozambique Channel. Eddy-induced hydrographic variability is reflected in test carbonate chemistry of these different species. A species-specific depth-resolved mass balance model confirms distinctive migration and calcification patterns for each species as a function of hydrography.

1. We have reconstructed new meridional thermal and precipitation stacked records in the Indo-Pacific Warm Pool (IPWP) during the last termination.
2. Meridional thermal gradient variations in the IPWP show tight links to the Northern Hemisphere millennial timescales event.
3. Anomalous warming in the south IPWP region could induce the southward shifting of the Intertropical Convergence Zone (ITCZ) in the IPWP during the Heinrich 1 and Younger Dryas events.

We test two assumptions that are often made in paleoclimate studies by using observations and ask whether temperature and productivity proxy records in the Southern California Current can be used to reconstruct Ekman upwelling. By examining the covariation between alongshore wind stress, temperature, and productivity, we found that the dominant covarying pattern does not reflect Ekman upwelling. Other upwelling patterns found are timescale dependent. Multiple proxies can improve reconstruction.

The presented study focuses on the last millennium of the palaeoclimatic history of Svalbard region. The investigation was based on classical palaeoceanographic proxies, strengthened by the analysis of ancient foraminiferal DNA in down-core sediment samples. This study is the first attempt to implement the aDNA record in the palaeoenvironmental reconstruction. The aDNA data revealed even small environmetal changes that were not evidenced in the sedimentological and micropalaeontological record.

Coccolithophore distribution in 88 surface sediment samples in the Atlantic Ocean and western Mediterranean was mainly influenced by salinity at 10m depth. A quantitative coccolithophore-based transfer function was developed and applied to a fossil sediment core to estimate sea surface salinity (SSS). The quality of this function and the reliability of the SSS reconstruction were assessed by statistical analyses and discussed. Several centennial SSS changes are identified for the last 15.5 ka.

The key to gaining information on climate over the last millennia is the study of proxy records in ice and sediment cores, trees, etc. We measured the oxygen isotopic ratio in planktonic foraminifera of a high-resolution, well-dated central Mediterranean core.
The comparison between the variability detected in this core and that characterizing the Northern Hemisphere allows for local and global (hemispheric) climate variations to be distinguished.

Short summary
A coral reconstruction of past climate shows changes in the seasonal cycle of sea surface temperature in the south-eastern tropical Indian Ocean. An enhanced seasonal cycle suggests that the tropical rainfall belt shifted northwards between 1856–1918. We explain this with greater warming in the north-eastern Indian Ocean relative to the south-east, which strengthens surface winds and coastal upwelling in the eastern Indian Ocean, leading to greater cooling south of the Equator.
