This dataset contains 33 new sites at the Chilean margin and in the Drake Passage to verify the functionality of common regional and global calibrations for alkenones and a...

Using high-resolution 3D X-ray microscopy, this study aims to quantify skeletal parameters (e.g. length, diameter, surface area and volume) and examine skeletal deformity of...

In a year-long study, Pacific oysters (Magallana gigas) were monitored at two depths (1.5m, 6.5m) in a Coliumo Bay affected by coastal upwelling. Surface waters exhibited...

Low seawater pH can be harmful to many calcifying marine organisms, but the calcifying macroalgae Padina spp. flourish at natural submarine carbon dioxide seeps where seawater...

Calcification and growth of crustose coralline algae (CCA) are affected by elevated seawater pCO2 and associated changes in carbonate chemistry. However, the effects of ocean...

The sustained absorption of anthropogenically released atmospheric CO2 by the oceans is modifying seawater carbonate chemistry, a process termed ocean acidification (OA). By the...

The combination of global and local stressors is leading to a decline in coral reef health globally. In the case of eutrophication, increased concentrations of dissolved...

Ocean acidification (OA) can have adverse effects on marine calcifiers. Yet, phototrophic marine calcifiers elevate their external oxygen and pH microenvironment in daylight,...

With respect to their sensitivity to ocean acidification, calcifiers such as the coccolithophore Emiliania huxleyi have received special attention, as the process of...

This collection contains a total of four datasets, one for alkenone-derived and GDGT-derived temperatures in the South Pacific, another with OH-GDGTs in the very southern part...

Two coral reef sediments have been subjected to OA scenarios in the laboratory. Sediments from Magnetic Island (year 2014, 3 pCO2 treatments) were investigated under diffusive...

To understand the environmental impacts of added alkaline minerals on plankton communities, we enclosed natural coastal plankton communities using 53L microcosms and exposed...

Here, we use a fully factorial laboratory experiment to disentangle how diel light–dark and tidal inundation and exposure interact with warming and elevated pCO2 to regulate...

This dataset contains planktonic foraminifera assemblage groups defined by cluster analysis, alongside sea surface temperature (SST) reconstructions generated with the Modern...

The Tara Pacifc expedition (2016–2018) provided an opportunity to investigate calcifcation patterns in extant corals throughout thePacifc Ocean. Cores from colonies of the...

Lithium has proven a powerful tracer of weathering processes and chemical seawater evolution. Skeletal components of marine calcifying organisms, and in particular brachiopods,...

As human activities intensify, the structures of ecosystems and their food webs often reorganize. Through the study of mesocosms harboring a diverse benthic coastal community,...

Multibeam data were collected during RV Sonne cruise SO246 (2016-02-01 – 2016-03-21). Multibeam sonar system was Kongsberg EM122. Data are unprocessed and may contain outliers...

Global warming and ocean acidification are forecast to exert significant impacts on marine ecosystems worldwide. However, most of these projections are based on ecological...

Ocean acidification (OA) is expected to reduce the net ecosystem calcification (NEC) rates and overall accretion of coral reef ecosystems. However, despite the fact that...
