We compared the responses of large benthic foraminifera to thermal stress in specimens from a population of Amphistegina lessonii, an abundant Indo-Pacific species, to specimens of A. gibbosa, its Atlantic counterpart, from a similar environment but two different water depths (5 m and 18 m). The test groups were exposed in a common experiment to three thermal-stress scenarios over a four-week period: (a) no thermal stress, i.e., control conditions at constant 25.5°C; (b) a single...
Late Cretaceous-Early Paleogene stable isotope and coarse fraction record of ODP Site 208-1262, supplement to: Barnet, James S K; Littler, Kate; Westerhold, Thomas; Kroon, Dick; Leng, Melanie J; Bailey, Ian; Röhl, Ursula; Zachos, James C (2019): A High‐Fidelity Benthic Stable Isotope Record of Late Cretaceous–Early Eocene Climate Change and Carbon‐Cycling. Paleoceanography and Paleoclimatology, 34(4), 672-691James S K Barnet, Kate Littler, Thomas Westerhold, Dick Kroon, Melanie J Leng, Ian Bailey, Ursula Röhl & James C Zachos
The Late Cretaceous-Early Paleogene is the most recent period of Earth history that experienced sustained global greenhouse warmth and was characterised by a dynamic carbon cycle. Yet, knowledge of ambient climate conditions and the evolution of atmospheric pCO2 at this time, along with their relation to forcing mechanisms, are still poorly constrained. Here we present an unprecedented 14.75 million year long high-resolution orbitally-tuned record of paired climate change and carbon-cycling (based on the oxygen and...
Seismic group velocities obtained at Campi Flegrei caldera by using ambient noise tomography with additional seismicity and geomorphology, supplement to: De Siena, Luca; Sammarco, Carmelo; Cornwell, David G; La Rocca, Mario; Bianco, Francesca; Zaccarelli, Lucia; Nakahara, Hisashi (2018): Ambient seismic noise image of the structurally controlled heat and fluid feeder pathway at Campi Flegrei caldera. 45(13), 6428-6436Luca De Siena, Carmelo Sammarco, David G Cornwell, Mario La Rocca, Francesca Bianco, Lucia Zaccarelli & Hisashi Nakahara
The files provide the measurement of seismic group-velocities obtained using ambient noise recorded at Campi Flegrei in 2011-13. Additional seismic locations and geomorphology are provided to reproduce the results of the study.

Paleomagnetic data points, magnetic susceptibility, colour reflectance and elemental data from a sediment outcrop of the Ashigong Formation near the Guide city in the northern Tibetan Plateau, China, supplement to: Wang, Zhixiang; Shen, Yongjin; Licht, Alexis; Huang, Chunju (2018): Cyclostratigraphy and magnetostratigraphy of the Middle Miocene Ashigong formation, Guide Basin, China, and its implications for the paleoclimatic evolution of NE Tibet. Paleoceanography and PaleoclimatologyZhixiang Wang, Yongjin Shen, Alexis Licht & Chunju Huang
Recent tectono-stratigraphy studies have shown that Northeast Tibet underwent significant tectonic uplift and basin partitioning at 13-8 Ma. This time window is also a period of significant changes in Asian monsoonal intensity, mechanisms of which remain poorly understood. Though many studies have tried to decipher paleoclimatic trends from sedimentary archives in NE Tibetan basins, it is often hard to distinguish local orographic effects from regional climate changes in such a tectonically active context. Here, we...
Cruise QC flag: E (see further details).
During cruise ARK-IX/4 sampling gears included the multibox-corer (MG) and the 0.25 m² giant box-corer (GKG). From one to fourteen subsamples of the size 0.023 m² (Sampling area) were taken from each MG and/or from one to four subsamples of the size 0.022 m² from each GKG using the rectangular frame.The uppermost 1 cm of sediment from each subsample was washed through the 0.2 mm sieve; the deeper 5 cm were washed through the 0.5...
Seawater carbonate chemistry and primary productivity, bacterial productivity, and the accumulation of chlorophyll a (Chl a) and particulate organic matter (POM) of coastal marine microbial community in Prydz BayStacy Deppeler, Katherina Petrou, Kai Georg Schulz, Karen Westwood, Imojen Pearce, John McKinlay & Andrew T Davidson
In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2016) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation by seacarb is 2018-05-23.
