Supplemental Data for Climate of the Past article \"Equatorial Pacific Carbonate cycles, 0-5 Ma: stratigraphy, dissolution, and paleoproductivity\", supplement to: Lyle, Mitchell W; Drury, Anna Joy; Tian, Jun; Wilkens, Roy H; Westerhold, Thomas (2019): Late Miocene to Holocene high-resolution eastern equatorial Pacific carbonate records: stratigraphy linked by dissolution and paleoproductivity. Climate of the Past, 15(5), 1715-1739

Mitchell W Lyle, Anna Joy Drury, Jun Tian, Roy H Wilkens & Thomas Westerhold
Coherent variation of CaCO3 burial is a feature of the Cenozoic eastern equatorial Pacific. Nevertheless, there has been a long-standing ambiguity whether changes in CaCO3 dissolution or changes in equatorial primary production might cause the variability. Since productivity and dissolution leave distinctive regional signals, a regional synthesis of data using updated age models and high-resolution stratigraphic correlation is an important constraint to distinguish between dissolution and production as factors that cause low CaCO3. Furthermore the...

High-resolution multiproxy analysis of a sediment core from high-elevation lake Bastani

Experiment on parasite infection

Kostas Sagonas, Britta S Meyer, Joshka Kaufmann, Tobias L Lenz, Robert Häsler & Christophe Eizaguirre
Laboratory-bred males of three-spined sticklebacks (Gasterosteus aculeatus) were assigned to one of two treatments: exposure to the nematode parasite Camallanus lacustris (exposed) or control (i.e. unexposed). After infection key fitness and immune traits were measured. Fish were then sacrificed and liver tissue was dissected. Reduced representation bisulfite sequencing was conducted on DNA extracted from whole liver tissue. Overall we aimed to investigated the role of host DNA methylation modifications to respond to parasite infections.

Daniel Gebregiorgis, Liviu Giosan, Ed C Hathorne, Pallavi Anand, Katrina Nilsson-Kerr, Anna Plaß, Andreas Lückge, Steven C Clemens & Martin Frank
X-ray fluorescence (XRF) core scanning of marine and lake sediments has been extensively used to study changes in past environmental and climatic processes over a range of timescales. The interpretation of XRF-derived element ratios in paleoclimatic and paleoceanographic studies primarily considers differences in the relative abundances of particular elements. Here we present new XRF core scanning data from two long sediment cores in the Andaman Sea in the northern Indian Ocean and show that sea...

Estuarine, Coastal and Shelf Science, 225, 106251

Francesca Bulian, Dirk Enters & Bernd Zolitschka
The coastal area of the southern North Sea passed through several stages of development during the Holocene starting with swamps and bogs on Pleistocene sands. These were covered due to the rising sea-level by brackish and intertidal sediments with intercalated peat layers indicating repeated shoreline replacements. We analysed a 4.6 m-long sediment core recovered south of the island of Norderney (East Frisia, Germany) using a multiproxy approach. The record comprises a vertical stack of changing...

High-resolution organic geochemical bulk parameter and biomarker records off eastern North Greenland

Nicole Syring
A high-resolution biomarker record was carried out on Polarstern Cruise PS93.1 (2015) to reconstruct past sea-ice variability off the continental eastern North Greenland shelf. This area is strongly influenced by cold surface waters and drift ice transported via East Greenland Current, meltwater pulses from the outlet glaciers of the Northeast Greenland Ice Stream and the build-up of landfast ice. The AMS 14C-dated Holocene Kastenlot Core PS93/025 reflects high sedimentation rates ranging between 25-30 cm/kyr over...
