For determination of coccolith mass and length estimates of the sediment trap samples, the glass slide preparations of raw sediment trap material used for coccosphere identification were employed. A total of 2355 fields of view (FOV) were imaged using a Nikon Eclipse LV100 POL microscope equipped with circular polarisation and a Nikon DS-Fi1 8-bit colour digital camera. A detailed description of the circular polarization microscope set-up applied in this study can be found in40 (link) while further details of the methodology used here can be found in Supplement 4 .

Palynological analysis was carried out on the basis of procedures put forward by Moore et al. [34] , Lentfer et al. [35] and Horrocks [36] (link). 50 g dried powder samples were processed with HCl, KOH (10%, 100 ml), ZnCl2 (2.0 g/ml in density, 30 ml), acetic acid (100 ml), KI/IH (2.0 g/ml in density, 5 ml) and acetolysis mixture (1 ml concentrated H2SO4, 9 ml acetic anhydride). A tablet of Lycopodium marker (18583 grains) was added to each sample. The pollen samples were spread uniformly on glass slides and at least 500 pollen grains, excluding aquatic pollen and spores, identificated and counted using a Nikon Eclipse LV100POL microscope. Identification was aided by the use of reference materials collected by the Key Laboratory of Vertebrate Evolution and Human Origins of Chinese Academy of Sciences, Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences and published keys [37] .

NMR spectra were recorded on a Bruker Ascend 400 (400.13 MHz for 1H and 100.60 MHz for 13C) spectrometer. 1H chemical shifts were referenced to the proton resonance signal resulting from the protic residue in the deuterated solvent. 13C chemical shifts were referenced to the carbon resonance signal resulting from the deuterated solvent. Thermogravimetric analysis was carried out on a TGA Q5000 instrument (TA Instruments) under a nitrogen atmosphere. Elemental analysis was performed at the Organic Chemistry Research Center, Sogang University (Seoul, Korea) using an EA1112 instrument (CE Instruments, Italy). Powder XRD spectra were obtained with a Bruker D8 Focus diffractometer (40 kV, 30 mA, step size = 0.02°). Optical microscopic images were collected on a Nikon Eclipse LV100POL microscope equipped with a DS-Fi1 CCD camera.

Differential scanning calorimetry (DSC) was performed on a NETZSCH DSC 3500 Sirius calorimeter. The sample was enclosed into the aluminum pan, and then DSC scans were conducted under dry nitrogen gas. The heating and cooling rates were 10 °C min−1. Powder X-ray diffraction (PXRD) was measured on a Rigaku RINT 2500 diffractometer.
Optical microscopic data were captured on a Nikon ECLIPSE LV100POL microscope with a heat stage (Linkam, THMS600). UV (365 nm) and visible light (525 nm) irradiation was conducted with an ASAHI SPECTRA CL-1501 controller and LED lamp. UV-vis absorption spectra were recorded with a JASCO V-750 spectrophotometer, with sample concentration of 1.0 × 10−4 mol L−1 (CHCl3 solution).

Optical microscopy studies (University of Rochester) used a Nikon Eclipse LV100POL microscope with both transmitted and reflected light capabilities, a maximum 1,000× magnification, and a Spot Insight 4MP CCD color digital camera assembly. MOKE analyses were performed at the Naval Research Laboratories. Grains were mounted on epoxy stubs and polished (first with alumina to 0.5 m followed by 0.05 m colloidal silica) to expose the grain interiors. The instrument employed (Quantum Designs NanoMOKE3) is capable of detecting micrometer to submicrometer magnetic features at depths on the order of 1 to 10 μm beneath the polished surface. Samples were exposed to a magnetic field ( 500 mT) and imaged using both polar (field applied normal to grain surface) and longitudinal (field applied parallel to grain surface) modes. Reflected laser light and Kerr effect images were collected simultaneously, allowing for the discrimination between optical and magneto-optical features.

Bone fragments partially enclosed in the carbonate concretion were selected for petrographic microfacies analyses. Ten uncovered, polished petrographic thin sections (30 μm thick) were analysed via an optical light microscope in transmitted and reflected light, using a Nikon eclipse LV100POL microscope equipped with a Nikon DSFil digital camera with NIS-Elements BR imaging software. Selected portions of the thin sections were etched in an aqueous solution of 1% HCl between 10 and 30 s, air dried and C-coated for scanning electron microscope observations and element analysis (scanning electron microscopy-energy-dispersive X-ray spectroscopy). The analyses were carried out with a JEOL JSM-6610 LV scanning electron microscope equipped with a AzTEC EDS for element identification. The operating conditions of the scanning electron microscopes were 5–20 keV accelerating voltage for imaging, and 15–20 keV for elemental analyses.

Following Lentfer and Boyd [38] and Pearsall [39] , each 5 g dried powder sample was processed with NaHCO3 (5%, 30 ml), HCl (10%, 30 ml), H2O2 (30%, 30 ml) and KI/CdI2 (2.3 g/ml in density). In order to remove particles less than 20 µm, the sample was sedimented by Stokes’ Law. Based on a total of at least 500 phytoliths, identification and counting were carried out after the sample was dried at room temperature. Identification was made under a Nikon Eclipse LV100POL microscope using the standard keys [10] , [39] , [40] –[43] and the reference collection of the Key Laboratory of Vertebrate Evolution and Human Origins of Chinese Academy of Sciences, Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences. The phytoliths were designated in accordance with the International Code for Phytolith Nomenclature [44] (link).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
