Applications of Global Navigation Satellite System Reflectometry (GNSS-R) in sea ice science have been among the efforts and prospects of the GNSS-R community for a long time. This dataset provides the observations of the quad-polarization shipborne GNSS-R prototype (identified by FpolGNSSR) in the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. FpolGNSSR, with four polarization channels, explicitly inhibits direct signal contamination through high antenna gain (11.3 dB). The data are in NetCDF format, with in-file metadata and variable description.

The stable isotope records for mid- and late- Holocene are based on two stalagmites, VEAJ collected in Alfredo Jahn cave and VECA collected in Caripe Cave, respectively. Both caves are located in northern Venezuela, adjacent to Cariaco Basin. The ẟ18O record was interpreted as a proxy for the proximity of the Intertropical Convergence Zone (ITCZ) to our study sites, and the ẟ13C record as a proxy for vegetation changes, as discussed in the paper 'Atlantic ITCZ variability during the Holocene based on high-resolution speleothem isotope records from northern Venezuela' (Medina et al., 2023). The ẟ18O and ẟ13C analyses were performed at the Stable Isotope Laboratory at the Institute of Geoscience of the University of São Paulo (Brazil) using a Thermo-Finnigan Delta Plus Advantage mass spectrometer. ẟ-notation in per mil units (‰) was used to express the sample isotopic ratios deviation from the Vienna Pee Dee Belemnite (VPDB) standard. Approximately 200 μg of CaCO3-powder subsamples for ẟ18O and ẟ13C stable isotopic analyses were collected using a manually controlled Sherline 5400 milling at a resolution of 0.4 mm for VEAJ and 0.5 mm for VECA. The ẟ18O and ẟ13C isotopic profiles of VEAJ-base, VEAJ-top left and VEAJ-top right are based on 530, 310 and 250 samples, respectively. VECA isotopic profiles consist of 670 samples. Since VEAJ-top left overlaps with some sections of the -top right record, we merged them through normalization (i.e., by subtracting the mean and dividing by the standard deviation) of the data inside the overlapping period, averaging both series and then reconstructing the shorter time series with the mean and standard deviation of the longer one. The geochronology was established by means of the U/Th dating method, using a multicollector inductively-coupled plasma mass spectrometers (MC-ICP-MS-Thermo-Finnigan NEPTUNE) at the Institute of Global Environmental Change, Xi'an Jiaotong University (China). The sampling for the U/Th dating was performed by extracting ~0.100 g of powdered carbonate with a handheld drill of the least porous and colored, most traceable layers along or at the side of each speleothem growth axis. A total of 42 U/Th ages were used to construct the age model for VEAJ and 25 for VECA, yielding an mean temporal stable isotope sampling resolutions of 3 and 23 years for VEAJ-base & top-composite, respectively, and 1.5 years for VECA. Some age reversals along the stalagmites were flagged as outliers using Bayesian statistics, and consequently removed from the age models. For other age inversions, an iterative procedure was applied to increase the range of uncertainty in order to fulfill the monotonicity criterion (Scholz and Hoffmann, 2011). The two different distance columns correspond to the sampling depths for the two adjacent stalagmites: the top left (VEAJ-top left) and top right (VEAJ-top right), that grew on the top of the lower section (VEAJ-base).

The basic observed water characteristics (pH, temperature, salinity and total alkalinity (TA)) and calculated water carbonate chemistry in the hatchery located in Zhanjiang, China (21.07°N, 110.74°E). The two-year-old Portuguese oysters Magallana angulata (also known as Crassostrea angulata) were collected from Wuchuan, China (21.37°N, 110.74°E). To be specific, about 300 adult oysters were transferred into six black fibreglass tanks (500L each) randomly and each culture tank contained about 50 individuals. Six tanks were independent and completely randomized to be separated into two different pH levels: ambient pH 8.0~8.1 as control (named F0_8.1) and pH 7.4 as ocean acidification (OA) treatment (named F0_7.4) for about one month to produce next generation and test for transgenerational effect. Low pH was driven by bubbling of carbon dioxide (CO₂) enriched air mixed with ambient air into filter seawater in the treatment tanks. pH and temperature were monitored daily with pH meter (Mettler Toledo InLab®, Switzerland) calibrated with NBS standards. Salinity was monitored using a dual-scale refractometer (MingRui, China). The seawater was utterly changed every two days and 50 mL seawater was preserved with mercury dichloride (HgCl2) every week for total alkalinity (TA) measurement. The TA was measured using an alkalinity titrator (Mettler Toledo G20S Compact Titrator, Switzerland), and partial pressure of carbon dioxide (pCO₂), carbonate ion (CO₃²⁻), saturation states of calcite and aragonite were calculated by CO2SYS program with equilibrium constants K2 and KSO4 (Millero et al. 2006).
