The original and interpolated time series of dinoflagellate cysts export flux and multiple environmental factors off Cape Blanc, Northwest Africa
No full textDerived from multiple sources of high-resolution data that covered a time span from mid-2003 until early 2020, this dataset consists of dinoflagellate cysts (dinocysts) export flux time series obtained by a Honjo-type sediment trap offshore Cape Blanc and key environmental factors time series in the Canary Current upwelling ecosystem, Northwest Africa. The dinocyst time series comprises absolute abundances of all identified dinocyst taxa and four main groups showcasing particular ecological signals. Meanwhile, the time series of environmental factors originated from land observations (Nouadibhou Airport) of dust storm activity, surface wind speed, and surface wind direction, as well as satellite-based observations of aerosol dust frequency, sea surface temperature, and sea surface temperature anomaly. The resolution of each time series was standardised, and new time series were interpolated to meet the requirement of wavelet time series analysis, which could determine the common cyclical patterns in the time series of dinocysts and environmental factors. This approach aimed to distinguish climatic-driven changes by linking the interannual variations that occurred in environments and the dinocyst export flux cycles
Beryllium concentrations and ratios (10Be/9Be) of sediment cores PS67/197-1, PS75/054-1, and PS97/085-3
No full textWe obtained high resolution records of authigenic 10Be/9Be ratios in order to study the different impacts on 10Be deposition in marine sediments compared to ice cores. As changes in the atmospheric production of cosmogenic 10Be leave a global fingerprint in 10Be deposition fluxes this represents a powerful tool for the synchronization of climate archives. During the Laschamps geomagnetic field low (~ 41 ka BP) the global production rate of 10Be is expected to double. We therefore chose the depth intervals covering this period (PS67/197-1 8.51 – 16.31 m; PS75/054-1 1.80 – 8.30 m; PS97/085-3 3.80 – 7.60 m). For Be measurements 0.5 – 3.0 g of freeze dried samples of the cores were leached (Gutjahr et al., 2007), purified (Loftfield et al., 2024), and measured via ICP-OES (9Be) and AMS (10Be; Lachner et al., 2023 and Rugel et al., 2016). High resolution paleo- and mineralmagnetic measurements were performed on the 2.37 m – 15.36 m (~ 27 – 82 ka BP) interval of PS75/054-1 in order to improve the age model of that core. The magnetic susceptibility and paleomagnetic measurements of PS67/197-1 and PS97/085-3 have been described and published by Xiao et al. (2016) and Wu et al. (2021), respectively. For age model construction the time scales of EDC and EDML were updated to AICC2023
Effects of drought on generation 1 Lupinus bicolor (Fabaceae)
No full textData are for Lupinus bicolor grown in a dry-down drought experiment at UC Santa Barbara. Plants were grown in dry-down and well-watered conditions in order to study potential maternal effects. Data collected include seed production, vegetative and lifespan traits. The seeds were collected by hand between 2016-12-01 and 2017-02-28 near UC Santa Barbara Greenhouses. The greenhouse had climate controlled conditions with an average temperature of 21.1°C – 22.2°C. To estimate above ground volume, the plant height and the largest possible perpendicular cross-widths of the plant was measured and then multiplied the height x width x length
Vegetation cover during experimental drought and restoration in a coastal prairie in Santa Cruz, CA, USA in 2021
No full textThe average cover values of all plant species within experimental treatment plots of restored, unrestored, droughted and ambient rainfall plots from 2021. Data was taken using a modified Braun-Blanquet visual survey in six 0.25 m² quadrats to account for variation within a plot and eventually used to calculate the relative cover within a plot, therefore the total cover of each plot may exceed 100%
Thatch depth during experimental drought and restoration in a coastal prairie in Santa Cruz, CA, USA in 2021
No full textThatch depth, i.e. the height of litter from the soil surface was determined along with plant cover data in six subplots (0.25 m² quadrats) during a drought and restoration experiment in 2021
