Time-series records of particulate fluxes reveal temporal variations in hydrothermal activity in the Wocan hydrothermal field, Carlsberg Ridge-Dataset

Description

In this study, we report the first detailed mineralogical and geochemical study of settling particles collected using moored time-series sediment traps near the Wocan hydrothermal field on the Carlsberg Ridge. We aimed to characterize the mineral and chemical compositions of the hydrothermal plume particles, quantify the settling flux of the particles dispersed by the hydrothermal plume, and investigate the causes of the vertical and temporal variations in the flux of the hydrothermally derived matter. Our study provides valuable information for understanding plume particle formation, transport, and deposition processes. The dataset includes: Table 1: Qualitative XRD data for representative samples in traps T5 and T6 at mooring 28-ST02 in the Wocan-1 hydrothermal field; Table 2: Average elemental concentrations of time-series settling particles in traps T5 and T6 at mooring 28-ST02 in the Wocan-1 hydrothermal field; Table 3: Settling particle fluxes at the 28-ST02 mooring site in the Wocan-1 hydrothermal field; Supplementary table 1: Elemental concentrations of time-series settling particles in traps T5 and T6 at mooring 28-ST02 in the Wocan-1 hydrothermal field; Supplementary table 2: The current measured at 150 m above the bottom from June 2013 to March 2014 at mooring site 28-ST02; Supplementary table 3: Vertical profiles of the potential temperature and turbidity at (A) 28I-L10 and (B) 28I-L11 in the Wocan-1 hydrothermal field.
