Beschreibung:
This dataset contains pooled statistics of stable isotope and shell measurements of individual ostracode valve analyses (IOVA) alongside available in-situ measurements of pH, surface and bottom water temperature (BWT), total number of valves analyzed per site, IOVA-δ¹⁸O, IOVA-δ¹³C, shell mass, shell length/width, along with their average and standard deviations at 17 sites across Lake Turkana, eastern Africa. These modern sediments were collected using a modified Ekman dredge during May to November 1979. The stable isotopic measurements were conducted at the [Paleo² Laboratory at the University of Arizona|https://thirumalai.geo.arizona.edu/] on a Thermo Kiel IV Carbonate Device coupled to a 253 Plus IRMS; the length/width measurements were performed on a MeijiTechno HDZ7000TS Digital Zoom Microscope System, and mass of each valve was measured using a Sartorius Cubis II Ultra-Micro Balance. Details about the materials can be found in https://doi.org/10.1029/2022GC010790
