Data from: Evaluating tooth strontium and barium as indicators of weaning age in Pacific walruses

Casey Clark, Lara Horstmann & Nicole Misarti
A dataset of calcium-normalized 88Sr and 137Ba concentrations from laser ablation transects across the cementum layer of 107 (female: n = 84, male: n = 23) Pacific walrus (Odobenus rosmarus divergens) teeth. Dataset includes spreadsheets containing elapsed time of laser ablation transect in seconds (ElapsedTime_s; laser transect speed = 5μm/s), calcium-normalized strontium concentrations (Sr_ppm_m88; values below limit of detection replaced with 1/2*limit of detection, see methods), and calcium-normalized barium concentrations (Ba_ppm_m137; values below limit of...
