Porewater geochemistry data from sediment cores collected on R/V Rachel Carson cruise RC0107 in Clayoquot Sound, Vancouver Island, British Columbia during October 2023

This dataset includes porewater geochemistry data for samples collected on the R/V Rachel Carson cruise RC0107 between October 2nd and 8th, 2023 in Clayoquot Sound, Vancouver Island, British Columbia. Sediment cores were collected at three sites in Clayoquot Sound. Data reported here include: porewater chemistry (sulfate, sulfide, Fe(II), pH). These data will be useful for those interested in understanding organic matter preservation in fjords and other coastal environments. Samples were collected by Molly Crotteau, Morgan Raven, Aaron Martinez, Natalya Evans, Marianna Karagiannis, Jordan Fishburn, and Jaqui Neibauer. Data were interpreted by Morgan Raven and Molly Crotteau.
