Carbon system measurements, methane, nutrients, and sulfate concentrations from water column samples collected on R/V Rachel Carson cruise RC0107 in Clayoquot Sound, Vancouver Island, British Columbia during October 2023

These data include carbon system measurements, methane, nutrients, and sulfate concentrations from water column samples collected on the R/V Rachel Carson cruise RC0107 between October 2nd and 8th, 2023 in Clayoquot Sound, Vancouver Island, British Columbia. Water samples were collected at multiple sites in Clayoquot Sound.

CTD casts were conducted at numerous locations across the study area, and the corresponding CTD data are publicly available through the Rolling Deck to Repository (R2R). For sampling sites where water was collected, we provide data for the carbon system (DIC, pH, and alkalinity), methane, nutrients, and sulfate concentrations. These data will be valuable for those interested in carbon cycling and biogeochemistry in fjord systems. 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.
