Carbon and Nitrogen flux and isotopic signatures from surface tethered sediment trap data collected on research cruises for the Northern Gulf of Alaska LTER site in 2019, 2021

This dataset contains C and N flux and C13 and N15 isotopic signatures from a surface tethered sediment trap collected in 2019 and 2021 as part of the Northern Gulf of Alaska Long Term Ecological Reserach (NGA LTER) site. This data is represented by a single csv file with sediment trap data from cruises aboard the RV Sikuliaq (cruises SKQ201915S and SKQ202106S). Data includes flag values IOCE primary flag structure: 1 = good, 2 = unknown, 3 = questionable/suspect, 4 = bad, 9 = no data. These data are part of the Northern Gulf of Alaska Long Term Ecological Research (NGA LTER) program. The LTER program is a National Science Foundation–funded network of 28 sites nationwide that focus on the influence of long-term and large-scale phenomenon on ecosystems. Additional funding for sampling is provided by the North Pacific Research Board (NPRB), the Alaska Ocean Observing System (AOOS), and the Exxon Valdez Oil Spill Trustee Council (EVOS) via the Gulf Watch Alaska program.
