| Summary: | This data were collected and processed through the Northwest Passage Project, a US National Science Foundation funded program to explore the changing Arctic through an innovative expedition that engaged diverse audiences through real time interactions from sea, a high definition 2-hour documentary, and related community events. The expedition was conducted onboard the Research Vessel Ice Breaker (RVIB) Oden, where undergraduate and graduate students participated in the expedition along with local indigenous representatives, scientists, historians, journalists, and a documentary film crew. We are submitting two seawater datasets: one with in-situ and ex-situ data, and one with the waters composition results. The "NPP.full.dataset.csv" provides information on the following parameters collected from the Canadian Arctic Archipelago water column: Temperature, Salinity, Turbidity, Oxygen isotopes, Nutrients, Particulate Organic Matter (POM) data (e.g., Particulate Organic Carbon (POC), Particulate Organic Nitrogen (PON)), Methane data (e.g., concentrations, isotope ratio C13-CH4, oxidation rates constants). The "NPP.OMP.dataset.csv" provides information on the water mass contribution across the Canadian Arctic Archipelago. Here, we show the raw and standardized parameters used into the Optimal MultiParameter analysis (OMP) (such as, Absolute Salinity, the Arctic Nitrate:Phosphate tracer, and d18O), and the source waters fractions (i.e., Atlantic Water, Pacific Water, Meteoric Water, Sea Ice Meltwater). We also show the residuals of the OMP analysis in fractions. Both the datasets provide unique information on physical and chemical characteristics of the Canadian Arctic Archipelago waters, which will serve as baseline for further investigations.
