These data include water temperature, salinity, dissolved inorganic carbon (DIC), total alkalinity (TA), dissolved oxygen, and nutrients (nitrate, nitrite, phosphate, silicate, and ammonium). The cruise was funded by the National Oceanic and Atmospheric Administration (NOAA) Arctic Research Program (ARP) and supported by numerous agencies and institutions including the National Science Foundation (NSF). The carbon data were collected at sea and run using equipment from the Ocean Acidification Research Center (OARC) at the University of Alaska Fairbanks (UAF). Jessica Cross was funded by NOAA's Arctic Research Program and Natalie Monacci was funded by the Cooperative Institute for Alaska Research and the Alaska Ocean Observing System. The CTD operations on the cruise were managed by personnel from the Woods Hole Oceanographic Research Institute (WHOI). Dissolved Oxygen and nutrient data were collected by by personnel from the University of Washington Joint Institute for the Study of the Atmosphere (JISAO). Calvin Mordy was funded by the Ecosystems and Fisheries-Oceanography Coordinated Investigations (EcoFOCI) Program and NOAA's ARP. Phyllis Stabeno is co-Principal Investigator of the EcoFOCI program.

| Temperature | |
|---|---|
| Abbreviation: | CTDTMP_ITS90_DEG_C |
| Unit: | DEG C (ITS-90) |
| Observation type: | Measured |
| Analyzing instrument: | Seabird CTD |
| Detailed sampling and analyzing information: | A profiling CTD 911 was used to collect the conductivity, temperature, and depth data at each station. Data are processed using Seabird CTD software and calibration file. Post-processing at WHOI includes filtering extreme outliers, extrapolation of values from the top value collected at ~3-5m to the surface. Each cast is visually reviewed for reasonableness and density inversions (greater than 0.02 sigma-t) caused by spurious measurements. This process is facilitated by comparison of the outputs of the 2 temperature and conductivity sensors. Profile data are bin-averaged to 1 meter. |
| Quality flag convention: | All data points are either accepted (retained) or rejected (deleted) during processing, so data are all defined as good. |

| Analyzing instrument: | Seabird 43 |
| Detailed sampling and analyzing information: | In situ data was collected from a profiling CTD 911 paied with a SBE 43 to collect dissolved oxygen data at each depth. Data were originally proceseed to filter out extreme outliers and reviewed for reasonableness, along with other profile data. Seawater samples were collected for winkler tittations to be analyzed on a Langdon Amperometric tritrator. Oxygen was recorded in ml/l, and was corrected and converted into units of umol/kg. Calibration/conversion equation for less than 500m was (ml/l + 0.2310)*44.661 / density |
