| CTD Temperature | |
|---|---|
| Abbreviation: | CTDTMP |
| Unit: | degrees celcius |
| Observation type: | CTD sensor |
| Sampling instrument: | CTD |
| Analyzing instrument: | 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 the Pacific Marine Environmental Laboratory 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. |

| Detailed sampling and analyzing information: | Samples were collected in 50 ml high-density polyethylene bottles that were rinsed first with 10% HCl prior to each station, and rinsed at least three times with sample before filling. Some samples were refrigerated for 3-12 hours prior to analysis. Nutrient samples were analyzed according to the methods of Gordon, et al (1993). Ammonium was measured using an indophenol blue method modified from Mantoura and Woodward (1983). |
| Replicate information: | In a direct comparison of EcoFOCI and BASIS methods, replicate frozen samples from the Bering Sea were analyzed with each method and found to be within 0.5 μM nitrate, 0.04 μM nitrite, and 0.7 μM ammonium (SD, n = 13). |
