Half with the stations have been sampled in icefree regions (sea ice concentration , a MedChemExpress Apigenin threshold to decide sea ice extent utilised by NOAANSIDC) (Figure b). In Situ Net Main Productivity The stations (Table) were selected such that NPP measurements, using C or Clabeled compounds, were offered at four or far more various depths, the minimum sampling depth of NPP wasLEE ET AL.Journal of Geophysical ResearchOceans.JCbetween and m depth, and extra in situ information had been offered such as surface chlorophyll, sea surface temperature (SST) and mixed layer depth (MLD). Most in situ NPP working with a C label (N) have been measured following h in situ or simulated in situ incubations along with the rest of the C information (N) have been measured after much less than a h incubation or an unknown time period; most information were GFT505 site reported as each day values. In situ carbon uptake rates employing a C label (N) had been measured just after h ondeck incubations Lee and Whitledge, ; Lee et al ; a good agreement amongst estimates of C and C productivity has been reported Cota et al . If hourly in situ production rates were reported, they were converted to daily production prices by multiplying using a calculated day length Forsythe et al , primarily based around the date and latitude whenwhere every single sample was taken. Making use of the a number of segment trapezoidal rule, NPP was integrated in the surface (Z) to the euphotic depth (Zeu; surface PAR) that was currently determined in the course of the incubation in the majority of the information. If Zeu was not reported, then it was calculated from out there light penetration information. Prior to any integration, when the NPP value at Z was not measured, it was assumed to be precisely the same because the Figure .
