1. File Name: 96LPRICH.OGa 2. Year 1996 3. PI L. R. Pomeroy 4. Others: none 5. Description: Whole-water enrichment experiment with near-surface Ogeechee River water, July 23, 1996 (survey cruise 3). 6. Keywords: enrichment, respiration 7. Research locations: Sta. 000 (at mouth),016 at 18 km from mouth and approximating 15 o/oo, and 050 at zero salinity. 8. Methods: Precision Winkler measurements of unfiltered river water before and after 13 h incubations at in-situ temperature in dark incubators aboard R/V Blue Fin. Five replicates each of zero time, 13 h control, added N, added P, added metals and vitamins (MV), added glucose (G), added N, P, MV, added N, P, MV, G, killed control. For details of concentrations and procedures see Pomeroy et al. 1995, Mar. Ecol. Prog. Ser. 117: 259. 9. Notes: See also 96LPRESP and 96LPDOXY for more data on respiratory rates and dissolved oxygen. 10.Variable Description precision/units coded TREAT Treatment See 8 See 8 KM km from mouth 0.5 km no DOXY Mean diss. oxygen 0.00 micromole no STDEV standard deviation 0.000 micromole no 1SE +/- 1 std error 0.00 no dO2 change in oxygen 0.00 micromole/hour no 11.
