Description: Whole-water enrichment experiment with near-surface St Marys River water, February, 1999. 6. Keywords: enrichment respiration lmer8 7. Research locations: Zero, 16, and 32 river km from mouth. 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 99LPRESP.SM(a and b) and 99LPDOXY.SM(a and b) for more data on respiratory rates and dissolved oxygen. Some samples are outside the inlet, E.
