Monitoring dissolved organic carbon in surface and drinking waters.
The presence of natural organic matter (NOM) strongly impacts drinking water treatment, water quality, and water behavior during distribution. Dissolved organic carbon (DOC) concentrations were determined daily over a 22 month period in river water before and after conventional drinking water treatment using an on-line total organic carbon (TOC) analyzer. Quantitative and qualitative variations...
متن کاملImproved automation of dissolved organic carbon sampling for organic-rich surface waters.
In-situ UV-Vis spectrophotometers offer the potential for improved estimates of dissolved organic carbon (DOC) fluxes for organic-rich systems such as peatlands because they are able to sample and log DOC proxies automatically through time at low cost. In turn, this could enable improved total carbon budget estimates for peatlands. The ability of such instruments to accurately measure DOC depen...
متن کاملDissolved organic nitrogen dynamics in coastal waters and the effect of copepods
15 15 The dynamics of freshly released and N labeled dissolved organic nitrogen (DO N) in the , 94 mm planktonic assemblages of coastal waters and the effects of herbivorous copepods on 15 1 those dynamics were assessed by applying NH under laboratory conditions. At the same time, 4 1 the rate of NH uptake and regeneration in the , 94 mm planktonic assemblages, and the rates of 4 1 15 ingestion...
متن کاملDissolved organic nitrogen uptake by seagrasses
We examined the ability of seagrasses to take up dissolved organic nitrogen (DON) with leaves (in situ) and roots (laboratory) in an oligotrophic tropical offshore meadow in Indonesia using 15N-labeled nitrogen (N) substrates. We compared the uptake of urea and amino acids with that of ammonium (NH z4 ) and nitrate (NO { 3 ) and determined uptake kinetics of amino acids for the seagrasses Thala...
متن کاملUsing fluorescent dissolved organic matter to trace and distinguish the origin of Arctic surface waters
Climate change affects the Arctic with regards to permafrost thaw, sea-ice melt, alterations to the freshwater budget and increased export of terrestrial material to the Arctic Ocean. The Fram and Davis Straits represent the major gateways connecting the Arctic and Atlantic. Oceanographic surveys were performed in the Fram and Davis Straits, and on the east Greenland Shelf (EGS), in late summer...
