Spatial variation of sediment mineralization supports differential CO2 emissions from a tropical hydroelectric reservoir
Substantial amounts of organic matter (OM) from terrestrial ecosystems are buried as sediments in inland waters. It is still unclear to what extent this OM constitutes a sink of carbon, and how much of it is returned to the atmosphere upon mineralization to carbon dioxide (CO2). The construction of reservoirs affects the carbon cycle by increasing OM sedimentation at the regional scale. In this...
متن کاملDistribution of Major and Trace Elements in a Tropical Hydroelectric Reservoir in Sarawak, Malaysia
This paper reports the metals content in water, sediment, macroalgae, aquatic plant, and fish of Batang Ai Hydroelectric Reservoir in Sarawak, Malaysia. The samples were acid digested and subjected to atomic absorption spectrometry analysis for Na, K, Mn, Cr, Ni, Zn, Mg, Fe, Sn, Al, Ca, As, Se, and Hg. The total Hg content was analysed on the mercury analyser. Results showed that metals in wate...
متن کاملPhytoplankton assemblages in lateral lagoons of a large tropical reservoir.
This study aimed to analyse the composition and ecological attributes of the phytoplankton assemblages in four lateral lagoons and in the main channel of Rosana Reservoir (Paranapanema River, SE Brazil). Fieldwork was carried out in September and November/2004 and January, March, May and August/2005. A total of 283 taxa was identified. Zygnemaphyta was the most specious group, followed by Chlor...
متن کاملLarge CO2 disequilibria in tropical lakes
[1] On the basis of a broad compilation of data on pCO2 in surface waters, we show tropical lakes to be, on average, far more supersaturated and variable in CO2 (geometric mean ± SE pCO2 = 1804 ± 35 matm) than temperate lakes (1070 ± 6 matm). There was a significant negative relationship between pCO2 and latitude, resulting in an average decrease of pCO2 by 2.8 ± 0.5% per degree latitude. In ad...
متن کاملOrganic carbon burial efficiency in a subtropical hydroelectric reservoir
Hydroelectric reservoirs bury significant amounts of organic carbon (OC) in their sediments. Many reservoirs are characterized by high sedimentation rates, low oxygen concentrations in bottom water and a high share of terrestrially derived OC, and all of these factors have been linked to a high efficiency of OC burial. However, investigations of OC burial efficiency (OCBE, i.e., the ratio betwe...
