TL;DR: In this paper, water samples from the catchment area and Lake Karakul, and a 104-cm sediment core from its shallow eastern sub-basin, were investigated and provided a first lake record from the region spanning the last 4200-cal yr BP.

TL;DR: The carbon stable isotopic value of dissolved inorganic carbon (δ13CDIC) was measured over several years at different depths in the water column in six carbonate-precipitating temperate lakes as discussed by the authors.

TL;DR: In this article, the authors explore an alternative model where Mn-carbonates form in redox-stratified water columns linked to calcium carbonate dissolution, and demonstrate that sedimentary Mn enrichments may develop from primary carbonate phases, and can occur in environments with dissolved oxygen concentrations 200 μM.

TL;DR: In this article, a review of plant macrofossils for radiocarbon dating is presented, with a particular focus on the uptake of reservoir-aged dissolved inorganic carbon (DIC) by emergent plants.

TL;DR: Wild rice seedling emergence, seedling survival, biomass growth, viable seed production, and seed mass all declined with sulfate additions and hence sulfide concentrations in sediment and wild rice populations became extinct in most tanks with concentrations of 250 mg SO4 /L or greater in the overlying water.
