We examined the storage dynamics and isotopic composition of soil water over 12 months in three hydropedological units in order to understand runoff generation in a montane catchment. The units form classic catena sequences from freely draining podzols on steep upper hillslopes through peaty gleys in shallower lower slopes to deeper peats in the riparian zone. The peaty gleys and peats remained...

Elemental analyses (H, N, C, O, S), bulk isotope analyses (C, N) and C content of pyrolysis products from Sphagnum moss, underlying peat from a bog and the bog water (Hohlohsee, Black Forest, Germany) were performed to identify humi®cation processes in the early diagenesis of peat formation and to determine the origin of dissolved organic matter (DOM) in the bog lake. Atomic ratios of bulk elem...

This article reports the first discovery of middle Holocene cryptotephra from a peat sequence in Estonia, eastern Baltic. Two sequences, Mustjärve and Parika (located 110 km apart), were chosen for a pilot study aimed at finding traces of tephra fallout during the middle Holocene. Peat accumulation at both sites started in the early Holocene (c. 9500 9000 C yr BP; c. 11 000 10 000 cal. yr BP) a...

Global warming can substantially affect the export of dissolved organic carbon (DOC) from peat-permafrost to aquatic systems. The direct degradability of such peat-derived DOC, however, is poorly constrained because previous permafrost thaw studies have mainly addressed mineral soil catchments or DOC pools that have already been processed in surface waters. We incubated peat cores from a palsa ...

Indonesian peatland, one of the world’s largest tropical peatlands, is facing immense anthropogenic pressures such as illegal logging, degradation and also peat fires, especially in fertile peatlands. However, there still is a lack of appropriate tools to assess peatland land cover change. By taking Pelalawan district located in Sumatra Island, this study determines number of land cover endmemb...

We are investigating how sensors can improve a portable reminder system (PEAT) that helps individuals accomplish their daily routines. PEAT is designed for individuals who have difficulty remembering when to perform activities because of cognitive impairments from strokes or other brain injuries. These impairments can cause a significantly reduced quality of life for afflicted individuals and t...

Peat moss is the most widely used source of organic matter for growing horticultural crops in the United States. The demand for peat as a substrate constituent for bedding and pot plants has remarkably increased in recent years, thus reducing the availability and increasing cost (Nappi and Barberis, 1993). Composts may serve as qualitatively and economically as competitive alternative sources o...

Stable Zn isotopes fractionation was studied in main biogeochemical compartments of a pristine larch forest of Central Siberia developed over continuous permafrost basalt rocks. Two north- and south-oriented watershed slopes having distinctly different vegetation biomass and active layer depth were used as natural proxy for predicting possible future climate changes occurring in this region. In...
