“…Some of the highly used radionuclides include; 137 Cs, 210 Pb and 7 Be (Dercon et al, 2012;Porto et al, 2014a). In applying these nuclides, selection of a reference site is of critical importance.…”

“…Gellis et al (2006), Walling (1998), Mahawatte and Abeynayake (2010) observed that there is a strong adsorption of 137 Cs by clay and organic matter in soils. According to Patrocinio and Andrello (2009) and Dercon et al (2012) 137 Cs is useful in studying the sediment chronology since it is rapidly and strongly absorbed to fine particles of the soil. Also, the distribution of 137 Cs in the soil sediment profile is directly related to the chronology of sediment deposition.…”

“…In addition, soil erosion is reported by Collins et al (2001) as a serious environmental problem in many African countries. The severe soil erosion and degradation largely affect food security in Sub-Saharan Africa (Dercon et al, 2012). This has been attributed to many developing countries in Africa having experienced expansion of agriculture on to marginal land.…”

“…In addition, in most developing countries especially in Africa, continuous sediment gauging has not been done consistently for longer periods. To tackle these challenges, FRNs have been adopted in many developed countries to assess soil erosion magnitudes (Zapata and Agudo, 2000;Dercon et al, 2012;Porto and Walling, 2012) but little has been done in Africa. Therefore, there is need to explore the use of FRNs in assessing soil erosion rates and patterns of soil redistribution/deposition.…”

Soil erosion is one of the main soil degradation phenomena that threaten sustainable use of soil productivity thus affecting food security. In addition, it leads to reservoir storage capacity loss because of sedimentation. This not only affects water quantity but also water quality. Worldwide, annual loss in reservoir storage capacity due to sedimentation is 0.5 to 1%. Similarly, about 27% of land in Africa is largely degraded by erosion. As a result, there is need to minimize soil erosion and deposition through site specific estimation of soil erosion and deposition rates in the reservoirs. To achieve this, Fallout RadioNuclides (FRNs) are some of the methods in use. The most common radionuclides include; 137 Cs, 210 Pb and 7

In the current work a new method to extract and analyse pore water d 2 H and d 18O from drill core samples via H 2 O (liquid) -H 2 O (vapour) equilibrium laser spectroscopy is presented. The method combines a H 2 O (liquid) -H 2 O (vapour) equilibrium cell with a Los Gatos Research (LGR) cavity ring down mass spectrometer (CRDS) and follows and adaption of the original method presented by Wassenaar et al. (2008). Sediment and rock samples taken from a research site in New South Wales, Australia were first equilibrated in a fixed volume of dehumidified air and then directly sampled by the LGR mass spectrometer. Results provide clear evidence that the technique is repeatable and can be conducted on geologic media that contain volumetric water content as low as 5%, with H 2 O (liquid) -H 2 O (vapour) equilibrium occurring over time periods as short as 120 minutes. The faster sample analysis time and lower associated consumable and instrumentation costs of the method compared to conventional techniques for pore water extraction (centrifugation, squeezing, installation of monitoring bores, etc.) and analysis therefore presents great potential for field deployment, enabling hydrogeological profiling without the need to remove drill core samples from site.

These rare natural gas seeps provide opportunities for direct sampling of gas from subsurface hydrocarbon accumulations without the need for drilling or other costly means of petroleum exploration.We have documented a site in the northern Appalachian Basin, at Chestnut Ridge County Park, New York (Fig. 1, left), where gas seepage has supported a spectacular "eternal flame" throughout available recorded history, and which may have burnt naturally for many hundreds or even thousands of years. This remarkable flame marks a natural gas macroseep of dominantly thermogenic origin. Gas emanates directly from deep shale source rocks, probably the Rhinestreet Shale of the Upper Devonian West Falls Group, which makes this a rare case in contrast to most petroleum seepage systems where gas derives from conventional reservo...

Soil erosion has become one of the most common environmental problems and threatens food security. This study assessed the short‐term effect of tillage and mulch on soil redistribution using the beryllium‐7 method, soil moisture distribution, and soil organic carbon loss through soil erosion in typical agroecological conditions of Benin. The experiment was conducted on acrisols (at Dan) and ferralsols (at Za‐zounmè) in central Benin. Three tillage practices slope ridging (SR), contour ridging (CR), and no‐tillage (NT), and three mulch doses 0 (0 M), 3 (3 M), and 7 t ha−1 (7 M) on soil erosion under maize were investigated. The results showed a tillage and mulch interaction significantly (p < 0.05) influencing the soil redistribution, the loss of total carbon, the carbon of the particulate organic matter (C_POM), and the carbon content of the fine organic matter (C_MOM). High soil erosion was observed under SR0M (−10.19 t ha−1) at Dan and under NT0M (−7.36 t ha−1) at Za‐zounmè. NT7M (0.80 t ha−1), SR7M (0.69 t ha−1), CR3M (2.07 t ha−1), and CR7M (4.05 t ha−1) showed deposition at Dan, while SR7M (0.23 t ha−1), NT7M (1.69 t ha−1), and CR7M (3.93 t ha−1) showed deposition at Za‐zounmè. C_MOM was lost on both sites. Mulch increases soil moisture for all three tillage treatments, and this effect is well pronounced especially if the amount of mulch is great. This study revealed useful information to be taken into consideration when developing soil and water conservation management strategies in Benin.
