Deep carbon storage potential of buried floodplain soils.
Soils account for the largest terrestrial pool of carbon and have the potential for even greater quantities of carbon sequestration. Typical soil carbon (C) stocks used in global carbon models only account for the upper 1 meter of soil. Previously unaccounted for deep carbon pools (>1 m) were generally considered to provide a negligible input to total C contents and represent less dynamic C pools. Here we assess deep soil C pools associated with an alluvial floodplain ecosystem transitioning from agricultural production to restoration of native vegetation. We analyzed the soil organic carbon (SOC) concentrations of 87 surface soil samples (0-15 cm) and 23 subsurface boreholes (0-3 m). We evaluated the quantitative importance of the burial process in the sequestration of subsurface C and found our subsurface soils (0-3 m) contained considerably more C than typical C stocks of 0-1 m. This deep unaccounted soil C could have considerable implications for global C accounting. We compared differences in surface soil C related to vegetation and land use history and determined that flooding restoration could promote greater C accumulation in surface soils. We conclude deep floodplain soils may store substantial quantities of C and floodplain restoration should promote active C sequestration

Tendencies, determinism, and sporting prowess – a response to Mumford and Anjum
Abstract: In Getting Causes from Powers (2011) Stephen Mumford and Rani Anjum published a novel approach to the metaphysics of dispositional properties, according to which causal powers are to be viewed as vectors. More recently they have employed a similar system to represent prowess in sport. In this paper l discuss the Mumford/Anjum ‘tendential theory of sporting prowess’. I question their motivation for the tendencies account, concluding (contra Mumford and Anjum) that a belief in determinism would not take away from the enjoyment of spectator sports. Nonetheless, I deem the tendential theory of prowess plausible. In addition to criticising their motivation, then, I develop the Mumford/Anjum thesis, applying the multi‐dimensional aspect they themselves apply to ‘complex causal situations’, to the metaphysic of sporting prowess

Bibliography to Upper Mississippi River Aquatic and Wetland Plant Literature
A comprehensive bibliography of 308 references by 270 authors was prepared to provide access to the literature on aquatic and wetland plants of the Upper Mississippi River. The references treated the taxonomy, floristics, ecology, wildlife biology, limnological role, and management programs on macrophytes present in the navigation channel, backwater, and floodplain of the Upper Mississippi River, which stretches from Minneapolis, MN, southward some 1,380 km to Cairo, IL. Articles, serials, books, agency reports, agency contracted studies, theses, and dissertations were included
Optics in the Schwarzschild space-time
Realistic modelling of radiation transfer in and from variable accretion
disks around black holes requires the solution of the problem: find the
constants of motion and equation of motion of a light-like geodesic connecting
two arbitrary points in space. Here we give the complete solution of this
problem in the Schwarzschild space-time.Comment: 14 pages, 10 figures, type C orbits added, analytic solutions for
time of flight of photons for all 3 types of orbits adde
