Science Frontiers ONLINE No. 35: Sep-Oct 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects An Extraordinary Peat Formation Most of Beauchene Island, in the Falklands, is covered with a tussock-forming grass. During the past 12,500 years, a deep accumulation of exceptionally dense peat has formed. The basal peat is lignitic, but is several hundred times too young to be a true lignite. This peat does not decay as rapidly as it should, given its populations of bacteria, yeasts, and other fungi. The peat accumulates about ten times faster than in other peat-forming regions. The authors conclude that the peat-forming process is poorly understood. (Smith, R.I . Lewis, and Clymo, R.S .; "An Extraordinary Peat-Forming Community on the Falkland Islands," Nature, 309:617, 1984.) Comment. If we do not understand how present-day peat forms, how can we be so dogmatic about coal-forming processes millions of years ago? From Science Frontiers #35, SEP-OCT 1984 . 1984-2000 William R.

... albeit rather erratically. The slow heaving of their surfaces is a poorly understood phenomenon as the following abstract demonstrates. The surfaces of bogs and fens in northeastern Minnesota may rise and fall by as much as 36 cm in a single day. This phenomenon, known as Mooratmung, or bog breathing, has been traditionally attributed to changes in water storage. However, the surface deformations recorded by static GPS [Global Positioning System] stations on bog and fen sites within the Red Lake peatland are more frequent and out of phase with precipitation events. These vertical fluctuations instead appear to be related to a complex interplay among climate, hydrology, and microbial gas-production. Climate-driven re-charge on bogs, for example, stimulates the production of biogenic gases by advecting root exudates deep into the peat profiles. Seasonal droughts, however, favor the formation of transient confining layers that trap biogenic gases into discrete pockets... Bog breathing may therefore be a surface manifestation of the accumulation and release of greenhouse gases in peat deposits. (Glaser, Paul H. et al; "Bog Breathing: the Curious Interplay of Climate, Ground-water, and Greenhouse Gases in Boreal Peatlands," Eos, 80:F47, 1999.) Spontaneously igniting, biogenic gases are found in many marshy places. These eruptions were observed on an English mud flat in 1902. Comment. When bogs breathe they release plumes of flammable gases which probably give rise to the many observations of will-o '- the-wisps in marshy areas. Why these gas clouds are luminous remains mysterious. ...

... small (0 .131-gram) steel ball bearings at an ice tar-get made with 99.9 % deuterium. Despite the violent shattering of the deuterated ice, no significant numbers of neutrons were measured. (Sobotka, L.G ., and Winter, P.; "Fracture without Fusion," Nature, 343:601, 1990.) Comment. Whatever the fate of fractofusion, several labs around the world are still pursuing cold fusion. The sci entific mainstream, though, considers cold fusion a dead issue, even though anomalous neutrons and heat emission have been found in several experiments. We are happy to report, however, that cold fusion has definitely generated its first book: Cold Fusion : The Making of a Scientific Controversy, F.D . Peat.

... in diameter, but the largest is 2 kilometers across. Basically, they are annuli of sparse growth amid dense stands of trees both inside and outside the rings. The barren rings -- some 2,000 have been found -- appear light-colored against the dark green of the healthy forest growth. Why don't trees grow well within the rings, and why the neat circles? At first expanding rings of fungus infection were suspected, something perhaps like the fungus that creates those fairy rings on lawns. But no fungus has been found on the tree roots. One curious fact was discovered about the soil where tree growth is sparse. The soil constituting the rings is poorly drained and is depressed 1-2 meters below the surrounding healthy forest. These circular depressions support mainly peat and tamaracks. But what causes these ring-shaped depressions? One theory holds that the rings are the suface expressions of diamond-bearing kimberlite pipes, like those in South Africa. A few prospectors are already staking diamond-mine claims! Another theory supposes that the rings are created by huge, natural electrical batteries that exist in the carbonate soil. The current flow supposedly creates acidic conditions that eats away at the soil causing it to slump in a circle around one terminal.
