A New Attempt to Establish the International Radiocarbon Soils Database (IRSDB)
Twenty years after the first International Radiocarbon Database Workshop, and 13 yr after the setup of a preliminary structure for a worldwide database on 14 C dates of soils, sound reasons and excuses for not establishing a real and globally accessible database have diminished. Climate change itself is widely accepted as reality now, and the strong demand of the modeling community for reliable data of the carbon pool—especially in soils—has been…
C-Dated Charcoal and Sediment Drilling Cores as First Evidence of Holocene Tsunamis at the Southern Spanish Coast
At 2 locations of the southern Spanish coast, we found indications for tsunamis induced by submarine earthquakes. Charcoal, which we sampled in 2 stratified, assumed tsunamigenic sediment (tsunamites) layers at the shore outside the ruins of the Roman city of Baelo Claudia, close to the Strait of Gibraltar (province of Cádiz), and radiocarbon dated, surprisingly turned out to be of identical age, about 465 BP. In the laguna of the Cabo de Gata (p…
Carbon Dynamics in Vertisols as Revealed by High-Resolution Sampling
Two Vertisol soil profiles under xeric soil moisture regimes, located at Qedma and Akko, Israel, were investigated and compared to a profile under ustic moisture regime, located in Hyderabad, India. Samples were taken in complete successive 2 cm thin layers down to about 180 cm depth or more. Organic and inorganic carbon were analyzed with regard to 13 C and 14 C concentrations. While all soils have radiocarbon ages of several thousand years BP, …

Hamburg Radiocarbon Thin Layer Soils Database
We report here the remainder of the Hamburg University dates on thin soil layers (HAM 1652–3129)
Requirements for An International Radiocarbon Soils Database
Up to now, Global Carbon Cycle Models (GCCM) have only represented the soil and biosphere in a very simplified way. For example, the High Resolution Biosphere Model (HRBM) (Esser 1987; Esser and Lautenschlager 1994) distinguishes five subreservoirs and determines the fluxes between them for selected area of a global grid. The models have not yet been sufficiently tested against global observations. Such testing is difficult because the observed v…

The Use of Natural 14 C and 13 C in Soils for Studies on Global Climate Change
Some examples are given to show that the depth distribution curves of natural 14 C and 13 C of thin-layer sampled soil profiles can be used for inferring changes in soil organic matter and climate changes. By using a simple exchange model, we can determine whether decomposition products are fixed by clay or transported downward toward the groundwater table. We can also estimate the amount of the Greenhouse gases, CO 2 and CH 4 , produced by the d…
Twenty-Five Years of Radiocarbon Dating Soils
Soil organic matter sequesters close to three times the carbon existing totally in the living biomass and nearly the same for the total carbon in the atmosphere. Models, such as Jenkinson's or Parton's Century model, help to define soil organic matter fractions of different functions, based on residence time/ 14 C age. Rejuvenation of soil carbon was felt to be the principal impediment to absolute soil dating, in addition to the ambiguity of the …

Carbon Isotope Dynamics in Some Tropical Soils
We determined δ 13 C and D 14 C in some agricultural soil profiles of the tropics: Ustalf from the semi-arid tropics (India), a Udult, an Aquoll and an Aquept from the humid tropics (Philippines). We used a thin-layer sampling, resulting in high-resolution depth-distribution patterns of natural 13 C and 14 C content of organic carbon. Regular plowing or puddling leads to uniform isotope concentrations in the topsoil. Decomposition of organic matt…
Shifts in 14C Patterns of Soil Profiles Due to Bomb Carbon, Including Effects of Morphogenetic and Turbation Processes
Principles contributing to changes and the final balance of rejuvenation in 14 C dates of soil profiles are identified. The annual addition to the atmosphere of ca 5.5·10 12 kg of dead carbon from fossil carbon sources and 1.5·10 12 kg of older carbon from forest clearing make soil appear older. Bomb carbon and annual recycling of most of the 115·10 12 kg of terrestrial organic carbon, equivalent to the annual photosynthetic turnover of carbon, r…
Thin Layer δ 13 C and D 14 C Monitoring of “Lessive” Soil Profiles
The natural 14 C and 13 C content of soil organic matter and their dependence on depth for two Alfisols are presented. This soil type which covers a large area of the earth's surface is characterized by clay migration processes (“Lessivé”). The samples were taken as successive horizontal layers of 2cm depth from an area of ca lm 2 size as deep as the C content allows 14 C analysis. The minima of the D 14 C distribution decrease with depth, while …
