Radiocarbon in annual coral rings of Florida [PDF]
Geophysical Research Letters, 1978 Radiocarbon measurements on a 175‐year (A.D. 1800 to 1974) growth of the coral Montastrea annularis from The Rocks reef off the Florida Keys reveal the rate of local uptake of fossil fuel CO2 and bomb 14C by surface ocean waters of the Gulf Stream. In the nineteenth century, the pre‐bomb, pre‐industrial Δ14C value of surface ocean waters as seen in ...

Using the International Tree-Ring Data Bank (ITRDB) records as century-long benchmarks for global land-surface models [PDF]
Geoscientific Model Development, 2021 The search for a long-term benchmark for land-surface models (LSMs) has brought tree-ring data to the attention of the land-surface modelling community, as tree-ring data have recorded growth well before human-induced environmental changes became ...

Influence of Growth Ring Number and Width on Elastic Constants of Poplar
BioResources, 2023 The objective of this work was to evaluate the effect of growth ring number (specimens including 2, 4, and 6 rings from the bark) and growth ring width on elastic constants in the radial direction of Populus x canadensis, which has not been revealed ...

Xylogenesis of Scots Pine in an Uneven-Aged Stand of the Minusinsk Depression (Southern Siberia) [PDF]
Журнал Сибирского федерального университета: Серия Биология, 2020 Tree-ring formation studies are important for assessing the impact of environmental factors on tree growth at intra-seasonal resolution. This information is necessary for understanding plant acclimatization to current and expected climate changes. Little

Annual Rings of Growth in Carboniferous Wood [PDF]
Botanical Gazette, 1921 In a discussion of anatomical structure and climatic evolution, JEFFREY, emphasizes the absence of annual rings in Cordaitean wood from the Carboniferous in latitudes south of England as indicative of uniformity of climate, in contrast with the conditions in the Triassic period, in which coniferous wood with annual rings is found as far south as ...
