A calculation of the number of annual layers is used for the geochronology of glacial and postglacial ages.
Late Glacial vegetation, sedimentation and ice recession chronology in the surroundings of Lake Prossa, central Estonia/Taimestik, sedimentatsioon ja jaa taandumise kronoloogia Hilis-Glatsiaalis Prossa jarve umbruses Kesk-Eestis up to 30 cm thick (alternating varved horizontal layers of brown clays and grey silty layers) are located in the nearshore, whereas below the sand accretion terrace on the bottom surface there are traces of submarine erosion, indicating sediment transport in NW direction.
So, take a stroll down memory lane to remember all of our past Word of the Year selections.
Radiocarbon calibration based on dendro-chronology and U-series dated corals yield a calibration curve (INTCAL98) well into the Late Glacial, back to ca. Beyond this limit, various calibration curves are produced, mainly based on laminated sediments and various carbonates dated by U-series isotopes.
Swedish pioneer Baron Gerard de Geer discovered in the late 19th century that these could be counted and correlated or linked over long distances, which gave him a timescale of 12,000 years and fixed the end of the Ice Age at about 10,000 years ago.
CATEGORY: technique DEFINITION: A technique for producing chronometric dates based on the annual formation of layers of sediment on lake and river beds in glacial regions.
Please note that this trope applies when a creator (writer, director, etc.) ceases work on a project, not a participant (actor, well... Also note that since all creators are mortal, this is not merely when creators die, it's when they die with works still in progress.
Each calibration method (other than dendro-chronology) has its own assumptions and pitfalls.
Our Word of the Year choice serves as a symbol of each year’s most meaningful events and lookup trends.
It is an opportunity for us to reflect on the language and ideas that represented each year.
During the summer, melting accelerates, melt-water streams flow faster and carry more material.
The supply of sediment to the ice-marginal lake varies with the season.
If readers are lucky, the author had enough warning or foresight to keep notes on their plans for the rest of the series or at least fill someone else in on the most relevant plot points, so that their work can be continued by another author, or possibly even several.
