A single expulsion by one bobtail squid produces enough bacterial symbionts to fill 10,000m3 of seawater at a concentration that is comparable to what is found in coastal waters.

Luminescence dating: Luminescentie datering nauwkeurigheid

Fisher, Andrew.; Thompson, Thomas.; Thoden, James.; Baldwin, Thomas.; Rayment, Ivan. 1, these bacteria may be free living (such. 13 Though bio-luminescence across a diverse range of organisms such as bacteria, insects, and dinoflagellates function in this general manner (utilizing luciferase and lucifierin there are different types of luciferin-luciferase systems. Luminescence dating refers to a group of methods of determining how long ago mineral grains were last exposed to sunlight or sufficient heating. It is useful to geologists and archaeologists who want to know when such an event occurred. Luminescence dating is a geochronological tool used to determine the timing of sediment burial, pottery firing, mountain evolution, mineral formation and the exertion of pressure. The luminescence dating technique covers a large age range from modern-day to millions of years. Luminescence dating typically refers to a suite of radiometric geologic dating techniques whereby the time elapsed since the last exposure of some silicate minerals to light or heat can be measured. Optische gestimuleerde luminescentie (OSL) datering is een relatief nieuwe datering stechniek die is ontwikkeld uit de meer bekende thermo luminescentie (TL) methode. Ontwikkelingen in de laatste jaren hebben de methode betrouwbaarder en breder toepasbaar gemaakt. Faciliteiten voor optische datering bij de TUDelft maken de methode toegankelijk. Luminescence dating might be limited if the sediment to be measured has been heterogeneously exposed to light prior to being buried and shielded from daylight.
