these features indicate that the temporal structure of our brGDGT-based reconstruction reflects actual temperature trends through time. However, the magnitude of inferred continental temperature variation (total MST range 16–
The Temperature 12k database gathers paleotemperature data from every continent and ocean. The geographical distribution of the records, however, is uneven (Fig.2). Latitudinally, 51% of the sites are located within the zone of 60–30°N, and only 16% are located in the Southern Hemisphere ...
So I have started including the chart below as well. Note that it is in Fahrenheit (vs. the anomaly chart above in Celsius) because US audiences have a better intuition for Fahrenheit, and is only for the US vs. the global chart above. It shows the range of variation in US monthly av...
close to the northern part of the Atlantic Ocean (Figure1). The Arctic Ocean, the Atlantic Ocean, the Baltic Sea, the Scandinavian mountain range, latitudinal gradients, and continental Eurasia are the most important geographical
The value of the Kappa coefficient varies in the range from −1.0 to 1.0, with 1.0 interpreted as the perfect agreement of the data (user-assigned and predefined values match each other), 0.0 interpreted as an agreement no better than that expected by chance, and negative values interpreted...
Average temperatures for December at major cities throughout Europe are listed below in degrees Celsius and Fahrenheit.The cities range from Amsterdam to Zurich and from Reykjavík to İstanbul. They are listed alphabetically and you can jump ahead to the section for Amsterdam to Kiev, Leeds to ...
which predict melt-fluid fractionation in the range of -2 ± 1‰ for igneous temperature above 1100 °C (Sanchez-Valle et al.2005; Li et al.2020,2021). Consequently, in this contribution we investigated experimentally the B isotope fractionation in fluid-saturated MORB compositions at high...
Materials and methods Study site The study was conducted in four first- and second- order streams in the Hengill area between 27 July and 14 August 2006. The Hengill area is situated 30 km east of Reykjavik, Iceland (64°030N: 021°18W). The study streams are a subset of a larger ...
and other archives. They range in length from 50 to 2000 years, with a median of 547 years, while temporal resolution ranges from biweekly to centennial. Nearly half of the proxy time series are significantly correlated with HadCRUT4.2 surface temperature over the period 1850–2014. Global temp...
Using basalts from Eyjafjallajökull volcano (Iceland) we show that contraction during cooling induces stress build-up below the solidus temperature (980 °C), resulting in localised macroscopic failure between 890 and 840 °C. This temperature window for incipient columnar jointing is ...
