This repository contains links to the sources for a large range of spatial datasets. It is updated every now and again, but is not an exhaustive list by any means! There are other spatial data sources not listed here which you can search for and find yourself (you can always speak to st...
The gamma-ray source consists of a small iridium sheet (0.2 mm×4 mm×10 mm) shielded by a uranium box and made radioactive by neutron activation to an activity of about 1 TBq (100 Ci). The radioisotope I77192r thus generated decays with a half-life of 74 days into excited levels ...

Samples were collected on 18 March 2014 from a sea ice-covered fjord, Kobbefjord in the vicinity of Nuuk, Greenland (64°07′N, 51°21′W) with no close source of human activity (around 15 km). Due to logistical issues, air sampling was performed on the adjacent coast using a 0.1...
Nevertheless, since 1969 (Peterle, 1969) signs of global pollution (pesticide – dichlorodiphenyltrichloroethane, DDT) have been noted at detectable levels in snow. The cryosphere encompasses all surfaces that contain water in solid form, as snow and ice surfaces, which cover approximately 98% of...
series, retrieved from the Antarctic ice core at the WAIS (West Antarctica Ice Sheet) Divide/Marie Byrd Land60, which details the time sequence of major volcanic eruptions. Many of the volcanic events that comprise the ice core database60refer to Chilean volcanic eruptions and therefore ...
To recover microplastics from bulk or volume-reduced water samples, a sieving or filtration step is commonly used. Alternatively, microplastics have been collected from the surface of the water sample using tweezers. Yet, there is a high likelihood of bias when visually collecting microplastics [11...
For some specific source categories, especially the activity related sources, the quantitative contribution of pollutants cannot be allocated to specific sources because of several sources producing simultaneous pollutant contributions to the same mass of runoff water, or because of high unpredictability, e...
