“…The likely influence on these concentrations is a mixture of natural processes and human activity located far away from the catchment (Bazzano et al 2014). In particular, a natural source of metals could be the volcanic eruptions in Iceland (Karasiński et al 2014;Tepe and Bau 2014). Karasinski et al (2014) has indeed shown that the transport of volcanic dusts and aerosols towards Svalbard has occurred in both 2010 (from the Eyjafjallajokull eruption at 63.63°N 19.62°W) and 2011 (when Grimsvotn erupted at 64.42°N 17.33°W).…”

“…Zn and Pb are an exception here-it was shown that the levels of those elements are very high. An additional factor worth considering is the occurrence of two major volcanic eruptions in Iceland the years 2010-2011, which could influence the trace element supply to Svalbard via dust deposition from long-range transport (Langmann et al 2010;Karasiński et al 2014;Tepe and Bau 2014).…”

“…Svalbard Archipelago's relatively close location to the European Continent makes this sensitive region particularly exposed to the influence of the pollutants, emitted from the industrial European countries (such as the European part of Russia, Norway, Great Britain) (Kozak et al 2013;Polkowska et al 2011), as well as the impact of natural-based causes-like forest and agricultural fires (Cahill et al 2008;Stock et al 2008;Nawrot et al 2016), glacial runoff (Bazzano et al 2014;Stachnik et al 2016) or volcanic eruption (Iceland) (Langmann et al 2010;Karasiński et al 2014;Rose et al 2006).…”

Arctic regions experience metal pollution, despite their remote location, and the distribution and migration of those metals determine their potential impact on the local environment. Here, a High-Arctic catchment (Revelva, Svalbard) located remotely from human-induced pollution sources is studied with respect to the distribution and migration of chosen trace elements (Ag, Al, As, B, Ba , the highest mean-weighted concentration noted for Sr (42.5 lg L -1 ). The concentrations in the river water were likely influenced by both natural and human-activity-related processes. These factors can produce substances of the same chemical composition (e.g. carbon dioxide, sulphur dioxide and metals may be emitted both by a volcanic eruption and by industrial sources). Therefore, chemometric techniques were used in the current paper to distinguish the multiple sources of pollution in the Revelva catchment. The authors were seeking to determine whether there is indeed evidence for contamination, sufficient to cause environmental damage in polar region. As a result, it was shown that the long-range transport could play an important role in shaping the metal concentration profile of this Arctic tundra environment, capturing both the influence of volcanic eruptions within the region and the human activity in a range of distances from the study site.

“…It is highly probable that the pollutants in the eruption clouds were deposited in the region of the Arctic. The Polish Polar Research Station at Hornsund fjord (Spitsbergen, 77.00 • N, 15.33 • E), equipped with light detection and ranging system (LIDAR), registered changes in the atmosphere (aerosol, volcanic dust) at various altitudes, which emphasizes the scale of both eruptions [48]. Nevertheless, when discussing the process of pollution deposition in the specific components of the environment, one may not ignore the key role of meteorological factors (air temperature, air humidity and precipitation, atmospheric pressure, air movement, insolation).…”

“…Observations of aerosol formed in the volcanic eruption, were conducted at the Polish Polar Station in Hornsund on 18 and 25 May 2010 (Eyjafjallajökull), and 25 May 2011 (Grímsvötn) [48]. In both said cases minor amounts of aerosol, in relatively thin layers (~200 m), were observed at an altitude of over 2 km, which precludes material deposition on the surface of Earth.…”

Abstract:The paper presents changes in concentration levels of dioxin-like compounds that can be observed over the course of four study seasons in water samples collected from the Arctic watershed of Svalbard. The conducted analysis involved anthropogenic and natural factors that may affect the concentration of PAHs in the study samples of water. An attempt is made to indicate the emission source of the compounds being deposited and to identify the extent to which the substances under analysis actually affect the Arctic ecosystems. Moreover, the work employs the following: diagnostic ratios PAHs, air masses backward trajectory analysis, Lidar observations and land relief analysis in order to provide a multi-level interpretation of the obtained data. Natural environment constitutes a complex system of subtle correlations that need to be perceived as a dynamic medium, in which multi-faceted processes take place.

Quantification of volcanic cloud top heights and thicknesses using A‐train observations for the 2008 Chaitén eruption

New evidence of vertically thin (< 400 m), low‐level (< 10 km) volcanic ash clouds, as well as confirmation of previously reported high‐level (>10 km) ash clouds, from the May 2008 Chaitén eruption in southern Chile is presented. A‐train remote sensors were used to measure high‐resolution volcanic cloud top heights (VCTHs) during the explosive phase (2–10 May 2008) of the eruption. Ash clouds were identified using a reverse absorption technique applied to hyperspectral measurements taken by the Atmospheric Infrared Sounder. Once identified, heights and thicknesses were derived from the Cloud‐Aerosol Lidar with Orthogonal Polarization (CALIOP) instrument. As these two instruments are part of the same constellation of satellites, coincident retrievals are routinely possible. Collocation of the data allowed for detection of volcanic ash within CALIOP profiles. Using a simple thresholding algorithm, VCTH and thickness were derived from the CALIOP profiles. A total of 12 VCTH measurements, ranging from 3.7 to 16.6 km, have been derived. Back trajectories from the Hybrid Single Particle Lagrangian Integrated Trajectory dispersion model were used as a check on volcanic origin of the detected ash clouds. Ensemble forward trajectories were generated to demonstrate how the new data could be used to improve Volcanic Ash Advisory Center operations. The findings reported here demonstrate several cases where low‐level ash was not recorded previously and include observations of thin ash clouds at large distances (∼4000 km) from the volcano.
