Automating long-term glacier dynamics monitoring using single-station seismological observations and fuzzy logic classification: a case study from Spitsbergen
Retreating glaciers are a consequence of a warming climate. Thus, numerous monitoring campaigns are being carried out to increase understanding of this on-going process. One phenomenon related to dynamic glacial changes is glacier-induced seismicity; however, weak seismic events are difficult to record due to the sparse seismological network in arctic areas. We have developed an automatic proce...
متن کاملVariability of Water Chemistry in Tundra Lakes, Petuniabukta Coast, Central Spitsbergen, Svalbard
Samples of water from small tundra lakes located on raised marine terraces on the eastern coast of Petuniabukta (Ebbadalen, Central Spitsbergen) were examined to assess the changes in water chemistry that had occurred during the summer seasons of 2001-2003 and 2006. The unique environmental conditions of the study region include the predominance of sedimentary carbonate and sulphate rocks, low ...
متن کاملComparison of the "small” Spout with the Traditional 7/16” Spout
The "small” spout, 19/64” or 5/16” in diameter, has been widely available to maple producers since the mid to late 1990's as a "healthy" alternative to the traditional 7/16” spout. While now in general use by producers in some regions, particularly those collecting sap by vacuum, the utility of these smaller spouts is still questioned by many sugarmakers, particularly those collecting sap by gr...
متن کاملAn Arctic char observed in a glacial Spitsbergen river
An anadromous Arctic char (male) was recorded in southwestern Spitsbergen, in a very muddy glacial river, in August 2008. This is apparently the first specimen of this species observed in such an unfavourable habitat in Svalbard. Arctic char (Salvelinus alpinus), the only freshwater native fish in Svalbard, is rather common (occurring in more than 100 lakes and watercourses) and is differentiat...
متن کاملSynapse Formation: Astrocytes Spout off
Trillions of synapses form as the brain develops. This intimate contact between two neurons has now been shown to be facilitated by thrombospondins - large extracellular matrix proteins secreted by astrocytes.
