Historic records of organic compounds from a high Alpine glacier: influences of biomass burning, anthropogenic emissions, and dust transport

Historic records of α-dicarbonyls (glyoxal, methylglyoxal), carboxylic acids (C6–C12 dicarboxylic acids, pinic acid, p-hydroxybenzoic acid, phthalic acid, 4-methylphthalic acid), and ions (oxalate, formate, calcium) were determined with annual resolution in an ice core from Grenzgletscher in the southern Swiss Alps, covering the time period from 1942 to 1993. Chemical analysis of the organic compounds was conducted using ultra-high-performance liquid chromatography (UHPLC) coupled to electrospray ionization high-resolution mass spectrometry (ESI-HRMS) for dicarbonyls and long-chain carboxylic acids and ion chromatography for short-chain carboxylates. Long-term records of the carboxylic acids and dicarbonyls, as well as their source apportionment, are reported for western Europe. This is the first study comprising long-term trends of dicarbonyls and long-chain dicarboxylic acids (C6–C12) in Alpine precipitation. Source assignment of the organic species present in the ice core was performed using principal component analysis. Our results suggest biomass burning, anthropogenic emissions, and transport of mineral dust to be the main parameters influencing the concentration of organic compounds. Ice core records of several highly correlated compounds (e.g., p-hydroxybenzoic acid, pinic acid, pimelic, and suberic acids) can be related to the forest fire history in southern Switzerland. P-hydroxybenzoic acid was found to be the best organic fire tracer in the study area, revealing the highest correlation with the burned area from fires. Historical records of methylglyoxal, phthalic acid, and dicarboxylic acids adipic acid, sebacic acid, and dodecanedioic acid are comparable with that of anthropogenic emissions of volatile organic compounds (VOCs). The small organic acids, oxalic acid and formic acid, are both highly correlated with calcium, suggesting their records to be affected by changing mineral dust transport to the drilling site.

Wie rasch ändert sich die Waldvegetation als Folge von raschen Klimaänderungen?

How rapidly does forest vegetation change due to rapid climatic change? Current predictions of future climates show a global increase of mean temperatures of 1.4 to 5.8 °C. How rapidly can forest vegetation adapt to such predicted large changes, and in which way? We looked for answers in three different disciplines: ecological modelling, palaeoecology and succession theory. We found that changes of forest vegetation after rapid climatic changes can be continuous or abrupt. Rapid or abrupt changes may result within years to decades, among others, from marked drought as a direct effect of climate warming, limiting tree growth in the driest parts of Switzerland within a few years or decades. Indirectly, climate warming affects forest vegetation by forest fires, windstorms and, consequently, insect outbreaks. Questions relevant to forestry arise from these considerations: What is the most suitable combination of tree species for which management should aim in the future, and how do we adequately manage protection forests so that they can resist or adapt to the climatic change?

Ausmass und Auswirkungen der Waldbrände auf die Vegetation der Schweiz im Laufe der Jahrtausende

New palaeoecological investigations (pollen, macrofossil, and charcoal analyses) provide important evidence on the fire history and the long-term fire ecology of different regions of Switzerland. The results from the Swiss plateau, the Northern and Central Alps and Southern Switzerland suggest that fire played a different role for the long-term vegetational development in the different regions. In the Northern Alps and Southern Switzerland anthropogenic fires led to the disappearance of entire forest communities. These fires especially affected the fire-sensitive species Abies alba. On the Swiss Plateau fire frequencies were markedly lower than in the Southern Alps. Nevertheless, fires probably led to a decline in the occurrence of fire-sensitive taxa such as Ulmus, Fraxinus excelsior or Tilia at lower altitudes (Fagus silvatica-Quercus belt). First evidences from the Central Alps suggest that forest fires were naturally more frequent in this continental region and that the vegetation might be better fire-adapted than the original (partly or completely vanished) plant communities of the Swiss Plateau, the Northern Alps and Southern Switzerland.

(Table T3) Vitrinite reflection of samples obtained from ODP Leg 180 sites

Seventy-one samples from Ocean Drilling Program Leg 180 sites were analyzed for vitrinite reflectance and organic type. The objective was to define maximum paleotemperatures across the western Woodlark Basin as a function of depth. The organic matter is of early Pliocene to Holocene age and was recovered from drilled depths of 4.5 to 851.3 meters below seafloor. Organic matter is generally restricted to woody fragments within the sediment, although in a number of fine-grained samples, organic matter is dispersed throughout the sample. Virtually all samples contain vitrinite, part of which may be derived from drifted logs. One sample was found to be barren of organic matter, and two contain only fusinite and semifusinite. Variation of vitrinite reflectance is not systematic with either depth or location, and it appears that formation temperatures have been insufficient to cause an increase in vitrinite reflectance levels. Textural variations within the vitrinite show better correlation with depth. Samples of hypautochthonous peats represent either a terrestrial phase of sedimentation or large peat intraclasts within the section, possibly produced by forest fires in the source areas of the organic matter. The vitrinite and peat-derived samples appear to come from eucalyptus forest settings away from the coastline. Liptinite is not abundant in most of the samples (excluding suberinite associated with woody tissues). Marine liptinite is rare to absent, although many of the samples contain abundant foraminiferal tests. Pyrite is abundant in many of the wood fragments, and some pyritization of woody tissues has taken place.

Haven Hall. Fire. June 1950. Students removing records from burning building

Jordan & Anderson, architect (1863); Spier & Rohns (1898). The old Law Building was renamed Haven Hall in 1933. It became one of the main buildings for LS&A used by Departments of History, Sociology and Journalism. The old Law Library became a study hall and Bureau of Government Library. Extension Division also had offices in Haven Hall.
