    Notes: Abstract A series of 72 measurements of the acetaldehyde (CH3CHO) mixing ratio were made in the lower troposphere during TROPOZ II. These measurements are the first ever made of the background level of this trace gas in the free troposphere. The data show a vertical decrease of the CH3CHO mixing ratio with increasing altitude and indicate higher CH3CHO concentrations in the Northern Hemisphere — in general agreement with a model-derived average CH3CHO distribution. Deviations of the observed CH3CHO mixing ratios from the modelled mean distribution are correlated with similar deviations in the corresponding HCHO mixing ratios.

    Topics: Chemistry and Pharmacology , Geosciences
    Notes: Abstract A series of 149 measurements of the HCHO mixing ratio were made between 0 and 10 km altitude and 70° N to 60° S latitude during TROPOZ II. The data show a vertical decrease of the HCHO mixing ratio with altitude at all latitudes and a broad latitudinal maximum in the HCHO mixing ratio between 30° N and 30° S at all altitudes. The measured mixing ratios of HCHO are considerably higher than those expected from CH4 oxidation alone, but agree broadly with the average latitude by altitude distribution of HCHO derived by a 2D model including emissions of C1–C7 hydrocarbons. A number of the regional scale deviations of the measured HCHO distribution from the average modelled one can be explained in terms of the local wind field.

    Description: Im oberen Korallenoolith (Oxford-Kimmeridge) von Oker entwickelten sich kleine lagunäre Riffe, deren Gerüst aus Exogyren, Serpeln und großen einzelnen Korallenstöcken gebildet wurde. Die umgebende Fazies besteht aus stabilen Weichböden mit reicher Molluskenfauna (Nerineen, Lamellibranchiata). Gerüstbildende Algen werden nicht beobachtet. Dasycladaceen sind selten. In Zwickeln, Kleinhöhlen und leeren Exogyren-Schalen siedelte sich eine diverse Poriferen-Fauna an, die von tetractinelliden Demospongiae dominiert wird. Durch Umwandlung von Teilen des Schwammgewebes in Automikrit kam es zu einer in situ Erhaltung vieler Porifera-Skelette (bakterielle Ammonifikation). Neben diesen autigenen Mikritbildungen spielen weitere stromatolithische und thrombolithische Mikrobialithe bei der Stabilisierung der lagunären Patchreefs eine erhebliche Rolle.
    Description: In the uppermost facies of the OxfordianiKimmeridgian "Korallenoolith" of Oker small lagoonal patchreefs are present. They are constructed of exogyrid oysters, serpulids, and large single scleractinians. Framebuilding algae are absend. The surrounding sediments were stable soft bottoms with large numbers of nerineid gastropods and semi-infaunal bivales. Dasycladacean algae are rarely present. Within small caves, empty conches of exogyrids, and inter biogene spaces settled a large number of cryptic sponges (mainly tetractinellid demosponges). Caused by bacterial ammonification part of the sponge soft tissues were altered in automicrite. Therefore the sponge skeletons exhibit more or less their entire shapes. Beside this type of automicrite stromatolitic and and thrombolitic microbialites play an important role in stabilizing the patchreef frame.
