The Stralsund University of Applied Sciences started very early in promoting the renewable energy use. The historical tendency of the decarbonisation of fuels and other forms of energy and the idea of power to hydrogen (power to gas) including the further use of the gas in the sectors of electricity, traffic, and heat market as well meet each other on the way directed to an energy sustainability. A successful cooperation with the West Pomeranian University of Technology in this area is running since 1994.

Uniwersytet Techniczny w Stralsundzie bardzo wcześnie rozpoczął promocję stosowania odnawialnych źródeł energii. Historyczna tendencja dekarbonizacji paliw i innych postaci energii oraz idea: moc na wodór (moc na gaz) a także dalsze użycie gazu w takich sektorach jak: wytwarzanie energii, transport i rynek ciepła, jak również w innych znanych dziedzinach gospodarki ukierunkowanych na zrównoważoną energię. W tych obszarach, od 1994 roku, istnieje współpraca między Uniwersytetem Technicznym w Stralsundzie a Zachodniopomorskim Uniwersytetem Technologicznym w Szczecinie.

The present study establishes a lithostratigraphic subdivision, a bio- and chemostratigraphy and describes the sedimentology of the Alstatte Bay at the southern margin of the Lower Saxony Basin in northern Germany. The socalled Fischschiefer is developed in the lower part of the section, a 2.1 m thick laminated interval that shows TOC values of up to 2 % and is interpreted as local expression of the global Oceanic Anoxic Event 1a (OAE 1a). The basal part of the Fischschiefer is fairly continuously laminated, whereas its upper part is characterized by an alternation of laminated and non-laminated beds. Stable carbon isotopes ([delta^13]C[carb]) show a characteristic pattern for the Fischschiefer interval that can be correlated with sections from the Tethyan Realm. Immediately above the Fischschiefer, however, the studied section might reveal a diagenetic overprint as indicated by very negative carbon stable isotope values. The remaining part of the section is characterized by a rather monotonous claystone succession, terminated by a greenish layer rich in glauconite overlain by glacial till of Pleistocene age. The fauna is typically Boreal in the lower part of the section, but changes around 2 m above the Fischschiefer towards an assemblage indicating a distinct Tethyan influx. The faunal shift is considered to be due to the maximum flooding of the continuous, long-term sea level rise of the Early Aptian which led also to a supposed shift from a restricted to open bay environment.

The macrofaunal content of an exceptionally fossiliferous Late Albian core section is described from Zippelsforde in the Brandenburg district in eastern Germany. The main faunal horizon includes among others Euhoplites vulgaris, Mortoniceras (Deiradoceras) albense, Neohibolites minimus, Inoceramus cf. anglicus and Actinoceramus sulcatus. This assemblage indicates a Hysteroceras varicosum Zone, Hysteroceras orbignyi Subzone age. That interval is known from the Anglo-Paris as well as from the Lower Saxony Basin in western Germany, but not was previously recorded from the North East German Basin. Therefore, the record fills a palaeogeographical gap between the Albian in the Carpathians and that of Central Europe. The superjacent interval contains Aucellina gryphaeoides, dating it as latest Albian (Mortoniceras (M.) inflatum Zone, late C. auritus Subzone or younger), and thus indicating a significant condensation within the Late Albian.

Sanmartinoceras aff. walshense (ETHERIDGE, 1892) from the Early Cretaceous of California - the first evidence of the ammonite subfamily Aconeceratinae SPATH, 1923 in North America

Sanmartinoceras aff. walshense (ETHERIDGE, 1892), a single large representative of the Aconeceratinae SPATH, 1923 from California is believed to be a macroconch. It shows close relations to Sanmartinoceras africanum KENNEDY & KLINGER, 1979 and Sanmartinoceras walshense, however the described combination of features is unique. Until the variability of this ammonite is established we assign this specimen to Sanmartinoceras aff. walshense. It is probably Late Aptian in age and represents the first evidence of the Aconeceratinae in North America

Przedstawiono nowy sposób inicjowania silnych wstrząsów sejsmicznych robotami strzałowymi urabiajaco-odprężającymi z wykorzystaniem skoncentrowanego ładunku materiałów wybuchowych (MW) umieszczonego w wielkośrednicowym otworze strzałowym. Dokonano wstępnej oceny skuteczności zaproponowanej metody w warunkach geologiczno-górniczych oddziału G-6 Kopalni RUDNA oraz oddziału G-6 Kopalni LUBIN.

There is presented a new method initiating strong seismic tremors by means of blastings with use of concentrated MW charge placed in a blast-hole of great diameter. The effectiveness of the proposed method was temporarily evaluated in the geological mining coditions of G-6 flats of the Mines RUDNA and LUBIN.

Conodont fauna recovered from pelagic nodular limestone sequence exposed near Santa Olaja de la Varga precisely dates the upper part of the Alba Formation in the Esla area of the Cantabrian Mountains. In terms of goniatite stratigraphy, the formation ranges into the early Namurian E2 interval which has been identified by the occurrence of the conodont Gnathodus bollandensis. The investigated conodont fauna includes exclusively deep-water forms and is dominated by species of Gnathodus and Lochriea. The former genus is represented primarily by the bilineatus lineage, in which a new species Gnathodus cantabricus sp. nov. has been recognized and is described herein. Representatives of the another gnathodontid girtyi lineage,generally present in the late Visean/early Namurian deep-water faunas, are extremely rare. The vertical succession of Lohriea species is closely comparable to those recognized in Northern England, Poland andUkraine. The Visean/Namurian boundary is thus placed at the first occurrence of Lochriea cruciformis, 4.7 m below the top of the Alba Formation.
