![]() An interlaboratory study of TEX 86 and BIT analysis of sediments, extracts, and standard mixtures. Because if one had to name a single unexplored field in marine research, then that would certainly be microbiology!’ Furthermore, our research also teaches us a lot about the current microbial life in the ocean. If we also subsequently try to recognise and understand the shortcomings of all those different substances, then will keep getting closer to recognising and understanding the climate of the past. Kaiser graduated from the Loma Linda University School of Medicine in 2006. Our work therefore revolves around finding many different points of reference. In my elective practice, I perform hip replacements, partial and total knee replacements, and complex revision procedures for deformities, infections, and trauma. However, when we examine a collection of, say, five imperfect substances and each of the five tells the same story, then we do have a valuable indication. Since joining The Permanente Medical Group in 2008, my clinical practice has been focused on the treatment of various hip and knee problems and general orthopedic trauma. All the substances we investigate have their own shortcomings. No metaphorical thermometer exists somewhere that directly reveals what the temperature in a certain period was. Dr Johannes Zechner Freie Universitt Berlin. ‘Ultimately, there is no such thing as the “ideal proxy” for the climate of the past. PDF Wolfram Kaiser, Stefan Krankenhagen and Kerstin Poehls, Exhibiting Europe in Museums. Sometimes we think we have found a fantastic relationship between a fatty acid and the temperature while working in the laboratory, only to discover in the field that the reality in nature proves to be somewhat more complex.’ Collecting imperfect techniques They are affiliated with medical facilities such as Essentia Health St. For example, we culture bacteria in the laboratory at different temperatures and then examine the influence of those temperatures on the fatty acids these organisms produce. Stefan Kaiser, MD is an occupational medicine specialist in Duluth, MN. ‘We mainly look at the different chemical compounds that occur in bacteria and other microorganisms. We do not literally look at the temperature but instead at “proxies”: substances that indirectly tell us something about the temperature or chemical composition of the atmosphere or the oceans.’ Bacterial culture We are working on techniques that will allow us to read that archive. ‘Ocean floors contain a kilometres-thick archive that, amongst other things, is full of information about the temperature during various periods in the past as well as the composition of the water and air above the ocean floor. Stefan Kucera advises national and international investors, funds, real estate managers, loan servicers, familiy offices, and insurance. ![]() Marine microbiologist Stefan Schouten searches for chemical compounds that can divulge details about the climate in earlier times.
