Ziel der Reise / Objectives of Cruise:

1) BLUEPRINT: The project aims at establishing indicators for the environmental status of the Baltic Sea, based on the biodiversity and genetic functional profiles of microbes in seawater samples. During the cruise POS488 seawater samples for microbial community, DNA and RNA analyses were taken with CTD from (mainly coastal) stations. In combination with the regular CTD sampling, in situ fixed water samples were taken using the Automatic Fixation - Injection Sampler (AFIS) to generate functional microbial fingerprints from anthropogenically impacted regions. Additional to the regular sampling campaign, incubation experiments were carried out at 6 different stations (cities, estuaries, pristine and agricultural areas) to analyse the reaction of microorganisms to stress as an indicator for organic pollutants. 2) MIKROMIK: The coastal zones of the Baltic Sea are strongly influenced by anthropogenic activities, which suggests, among other impacts, an inflow of microplastics via rivers, harbors and sewage treatment plants. Distinct data on the abundance, distribution and polymer composition are missing for the Baltic Sea. Further, it is yet unclear whether microplastics serve as vector for microorganisms, including pathogenic bacteria. Therefore, we sampled surface water (Manta net) and sediment (Van Veen and box grab). Back in the laboratory, we will analyze the samples regarding abundance, composition and spatial distribution of microplast. 3) Seawater and sediment samples were taken from all stations to generate metadata (pollutants, nutrients etc) for our datasets.
