The pastand future changes of the sea’s coastline described in the two closing papers will, perhaps, remind everybody that nothing, not even the sea, is forever. I would like to say that working on the volume as guest editor has given me lots of satisfaction and unexpected pleasure. In this capacity, it is also a great pleasure for me to thank the many individual

contributors for their involvement and assistance with the issuing of this volume. First and foremost, I would like to express my sincere gratitude to all the authors and anonymous reviewers. Their commitment to convey science to our readers and to the maintenance of scientific quality have been, of course, the essential driving force behind all the papers included in Bleomycin ic50 this volume. The technical editor of ‘Oceanologia’, Sabina Szczykowska MSc, deserves special thanks, as she had to deal with the authors, reviewers, coordinate the linguistic correction procedure, the printing office, not to mention the guest editor. Nobody could have done the job better. The people at the BALTEX secretariat, especially Dr Marcus Reckermann, collected the manuscripts from the authors and stored them safely until the editorial office took over, and so were an important link between the authors and the journal.

I strongly believe that both the content and format of this volume will satisfy our readers and will encourage them to look forward to the see more next 7th study conference on BALTEX, which will be held on the Swedish island of Öland in May/June, 2013. “
“Within the recently performed Baltic Sea Experiment (BALTEX)

Assessment of Climate Change for the Baltic Sea Basin (BACC 2008; see also http://www.baltex-research.eu/BACC) it was concluded that ‘identified trends in temperature and related variables (during the past 100 years) are consistent with regional climate change scenarios prepared with climate models’. BACC enjoyed active contributions by more than 80 scientists, and the BACC material was used by the Helsinki Commission (HELCOM) for its own climate assessment report of the Baltic Sea (http://www.helcom.fi). Regional climate model (RCM) results suggest that global warming may cause increased water temperatures of the Baltic Sea, reduced sea ice cover, possibly increased winter mean wind speeds causing increased Ribose-5-phosphate isomerase vertical mixing, and possibly increased river runoff causing reduced salinity (BACC 2008). The projected hydrographic changes could therefore have significant impacts on the Baltic Sea ecosystem, e.g. species distributions, growth and reproduction of organisms including zooplankton, benthos and fish (e.g. MacKenzie et al. 2007). Unfortunately, the details have not been investigated thoroughly and, according to BACC, the complex response of the ecosystem is unknown. First results from physical-biogeochemical modelling applying the so-called delta approach (e.g. Hay et al.
