Tvärminne - UHEL
Tvärminne Zoological Station (TZS) is a marine station located at the entrance to the Gulf of Finland in the Baltic Sea. Despite its name of historical origin, it serves as a centre for a large variety of high quality biological and ecological research, carries out environmental monitoring, and offers facilities for field courses, symposia and seminars, also in non-biological disciplines.
The station was established in 1902 and provides good background data for studying long-term environmental change. Long-term monitoring data from the TZS area is available on temperature, salinity, nutrients, chlorophyll, zooplankton and benthic macrofauna, and one of the weather stations of the FMI is located at TZS.
TZS has two larger boats, RV Augusta (18.5 meters long) and
RV J.A. Palmén (10.3 meters long), and several smaller boats for coastal sampling. There are diving facilities and standard sampling equipment such as water samplers, plankton nets, sediment corers and grabs, dredges and trawls, and handheld probes (CTD, oxygen).
The station is well equipped for conducting large-scale field experiments as well as indoor experimental facilities with flow-through seawater, and a laboratory for seawater and sediment analyses. TZS has a class C isotope laboratory and is certified as a University of Helsinki facility for experiments with animals (fish).
The station is operational all year around and we welcome visiting scientists, Finnish as well as foreign, to conduct their research at the TZS. We offer accommodation for more than 80 persons at a time. Please see details of travel and lodging, as well as contact information, from TZS homepages.
