The SatBaltic buoy returned to its place near the mouth of the Vistula River, Gdansk Bay on 7th of June 2017. Until the end of the summer it will stream data regarding water properties. It will provide real-time measurements about physical parameters (temperature and salinity), optical properties (the light absorption and attenuation coefficients) and  meteorological situation (air temperature, atmospheric pressure, wind speed). Thanks to the AIS (Automatic Identification System) you may track it on the website:https://www.marinetraffic.com/pl/ais/home/shipid:850631/zoom:14 Zdjęcia: Marta Konik
