Description 
Summary

PEX was an intensive multi-ship exercise designed to elucidate and quantify small-scale structures in the Baltic Sea. Scientific objectives included investigating the role of physical, chemical and biological interactions in determining ecological stability, as well as providing a statistical basis for assessing the significance of environmental data collected for monitoring purposes. PEX was a regimented exercise with research ships working stations along one line of an 11x6 grid. Two sizes of grids were employed, the larger one being called the eddy grid. Within this grid, 4 ships anchored and worked hourly stations during the period of the expedition. In addition 11 current meter moorings were deployed at strategic places within the eddy grid. The Swedish data were collected by R/V Argos, R/V Svanic, Coast Guard vessel Tv171 and a Coast Guard airplane. The data has been quality controlled.
