In spring 2013/2014, GLEONites from the Northern and Southern Hemispheres undertook a challenging spring sampling campaign called Spring Blitz. This Global Lake Ecological Observatory Network (GLEON) project was a coordinated effort from researchers around the world to study and link changes in water column stability to plankton diversity during the onset of stratification. Spring Blitz makes use of the GLEON network of sensors in lakes with differing stratification regimes and was the focus of several graduate student PhD theses at Lake Erken, Mt Bold Reservoir and Milltown.

The intensive sampling campaign collected biological community composition data of microbial plankton, phytoplankton and zooplankton in the participating lakes (Table 1). Standardized operating procedures were used to sample each lake every four days at different depths during the onset of stratification in spring. In addition to species information, data were collected on nutrient availability and other water quality parameters to back up the sensor data.

In 2016, the Spring Blitz working group members have set two important deadlines. The first is to upload abiotic datasets (high resolution buoy data, and physical, chemical and nutrient data) and complete Lake Analyzer on all Spring Blitz sites by mid-March. The second is a little more challenging and requires all the biotic datasets to be counted, finalized and uploaded by the end of June 2016, just before the GLEON 18 & NETLAKE Meeting in Lunz & Gaming, Austria.
