The Aranda cruise investigated the Baltic Sea, and the Kattegat and Skagerrak on July 2017, 10th – 17th. 18 stations were investigated for JERICO-NEXT. The main objectives of the cruise were to investigate the vertical and horizontal distribution of cyanobacteria and zooplankton and characterize phytoplankton.

Hourly measurements using the Huvudskör E. buoy. Several abiotic and bio-optical parameters are collected. For phytoplankton, chlorophyll and phycocyanin fluorescence are the most relevant parameters.

SHARK ("Svenskt HavsARKiv" / "Swedish Ocean Archive") is the national marine biological monitoring database of Sweden, holding monitoring data on phytoplankton, zooplankton, bacterioplankton, phytobenthos, zoobenthos, seals, primary production, sedimentation and chlorophyll measurements.

<para>Zoobenthos have been regionally monitored in Sweden since 1972. The monitoring is financed by the Swedish county administration boards, Swedish municipalities, Swedish coalitions of water conservation and Swedish companies. Recipient control data financed by companies are also included.</para>
