Service

In Situ Observation and Sampling

The In Situ Observation and Sampling Service determines water and benthic marine quality. Its determination comprises sampling followed by: 1) identification and analysis of different parameters (water clarity, dissolved oxygen, pH, alkalinity, pigments, organic matter, volatile organic compounds and lipids, microbial enzymatic activity, primary production, bacterial production); 2) census and identification of biological samples; 3) design and implementation of experimental approaches; 4) analysis of underwater images.
