✦ Synopsis

Evaluatio~ o/the living organi~ materia~ in marine waters by ~easuring adenosine triphosphate

Quantitative determination of living organic matter (micro-organisms) in the ocean were made using the adenosine triphosphate (ATP) assay. STgEm, ER and TOTT]~g'S (i952) method was used. A simple apparatus recorded the photons emitted from the very beginning of the photochemical reaction; the assay is specific for ATP but enzymes present in Photynus ~yralis suspension may create errors. The sea-water ATP values in l~arseflles Bay range between 2.10 -~ and 80A0 -~ mg per m ~. An offshore profile of the Mediterranean Sea, near Toulon, gives values around 10 -a mg/m a. Protein assays have been made on the same samples. The differences existing between certain values in the series are attributed to inert particles.
