Disque de Secchi

Rosette + CTD

Filet a plancton

Bouteille NISKIN


Slurp gun

Algues des glaces

Fixation des échantillons de phytoplancton:

-Lugol

-Formol

-Glutaraldehyde

Enumeration du phytoplancton:

Préparation des échantillons d’eau pour la mesure de la teneur en pigment:

-filtration sur support GF/C ou GF/F

-extraction dans solvant (90% acétone, méthanol, gradient) au noir plusieurs heures au froid (4C ou -20C)

-mesure de la fluorescence ou de l’absorption des pigments chlorophylliens a une ou plusieurs longueurs d’onde
