Colectare APA de la adancimi diferite > Van Dorn water sampling bottles
Definition = The idea behind these samplers is to allow water to be collected at a known depth. The Van Dorn bottles are used for sampling at various depths and the Kemmerer water sampler is used for surface water samples.

Secchi disk [masurarea transparentei apei]
Definitie: https://en.wikipedia.org/wiki/Secchi_disk

METODA (propusa de CT):
1) stabilirea unui set de PUNCTE (din lac: coordonate GPS - deja stabilite in Google Earth)
2) stabilirea unui program (momente in timp: de exemplu, saptamanal / cand se inregistreaza si alti parametri ex: temperatura, pH etc)
3) realizarea unor GRAFICE
4) trasarea unor limite (min, max, medie, critice / alarma, etc) + interpretari asociate

CUM (confectionare):
1) disc cu diametru de 20 cm (cu 2 zone albe si 2 negre). Preferabil pe un disc metalic, de care se leaga o sfoara ...
2) sfoara are semne la 50cm (ex: noduri / semne cu marker-ul)
3) pe partea cu umbra a ambarcatiunii, se fac 2 masuratori: la coborare si apoi la urcare (se noteaza media)
4) se recomanda a se utiliza cam acelasi interval orar (intre 10:00 si 14:00)

INTERPRETARI:
1) http://www.secchidipin.org/index.php/monitoring-methods/the-secchi-disk/evaluating-eutrophication-by-secchi-depth/
