WATER
SAMPLI
NG
BOTTLES
Niskin and Nansen bottles:
collects water sample from depth for further analysis

BOTTLES
rosette:
many sampling bottles with CTD in middle allows collection of watersamples at many depths

TEMPERATURE
thermometer:
measures temperature

SALINIT
Y refractometer: measures how much light
bends converts to salinity

SALINIT
Y
CTD - conductivity, temperature, depth:
measures electrical conductivity converts to salinity

TURBIDIT
Y
secchi disc:
measures cloudiness of the water

DISSOLV
ED
OXYGEN
dissolved oxygen meter:
• measures oxygen levels in the water• organisms need oxygen to “breathe”

SONAR
• uses sound waves to search forobjects in the ocean
