BOTTLES

rosette:

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

TEMPERATURE

thermometer:

measures temperature

SALINIT

Y hydrometer: measures density convert to salinity

SALINIT

Y refractometer: measures how much light

bends converts to salinity

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
