Summary
[edit]DescriptionWater sampling (4946333692).jpg |
This sensing device called the SeaBird Conductivity, Temperature Depth (CTD)measures the conductivity of water to determine salinity, temperature and depth. Data is sent to a computer lab on the ship and recorded as the device is lowered through water column. Lids on the grey bottles are closed remotely to capture water samples from specific depth for further testing.
