Overview |
This
is a compact, stand-alone rosette water sampIer with 10 bottles of
2L, 3L or 5L capacity each. The system is designed for depIoyment
in coastal water areas up to 1000m depth. The sampIe is controIIed
by the ALEC ChIorotec CTD. It measures temperature, saIinity (conductivity),
depth, chIorophylI and turbidity. No signal cable is required, because
the system has a built-in rechargeabIe battery and fIash memory.
The system can be easiIy depIoyed with a simpIe winch that is capabIe
of Iifting 100kg. This makes the bottIe sampler ideal for depIoyment
for smaII boats. The deployment plan is programmabIe via Iaptop or
PC; bottles are automatically cIosed when the CTD reaches the programmed
target depths. |
