The weather was not particularly inviting to start with |
Today the McLane Time Series Sediment Trap was deployed, to
a depth of 450 m. This trap, with a honeycombed structure to slow the settling
of material, will allow any jellyfish particulate matter to be quantified using
isotope signature analysis, and also determine overall particle flux. The trap
consists of a funnel to catch the particulates, as well as a series of sample
bottles to contain the material, which will be changed every 14 days. After a
year, the attached KumQuat acoustic release transducer will be triggered which
releases the weighted trap, which then floats to the surface to be collected.
