Collecting eDNA in coastal waters is an important activity for marine biology, but problematic because of extreme costs associated with it. Manual sampling eDNA from surface water over very shallow coral reefs is complicated and time consuming.

​

​

With the growing demand in the scientific community in mind, not in the least in the battle against COTS, Snorkelbot has a worked-out design, to perform this fully autonomous, over a vast area, at hard to reach locations.

The system has storage for 24 samples. Standard 47mm Filter Membranes/Cartridges are used to pump water through. The system prevents pollution from non-test environments.

After filtering at location, air is pumped through the filter, before the holder is filled with preservation solution, so that sampling can be done at locations, great distances apart, during days or even weeks long missions

​

 

The samples are to be retrieved from the here for upside down turned Snorkelbot, so in quiet shallow water. Each of the 24 metal membrane holders are to be screwed off, and taken closed to the laboratory, where the membranes can be taken out without polluting the samples.

​

​

In a similar way, there is a design for autonomous water sampling, taking full benefit of Snorkelbots sailing over shallow water capability. Taking samples at 24 target locations of 78 cc, or at 12 locations of each 150 cc.

Also here, after a sampling mission, each water container is to be screwed off individually, to be unloaded in laboratory under pollution free condition.
