Net towing by moonlight
The most abundant forms of life at Station Aloha are those that cannot be seen by the naked eye. Bacteria, viruses, and most phytoplankton and zooplankton can only be seen using a microscope. In order to view the plankton in the water you can use a funnel shaped net called a plankton net which is dragged or "towed" through the water. The net allows water and very small particles flow through but collects plankton that are bigger than the mesh size. The plankton are concentrated in a bottle attached to the bottom of the net. The contents of the bottle (lots of phyto and zoo plankton!) can then be viewed under a microscope. We saw pennate and centric diatoms, radiolaria, copepods and much more.

It is so good that you have the SKATE BUS that is why your visitors can save their time and money. The price is not too small but still...for good service people should pay more money like writing services help people with different essays.
