Beneath the Surface…

Following on from my last field note, I returned to the water samples collected from Lough Neagh in April and July to examine them more closely under the microscope.

During my first visit in April, the water at the shoreline was clear, with little visible activity. The microscopic images taken from these samples became my first record of what was happening beneath the surface.

When I returned in July, the change at the shoreline was dramatic. Thick dark green algal matter had accumulated along the water's edge, so I was particularly interested to see how these later samples might compare.

Surprisingly, under magnification the July samples were still relatively clear, with little movement or obvious microscopic activity. The dense green material gathered along the shoreline was also not the blue-green algae (cyanobacteria) that I had been hoping to observe.

Although the microscopic images are perhaps less dramatic than I anticipated, this is all part of the research process. What is visible at the shoreline doesn't necessarily tell the whole story of what is happening within the water.

For now, I will continue to collect and examine samples as conditions at Lough Neagh change, gradually building a visual record of what I find both above and below the surface.
