Jeffrey-Field and Lab

Lets talk about Water sampling. Last week I collected my sample near the Ormond Boat House on the Halifax River. I used an extension pole to reach out beyond the oyster bed.

The water appeared somewhat clear.
It was quite turbid as I would soon find out.












Back at the Lab we were given instruction on measuring salinity, we used a refractometer.
My sample showed to be 13ppt. Definitely brackish water.

We also learned how to use a turbidimeter. Turbidity is measured in Nephelometric Turbidity Units (NTU). It tells us how cloudy the water is due to suspended solids.



We also learned how to  filter the particles out of our sample using this setup.                                                  

I am looking forward to collecting the last piece

of data in lab this week and comparing it to the groups results. Stay tuned....
