Weather: Gale of 45 kmph,
cloudy.
It's my second visit to Migneint bog, Wales. Like other field
trips, I was with my class mates and teachers. This time we were there to learn
new techniques of experiments and collect various samples. This included setting
up of field experiments, water sample collection and gaseous fluxes measurement.
Demonstration to fix gas chambers |
Our day started with two hour drive from the University with a
team of 10 people. After reaching to the Migneint, we had an opportunity to
visit University experiment site, which is running in the Migneint bog with the
collaboration of Centre for Ecology and Hydrology, and Natural Environment
Research Council. The purpose of the experiment
is to monitor effects of air pollution on the stability of carbon and nitrogen
stored in the soil. The study is targeted to protect sensitive upland soil and
freshwater ecosystems against the effect of climate change.
The study site was divided into three types of plots – plot
with red boundaries indicates vegetation with acidic soil, plot with blue
boundaries indicates vegetation with alkaline soil and plot with white boundaries
indicates vegetation with neutral soil.
Gas chambers |
After reaching to the study site, Dr. Tim demonstrated us a procedure
of water sample collection. Later he taught us a gas extraction method with the
help of dark and transparent chambers by using syringe. Simultaneously, we also
got a chance to collect gaseous content from the study site. I feel, it was a
good opportunity for us to visit the project site again and understand various techniques
from experts. After learning session, we assisted Dr. Tim to sprinkle acidic,
alkaline and neutral solutions on the site.
The idea was to sprinkle solution into various plots by taking
consideration of color boundaries. Reason behind whole procedure was to check
the influence of chemicals on bog and utilize same knowledge for the prediction
of acidic rain effect on bogs. We also collected two buckets of peat to analyse
it in the laboratory.
Ditch drainage |
After having lunch we headed
towards another site of same bog and sprinkled solutions there by following
same procedures.Then after, some of us decided to go further with Dr. Tim to
collect samples and data from another site.
That site was far from the second site but we managed to reach there
within 20 minutes. Dr. Tim quickly collected water samples and data from the
installed machine to collect DOC value of stream water. It is really important to have data of DOC
from this bog as this is a source of stream water to Wales. Though whole trip went well, we were challenged by an extreme
weather throughout the day. First time I experienced and realized how much
efforts a wetland scientist has to provide from fields to laboratory for the conservation
of wetlands.
