Hello everyone,
The sampling techniques I used in the field were a bit different from the ones listed in the tutorial. The areas I chose to study were located in lentic and lotic ecosystems. The benthic invertebrates and periphyton were mainly collected during the fall. The water samples were collected on a bi-weekly basis (if accessible) for water quality analysis.
Study components:
Water and tissue chemistry: to analyze selenium concentrations in samples of surface water, invertebrates and periphyton.
Field Sampling:
Sampling approach – systematic sampling
Surface water – all the surface water samples that were collected from the stream were based on BC Field Manual. The samples collected were submitted to a CALA certified lab in the lower mainland.
Physical habitat assessment – CABIN field protocols.
Benthic invertebrate samples – kicknet (stream) and sediment grab sampler (wetland). After collecting the benthos, they were sieved from debris, then rinsed, patted dry and put into a freezer. The samples were submitted to a lab for analysis.
Periphyton – collected from hard substrates using a clean scraper (stream), glove hand or 400-µm dip net. After collecting the periphyton, the sample was patted dry, placed in sample packages and put into a freezer.
Cheers,
CQ
