Recap SYD field trip #9

By Blue Carbon Lab | Citizen Science, Fieldwork, HSBC | Comments are Closed | 19 March, 2019 | 0

Date: March 19, 2019

Participants: HSBC, Green Collar, Cairns Airport

Site: Towra Point Nature Reserve, Sydney

Research: Effects of Nutrient run-off on Blue Carbon stocks and fluxes

Our Nutrient experiment comes to an end!

The experiment, which looked at the effects of nutrient run-off on Blue Carbon stocks and fluxes, was set by citizen scientists in June 2018, and had been monitored by subsequent teams in August, September, November 2018. This March field trip was the final one, with the 30 experimental plots sampled one last time (ie. to capture the effects of the warm summer temperatures on the plots).

After the morning talks at HSBC’s Barangaroo office, participants traveled to the field site, where different wetland sampling protocols were demonstrated. Soil cores, microbe samples, and plant surveys on each of the plots were completed in just a couple minutes, with most of the time and efforts spent trying to recover all the tea bags (including those lost by previous participants).

Tea bags were extremely hard to find, as in the last 9 months, flags were moved, labels erased, roots had grown and much of the soil had been mixed. Some teams were unlucky and had to search blindly  for their tea bags, as lots of ground water had inundated their plots! (ie. search was all relegated to the touch and feel of the bag in the mud).

Despite the many issues, the search was quite successful! From the 240 tea bags deployed 9 months ago, we successfully recovered 219. This team alone was in charge of recovering 58 tea bags.

Many thanks to all the participants that joined the #BlueCarbonArmy and participated in the nutrient research! All the samples are now being processed and we will soon be able to share all the results and findings form this project.
