Jumping in where we left off, I’ll get back to the rundown of the week and also explain how the module will be assessed this year!
Day Four – April 4th
The agenda for the fourth day consisted of a trawling sample in The Firth of Clyde. We went out in two groups to sample from both a rocky- and muddy-bottomed area of the Firth, using a trawling net and a grab. Many crustaceans, brittle stars and starfish, as well as a few fish were caught and later released after identification. Also sampled were the zooplankton, who form a vital part of the marine food chain.
Day Five – April 5th
Back at Kames Bay, we surveyed the plastics present on the beach. Many of it sits near the top of the beach, and once you start looking you realise it’s everywhere, and could have been washed up from anywhere – we saw a few shotgun shell casings. If you take a closer look, you can see vast amounts of nurdles: small plastic beads that make up the raw material of many many products. These, along with regular plastic items, have become a huge problem in aquatic ecosystems, and this surveying was a real hands-on eye opener to the dangers of unsustainable living.
Day Six – April 6th
Again, the weather challenged us with wind and rain, but we cycled anyway. Turning from sun to storm and back again every twenty minutes, we surveyed the shores from the coastal road, tallying the numbers of birds and aquatic mammals for ten minutes at each location. After a lap of the island, my group stopped off in town for some food and to get some typically touristy photos of ourselves with the Crocodile Rock, before an evening in the pub!
Day Seven – April 7th
After the usual delicious early breakfast, the journey home began. Thankfully, there were far fewer mishaps than on the journey up. Personally, I really enjoyed the week. It was a lot of work, with sampling in the day and ID’ing into the evenings, but it was worthwhile. The experience was one I will never forget.
What I didn’t mention above, is that on the final full day – after the surveying but before the pub – we had a mock ID test. This consisted of many specimens being presented to us and being tested on identifying it outright or being asked to match two species’ names to each individual. The actual ID test this year will require the identification of species from memory and others using a key. Alongside this, there will be an hour long data retrieval test, that will assess the “keeping of records of the extensive practical and field-based investigations, and the associated data collection and analyses.”
