A post for those who love dolphins) Enjoy! My recent volunteering for dolphin monitoring expedition brought me to a marvellous world with glorious sea scenery, interesting meetings and challenging tasks.
Green Balkans declared November the month of dolphins. Every month they devote to certain species and educate about them with creative activities, quizzes and games. This year the expedition devoted to the counting of dolphins overlapped with the programme but it’s a regular scientific project carried out in Bulgaria twice a year since 2017.
Dolphin monitoring in the Black sea is a vessel survey with the application of the internationally used method distance sampling. The trained team observe transects with binoculars with an in-built compass and record information about spotted species: the type and number of dolphins, coordinates, behaviour and weather conditions. What’s great about such research is that anyone can participate in it as a volunteer.
I learned about such an original project during my conservation holidays in Pomorie. The head of the expedition ecologist Dimitar Popov was sharing exciting details of the previous dolphin studies during his talk about cetaceans in the Black sea. About 200 000 dolphins of three species live in the Black sea.
The scientist also presented a book (in Bulgarian) about their expeditions written together with his colleague and wife Gallinula Meshkova and volunteer Teodora Ilieva.
‘Ideally, all the countries that border the Black Sea should conduct such research simultaneously, – said Dimitar Popov. – But in reality, it’s almost impossible to organize. There’re six international partners: Bulgaria, Georgia, Romania, Russia, Turkey and Ukraine, and everyone has different financial and political situations. Last year was probably the most productive in term of collaboration. We did an international aerial survey of dolphins all together’.
Our November expedition lasted for one week during which 43 dolphin observations were recorded (in total 200 for 2020). But I volunteered only for two days due to sea-sickness. The first day was devoted to training in Balchick on yacht Kaliakra. We learned how to use the equipment and record data.
Except for me, there were two more volunteers. Teodora Ilieva (in the image below in the right), a meteorology expert in hailstone from Montana. She began participating in the expedition from the very beginning. Petya, a teacher from Varna, eagerly supports volunteer projects of great social value that allow learning new things (cleaning beaches from stranded dolphins and supporting participants of mounting marathons).
Having spent the night on the yacht, we met the sunrise in the open sea. The working day began at 7 am and finished at 4.30 pm. Each of us was on duty with binoculars for 30 minutes. Except for dolphins we recorded birds. It was quite a tiring and exciting task at the same time.
It was very beautiful around and nature changed every minute. On the other hand, it was quite scary. The qualm caused by sea-sickness was making it difficult to move around the deck and concentrate on the task. This gamut of emotions allowed me to feel the mood of that mighty place that embodies the three natural elements: water, air and space. That world doesn’t belong to us but it never stops attracting us and capturing the imagination with its eternal magic that can be inspirational or threatening depending on our fears.
Studies on dolphins in the Black sea are very scarce. That’s why scientists welcome any public support in observation and recording of encounters with dolphins, both alive and dead. The special application Black Sea Watch allows everyone to become a social scientist and report any information about dolphins with a mobile phone. The application is a great database and learning tool at the same time that connects nature lovers and scientists and enables them to exchange information.
It’s really fascinating to develop environmental literacy reporting observations and learning from them!
