In these years six teams attempted the row. eDNA data was collected each year, manually in 2022 and automated in 2023-2024, with a 10-minute cycle at 8 AM and 8 PM BST daily. The full raw and processed data collected from 2022-2024 is part of an active research project at the University of Portsmouth and will be made available after publication. If you would like access to the full database you can get in contact with Professor Fay Couceiro at fay.couceiro@port.ac.uk. GB Row Challenge was founded by Will de Laszlo and Jim Bastin to highlight the environmental impact of humans on our planet, but also - by creating awareness - to change human behaviour.

The filter allowed us to collect microplastics bigger than 0.04mm in size - at the lower end of this size range the microplastics would be microscopic (invisible to the naked eye). The system was programmed to run for three hours (12 - 3 pm) each day during the race. We had to limit the time that the pumps were running since the noise of the pump interfered with the sound recording devices elsewhere on the boat. The filters were changed by the crews daily, protectively encased and then stored until the boats’ returned. The samples were then delivered to the University of Portsmouth’s School of Civil Engineering and Surveying for analysis. To start with, we targeted specific time points when the crews reported sightings of particular things (e.g. boats or dolphins). Once these events were also recognised in the sound recording, a spectrograph of the sound was made to show the sound visually. This allowed us to build familiarity with the data, and identify some archetype examples of different marine sounds. We found that using the high frequency capabilities of the hydrophone (10-192 kHz) allows us to cancel out the noise of the rowing itself and identify a number of distinctive marine sounds.Not detecting a species’ DNA in our sample does not mean that the species is not there, just that it’s DNA was not captured in the 1 Litre of water sampled from that area. With repeated samples taken over the following years we will build up a more comprehensive picture of the species present in each area, yielding one of the most detailed baselines of British coastal biodiversity. It is important to monitor how these species maps change over time. Southern species moving north could indicate effects of climate change and warming seas, while pollution events, overfishing and the arrival of invasive species can also negatively impact biodiversity. Meanwhile, there are many brilliant conservation projects underway that can increase biodiversity in a relatively short period of time. Mapping the biodiversity of UK seas annually this way is a great way to monitor these effects on the species beneath of seas.
