With climate change causing sea temperatures to rise, bathing may become less safe. Bacteria such as Vibrio, which can infect humans, thrive in these warmer waters, as do harmful algal blooms.Our study looks at the impact of climate change on bacterial communities and algal blooms. How can we better understand this relationship, and from our research, develop strategies to protect human health?A team from Deltares along with researchers from the Universities of Exeter and Bangor are getting up close to Vibrio and faecal bacteria (in the hope that we won’t have to).
