Webinar abstract:
The ocean takes up about 25% of the carbon we add to the atmosphere, slowing climate change, and reducing its intensity. Part of this process is through the biological carbon pump (BCP) which cycles and recycles carbon from the surface to the deep ocean. Fish, their predators, prey and poo are all a part of this cycle. Human activities at sea, such as fishing may therefore affect or influence the process, through removals of fish, or seabed impacts. Despite this, we have little knowledge, yet much debate, about how much the fish themselves, and the fishing activity may contribute to the BCP. This could be either positive or negative, and therefore could reduce or increase the protection we can gain from the effects of climate change.
