13:00-13:30 | Dr Phil Hosegood: Sharks in the surf zone: how internal waves create predator hotspots
Phil will show how Silvertip shark aggregations over tropical seamounts are explained by the schooling of fish that are a response to internal waves that break over the drop off surrounding the seamount summit. The waves are predictable in time and space due to the tidal currents that generate them; by understanding the ocean dynamics that drive such turbulent events in biological hotspots, we are better able to develop appropriate conservation strategies by more accurately predicting where, when and why top predators aggregate.
13:30-14:00 | Dr Jenny Gales: Using ocean exploration to understand Antarctic ice sheet change
The rate that Antarctica is losing ice is increasing with global effects to sea level rise, ocean and atmospheric circulation. Understanding how ice sheets have changed over decades to millions of years, in response to past changes in climate, is crucial in understanding how ice sheets will change in the future. This will allow us to estimate future global sea level rise. This talk will focus on cutting-edge tools used in ocean exploration to study how Antarctic ice sheets are changing and have changed in the past. These tools include a range of autonomous and marine robotics, deep sea drilling, smart sensors and ways of mapping the seafloor and beneath.
14:00-14:30 | Professor Richard Thompson: Marine litter: are there solutions to this global environmental problem?
Plastic debris is widely distributed at the sea surface, on the sea bed and on shorelines. Nearly 700 species are known to encounter marine litter, with many reports of physical harm resulting from entanglement in and ingestion of plastic. At the same time it is very clear that plastic items bring many societal benefits. Can these benefits be achieved without emissions of waste to the environment? Progress requires systemic changes in the way we produce, use and dispose of plastic. As well as reducing usage, a key solution to two major environmental problems, our non-sustainable use of fossil carbon (to produce plastics) and the accumulation waste, lies in recycling end-of-life plastics into new products.
14:30-15:00 | Dr Mark Davidson: Extreme storm impacts on the coast
As our climate warms and sea levels rise, increasing pressure is being placed on the coastal environment in terms of the risks of coastal erosion, flooding and loss of valuable infrastructure. This presentation will focus on the impact of the extreme storm waves on the coast with a specific case study focused on the UK South West coastline. Examples of how storms can impact the coastal environment will be given and the different coastal processes that augment this change will be explored.
