Marine Alliance for Science and Technology for Scotland

Events

Every Wednesday at 13:00 UK time, plus a live Q&A with our speaker

MASTS is delighted to announce that we have collaborated with EMBRC: European Marine Biological Resource Centre to provide you a collective webinar series! These exclusive webinars include a live Q&A with the speaker and will all be recorded. 
 
Last spring and summer, MASTS ran a series of weekly and publicly available webinars that were all very well received. Audiences joined from both within and outside the UK to listen to different speakers each week, and many would catch-up on our YouTube Channel.

MASTS wishes to continue promoting open and accessible marine science discourse and we are pleased to provide with our next round of speakers running until the end of June 2021.

Propagation of Thermohaline Anomalies and their predictive potential in the Northern North Atlantic

We assess to what extent seven different dynamical climate prediction systems can predict winter sea surface temperature. We focus on the pathway where Atlantic water flows towards the Arctic Ocean in the period 1970-2005. Observational studies suggest that there is predictability on decadal time scale in this region. However, predictive skill drops after 1-2 years in the prediction systems and we investigate possible reasons for the poor skill along the poleward pathway.

Modeling zooplankton and fish in space and time, and under climate change

Marine zooplankton and fish species often have very wide, but continuous, geographic distributions in which individuals move or are transported by ocean currents over large distances. They also often have complicated life cycles involving physiologically different developmental stages. As a consequence, species can occur over an enormous range of environments, including food abundance and temperature, in which different life-history stages may respond variably. Combing these considerations in population models capable of capturing the dynamics of such species and their changing spatial distributions in response to changing environments poses serious modelling challenges. This talk will overview the development at the University of Strathclyde of an approach to combining physiological spatial structure in marine population models. Examples will be drawn from modelling and mesopelagic fish, and zooplankton in the Arctic under climate change.

What Happens when Sperm Meets Egg: A Revisitation of the Process

Much of the knowledge on the fertilization process comes from research on sea urchin and starfish eggs that are fertilized in seawater. Even if starfish and sea urchin eggs are physiologically ripe for fertilization at different meiotic stages, their initial response to fertilizing sperm includes virtually the same structural and biochemical changes, i.e., separation of the vitelline layer from the egg plasma membrane and an intracellular calcium increase. Studies from our laboratory have shown that these sperm-induced changes strongly depend on the structural organization of F-actin of the egg cortex, which undergoes restructuration upon sperm-egg interaction. Furthermore, the F-actin remodeling plays a crucial role in preventing the entry of multiple sperm and in ensuring successful embryonic development

Assessing the Impacts of Plastics

Plastic debris is a societal issue of global concern, illustrating the difficulties in balancing the convenience of plastic in daily life with the environmental degradation caused by careless disposal. The environment impacts of plastic extends beyond the end-of-life issues of litter; the carbon footprint of the plastics industry already exceeds that of air travel and shipping combined, and is set to grow hugely in future if current  methods of production and patterns of use continue.

This talk will provide an overview of our work at University of Exeter in determining the impacts of plastics. It will include a summary of the ecotoxicology of microplastics, their entry into the marine food web and the biological impacts this can lead to. The future of plastics is also considered, including how the Circular Economy can provide a more sustainable vision of the future, where new materials and business models are developed and plastics never become waste.
