SUMMARY:MASTS Open Forum Session "Particle Tracking"
DESCRIPTION:The MASTS Numerical and Experimental Hydrodynamic Modelling (NEHM) Forum is excited to host a free Open Forum Session on “Particle Tracking Modelling”. The session will include 2 talks from members of the NEHM Steering Group\, who will give insights into their work: \nParticle Tracking: A powerful and versatile technique for modelling dispersion in the ocean.\nSpeaker: Dr Philip Gillibrand\, Oceanographer and Hydrodynamic Modeller at the Mowi Scotland Ltd Environment Team \nParticle tracking models (PTMs) are powerful tools for simulating the transport and dispersion of material in the ocean. By assigning appropriate properties and characteristics to the particles\, models can simulate\, for example\, the dispersion of dissolved chemicals\, dispersal of living organisms\, settling of particulate wastes and the beaching of floating plastics. Applications include oil spill response\, search and rescue\, academic research and coastal zone management. This presentation demonstrates the ease with which these different processes can be simulated in a PTM. \n~ \nParticle Tracking Modelling: A practical demonstration using OceanParcels\nSpeaker: Soizic Garnier\, Research Officer at the School of Ocean Sciences\, Bangor University \nParticle tracking models are extensively used tools for simulating the transport and dispersion of a large range of particulate material in the marine environment. With their increasing use\, more user-friendly particle tracking codes have been developed and shared within the scientific community. This presentation will introduce one of them\, OceanParcels and demonstrate how to set up and run a simple simulation. \nRegister Here!\nImages: Unsplash

SUMMARY:MASTS Open Forum Session "Biogeochemistry"
DESCRIPTION:The MASTS Biogeochemistry Forum was excited to host this free online Open Forum Session. \nA Recording of the Session is available on the MASTS Biogeochemistry Forum Webpage. \nIs the Ocean losing Nitrogen?\nSpeaker: Marta Santos Garcia\, SAGES\, PhD at the University of Edinburgh \n \nThis talk will explore how ongoing climate change has led to a shift in the biogeochemical status of the Arctic Ocean. Annual nutrient samples from the Fram Strait from 1998 to 2022 reveal that fixed nitrogen concentrations have declined in the polar outflow waters after 2009. Increasing denitrification rates on the Siberian shelves are proposed as a critical driving force behind this change. The loss in nitrogen is likely to continue with the projected decline of sea ice cover and will be key in driving future environmental changes in the Arctic Ocean. \n~ \nTest pilot: Using biomolecular proxies to identify physiological status and feeding history in a large pilot whale mass stranding event\nSpeaker: Anna Kebke\, PhD at the University of Glasgow \nAnna Kebke\, a PhD candidate at the University of Glasgow with the Scottish Marine Animal Stranding Scheme (SMASS) utilizes fatty acids and stable isotopes to enhance our understanding of cetacean ecophysiology and explore their applications in understanding factors in marine mammal stranding events. The focal point of her PhD is the 2023 pilot whale (Globicephala melas) mass stranding event on the Isle of Lewis\, involving 55 individual animals. This mass stranding serves as a pivotal case study for understanding pilot whale ecology in Northeast Atlantic waters and informing Scottish marine mammal management. This research contributes to an international and multidisciplinary investigation that seeks to shed light on the health and ecology of the animals prior to stranding. In this talk\, Anna will present preliminary data from the event with the goal of developing a standardized protocol for incorporating stable isotopes and fatty acids into the routine analysis of stranded cetaceans. \n  \n\nImages:  (1 & 2) Unsplash\, (3) Anna Kebke

SUMMARY:MASTS Open Forum Session "Aquatic Stressors"
DESCRIPTION:The MASTS Aquatic Stressors Forum is excited to host a free Open Forum Session with 2 interesting talks: \nTowards Marine Democracy in Scotland and Chile\nSpeaker: Dr Jeremy Anbleyth-Evans\, Research Fellow at the University of Aberdeen \nDeveloping blue democracy in Britain and Chile means firstly enabling bottom participatory planning\, EIAs and decision making led from the coastal community level. I will explore ongoing research with industrial salmon farming conflict with the economics of biodiversity\, social movements and port coal smelter sacrificial zones\, marine indigenous rights and subsistence fisheries\, small scale versus industrial fisheries and conservation and the challenges of cities and marine protected areas. Methods include interviews\, before and after dive impact assessments\, citizen science baselines / decentralised monitoring\, and participatory mapping. I will attempt to contrast the different systems\, peppered with insights from Japan and Iran to understand how different approaches can support systemic evolution post neoliberalism in Scotland. \n~ \nQuantifying Levels and Intensities of Environmental Stressors across a wide range of pond types\nSpeaker: Prof Frances Orton\, School of Energy\, Geoscience\, Infrastructure and Society at Heriot-Watt University \nSmall freshwater bodies\, such as ponds are likely to be subject to a wide range of environmental pressures due to their small water volume and proximity to anthropogenic structures. In our study\, we sought to quantify intensity of six environmental stressors across these study ponds (n = 80): pollution (metals\, pesticides\, pharmaceuticals)\, eutrophication (nitrate/phosphate pollution)\, the presence of the invasive signal crayfish (Pacifasticus leniusculus: eDNA)\, heat wave occurrence/intensity\, freshwater salinisation and the presence of Perkinsea infection. \n\nOur study encompassed isolated depressions\, ditches\, river floodplains\, wet woodland\, as well as urban and agricultural retention ponds\, located in five geographical clusters in the UK: South-East England\, East Anglia\, South-West Scotland\, Central-West Scotland and Central Belt Scotland. Pond selection was based on estimated anthropogenic pressure and the presence of Rana temporaria\, according to citizen science spawn count data. Predicted anthropogenic pressure levels based on publicly available data did not accurately predict measured levels of pollutions nor eutrophication. Eutrophication levels were generally low\, however\, we found high levels of organic pollutants across all ponds. In particular\, we found high levels of pharmaceuticals\, including illicit drugs (for example\, cocaine was found in 66% of ponds tested)\, anti-biotics (for example\, azithromycin was found in 83% of all ponds tested) and anti-depressants (for example\, temazepam was found in 72% of all ponds tested). Salinity levels were low across all ponds (0.004 – 0.73 psu)\, including those situated in proximity to coastal areas. Analyses of heat wave\, invasive crayfish and Perkinsea infection are ongoing. With these data\, we will profile the levels and combinations of stressors across our study ponds\, to assess their anthropogenic status. \nRegister Here!\nImages: Unsplash\, Pixabay
