Coral Woman and Q&A with special guest Uma Mani

Join us for a film screening of “Coral Woman” with Q&A with special guest Uma Mani. This is a filmmaker’s journey with Uma, an artist who paints coral reefs, a certified scuba diver, exploring the underwater world & the threat to coral reefs of Gulf of Mannar, India. Born in a traditional family in Tamil Nadu, 53 year old Uma, a homemaker, has been trying to bring attention to this alarming environmental issue through her paintings. It is, in fact, these corals that inspired Uma to learn how to swim, dive & paint in her 50s. Coral Woman is about Uma’s efforts to address the threat to coral reefs from bleaching, industrial pollution and climate change. The screening will take place on Tuesday 28th December at 1300 GMT, followed by a Q&A with Uma Mani! Please register below for the link and occasional updates and join us for this very special event.

Baseline characterization of species assemblages in Ecologically and Biologically Significant Area – Placentia Bay

Today Shreya Nemani and Julia Mackin-McLaughlin, MSc students at the 4DOceans Lab of Memorial University, gave an intriguing and thought-provoking seminar about their coastal benthic habitat mapping work in Placentia Bay, Newfoundland and Labrador, Canada as part of Fisheries and Oceans Canada’s Coastal Environmental Baseline Program. Their work at the 4DOceans lab of the Marine Institute aims to advance understanding of seafloor heterogeneity and assess the spatial and temporal variation in species distribution. They study the spatial distribution of seabed habitats in Placentia Bay. In addition to studying the composition of faunal assemblages, Shreya is also studying their functional composition and diversity of the bay. Concurrent with this research, Julia has modelled the ecological niche of two habitat-forming algal species which support various ecosystem services for the west coast of the bay. We would like to cordially thank both Shreya and Julia for a fascinating talk.

Cometh seaweeds, cometh structure in marine habitats

Pleased to invite you to a seminar by Dr Kathryn Schoenrock, who is the EPA-Ireland, Primary Investigator and Postdoctoral Researcher at National University of Ireland (NUI) Galway, on Tuesday 27th July at 1300 BST. The webinar is entitled “Cometh seaweeds, cometh structure in marine habitats.”

She obtained her PhD (Biology) in 2014 from the University of Alabama at Birmingham where she investigated the ecology and physiology of Antarctic Seaweeds, with an emphasis in chemical ecology and climate change effects. She has since worked extensively in south-western Greenland trying to understand the diversity of kelp forest and coralline algae habitats, but her experience with climate change and the marine region drew her to the Lusitanian region of the North Atlantic where marine communities mirror projections for the Boreal region under present climate change regimes. She currently works on creating a baseline for marine monitoring in kelp forest communities found in western Ireland, and works closely with citizen science outlets, science festivals, and commercial organisations. She is originally from California, and has studied marine ecosystems (especially those structured by seaweeds) from Antarctica to Greenland for over 15 years.

Strange world of hydrothermal vents

A hydrothermal vent is a fissure in a planet’s surface from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart, ocean basins, and hotspots. Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Common land types include hot springs, fumaroles and geysers. Under the sea, hydrothermal vents may form features called black smokers. Relative to the majority of the deep sea, the areas around submarine hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids. Chemosynthetic archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp.

The Endeavour Mid-ocean Ridge is an exciting study location because it is a place where new volcanic seafloor is constantly created at the spreading boundary between the Juan de Fuca and Pacific plates. The region (approximately 300 km off the British Columbia coast), has been the site of intensive investigation for more than 20 years.The Ocean Networks Canada Observatory, comprising VENUS and NEPTUNE Canada cabled networks, supports transformative coastal to deep ocean research and technology. It enables real-time interactive experiments, focused on ocean health, ecosystems, resources, natural hazards, and marine conservation. The Observatory is a national facility led by the University of Victoria for a pan-Canadian consortium of universities and partners.

NEPTUNE Canada’s real-time monitoring capability will benefit both ongoing and new experiments. Continuous data gathered before, during and after events like earthquakes and intrusions will be recorded across a coordinated suite of instruments both at the hydrothermal vents on the seafloor and within moorings extending 250m up into the 2,200m water column. A network of seismometers here and at other sites will provide high resolution information on tectonic processes such as earthquakes and strain across the Juan de Fuca plate.
