Marine Heatwaves – Trends, Impacts Attribution, and Software

For the week of 15 October 2018

Join us Tuesday, October 23, 2018 at 4 pm US EDT / 1 pm US PDT/8 pm UTC - Wednesday, October 24, 7 am Australian EST for a webinar on Marine Heatwaves – Trends, Impacts Attribution, and Software by Alistair Hobday of CSIRO and Eric Oliver of Dalhousie University. 

Extreme climate and weather events shape the structure of biological systems and affect the biogeochemical functions and services they provide for society. There is overwhelming evidence that the frequency, duration, intensity and timing of extreme events on land are changing under global warming, increasing the risk of severe, pervasive and in some cases irreversible impacts on natural and socio-economic systems.  Climatic extremes also occur in the ocean, and recent decades have seen many high-impact marine heatwaves (MHWs) –anomalously warm water events that may last many months and extend over thousands of square kilometres. A range of biological and economic impacts have been associated with some intense MHWs. We will cover historical and projected trends in these events, and the role of attribution for communication and mechanistic understanding. Growing public interest in marine extreme events means that measuring the severity of these phenomena in real time is becoming more important, and we propose a method for consistent description of MHWs that is compatible with an underlying long term trend. Finally, we will demonstrate software that is available for use to study or follow MHWs in your area of interest.

Dornoch Firth: Extinct oyster reefs restoration starts

The endangered European oyster is trying to make its way home. This is not the doing of researchers or scientists, but was kick started by the Glenmorangie Distillery which sits above the Dornoch Firth. Dornoch Firth historically was home to a large European oyster reef that has since been farmed away. The owners of Glenmorangie Distillery hope to replant this reef to use as a natural filter that will help to clear any discharge created through the distilling process. (via BBC)

Ecosystem restoration: What if we build it, but they don’t come?

In the October issue of MEAM Contributing Editor Tundi Agardy discusses the philosophy behind ecosystem restoration. What does it mean to restore when we can't truly bring back what is lost? She writes, "We can reintroduce foundational species, but cannot begin to restock the system with the myriad microbial, plant, invertebrate, and vertebrate species that were once there. We built it, but they don’t come…." (Read More Here)

Researchers recommend satellite technology as a way to create more effective, 'true' shark sanctuaries

Researchers went to a shark sanctuary in the Republic of Marshall Islands (RMI) to study reef sharks but ended up exposing illegal fishing instead. What the researchers found were tagged sharks traveling through at higher speeds and closer to land than expected, as if being carried away by boat. The researchers thought of a solution to this problem: tracking all boats within the RMI. This way they would know where the boats are and what they are fishing for. Sometimes it’s not the animals that need tagging, it’s the people. (via

How can we restore marine ecosystems? Perspectives and tips from global experts
