Marine Heatwaves – Trends, Impacts Attribution, and Software

For the week of 17 September 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.

New Genetic Research Shows the Legacy of Fish Farm Escapees

New tests have discovered interbreeding between escaped farm salmon and native salmon stocks in Newfoundland due to the 2013 Cooke Aquaculture pen collapse in that area. This was not the first, nor the last of pen collapses for Cooke Aquaculture. During the summer of 2017, where over 260,000 farmed salmon escaped into Puget Sound, Cooke stated that survival of the escaped fish was low and interbreeding was impossible. The same statements were given in 2013. Obviously those fish did survive and found a way to flourish. (via Hakai Magazine)

Scientists Gave MDMA to Octopuses—and What Happened Was Profound

Dosed with a small amount of MDMA, octopuses display similar acts as expected by humans. When given to seven octopuses, the usually loner beings piled together showing affectionate touching and even “dancing”. This research suggests that our human brain chemistry and that of octopuses may be more alike than we previously thought. (via Gizmodo)

Angry at plight of southern-resident orcas, speakers rebuke NOAA in public meetings

With the most recent loss of J50, only 3 years old and one of the two females born in her generation, there is reason to be upset. NOAA officials have known about the plight of the residential whales for some time and the public feels they have not done enough with that knowledge. With the death of J50, and the too soon departure of J35’s calf, NOAA officials hope that only progressive change will come from this low point. (via Seattle Times)

Environmental groups release results of three-year project that shows how Arctic being altered by climate change

Canada’s Arctic Marine Atlas is a new extensive online toolkit created to aid in the protection and study of Canada’s arctic. Covering topics from sheet ice thickness to location of mines, this toolkit serves to provide information for free for use by the general public and academic researchers. (via The Globe and Mail)
