Adelaide Coastal Waters Study - South Australia's illegitimate child.
December 15, 2016

Time to shut down tabloid journals and Academic Doping
19 August, 2016 
The academic and research communities are being swamped under a tsunami of junk journal invitations promising rapid publication in their "prestigious" publications.

Ten Simple Rules
June 21, 2016 

Statistics may be everywhere, but they aren't always understood, calculated, or communicated effectively. After a suggestion from the ASA, a group of leading statisticians penned "Ten Simple Rules for Effective Statistical Practice"  to help researchers avoid pitfalls of misrepresenting data or formulating hypotheses based on faulty statistical reasoning.

Joe Gani on CSIRO
June 10, 2016 
Professor Joe Gani was a distinguished mathematical statistician and was Chief of CSIRO's Division of Mathematics and Statistics between 1974 and 1981. In a 2008 interview he reflected upon his CSIRO years. What's extraordinary is how very little has changed with respect to CSIRO's penchant for change!

As we've long been advocating - it's time this endless, unproductive cycle of deconstruction and reconstruction ceased (or at least had a longer return period).

If you think all the current rhetoric about CSIRO needing to become more relevant, more commercially focused and 'customer' driven is new, reflect for a moment on Professor Gani's experience more than 40 years ago.

Climate Science on the Skids

CSIRO CEO, Dr. Larry Marshall makes another extraordinary claim.

New paper published
May 25, 2016 
Professors David Fox (Environmetrics Australia / University of Melbourne) and Wayne Landis (Western Washington University) respond to renewed calls to retain the NOEC in ecotoxicology.

Larry Marshall - Same dog, different leg action
April 11, 2016 
Although CSIRO has a new CEO in Larry Marshall, the 'innovation' rhetoric and restructuring is not. You'd think that with the passage of 10 years, the organisation (indeed any organisation) would be reaping the benifits of structural change. Regrettably, CSIRO never got off the slash and burn treadmill.

Statisticians and (eco)Toxicologists Unite!
January 5, 2016 
As debates about the legitimacy of NOECs and NOELs continue unabated, we believe it's well and truly time to establish a sub-discipline of Statistical (eco)toxicology.

Revised ANZECC Guidelines officially released!

BIG data is watching you
November 6, 2014 
Ron Sandland recently wrote about the new phenomenon of 'big data' - weighing up the benefits and concerns. Terry Speed reflected on the same issue in a talk earlier this year in Gothenburg, Sweeden noting that this is nothing new to statisticians. So what's all the fuss about?
Here's another take on the 'big data' bandwagon.

Marine Ecotoxicology: Current Knowledge and Future Issues

Chapter 2 : Contemporary Methods for Statistical Design and Analysis by David R. Fox

http://environmetrics.net.au/web_images/Marine%20ecotox.jpg Julian Blasco , Olivia Campana, Miriam Hampel, Peter M. Chapman

Academic Press, 1 Sep. 2016 -  342 pages

Marine Ecotoxicology: Current Knowledge and Future Issues is the first unified resource to cover issues related to contamination, responses, and testing techniques of saltwater from a toxicological perspective. With its unprecedented focus on marine environments and logical chapter progression, this book is useful to graduate students, ecotoxicologists, risk assessors, and regulators involved or interested in marine waters.

As human interaction with these environments increases, understanding of the pollutants and toxins introduced into the oceans becomes ever more critical, and this book builds a foundation of knowledge to assist scientists in studying, monitoring, and making decisions that affect both marine environments and human health.

A team of world renowned experts provide detailed analyses of the most common contaminants in marine environments and explain the design and purpose of toxicity testing methods, while exploring the future of ecotoxicology studies in relation to the world’s oceans. As the threat of increasing pollution in marine environments becomes an ever more tangible reality, Marine Ecotoxicology offers insights and guidance to mitigate that threat.
