Wooster’s Fossils of the Week: Ordovician bioerosion trace fossils

Wooster Geologists | 9 December, 2016
This week's post is a celebration of the appearance of a remarkable two-volume work on trace fossils and evolution. The editors and major authors are my friends Gabriela Mángano and Luis Buatois (University of Saskatchewan). They are extraordinary geologists, paleontologists and ichnologists (specialists on trace fossils). They led this massive effort of multiple authors and thousands of manuscript pages. Turns out they are inspiring scientific leaders as well as sharp-eyed editors.

the resilience of Las Vegas and water

Inkstain (John Fleck) | 9 December, 2016
When I was writing my book, I wanted to talk about water use in cities through the story of a single city, and I chose Las Vegas (Nevada, not the one in New Mexico) intentionally as a rhetorical device. One of the writer's tricks is to start readers on familiar terrain and lead them to a new and different place. Las Vegas and its reputation for profligate excess is familiar terrain for a lot of people. I wanted to start there and lead readers to rethink their ideas about what counts as resilience, to rethink Vegas.

Chilly Field Days This Week

A bit work pressed. Had a few chilly days in the field this week trying to get a couple sites in before snow arrived. And I got a little taste of the Fraser outflow as well.

Explosion kills 33 at Inner Mongolia coal mine.

Sciency Thoughts | 8 December, 2016
Thirty three miners have been confirmed dead following a gas explosion at a coal mine in Inner Mongolia, China, on Saturday 3 December 2016. The incident happened at about midday, local time, at the Chifeng Baoma mine in Chifeng (or Ullanhad) in the southeast of the province. Over a hundred and thirty men were bellow ground at the time of the incident, the majority of whom were able to escape. Thirty three miners were unaccounted for following this initial evacuation, all of whom were later found dead by rescue teams.

HiRISE: Coolest landscape on Mars or Earth

Red Planet Report | 8 December, 2016
Many Martian landscapes contain features that are familiar to ones we find on Earth, like river valleys, cliffs, glaciers and volcanos. However, Mars has an exotic side too, with landscapes that are alien to Earthlings. This image shows one of ... Co...

A 100-year-old mystery blob solved

Deep Sea News | 8 December, 2016
First, let's be clear: in the ocean, mucous is king. On land, mucous is tragically confined to various animal orifices, unable to last long outside a moist environment. But in the ocean, slime is everywhere. And perhaps no animal has done more with 'snot' than the larvacean. Larvaceans are shaped like tadpoles, and most are pretty small, about as long as a rice grain. These tadpole-shaped animal have a big mucous complex: each larvacean lives inside its own little ball of goo (usually about as big as a marble), which it secrete from its skin like a disembodied nose with tail attached. The mucous "house" in which the larvacean resides captures particles much the way your nasal snot captures dust. And then the little larvacean slowly sucks in this snot, digests out the particles, and poops out little pellets. But just because an animal eats its own mucous for a living doesn't mean it lacks sophistication. And nothing illustrates this point better than a 100 year old snotty mystery, solved by modern science.

HiRISE: Painting with frost

Red Planet Report | 8 December, 2016
Subtle variations in color look like brush strokes as the lightly frosted terrain reflects light. These variations provide a backdrop to some exotic features referred to colloquially as "spiders." The radial channels branching out from a central ...

The tropical Pacific Ocean keeps it's cool as La Niña persists

ImaGeo | 8 December, 2016
Last month's forecast of a continuing La Niña has panned out, with cool sea surface temperatures persisting across most of the central and eastern equatorial Pacific Ocean. It's a weak La Niña, and in all likelihood it will peter out by March, if...

why would anyone not trust the author????

I have already shown that ordinations of the Lake Żabińskie fossil assemblages are weirder than you ever imagined possible. Now it is time to look at figure 2 of Larocque-Tobler et al (2015) which shows an ordination of the chironomid assemblages in the modern Polish-Canadian calibration set with lakes colour-coded by temperature. A number of lakes are marked as "misplaced", that is their temperature differs from neighbouring lakes in the ordination. This figure should be easy to replicate with the archived data.

Photo of the Week – Salt Coral

Geosphere | 8 December, 2016
The photo posted below is a really cool one. Interestingly, enough I have been getting into podcasts lately. They are great during my bus ride to and from work every day. One of the podcasts that I like is Neil de Grasse Tyson's Star Talk Radio. Anyway, the other week Star Talk had a pretty good discussion about salt and the role it has played in developing human history. Check out the episode in two parts here. Arguably as one of the most important economic minerals of all time, although it may not seem so today.
