Toronto Harbour sampling: winter edition

Last summer, Waterkeeper collected 166 samples from the Toronto Harbour. We learned quite a bit about our harbour, including where some of the more polluted spots are and just how high the bacteria levels can get. You can see the full results of those samples here.The main thing we learned was the need to continue sampling. The summer program showed that we don’t have enough information to truly grasp the sewage situation in the harbour.…

More precise SEG-Y?

The impending SEG-Y Revision 2 release allows the use of double-precision floating point numbers. This news might leave some people thinking: "What?".Integers and floatsIn most computing environments, there are various kinds of number. The main two are integers and floating point numbers. Let's take a quick look at integers, or ints, first.Integers can only represent round numbers: 0, 1, 2, 3, etc. They can have two main flavours: signed and unsigned, and various bit-depths, e.g.…

Solar Impulse – à regarder de près

L’émission Découverte est parmi nos meilleurs (avec Les années lumières) pour suivre les travaux scientifiques (j’hésite de parler de «progrès» scientifiques pour des raisons qui apparaîtront dans l’article qui suit). Pendant la dernière année, Découverte a couvert par deux émissions (reprise de la première le 5 février dernier, le deuxième le 12 février, curieusement manquant sur le site) les travaux pour faire la circonvolution du globe en avion solaire sans recours à l’énergie fossile, finalement réussie…

Behind the scenes of “Be Prepared”

Springtime is supposed to signify new beginnings and a fresh start, with the attitude of “out with the old and in with the new”. However, for many field biologists, spring is a fairly stressful time. While you are still writing up the results from the previous field season, you are also supposed to be planning for the next. A lot of “behind the scenes” work occurs in the planning process – all of which ends up being represented by…

Monday reads

New reads, hot of the press. Very diverse spread of application, news and research.Ten years of barcoding at the African Centre for DNA barcodingThe African Centre for DNA Barcoding (ACDB) was established in 2005 as part of a global initiative to accurately and rapidly survey biodiversity using short DNA sequences. The mitochondrial cytochrome c oxidase 1 gene (CO1) was rapidly adopted as the de facto barcode for animals. Following the evaluation of several candidate loci…

I’m a #reallifescientist

It’s been a while since my last blog post, and I’m about to deviate even further from my normal routine by sharing a rather personal post. OK, a very personal post.  But as someone who values science advocacy and outreach, I feel this post is nonetheless important to share with both the general public, and young aspiring scientists. I think one of the triggers that has caused me to write this post has been this…

150 things about Canadian palaeo, part 7 – Current Canadian Palaeos (1) #FossilFriday

Who are some of the current Canadian palaeontologists? A few weeks ago I introduced you to some of the early figures in Canadian palaeontology, but the field has grown substantially, and there are a lot of Canadian palaeontologists, and people working on palaeontology in Canada now. This is going to be the first of a few posts, since there are so many! Starting at 43/150, in no particular order, the first 8 current Canadian palaeos:…
