Favourite websites: OCEARCH.org Global Shark Tracker

Ever wondered where great white sharks get to when they’re not peering in at cage divers or dining on hapless seals? Well, the answer is on the OCEARCH website: for several years now, great whites and other apex predator sharks have been tagged and their locations recorded every time they surface and send a ‘ping’ to the satellite tracking system.

It’s a fascinating glimpse into the lives of these magnificent creatures: there are tagged populations off the East Coast of the United States, the West Coast of South America, and the South African coast. The researchers have named all the sharks, and my favourite is Lydia, a great white shark.

Lydia is a very well-travelled shark: earlier this year she headed east from the eastern seaboard of the US to the middle of the Atlantic. To the very middle, in fact: for several weeks in March and April she swam down the line of the Mid Atlantic Ridge.

It’s fascinating to see where the sharks go, and how far and how quickly they travel.

OCEARCH is a wonderful organisation, undertaking research vital for the conservation of these beautiful creatures. Here’s a little about them, from their website:

‘OCEARCH enables the brightest scientists in the world by giving them approximately 15 minutes of access to live, mature great white sharks (and other species) to conduct up to 12 studies including tagging and sampling. OCEARCH captures mature sharks that can range between 2,000 and 5,000 pounds on average, maneuvers them onto a 75,000 lb. custom lift, then releases the shark after researchers have completed their 15 minutes of work. The shark is guided by hand in the water on and off the lift. OCEARCH is a leader in collaborative open source research, sharing scientific data and dynamic education content in near-real time for free to the public through the Global Shark Tracker, enabling students and the public to learn alongside PhDs.’

Hurrah for OCEARCH, and hurrah for open source research: it’s not just the scientists who benefit.

Favourite websites: Kittenwar

Kittenwar is another of my favourite websites. It’s a real time sink if you are a cat lover (like me): once you start looking it’s hard to stop.

Basically photos of two kittens/cats are shown side by side, and they ‘do battle’ as you vote for the cutest. The ‘winningest’ kittens and their stats are listed (hint: take a photo with your kitten’s paws and tubby tummy in full shot and you’re in with a chance), as are the ‘losingest’ (hint: if you have a sphinx or angular-headed Siamese, your darling is going to be on this list …)

I put up a photo of one of our two fudsies, Ballou, on 12 January 2006, and in those eight and a half years she has done battle 4,235 times. Her stats are a pretty steady 49% won, 39% lost and 13% drawn. I think she’s the cutest thing ever in the photo I entered, but that’s because I know she’s enjoying having her ears rubbed and is not being tortured, as it rather looks like …

Ballou. Kittenwar warrior. Not being tortured, honest.

Favourite websites: APOD

After a couple of gloomy posts about the poor hedgehogs, I thought I should feature something wonderful and lovely and spirits-raising. And so … here’s a mention of one of my favourite websites to brighten things up: NASA’s APOD site, otherwise known as the Astronomy Picture of the Day.

It pretty much does what it says on the tin: every day it features a wonderful photo to do with the skies above us. Sometimes they are Hubble space telescope shots, sometimes they are photos by the legion of talented amateur photographers who photograph our skies by both day and night, sometimes they are photos taken from the International Space Station; whatever the source they are invariably beautiful shots that fill me with wonder and joy.

I am completely unscientifically-minded, but I love learning about the natural world about us, whether it is the worlds beyond our planet, or the geology and meteorology of our own. NASA has some fantastic websites, and this is one of my favourites. Click on the links in the text written by professional astronomers that accompanies the photos, and have a truffle round in the archive (link at the bottom of the APOD page)—you’ll lose hours but you’ll learn so much!
