Unfortuntately, due to a family illness today, I am behind on my posting somewhat but never fear, for I still have quite a bit to talk about! I’ve been attending all sorts of talks and exhibits, taken lots of photos and talked to lots of people, so expect posts for the next week or so. In the meantime, here are some of my photos!

Notice anything odd?
It’s a huge pumpkin thrown in the Leith River on Campus! Good old students and their hijinks…

Head on down to the Otago Farmer’s Market today from 9.00am, the weekly market with a great range of fresh produce, and the team from the Food Science Department will be there to test your tastebuds. Hopefully you can guess what you’re eating, I sure didn’t know what the mystery flavour drink was at the Food Science display at the University Expo on Friday.
Oh, and try the crepes at the market, they’re well worth the wait!
At the top of the harbour, there’s a little area called the Anderson’s Bay inlet. Originally it was twice the size until Dunedin’s growing population demanded more land! (And so half was ‘reclaimed’, although shouldn’t it just be ‘claimed’ since no-one had ever claimed it before?)
Anyhoo, I’ve lived in Anderson’s Bay all my life and spent many hours as a kid poking at crabs, feeding ducks and jumping on the dead octopii. More recently, through an interest in photography, I took note of all the bird life that visits the inlet but even I wouldn’t have thought that there was up to 16 different bird species that visit or live in the inlet area. Someone else had taken notice though.
Jill Hamel of the Save the Otago Peninsula group organised for an artificial bird roost to be constructed in the inlet as a refuge for the birds from people and canines in May 2009.
This is possibly one of the first examples of an artificial roost in the world and after a slow start (just the ducks and the gulls) there are now up to 8 species at a time on the roost, usually at higher tide.
The Anderson’s Bay Inlet Roost has become a resource for seeing the natural world up close and this is similar to what one of my fellow Science Communication student is working on.
Tess Bunny is advocating the notion of “ReWilding the City” and currently has an installation at Wall Street which you should head along and check out. I’ve asked her to do a guest post, so that should be coming your way shortly!
Stuff you always wanted to know about water!
Water quality is linked to water consumption, e.g. how drinkable, and/or available, water is depends on how we are using our water. If we suck it out of the ground faster than it can be put back (which is happening all the time), then it can become full of minerals and salts, which aren’t very good for plants and soils. If we contaminate places where there is fast moving groundwater, like in underground caves, water will become quickly polluted elsewhere.
Surface Water and Groundwater
The water that we see on the surface (known as surface water), like lakes, streams and rivers, only accounts for ~1.5% of all the water in rocks and sediments underground. This groundwater can surface as a spring, supply water to surface streams and lakes (usually below the water level) and even flow as streams in underground caves.
While surface water tends to be cloudy with sediment, groundwater is relatively clear and is a good source of drinking water for communities and individual dwellings. In dry regions, groundwater may be the major or only source of water.
This is the amount of running water on the ground when there is a rainstorm, and depends on the maximum rate that soil and other surface things can soak up water. If it’s able to soak up water as fast as it falls, there is no runoff but when it is not as fast or the soil fills up, the extra water collects at the surface, and hey presto! Runoff!. Of course, if this occurs on a hill or slope, down it goes either into streams or rivers.
It’s Day 2 of the Scifest and I hope you’ve got heaps planned but if you’re new to the area, just visiting or otherwise, here are some local attractions tied in with the Festival:
Cadbury World Sensory Tours
Delectible and Disgusting Trails at the Otago Museum
Appetising Astronomy at the Beverly Begg Observatory
Belly Business at the Dunedin Public Art Gallery
Monarch Wildlife Tours
Another great video from They Might Be Giants, so much better for kids than the Wiggles!!
Science is real – don’t let anyone tell you different 🙂
