i wandered lonely as an iceberg

I was going to write about how the scientific publishing system works. I was also thinking of maybe doing something about “climate change” versus “global warming” and how they are not interchangeable as terms of reference. Then something cool happened on the news last night. They had a story about this big iceberg B17B that is floating of the Australian coastline (admittedly a long way off...but still).

This news piece showed an interview with Neil Young. It totally freaked me out for two reasons. The first being that the berg itself originated in one of my research study areas and secondly because he was my first boss! Like proper boss. Serious boss. He use to scare the crap outta me to tell the truth.

That job was awesome though. I forgot how much i liked it. It was with the glaciology department. Glaciers are what icebergs are calved from. They are totally interesting. My very first project was using computers to analyse satellite data to auto identify (and later track) icebergs. There are a LOT of icebergs and they move in mysterious ways.

One of the things you can do is use them as free buoys. I have an image here which shows the path that individual buoys took that were deployed at the mertz polynya. They cost a lot of money and are hard to deploy (well, tricky). The buoys showed the behaviour of the sea ice (which is what we were interested in) In a similar fashion you can use the bergs to track ocean currents, find grounding zones etc. Like i said cool. Well, i think it is cool.





I loved the research that the glaciology department did (still does). Floating ice shelves. Drilling ice holes to find out what was underneath the floating ice shelves. Accumulation versus loss for given glaciers. In fact studying every little inch of them. That’s what was great about being the computer programmer/scientist. I got to see a little bit of interesting research over a lot of fields.
Until last night i had totally forgotten about that. About all the fun i use to have. I think i am going to make that my new years resolution. To get back some of the wonder and fun i use to have.

If you want to know more about icebergs etc. Feel free to ask. I am in quite a chipper mood.
