If you haven't done it yet, I would advise everyone to take a gander at Dave's landslide blog and his amazing posts and photographs of some of the aftermath from the Chinese earthquake last year. Below is my favorite (the trucks near the bottom give you a sense of scale).
Well, there another meme in the geoblogesphere, what do you have with you in the field (seesomeotherposts).
I bet mine is going to be a little different because I have so many tools, I can't take them all into the field at one time! Clothes Well, I guess it depends on the weather, but the constant is chest waders. Sure, you may be able to get away with hip waders, but I always manage to get water down my leg in them. Ok, the beard is constant too, but it isn't as integral.
Equipment Now we get into the good stuff. First, lets do some discharge. How about a nice velocity meter? I use a flowtracker that automatically does the discharge calculation for your, depending on your method (.6, .2/.8, ice surface, etc). Well, there are always wells. Will probably need an electronic well tape (beeps when the end of the tape hits water). We can't forget about the actual chemical make up of the water. For "everyday" sampling I will be using a Hydrolab water quality sonde. We have to communicate with all this equipment, so we need a computer that can handle some dirty and wet field sites. Looks like a job for a toughbook. Last, but not least, a rite-in-the-rain notebook. I am playing around with water.
With the news of a "new island" of formed by the Hunga Tonga-Hunga Ha’apai volcano in the south Pacific getting some attention in the geobloggosphere, I thought for this return to Map Monday, why not look back at another "recently created island". Surtsey is probably the most famous example of a undersea volcano reaching the surface. It has since become an important "natural experiment" of colonization of life.
The above image is a geologic map of Surtsey by the The Surtsey Research Society. The principle craters, vents, fissures are denoted by red lines. The purple colors shows various lavas, browns are tuff and tephra, and the tans are talus slopes and sand deposits.
