 Hi, I'm Ryan Schwingle from the New Mexico Institute of Mining and Technology. I'm in the electrical engineering department at New Mexico Tech. Working as an undergraduate researcher in Dr. Pullin's lab at the environmental chemistry lab at New Mexico Tech. Well, it's a dynamic lab space that we've built. It's really one of the first of its kind to ever be constructed and then deployed, especially in a watershed as pristine as the Viagrande here. We've got the National Instruments Realtime Controller, which handles all of the data acquisition and control of all of the systems within the trailer. And then, you know, some auxiliary devices in addition to a cellular modem and a router for external communications so we can control the trailer from pretty much anywhere in the world. And then we've got our first piece of equipment in the lab, which is our OI Analytical Online Carbon Analyzer, which allows us to look at organic carbon and inorganic carbon in the freshwater system. It is wired up to the Realtime Controller, so any readings that we get from it is automatically saved, along with various troubleshooting data, et cetera, et cetera, to a USB thumb drive, which can be accessed from anywhere in the world. The most important bit, the air conditioner behind you, to keep this metal box nice and clear. For the winter, we've got three different heaters on board. The primary is actually in the air conditioner. It's a heat pump, so the air conditioner runs in reverse in the winter time, and it tries to cool the outside air, bringing all that warm air in here in the event that it becomes too cold for that to work. There's also a 1700 watt heating element in that heater. In the event that that can't keep up, we've got a radiant heater up front. In the event that we lose power and we still need heat, there's a propane-fired heater located underneath, and there will be two 20-gallon propane bottles mounted up front on the tongue of the trailer in the winter time. On the sample line and the return line going out towards the stream, there's also heat tape, spiral-wrapped all the way down in the tube in the conduit, hopefully located below frost level. So in the winter, it shouldn't freeze. I really enjoy building instrumentation, and the thing that I find incredible is, as a WE, you can create instruments that are used everywhere and that are actually needed. In our lab, we are creating instrumentation that no one else has done, and that's pretty exciting, especially when it lets us know a little bit of how the climate is changing and everyday parameters that affect all of us. We all obviously need drinking water, and the water from the hammers eventually ends up in the Rio Grande, which everyone filters and drinks. We are making a difference one drop at a time. Future work in the trailer will include several additional instruments in this lab space that we've got here. Since we've deployed it in the last couple of days, we're still working out all the kinks, and we're realizing, oh, we really need this fitting here and that fitting there. So this whole thing is going to be changing in the coming months, and hopefully the next time you come back, you'll be able to see a bunch of additional instrumentation and a little better finished lab space.
