[draft intro] The Anthropocene highlights limitations in existing frameworks for data collection and analysis with the suggestion that researchers have run up against the limits of the knowable. This has been revealed in a number of ways: an inadequacy in existing techniques to analyze a changing and uncertain future, challenges to the way in which researchers frame human activities relative to environmental transformation, and the politics that inform what questions can be asked. How are artists and researchers associated with Mississippi. An Anthropocene River project engaged in explorations of the limits of the knowable, and what role does the concept of the Anthropocene have in prompting such questioning? This data sensing device was developed in collaboration with the Mississippi. An Anthropocene River project and Mississippi Studies.

Works with Dweetpro.io (for live IOT data sharing), Freeboard.io (live data visualization of data) and SFTP (for archiving and backup). This code was written for a device consisting of the following hardware, but the code is modular, allowing you to remove sensors depending on your needs:
- Raspberry Pi Zero (https://www.raspberrypi.org/blog/raspberry-pi-zero/)
USGlobalSat BU353-S4 USB GPS Receiver (https://www.thegpsstore.com/USGlobalSat-BU353-S4-USB-GPS-Receiver-P3219.aspx)- Ultimate GPS with USB - 66 channel w/10 Hz updates (https://www.adafruit.com/product/4279)
- 9-DOF Accel/Mag/Gyro+Temp Breakout Board - LSM9DS1 (https://www.adafruit.com/product/3387)
- BME680 - Temperature, Humidity, Pressure and Gas Sensor (https://www.adafruit.com/product/3660)
- Waterproof DS18B20 Digital temperature sensor + extras (https://www.adafruit.com/product/381)
- Water quality meter (pH, DO, NO3, turbidity, salinity)
- Digital flow meter

- Leg 0 (Coffee Pot Landing, Lake Itasca, MN to Iron Bridge, Bemidji, MN) (8/30/2019-9/2/2019)
- Leg 2 (Genoa, WI - Lock and Dam number 8 to Bad Axe, WI)
- Water temperature is not accurate for Leg 2 (no effective way of putting the probe into the water from Voyageur canoes).
- Crew list is not accurate (removing for following legs).
