 Hi, everyone. My name is Donald O'Leary. I'm a research scientist on the science education team here at NEON. And today I wanted to give you a brief overview of NEON's spatial design and geospatial data. So let's get started. First of all, NEON has separated the Conterminus 48 states, Alaska, Hawaii, and Puerto Rico into 20 different eco-climatic domains. Now this was done using a multivariate clustering analysis of such factors as incoming precipitation, average annual air temperature, and other ecologically important factors. And after we distinguished this area into 20 different domains, we found the locations for each one of our field sites that best represents the variety of climate and ecology that can take place in those domains. So for places such as the Northeast, those field sites are really very representative of the entire region. However, for places like the Desert Southwest and the Colorado Rockies and Plateau, those reasons are so incredibly diverse that each one of those field sites is not entirely able to represent the entire domain. So that concept of representativeness does vary throughout our observatory. And it's something to take note of when you're applying our information for your own research. So we have several sources of NEON's spatial data, including our spatial data in maps and our field site information. I've kind of shown how to navigate to those through our navigation options on our web page and the blue text there. You will download coordinates with data as you get it either from our data portal or through our API. And if you want higher precision UTM, Easting, and Northing coordinates, those are available through our geoneon package. There's a good tutorial on how to use that if you search geoneon on our website, but I won't get into that too much for right now. So let's talk about our aquatic field sites. First of all, we have three different types of field sites and two different types of moving water field sites. We have our streams and our rivers. These are set up in a fairly similar way, except that for our streams, the ones where we can have a field scientist walk across them, we have an upstream and a downstream sensor in these sites. And we also have riparian assessment strips, these kind of dark green transects across the stream. Where our scientists go through and collect observations on the different types of flora and fauna that exist in those in those zones. We also have groundwater wells and this blue square is a meteorological station that we have across this reach of stream. If the stream gets too big and it's not safe for someone to walk across, then we call it a river. And we'll have a buoy out in the middle of the river instead of our upstream and downstream sensors. But otherwise, the field site layout for streams and rivers is fairly similar. However, for our lakes, things get a bit different. We have a buoy again in the middle of the lake and generally the lake's deepest location. But we have two other sensor sites with these yellow circles with an L in them. The L here stands for the littoral zone and these sensors are in places close to the edge of the lake where sunlight can actually reach the bottom of the lake. And illuminate the subsurface there. So these lakes also, of course, have groundwater wells and meteorological stations, as well as our riparian assessment zones surrounding them. Our terrestrial field sites switch things up a bit where we have our tower indicated in the blue square here. And the tower's prevailing airshed defines the region where we monitor our tower base plots and some of our soil base plots and our soil array. We have a very intensive monitoring location nearby the tower, but then we also have these distributed sites across the field site. So these little white squares are our distributed base plots and those occur across all of the different land cover types, as is indicated by the background covers on this map here. Let's talk a little bit more about our terrestrial observed data. So one aspect of this is our small mammal trap. So we put out a grid of small mammal traps in these different sites and you can use the GeoNeon package again to get highly precise eastern and northern coordinates for each one of these traps. We also do a vegetation survey where we measure all of the trees greater than 10 centimeters dbh in 40 by 40 meter plots across all of the tower and distributed base plots. Our terrestrial instrument data is also very interesting. Most charismatically, we have our instruments located on our Neon Flex Towers. These towers are designed to be a bit taller than the vegetation that they're monitoring, so they are at different heights depending on each ecosystem. And each one of these towers has multiple levels above the ground where we collect information and that's located in the Z offset attribute of each one of these data sets. Our soil plots measure in the opposite direction where they're going down into the earth and this number five here is a soil moisture sensor. He's a zoom in on our soil moisture sensors. You can see that we have different monitoring locations at different depths in the soil surface. This is also represented by that Z offset in the depth in meters for these measurements. So that is our brief overview for now. Of course, we have much more information available on our website and if you ever have any questions, feel free to reach out to us. Thanks for your time.
