LAGOS Visualization Blog

Welcome to the LAGOS Visualization Blog. Here we will post interesting and fun visualizations of data from LAGOS as well as other posts that we find interesting to share and talk about. In this blog, we focus mostly on data visualizations because it is not easy to fully capture the complexity of macroscale data, which includes a range of environmental characteristics

Water quality observations through time in LAGOS-NE by Nicole Smith

This animation shows the accumulation of water quality observations for each of the lakes in the LAGOS-NE database. For each year and lake, the  cumulative count of in water quality observations to date is shown by color. The first field observation in the database was recorded in 1933 from Lake Pepin (WI/MN). The lake with the most data points across

LAGOS-NE: The people behind the scenes to create an open database

We are thrilled to announce that the LAGOS-NE data paper is published, which means that the underlying data are live:  https://academic.oup.com/gigascience/article/doi/10.1093/gigascience/gix101/4555226 Creating something like LAGOS-NE takes a wide range of contributions, expertise, and types of work. We want to extend a HUGE thanks to everyone who contributed. This effort could not have happened without the willingness of people to work

Map of the continental-scaled controls of summer CO2 in lakes by JF Lapierre

These maps are from a recent paper by JF Lapierre et al. that compared the factors that control lake CO2 at the continental scale. He found that the spatial patterns in lake pCO2 driver‐response relationships translated into the formation of spatial clusters of pCO2 “regulation” that are shown in map (e) even though there is little apparent regional pattern in pCO2

The freshwater landscape. By Emi Fergus

Emi Fergus et al. published a recent paper that describes the complex features of the freshwater landscape. These maps are very compelling in that they show that there are very different patterns between freshwater ABUNDANCE versus CONNECTIVITY. FIGURE DESCRIPTION (Figure and text from Fergus et al. 2017): Freshwater abundance and connectivity maps by system type. Freshwater abundance is quantified as

Change in lake chlorophyll distribution in thousands of US lakes through time by Sam Oliver

This figure shows the distribution of the underlying data in Oliver et al 2017 (see below). Interestingly, when you look at all data, it is difficult to discern any patterns. While the study found that on average lakes weren’t changing in chlorophyll, roughly 15% of lakes were either increasing or decreasing in chlorophyll. Samantha Oliver made this GIF using data
