Check out Margarita’s chemostat setup to examine shifts in nutrient quotas in Galapagos diatoms throughout diel cycles. She will be sampling every three hours over the next two days!! 🥱

Are water levels in wetlands important to you? @kica22.bsky.social's new paper in GRL shows that the SWOT satellite can measure water surface elevations in the Everglades with a mean absolute error of 6.7 cm. Check it out! agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Scientific figuring with three panels. Left panel shows a map of the Everglades in Florida overlaid with data from the SWOT mission. It shows very detailed water level data throughout the everglades. The second panel, in the upper right, is a scatterplot showing in situ gauge water level against SWOT water level. It shows a mean absolute error of 6.7 cm, a correlation coefficient of 0.996, and a mean bias of 6.8 cm. The third figure, a scatterplot in the lower right, shows that by averaging 30 or more SWOT pixels, high accuracy is possible.

Please join us tomorrow morning to celebrate Aundre Jackson as he defends his Master's thesis! While at UNC, Aundre's research has focused on the question, to what extent does V. fischeri use T6SS weapons to invade an already colonized territory? See you at 10:30 am tomorrow in Murray Hall or Zoom!

Congratulations to PhD candidate Lauren Grimley on her recently published paper, Climate change exacerbates compound flooding from recent tropical cyclones, in NPJ Natural Hazards! doi.org/10.1038/s443... @natureportfolio.nature.com

Screenshot of Figure 6 from Grimley et al. (2025). Fig. 6 The maximum extent of compound flooding for Hurricanes Florence, Floyd, and Matthew (left column) and the frequency of an area experiencing compound flooding across the future ensemble simulations (right column).Areas flooded by individual processes (e.g., rainfall, coastal) are not plotted. The entire domain is shown in the top panel and the black rectangle highlights the location of the Wilmington metropolitan area which is shown in the bottom panel. Present-only is in pink, future-only is the maximum extent of compound flooding across the full ensemble in orange, and both present and future is in blue. Darker red colors indicate a higher probability of compound flooding occurring in the future across all ensemble members. In the future, the model results show an expansion of compound areas further inland and a widening of the floodplain for all three storms.
