RT @USGS: What if the Fantastic Four worked at USGS? . We may not wear capes, but our scientists bring real-world superpowers to the field….

Water is everywhere, but how much do you really know about it? From the depths of the ocean to the water flowing from your tap, we’re sharing 5 fascinating facts that you may not know about water! #WaterScienceWednesday #USGSWaterScienceSchool

USGS is a leader in understanding key knowledge gaps and frontiers for how we assess lake ice. By combining different sources of data, we can begin to understand how lake ice might be changing from local to continental scales. Learn more:

#USGS researchers are studying lake ice changes by combining data from remote sensing (f), cameras (c), drones (d), models (h), radar (b), and field-based measurements (a). To achieve efficient analysis, harmonizing diverse data resources is essential.

For example, in 2011 it was estimated that ice anglers spent ~$240 million US dollars (USD) on ice fishing equipment across the US. With reduced ice cover, thick ice that is safe for human safety is expected to decrease by 80%.

#DYK that over half a billion people live near seasonal ice cover?. Up to 18.4% of the world’s lakes > 0.1 km2 are anticipated to not freeze in the future. These resources can represent critical economic hotspots.

USGS monitors phosphorous in waterways across the country to help communities tailor nutrient-management strategies for their local areas. Learn more about the P in your water - #WaterScience #WaterAvailability

July is #LakesAppreciationMonth - #DYK @USGS conducts research in lake settings? Limnology - the study of lakes and other freshwater systems - is the science that provides improved understanding of lake ecosystem dynamics & information that can lead to sound management policies.

❄️Reduces the severity of lake-effect snow (C).🦠Curbs algal growth over winter (E).💨May limit carbon gas release (B). Learn more - #LakesAppreciationMonth #Lakes #WaterScience.

It's July, and most Northern Hemisphere lakes are ice-free, but ice coverage has surprising benefits. Lake ice:.🎣Boosts winter recreation & commercial opportunities (A, I).🐟Provides crucial habitat for coldwater species and under-ice algae (H, G, F)

Happy Birthday, Florence Bascom! 🎉The first woman hired by the #USGS in 1896, she is a pioneer whose work is still used today. Imagine mapping the geology of the North Atlantic and Appalachian region by hand – Florence did just that!
