Well, well. Contour us surprised. Who doesn't love a good map or two? And our topographic ones only scratch the surface (as it were). At @USGS, we do all kinds of #mapping: subsurface geology, coastal hazard risk, land use...and yes, maps of the seafloor: ow.ly/OW7450WjJAf

The #USGS is actively #mapping the #seafloor in coastal to deep sea environments. These maps provide the scientific foundation needed to address national priorities, including #publicsafety, #nationalsecurity, and #economicprosperity. 🌊✨ow.ly/wnbI50WgXw1 #OceanMonth

What is a pocket beach? (Hint: it's not a cute name for the sand that ends up in your pockets after a beach day.) New @USGS #remotesensing research finds that these short, sandy stretches between headlands along the CA coast rotate seasonally: ow.ly/h3jl50Wpi0J

New projections of #shorelinechange by @UHManoa and @USGS finds that 81% of sandy shorelines on the island of #O‘ahu could be lost by the end of the century, with nearly 40% of that loss occurring within just the next five years: ow.ly/YS3h50Wow7R

Coastal communities around the world face increasing threats from #stormsurge — intense rises in sea level caused by powerful storms pushing water ashore. New research finds that storm surge likelihood is greatly underestimated along U.S. coasts: ow.ly/pgVL50WlJzT

A new #USGS study investigated the decomposition of #saltmarsh organic matter and found significant production of dissolved organic and inorganic #carbon and #methane, which supports export from #marshes to the #ocean. 🌿✨Read the study: ow.ly/U1t050WhB26.
