USGS scientist Jennifer Miselis stands on board the US Army Corps of Engineers' (USACE) Lighter Amphibious Resupply Cargo (LARC). USGS collaborated with USACE to analyze coastal change due to Hurricane Sandy. Miselis is preparing to deploy a Chirp sub-bottom profiling system with a towfish attached in between the pontoons to collect sub-seafloor geological data.

Waves wash over a road on Roi-Namur Island, Kwajalein Atoll in the Republic of the Marshall Islands, during a particularly high tidal event. USGS is studying how slightly reduced rainfall combined with sea-level rise affect freshwater sources on low-lying Pacific coral islands.
