high-precision GPS unit
A high-precision GPS unit (on white "T" in foreground) records its position at a ground control point along Pohoiki Road. This marker was painted in July 2018 and is visible in numerous aerial photographs taken by USGS Hawaiian Volcano Observatory geologists throughout Kīlauea's lower East Rift Zone eruption last summer.

Mangrove forest dominated by Bruguiera gymnorrhiza
Mangrove forest dominated by Bruguiera gymnorrhizaMangrove forest on the island of Pohnpei, Micronesia, dominated by Bruguiera gymnorrhiza (locally called sohmw).
The USGS and partners are studying how mangrove forests in the Federated States of Micronesia may respond to sea-level rise over the coming century. Their projections will help Micronesian communities plan for the future.
