Sunset at Sage Lot Pond Salt Marsh Observatory marks the end of 16 hour field effort. During this sampling, USGS researchers captured the exchange of materials between the marsh and estuary. This field site provides infrastructure to keep sensors deployed nearly year-round so changes across seasons and extreme events, such as large storms, are captured.

High Tide
High tides are one challenge of working in tidal wetlands! Here the marsh platform is completely submerged during a spring tide. The boardwalk, which scientists use to access the site, is also under water during this extreme high tide, while the solar panels powering some instruments remain dry.

A brief overflow of Kīlauea's summit lava lake on Oct. 16
On Saturday, October 15, Kīlauea Volcano's summit lava lake overflowed the vent rim between 1:00 and 2:00 p.m., and again around 6:30 p.m., HST. In this image, captured by HVO's K2 webcam, you can see small spill-overs (shiny black lava) on the east (far left) and west (right) sides of the vent rim.

Vilano Beach, FL: Dunes, decks and boardwalks swept away
Vilano Beach, FL: Low altitude oblique aerial photographs taken before Hurricane Matthew (Sept. 6, 2014) and after (Oct. 14, 2016) show that storm waves and currents eroded a 16-foot-high san dune, exposing old seawalls and washing away boardwalks and decks.

St. Augustine: storm waves wipe out dune, open new inlet
Low-altitude oblique photography taken before Hurricane Matthew (Sept. 6, 2014) and after (Oct. 13, 2016) shows the storm cut a new inlet between the Atlantic Ocean and the Matanzas River, stripping away a 3.7 meter (12-foot) dune and carrying sand into the estuary.

Streamflow measurement in the fall
Hydro Technician, Henry Witt, takes a self portrait while he conducts a discharge measurement in the Houstonic River at Falls Village, CT. One of the many perks of field work year round is the ability to witness the seasons come and go.
