Hydrologic Technician Sharon Mulready checks equipment on electrical power tower and site 372750122012701 Coyote Creek near Alviso Slough. The tidal gage is located at the confluence of Coyote Creek and Alviso Slough, and is accessible only by boat. The estuary is fed by the Sacramento and San Joaquin Rivers, and various tributaries in the Central Valley.

In September of 2019, a 315 ton iceberg known as D28 broke free from the Amery Ice Shelf in Antarctica. The berg has a surface area of more than 600 square miles, roughly comparable to the size of the Hawaiian island of Oahu. It's the largest iceberg to calve from the ice shelf since the 1960s. (Imagery captured by Landsat satellites.)

USGS Hawaiian Volcano Observatory and DOI Office of Aviation staff prepare the sampling mechanism (on blue tarp) and inspect the Unmanned Aircraft System (UAS) just before it took off to collect water from the Halema‘uma‘u crater lake.

The Unoccupied Aircraft System (UAS) that collected water from the crater lake in Halema‘uma‘u on October 26 was outfitted with both visual and infrared (thermal) cameras. This reconnaissance video shows fumarolic activity on the walls of the crater. Fumaroles appear light in color (yellow and white) in the visual imagery due to alteration of the crater wall rock.

In this October 26 reconnaissance survey, the Unoccupied Aircraft System (UAS) reaches the northeast part of the Halema‘uma‘u crater lake, where large rocks at the lake margin are often used to visually track the rising water level. Taken over a period of about 5.5 minutes, the survey is shown at 3 times the speed it was filmed.

Prior to the Unoccupied Aircraft System (UAS) mission that collected a water sample from Halema‘uma‘u at Kīlauea's summit on October 26, reconnaissance UAS missions were flown. This video, taken over a period of 15 minutes, has been sped up 7 times to show the UAS as it approaches Halema‘uma‘u from the southwest.

The sampling mechanism (on blue tarp) is prepared and the Unoccupied Aircraft System (UAS) is inspected just before take off to collect water from the Halema‘uma‘u crater lake. Brightly colored flagging tape tied to a cable attached to the UAS indicated depth as the sampling tool was lowered into the water.

The dynamic landscape and climate of Alaska presents many challenges to the over 200 communities that live in rural areas of the state and have a wide variety of resource needs. Coastal and riverine erosion, flooding, wildfire, permafrost dynamics and increasing temperatures act as drivers for many of these landscape changes.

On November 15, 2019, USGS HVO field engineers rapidly deployed a new data-telemetry hub near Pu‘u ‘Ō‘ō. A crack near an important telemetry hub at near the summit of Pu‘u ‘Ō‘ō was observed to be growing over the past several weeks and HVO field engineers prepared a contingency telemetry hub to install nearby if necessary.

This instrument, the Edgetech SB-516 or "chirp", emits acoustic signals that penetrate the sediment on the seafloor. The reflected sound is recorded and is used to create a cross-section image, or profile, of the sub-bottom.
