Happy #FieldworkFriday! PNSN staff joined colleagues from @waDNR & @waEMD for a canoe trip in the Willapa Bay estuary to view evidence of past Cascadia Subduction Zone tsunamis. We saw sand deposits in the tidal flats, cedar stumps, and tree ring samples—and got very muddy.

Two new camera installs in WA, making these our 2nd and 3rd camera installs of 2026.

📍Newest additions: Ski Badger and Chelan

🔗Watch on ALERTWest.live and Watch Duty

That brings us to 5 cameras across WA!
Do we need a rebrand to PNWHAZ? 🧐

The sun shines brightly over a snowy and icy landscape. Footprints trail out toward the horizon, with a person, very small in scale, at the end of the tracks.

Sometimes, finding old field equipment can be tricky.

If you squint, you can just make out the scientist searching for an old GPS marker at the Pomerantz Solar Observatory, Antarctica, in 2019. #FieldworkFriday

Happy #FieldworkFriday! Station visits in the San Juan Islands are always a treat. This week's visit was made even better by a surprise welcome committee: a friendly ferry terminal café cat on Orcas Island. Coffee, pastry, and a purr-fect start to a long day in the field.

We had a great workshop discussing technical operations to monitor #OceanAcidification! 🧪🌊🦑 #FieldworkFriday #AlaskaSky

#FieldworkFriday: Sometimes the smallest finds tell the biggest stories. 🏺

Douglass et al. explore how sparse artifact scatters can reveal long-term patterns of land use. Using cases from Australia and the US, they show why documenting every the find is key.

Two scientists in cold weather and climbing gear are high on a tower over snow and ice while another scientists looks on from the ground.

Are you afraid of heights? These scientists aren't!

In 2022, CIRES researchers and colleagues scaled a tower to measure the precise heights of instruments installed above the Greenland Ice Sheet. #FieldworkFriday

A black UTV with rolling snow tracks for tires is parked perpendicular to a very snowy trail through a forest.

A wide open field is covered in a thick layer of snow. At the top sits a seismic station, with a large antenna and radio tower to the left.

An antenna and radio tower stands in a snowy field, caked in ice. Behind it in the distance is a large mountain.

Two field staff stand in a snowy field next to a radio tower and a seismic station.

Happy #FieldworkFriday! The mountains around here are finally getting some snow! So when a critical relay station for Mt. St. Helens needed work, we had to bring out the big toys. It took a UTV with snow tracks (and a little bit of snow shoeing) to get to REDMT.

Scientists in winter gear — 2 in red and 1 in blue — inspect equipment in a snowy landscape

Happy Friday! This week for #FieldworkFriday is not fieldwork, but just some birds that were enjoying the evening sunshine in the mountains on my last holiday 😊

A wooden frame holds a metal box, both covered in snow standing in a clearing within a forest. A tall metal framed tower extends upwards behind it.

One of the PNSN field staffers stands in front of the station. It is nighttime, and a bright light from within the metal box of the station shines outwards onto his face, making him glow.

A white catamaran sits next to a dock in a lake on a bright sunny day.

A PNSN field staffer looks inside a metal box suspended on a wooden frame. He is wearing a large, brown puffer coat, green beanie, and a headlamp. It is dark outside.

Happy #FieldworkFriday! Site DREAM is, well... exactly that, a dream. Stehekin although hard to get to, only accessible by ferry, is beautiful no matter the season. With less than a day to work we went into the dark of night & made a final check in the morning after a fresh snow.

Fieldwork is a team effort. 12.5 years ago, CIRES scientists and colleagues were hard at work drilling into sea ice in Antarctica. #FieldworkFriday

The Geologist (alternative title: The Mineralogist) is a painting by the German painter Carl Spitzweg (1808–1885) from the 1860s. It belongs to the collection of the 'Von der Heydt Museum' in Wuppertal/Germany, which acquired it through a bequest in 1913. Spitzweg’s painting style belongs to Late Romanticism. Material and technique: Oil on canvas Dimensions: 44 × 34.5 cm (17 1/4 × 13 1/2 inches) Date: 1852–1856 Picture: Wikipedia / Public domain

⚒ Happy #FieldworkFriday!

The classic: 'The Geologist' by Carl Spitzweg (ca. 1860).

This week we headed to ROXY for a battery replacement and solar controller re-program, swung by RUCH re-program the controller, and wrapped up at SOUA, where we're planning a move! It's getting relocated a few hundred feet and treated to a nice update!

Happy throwback #FieldworkFriday! Fieldwork isn't just maintaining our stations - sometimes we must record the effects that earthquakes have on landscapes and built environments.

Here are some images collected by PNSN and fellow researchers after the Nisqually EQ 25 years ago.

Two people are laying down inside a small, yellow tent with equipment strewn about the snow around them.

CIRES field scientists work hard — and rest hard. In 2012, scientists took a break in their tent during glaciology fieldwork at Tarfala Field Station in northern Sweden. #FieldworkFriday

View from a small fixed-wing plane. A gray-blue strip of the North Pacific ocean fills the bottom edge of the scene. A narrow strip of beach is cut in half by a river emptying into the ocean. Tree-covered moraine rises behind the beach. A lake sits behind the moraine on the left of the image with the edge of the Malaspina Glacier (with alternating bands of dark moraine and white ice) is visible just behind the lake. The front of the St. Elias Mountains sits in the distance. Most of the scene is cloudy, but sun is shining down on the snow and ice of the mountains.

A beach, with grass and trees on the left and mist-covered surf on the right, fills the lower half of the image. The beach is a mix of rocks and sand with some driftwood. A line of tracks stretches long the beach. In the background, the snow and ice covered St. Elias Mountains rise.

A beach with gray sand and rocks. Very fresh bear tracks, with foot pads and claws quite visible, runs down the middle of the dry sand. To the right of the fresh tracks there are additional tracks that are partially worn away. This appears to be a popular bear route.

A yellow survey tripod holds a white GNSS antenna. A large yellow Pelican case at the bottom holds a GNSS receiver. A white garbage bag next to the Pelican case holds a battery to power the station. Vegetation, some of which was prickly, surrounds the tripod. Trees fill the background behind the site.

Going through old field photos and found these from a trip to survey a benchmark near the Malaspina Glacier. When we landed on the beach, we discovered that an unwelcome field assistant had recently come through. The pilot kept watch while I set up the site. #FieldworkFriday #FieldPhotoFriday ⚒️🧪

#FieldworkFriday. Alongside increasingly high-tech methods we use to study the past....the low-tech tools remain key!

A green pasture is filled with a flock of white geese, with many more flying overhead.

A plump green frog sits on a metal ledge inside of the station's enclosure.

A deer stands in a pasture, looking towards the camera.

The station sits in a meadow, with its solar panels resting on a metal frame and facing towards the sun, which hangs in a slightly cloudy sky.

Happy #FieldworkFriday! Frogs, deer, and geese, oh my! PNSN field staff found many animals this week at site HILL, where they replaced the solar charge controller. The frogs at the station are still seismologists-in-training, but we're "hopping" they can help next week, too!
