A Sub Sampling The Alkaline Fluids Of The

A sub sampling the alkaline fluids of the Arnarnesstrytun shallow-water vent, Iceland.

We’re in the field for a 10 days long diving expedition to explore the geochemistry and microbiology if shallow-water alkaline hydrothermal vents in the north of Iceland. The area, known as the Strytan vent field, is composed of several chimneys, with the main chimney standing 54 meters tall from the seafloor. The 75°C hot alkaline fluids (~10 pH) mix with the cold (8°C) fjord waters, creating strong thermal and geochemical gradients that support microbial communities.

The team is composed by an international group of geoscientist that includes United States, Italian and Japanese researchers with diverse backgrounds.

Viewing The Eclipse From Douglas Wy My Brother

Viewing the eclipse from Douglas, WY.

My brother took this picture during totality, showing a large prominence on the upper right limb.

What an amazing sight!  I hope you got a chance to experience totality!

Outreach While Exploring The Rockies An

Outreach while exploring the rockies -  An impromptu outreach event happened at the mushroom rock formation in the Rocky Mountain National Park at an altitude of ~12,000 ft. Solar scientists talked to fellow park-goers about the upcoming Eclipse (Aug 21) and told them all about how to safely use the Eclipse glasses. We are students from different universities around the world that attended the UCAR Heliophysics Summer School in Boulder, CO. They and some more people got to see the solar disk with the eclipse glasses that we carry with us wherever we go! Picture taken and submitted by Aparna V (Georgia State University). In the picture from left are Camilla Harris (University of Michigan), Mariangela Viviani (not seen) (Max Planck Institute for Solar System Research), Saida Castillo (Universidad Nacional de Colombia) and Lee Gunderson (Princeton University).  Date: Aug 6, 2017
Howdy Were On The Island Of Galveston Tx


We’re on the island of Galveston, TX right now studying summer convection with cool new phased-array radar technology. We were the lucky early morning crew to take DOW8 out to capture the rapid growth of this towering cumulus cloud. Our radar scans a six-beam volume in 7 seconds, which is insanely fast!

Did anyone remember the donuts?

Hej Hej A Swedish Greetings Were Out Here

Hej hej! (A Swedish greetings), 

We’re out here in Stordalen mire, a peatland underlain by discontinuous permafrost in the Swedish arctic!  Look at us basking in arctic rays and avoiding the plagues of mosquitos.Or not.  Here we’re processing cores taken in these peatland lakes to help understand how aquatic vegetation affect methane dynamics and how this might affect global carbon budgets with increasing permafrost thaw in these northern peatlands.  

Hejdå! (goodbye)

Best wishes and warm regards from the field,

As Part Of An Effort To Monitor The Earthquakes

As part of an effort to monitor the earthquakes triggered by reservoir loading, we installed two portable seismographs of the neighborhood of the La Romaine 3 reservoir in the Province of Quebec, Canada.  The La Romaine hydro-electric complex involves the construction of four dams by Hydro-Québec.  The digitizer is located in the black container and it is connected to three short period seismometers to the left.  The backdrop of the picture is the 95 m high La Romaine 3 dam (located at latitude 51.12 N; -63.42 W). The 38 km2 reservoir filled up very quickly following snow melt in early May 2017.  As of July 18th, 2017, only a few small reservoir-triggered earthquakes have been recorded.

Hello Agu Just Back From A Long Day In The

Hello AGU, Just back from a long day in the field. We’ve been running a seismic survey of Pretty Lake, Indiana for a summer research project to complement some continuing paleolimnologic analyses. The field crew managed to get the gear broken down and packed back into the trailers just as the sun was setting. Now it is time to go rehydrate. Wish you were here!

Dear Agu Hello From Sunny Hot And Humid

Dear AGU, 

Hello from sunny, hot, and humid Baltimore! Not all fieldwork involves far-flung exotic locals- I’m putting up thermometers around the city to better understand urban microclimates, the urban heat island, and our city will respond to climate change. In this photo, I’m hanging a iButton thermometer in a tree on the East side of Baltimore’s in the Broadway East neighborhood. 

Happy field season, 


Hi All Greetings From Svalbard At A Latitude Of

Hi all,

Greetings from Svalbard, at a latitude of 78° North. Our cloud campaign, part of (AC)³ project, is about to come to an end. During more than 80 flight hours for each research airplane, Polar 5 and Polar 6, we have sampled very different and exciting cloud situations. While Polar 5 takes care of the remote sensing measurements, Polar 6 flies inside the clouds, mostly collocated with Polar 5. We also overflew the Research Vessel Polarstern (see photo). With only a couple of flights left, the campaign is nearly finished. We are confident that the collected dataset will take us to relevant scientific results. So far, the campaign has been awesome and it has let us experience the grandeur of the Arctic (for instance, flying above the glaciers was amazing!).

Best regards!

Greetings From The Ice Factory This Photo Is

Greetings from the ice factory,

This photo is from the katabatic winds of Terra Nova Bay in the Ross Sea, where we just completed a 65-day cruise – the first winter cruise in the Ross Sea in nearly 20 years! Katabatic winds are strong, persistent winds that lead to this area being referred to as the ice factory. We experienced hurricane force winds (over 70 knots), waves nearly 10-feet high, and lots and lots of sea ice production. This project (PIPERS; Polynyas, Ice Production and Seasonal Evolution in the Ross Sea) will help us unravel the story of winter sea ice formation and the associated production of and Antarctic Bottom Water, which drives circulation of the world’s oceans. 

Do you wish you were here?
