The first measurements are running and more will follow soon!
NuClim aims to determine the baseline of greenhouse gas concentrations in the North Atlantic. We look at radon, greenhouse gases and a range of other parameters at the ENA observatory (Azores) and @maceheadccaps.bsky.social (Ireland).
A map in shades of blue showing the North Eastern Atlantic with light arrows mostly from south west to north east and highlighting the Graciosa Island in the Azores and Mace Head in Ireland. A big cloud in the top left corner, containing the text "measurements of air masses without human influence". Around the text, icons for pressure, methane, gamma radiation, wind, carbon dioxide, particulate matter, carbon monoxide, eddies, ozone, rain, radon and temperature are arranged. The cloud is connected to the two measurement stations by a kind of flow-y triangle. In the top left corner the project's logo and two hands holding an earth and radiation sign in grey are placed. In the bottom right corner small text says: "Wind data from E.U. Copernicus Marine Service Information (DOI: 10.48670/moi-00181), map data from Natural Earth".

Sometimes fieldwork and travel is disturbed by unexpected happenings. When Scott was at Graciosa to set up the radon detector, the airport was shut down for half a day because the President of Portugal visited the island. This caused Scott to stay an additional night.

The UAc team carried out the seasonal water sampling in the bay of Calheta, Santa Cruz do Graciosa, taking samples at different distances from the shore to see how conditions change.

On this, a range of bags, tubes and penshaped sensors and other unidentifiable things are placed. One woman is sitting in front of it at seems to take some notes.

The UAc team arrived on Graciosa in the morning with all sampling and laboratory equipment and proceeded directly to the ENA station. There, a potential new collaborative experiment with Dr. Xuemeng Chen (@helsinki.fi) was discussed.

Two weeks ago, our colleagues from Terceira (University of the Azores, UAc) were getting ready for their second trip to Graciosa Island! The team led by Joana Barcelos e Ramos do seasonal sampling of the marine community and carbonate system.

In addition to the measurements at Mace Head, we are also measuring at the ENA station on Graciosa island (Azores, Portugal). It's the Eastern North Atlantic (hence ENA) atmospheric research station established by Atmospheric Radiation Measurement (ARM) User Facility.

ICOS celebrates its 10-year anniversary this year, but some of our stations have around for decades before this. Long-term #greenhousegas measurements are needed to analyse both long-term #climate trends and extreme events. 🌎🌪️

Photo of an open transporter with a big metallic box and a smaller blue plastic box on top in it. In the fronts some blankets and gloves are places and behind the box some blue barrel is barely visible. Photo of a woman in a yellow jacket and light brown curly hair explaining something next to a metallic box about half her height. In the fron a rack with sme tubing and a machine and some plastic covers of similar size is placed.

We’re happy to announce that the radon monitor upgrade arrived last week at @maceheadccaps.bsky.social.
This marks an exciting milestone in our efforts to characterize background air masses and improve understanding of greenhouse gas sources and transport.

Photo of the inside of some big metal box with many cables, tubes and a little rack on the right side. In the lower left corner a grey big barrel is labelled "Filter". The whole box is wrapped in some purple-red plastic cover and sits on transport pallet.

The Atmospheric Research Station at Mace Head @maceheadccaps.bsky.social ist located on the west coast of Ireland (Carna, County Galway). It offers a unique exposure to westerly winds coming from the North Atlantic Ocean into Europe.

How does radon tell us about how air moves and mixes?
And what is the goal of our project?
The figure is a two-part drawing. The main colors are different shades of blue and a dark orange. The top part is titled "Radon originates from land". In it many arrows are moving from left to right. They have the same color dark orange color as "radon" in the title. They are on top of symbols for wind. Some arrows end, some start but overall the number at each horizontal position remains the same. On the bottom, arrows seem to originate from a dark blue rectangle in the same color as "land" in the title. In addition, on it are placed little icons showing an industrial facility. On the right side of the figure, a location marker is set into the air. In it, a a scale indicates a high value and it says "radon" below the scale. The bottom part is titled "Radon disappears over sea". The overall layout of the second part is very similar to the first. However, the right two thirds of the bottom do not have the rectangle but waves in a lighter blue (the same color as "sea" in the title). From it only very few and small arrows originate. The arrows in the air are similar to the previous ones on the left side, on the right side however, there are fewer arrows beginning, so the overall number of arrows decreases. The scale in the location marker shows a low value.

At Graciosa, the daily commute on foot to the ARM station always included extra time to pat the goats and donkey.

Photos: Scott Chambers
Photo of a donkey amidst dry grass and brown earth. The donkey seems to be walking and looks into the camera. In the background some green shrubs and the sea are visible. The sky is blue with some scattered clouds. Photo of two white goats between grass and shrubs. The goats stand behind each other. The goat further away looks directly into the camera, the other one to its right side.
