Baffin Bay and the west coast of Greenland currently 20-30°C above average air temperature. Climate means are currently around -25°C for much of this area, but above freezing today past 76°N latitude.

Always nice when your photo quickly snapped to document current conditions when sampling turns out to be a nice photo on its own. Clohogue Brook in the Wicklow Mountains, Ireland.

Managed to take two precip samples during Éowyn to analyze for water isotopes. Coupled with sampling at two other Dublin sites and our vapor isotope monitor as part of our project ISO-TAISE, we should get some nice insight into the moisture fueling the storm.

This Met Éireann forecast for the winds on the Aran Islands off Co. Galway and Co. Clare are insane. This feels a bit like when I saw the US National Weather Service forecast a global record high for Death Valley a few years back. You follow the models, but it still feels weird to predict records.

I feel like this photo on a BBC news update perfectly encapsulates our current society’s approach to fighting climate change, on so many different levels.

Our water vapor isotope analyser here in Dublin is still in "test" mode while we get all the specifications fixed, calibrations working properly, and deal with some ongoing inlet condensation issues. But hey, it's still nice to see test data for the past 2.5 months!

The planet and the U.S. are both running record-warm for the year-to-date period. My monthly global climate summary: yaleclimateconnections.org/2024/12/nove...

The year 2024 is virtually certain to be Earth's second consecutive warmest year on record.

Random discovery of the day: my academic great-grandparent is Marjorie Sweeting!
Also, my academic grandparent (Derek Ford) unsuccessfully tried to get posted to Thule, Greenland, and Antarctica early in his career. I managed to stumble into extended projects at both places.
Academia is weird.

As of 9-10 pm local time in many Nordic countries, the reported air temperature is STILL above the old daily record at 5 sites and tied with the record in 6 other sites.

Oh man, a lot has changed here in the month I've been away. Hello to new followers, and I hope you like seeing field photos of bogs and water in Ireland! Seen here: the glacially formed Upper Glendalough Lake in the Wicklow Mountains, Ireland, only a valley away from one of my main study areas.

🧪 I’m happy to announce that my project ISO-TAISE: Isotopic Tracing of Atmospheric Rivers and Irish Storm Extremes was funded by EPA Ireland as part of their Research Call 2023. This project will gain insight into extreme Irish precipitation events through water isotopes.

🧪 What a difference a month makes in the Antarctic summer! The French research station Durmont d'Urville is located on an island, but sea ice lets a supply road connect to the mainland (photo). As of 28 Nov, the sea ice was still intact, but a month later the islands are close to being free again!

In lieu of a standard report, I gave students the option of doing something creative to express their sensory & emotional impression of our visit in a Mallorca cave. The goal was to explore alternate ways of conveying information not captured by data.
1st submission is a 17 min techno 😆. Let's go!

Always remember to filter your water samples before geochemical analysis! For example, water isotopic analyzers and ICP elemental analyzers do not handle full grown tadpole shrimp well 😉!

🧪 Having fun with tracking where the moisture that produces precipitation is coming from using HYSPLIT backtrajectory modeling. Here's where the water vapor originated for over 100 precipitation events in Indiana, colored by region and sized by relative contribution to the precipitation.

🧪 First step to studying where precipitation comes from is to define the source areas! Here's my broad physiographic sources for the NARR model domain. The product of a couple weeks finding, reassigning, & typology fixing online GIS data...& swearing at whoever made the error-filled originals.

Autumn comes quick to the Arctic. At Pituffik, Greenland, the sun sets for the first time in four months in the last week of August, then night grows by 20-40 min each day. By mid-September, autumn color has ended (Arctic willow seen here in late August) and soon everything refreezes until next May.

New methods paper on ammonium isotopes in ice! Alexis Lamothe, a PhD student in my former lab in France, developed a technique for analyzing the isotopes of ammonium at very low concentrations. It's a challenge on many fronts, but he outlines a consistent way to success here!
An extraction method for nitrogen isotope measurement of ammonium in a low-concentration environment
Abstract. Ammonia (NH3) participates in the nucleation and growth
of aerosols and thus plays a major role in atmospheric transparency,
pollution, health, and climate-related issues. Understanding its ...
