MOST RECENT

I was a hot mess yesterday (I started the day by burning my oatmeal. TWICE), so I never managed to put together a #30shadesofscience post. I promise I’ll do a make up post sometime in the next few days. TODAY was a much better day (you’d never guess it snowed yesterday). I noticed that there were some septa that needed replacing on my gas piezometers when I visited my study site on Saturday, so I gathered my trusty sample bag, and ran out to change them today. .
.
These guys are just 1/2 inch PVC with slots cut into the sides of the bottom and a rubber septa on top. I inserted them into the soil at various depths. The gas in the pipe will equilibrate with the soil gas at the bottom openings after a day or so, and I use a syringe to pull gas out of the tubes and then run that gas on a Gas Chromatograph to determine the CO2, CH4, and N2O concentrations in the soil at various depths. This is a great low-tech (and low-cost!) way to get CO2 samples from the soil while I wait for good conditions to deploy my automated gas sensors. .

The New York Times published a new article on carbon sequestration in agriculture practices. It features many well known soil scientists from our communities and is a little nugget of hope in today’s news reel :)

After nearly ten years of hard work, the magnum opus of my dissertation was accepted in #JACS ! #Thermophile #Exobiology #Astrobiology #Biogeochemistry #Biology #Electronics #ScienceTheEarth

After 6 hours at the Quazar science center studying various kinds of Chemistry.... It’s time for a mental break before my lab tonight. Minerals of the genetic code. The physical, chemical and biological connection. The plant pharmacology genetic periodic chart. What medicine do you need? I can make a blend based off the chemical makeup of plants. What are you deficient in? Selenium deficiency, also known as Cancer. The list goes on. .

Collecting soil pore water from those lysimeters I showed y'all last week! My gross chipped, soil-filled nails are becoming a theme of my Instagram account.

It’s hard to tell now, but soon these little electrodes will be measuring redox potential and pH! #voltammetry #electrochemistry #soilbiogeochemistry #biogeochemistry #soil #soilscience #laboratory #chemistry #science #mini #getsmaller #microsite #little #digdeeper

Rain *grumble* mud *grumble,grumble*. The hydrologist and farmer in me loves a good water year, but the field scientist in me needs 5 solid days of sunshine to dry out the fields enough to drive equipment up the hills and deploy my gas probes. I wear a lot of different hats as a Biogeochemist, and right now the field scientist hat is controlling my mood. I’m getting a ton of indoor work done while I wait for the weather to cooperate, but I’m so impatient to start collecting pCO2 data from the field! In an ideal world I’d be able to capture all of the changes that are occurring out in the field as we go through the change from spring to summer, but sometimes we just have to work with what we have. It sure is frustrating, though!

Planktonic foraminifera (colloquially “forams”) are notoriously difficult to culture in the lab. They are incredibly sensitive to disturbance, and require careful and prompt feeding after collection from the water column to ensure their survival. As a consequence, there are only a handful of labs in the world which manage to successfully culture them, and one of them is at the Inter-University Institute of Marine Sciences in Eilat, Israel, where grad student @sophiejgill visited recently, and where this microscope photo was taken.

Foraminifera are probably most famous in Earth Sciences due to their use in palaeoceanography, because the calcite they make their external shells (tests) from records the conditions in the seawater at that time. In sediment cores, once planktonic forams are fossilised, their spectacular calcite spines are not preserved. However, when they are alive, these can be seen clearly using a microscope (but can also be seen with the naked eye!) when the forams are healthy. The species shown in the image above is Globigerinella siphonifera, and there are two individuals here. The life habit of planktonic forams is poorly understood, but their reproduction may be linked to the lunar cycle (!), and their life span is approximately 7 days. As one of the major calcifiers in the surface ocean, more research into how planktonic forams will be affected by climate change, acidifying oceans and geoengineering schemes aiming to enhance ocean alkalinity are important to investigate.

I made a thing! My handmade CO2 sensor does exactly what it’s supposed to do! I’m so excited to bring this to work tomorrow and share with my colleagues. I had a busy weekend learning to build and program this sensor/datalogger combo, but I’m so glad I decided to go. These little devices are potentially game changers for my research into carbon cycling, I’m already thinking of all the places I can deploy low cost CO2 sensors. This was the first of these workshops, but it was a huge success, so for those in the biogeochemistry world, look forward to more workshops in the future. Maybe at GSA? #handbuilt #sciencecrafts #weekendwarrior #carbonscience #climatechange #biogeochemistry #engineeringenthusiast #30shadesofscience #30daysofinstascience #scicomm #actuallivingscientist #girlswhoscience

Today I’m building CO2 sensors and attaching little data loggers to them. I learned to solder! I put together circuit boards! It was a very exciting (and somewhat frustrating) day, all in the name of science. It’s always good to learn a new skill, and I’m so excited to be able to make and deploy my own CO2 sensors in the future! I don’t think people realize how many side skills scientists often learn in order to stretch our research dollars as far as possible. Today was a good day of learning some useful new skills.

This huge fiber in the MilliQ tubing was giving us some "interesting" peaks on the flow injection analysis today! 😂

It’s raining (again) which means that I won’t be getting my carbon dioxide sensors deployed in the very soggy soil any time in the next week. Since I can’t control the weather, I’m focusing on getting my equipment 100% ready for deployment, checking programming, getting the GC running, and getting the lab stocked. As much as I want to start collecting data, I’m at the mercy of the weather for now, something farmers and scientists have in common. #30shadesofscience #30daysofinstascience #datacollection #weather #scicomm #biogeochemistry #soilscience #climatescience #agriculturalscience

Cleaned out some old and crusty lysimeters today with @benjamindillner . We'll use these to sample soil pore water. We're excited to FINALLY get back in the field after this long Winter!
