Sondas de oxigênio e ORP (Oxygen and ORP probes)

Estou me preparando para ir para a Antártida.

Uma coisa que quero entender é como a química da água vai mudar durante o longo inverno. No verão, a fotossíntese produz oxigênio. Mas no inverno fica escuro por meses e não há fotossíntese. Outros organismos usam oxigênio todo o ano todo. Quero medir como o oxigênio na água muda do verão para o inverno e para o verão do ano que vem. Vou usar sondas de “O2” e “ORP” que vou deixar na água por um ano. Comprei sondas de O2 caras porque essas medições são muito importantes. Comprei sondas de ORP baratas e eu preciso construir-las. O primeiro passo é substituir seus conectores. O video baixo e no Instagram mostra o processo de substituição dos conectores.

I'm preparing to go to Antarctica.

One thing I want to understand is how the chemistry of the water changes during the long winter. In the summer, photosynthesis produces oxygen. But in the winter, it is dark for months, and there is no photosynthesis. Other organisms use oxygen all year. I want to measure how the oxygen in the water changes from summer to winter to the following summer. I will use O2 and ORP probes that I will leave in the water for a year. I bought expensive O2 probes because the measurements are important. I bought cheap ORP probes and I need to put them together. The first step is to switch their connectors. The video below and on Instagram shows how I changed the connectors.

Day 14 in Antarctica

Image
December 10, 2013 Today was sunny all day with 25 knot katabatic winds in the afternoon.  It was warmer. I spent all day on microscopy, photography, and sorting photos.  It was a very productive day. The quad bike quit starting, and Devin, Anne, and Tyler pushed it back to camp.  None of them new what to do to figure out what was wrong.  I got ready to help when Ian came back to camp.  He has a lot of experience with engines, and once we found the tool kit and pulled the spark plug, we solved the problem:  the plug was fouled.  A new one fixed the problem.  We can add "engine repair" to the list of field skills needed! Our only means of transport besides walking is a quad bike (ATV).  We have a sled to help carry gear between the huts/sleeping tents and the science tent and dive hole.  It is also good for carrying the drill and other gear around the lake.

Toothpaste Freezes

There are so many little things I didn't think of before the first time I went to Antarctica that make a difference.  I like having clean teeth, so brushing twice a day is very important to me, even in the field.  I can handle dirty hair, but not dirty teeth. It's hard to brush your teeth when your toothpaste is frozen into its tube. That small hole at the top requires the toothpaste to deform to get out. And that part gets cold the fastest, often getting clogged with a plug of toothpaste ice. This isn't so much a problem in December in the Dry Valleys, nor was it a problem at Lake Untersee, because although the temperatures are often below freezing, sunlight heated my tent sufficiently during the day that the temperatures inside could be up to 20°C (70°F!).  However, in October at Lake Joyce, I couldn't get any toothpaste out of a big tube without warming the top of the tube against my stomach. There is a little secret, though: small tubes warm up faster.  Wit

Footwear, including New Boots!

Image
My new Glacier Sorel boots arrived!  With extra liners.  Plus liners for my old, less warm Sorels. They go with my skirt! The Glaciers are rated to -100°F or -73.3°C. I find the increase in the number of significant digits after a unit change amusing. Are they really rated to exactly -73.3°C? I'm sure that if it gets down to -73.4°C, my feet will get cold! I typically wear size 8 women's shoes.  However, I bought size 9 men's boots.  One of the key things I have found for foot comfort is to be able to wear a couple of pairs of socks and still have my boots loose around my feet.  That allows good blood circulation to my feet, which is essential for keeping them warm, particularly when standing around handling lines for divers under the ice.  However, I think most people would think that the boots feel way too big.  They do have good laces at the ankle, and I can tighten them down so they won't fall off.  And my feet and ankles are very strong, so I don't
