Back home! Science Advocacy

Connecting with a rock.
Goodbye to the Taylor Valley! I'm back in Ohio. This time, returning from the field feels shocking. The U.S. just shut its doors to immigrants from 7 countries and plans to ramp up fossil fuel extraction. Our entrenchment in carbon-burning grows and yet, last year was the first year that green energy jobs surpassed fossil fuels. Some of the worse impacts of climate change have already been felt in places like Syria.  But climate change impacts life in Ohio too.  My children can't swim in our local reservoir during the late summer when microcystin takes hold in increasingly warm waters. Clean water is central to our economy (recreation, fisheries), but we're fighting a losing battle if we let surface waters continue to warm.  
Students exploring wetland and stream conditions & chemistry
This semester, I'm completely revamping my courses to include evidence-based political advocacy. My global climate change classes will examine climate data and consensus reports and come to their own conclusions on the realities of climate change. An emphasis on problem-solving is key to those planning our climate resilience. So my students will consult with local partners who plan for the consequences of climate change in their work. This includes watershed managers, city stormwater managers, and businesses who seek solutions that are profitable and improve our health. After working with experts student teams will advocate for relevant policies based on the evidence they have examined and partner and personal interests. Along the way, I am already rethinking how I teach students about information sources.  It is not enough to have my students explore peer-reviewed literature. They need information on how to evaluate the sources they are actually reading. This teaching module on logical fallacies helps. It is pretty easy to get caught in a loop either on the far-right or far-left where our own ideas are confirmed.

Some key things to reinforce in class:  1) evaluate information critically 2) diversity and openness matter now more than ever. It is time to vocally counteract an image of evil brown people and instead think about removing barriers for people who have the greatest biases against them.

More than ever we need to work across disciplines to combat alternative facts and solve the challenges facing humanity.

Glacier in the Dry Valleys

The surface of the Commonwealth Glacier, some places had so much snow, we wanted skis.
One of the smaller cliff faces (just double my height), along the Suess Glacier

Several glaciers have steep areas & icefalls.  Channels are more obvious lower.

Glaciers the Dry Valleys

Arms burly wind
Awakened, flapping, punching
Crushing basalt, granite, dolerite

Legs giant monuments of ice 
Monstrous ledges, anchored rocks, and hardened streams
Brilliant entrails revealed by ablation
Bandaged by snow

If you too were a glacier
You would howl and be still
You would hold time and secrets
Frozen sinew, stronger than skin and warmth

A day trip to the Howard Glacier

Spent yesterday sampling the Howard Glacier with Renee, a camp manager at Lake Hoare. She has a generous spirit and has made science in the valleys easy.  It was a fantastic day for a helicopter ride and a sampling trip, but we had to hike completely off of the glacier to find water running from the terminus. We both not-so-secretly wished that our ride would not come back and that we would have to hike 10 miles back to camp. There is something about this place that merits walking long distances. It is hard to place. 

Antartica's explorers are
the carpenters and the cooks
the poets and the pilots
the mountaineers and the mechanics
the scientists and the shuttle drivers
Snowblindness, crampons, pitons
filtering, acidifying, analyzing
choreography, chromatography, chamelography
far, far away, in a magical place
a conjuring, a voyage
that is now, but that won't fade

Renee & I were dropped off on the Howard Glacier near a met station.
 No water was flowing in these channels after a few cloudy days

Pretty breezy up on the Howard, but removed most of my layers lower on the glacier.

Renee is looking past the Howard Glacier back toward the Suess.

Solo Mission

We've had some clouds. This has slowed down my search for water on and flowing off of glaciers. Yesterday was partly cloudy and promising so I set out to sample the LaCroix Glacier.  A 15 mile round trip... I only walk like this for science. 

My plan was to approach the Suess Glacier and to keep walking past it up valley if there was any melt.  If one glacier is melting, why not the next? The daily rhythm of glacier melt depends on the circling of the sun, altitude, and the presence of warming soil and rock. I set out knowing my mission might be a failure.  But, I also wanted to visit Mummy Pond and retrace my 2001 steps around the north shore.  This was a lesson in climate change. The pond formerly known as mummy...  Many of the seals I saw more than 15 years ago were completely submerged by the rising lake. No longer photogenic.

While the mummies of my memories are gone, I did get a picture of another mummy near the Suess Glacier.  I feel bad because my kids always ask me about the animals I see. Here in the valleys, there is a lot of life if you look closely, or use a microscope.  But larger mammals like seals and penguins have traveled the wrong direction from the sea only to die near the false seas (lakes) in this dried up valley.

My LaCroix Glacier water hunt was narrowly a success. I grabbed water just as the glacier was shutting down as the sun moved behind the Asgaard Range. I'm eating homemade biscotti today & stretching.

A mummified seal on my way to & around the Suess Glacier.

Taking pictures for the kids.  Rose, the unicorn, tends to eat all of my Snickers.

Water flowing near and on the Suess Glacier means this hike is not over.

I always feel like a geologist in this environment.  Sediment transport.

The Suess Glacier has sediment piles over much of the terminus (end).

Walking around the Suess, the melt features change. 

I reached the LaCroix around 3 p.m. & sampled.  The water was shutting down as the sun went behind the Asgard Range.  I had to work fast.
Now I have to walk back.  Home by 9 p.m.

New Year's Eve

Lake Hoare Camp, overcast weather doesn't look good for water sampling...
There are only people in camp.  Rae, Kathy, & I will enjoy a quiet day.  I'm pressing my coffee & considering a 10 mile hike to the LaCroix Glacier to see if any water is flowing off of it (& not just in the stream below).  But, it has been fairly overcast a few days & the last glacier surface water missions required that I step onto the glacier & swing a mallet wrapped in plastic at the ice-lidded melt holes & channels.  Hiking with a chance of whack-a-mole.  Because success is unlikely, I'm considering some other options & I'm taking mascots from my son & daughter's school on a hike to take pictures as the landscape changes.  I have 4 polar bears from Snowhill Elementary second grade classrooms & one unicorn from Covenant Children's Academy kindergarten.  They  have been anxious to get out, but would likely blow away during sampling... but today I will be down in the valley much more than up high.  So we are going on an adventure after I press some much needed coffee.  Two cups & I'm off!

Three people today, so many more for Christmas.  But it was fun!

Plan A, Plan B, Plan C. (aka walking a lot for science)

Yesterday's science adventures on the Commonwealth Glacier. Pete, a mountaineer, and I took a long hike to find water on the glacier surface and then we had a helicopter flight to sample the Taylor Glacier today.  Success!  These samples will be analyzed for trace element concentrations, major ions, & hydrogen & oxygen isotopes in a few months. What are the chemical conditions supporting life on the top of glacier surfaces & what are the chemical contributions of glaciers to the downstream ecosystems?
The beginning of a 14 mile sampling journey.  Crossing Lake Hoare.
Pete pointed out a route across the lake, we avoided an open moat.

We walked around the terminus to get to the other side of Canada Glacier.

 Best ATV tour ever! And we crossed another lake. Thanks Christa!

Pete I hiked up for a few hours before we could get onto the Commonwealth.

We found water, I sampled!  It took 14 hours to complete this mission.

After camping on Lake Fryxell we took a helicopter to the Taylor Glacier :waster!

A hypothesis

Are you answering a question?
Magnetic pulling, landscape suctioning, visioning
What is necessary and what is possible and what is muscular are woven
This is a journey

Weather Delay

My tent.  The temperature varies and requires a sequence of clothing layers throughout the night.  It is always technicolor yellow inside.

"Word/mist, word/mist: thus it was with me.  And yet my silence was never total-" L. Gluck.

These pictures are of the Canada Glacier, this week I have been sleeping next to it and taking samples of cryoconite holes (melt that forms around sediment and seals with and icy lid) and streams on the surface.  Water chemistry holds clues the ingredients needed to support life on the glacier and downstream.

Back in the Valley

Ventifact on the Nussbaum Reigel, Taylor Valley, Antarctica

A rock whittled by the wind to climb into.
Wild places.  Blogging to share. It has been 9 years since my last visited to Taylor Valley, Antarctica.  The lakes are rising in response to climate change. Our footsteps along the lake shores erased. The granite still whittling away, the seal bodies still mummifying, the sky still parching rock and skin. My legs can still keep moving miles & miles until the water from glaciers fills my bottles. Their surfaces so strangely beautiful and other-worldly that I wonder if I've gathered Martian tears. And in 24 hours of daylight all things are possible, even a traverse of the Suess Glacier that ends at 10 p.m., or a sneaked peak outside of your tent in the middle of the searingly bright night. Some places stick inside of your memory- always  vivid. Endurance is not just motion.

Pictures from our 87 degree-day April sampling

Annette & I took some pictures from our recent cornfield endeavors.  (Thanks for bringing your camera Annette!)
Me waiting for the Licor to take a soil respiration measurement from a no-till corn field prior to planting.
Me taking a groundwater percolation sample from the large, in-ground, lysimeter in Coshocton, Ohio.  

Surface water runoff from the mixed landuse site.  The water is cloudy because the weir was recently dredged to remove sediment from the water-chemistry auto-sampler.

The microbial underworld, undergraduates, and exciting implications

It has been a while since I've blogged.  I've been sciencing away

Also, Carla and Michael, the two undergrads working with me, have been working up their data on agricultural land alkalinity and tropical glacier silicate weathering, respectively for posters coming up this week and in May!  Nice Work!  

And I have some new very, very, very, very exciting data from the cornfields that has some implications for the affects of landuse on the carbon cycle.  I am dying to bust it out here, but I haven't seen anything similar published to date, so for the moment, I'm like a kid waiting for the tooth fairy... jumping up and down in my seat. I hope I'm not leaking.

And it is back to the cornfields on Monday.  It will be as pictured below, the weather is supposed to be summeresque.

Cornfields & Polar Days

Last week was a big week!  I went to the fields and sampled storm runoff from till and no-till plots as well as the forested and mixed landuse sites. It was a rare solo trip because we're approaching the busy season near the end of the quarter at OSU and the undergraduates all have exams to study for and reports to turn in.  The cornfields were far muddier than the forested sites and I suspect filtering those samples might take a while. I had a fun time getting the truck up one of the valleys and stayed in 4wd most of the day. From Friday's storm it is evident that much carbon is lost from plowed landscapes..., but I really have no idea what to expect in terms of soil respiration.  It doesn't seem that much could be living and breathing in the cornfield or even the other plots right now.  Temperatures have dropped from 50 F to 10 F today and won't be much warmer tomorrow.  Carla and I will head back to the fields tomorrow to hook the Licor up at our plots and see what baseline respiration is...pretty soon those plots will move from near flatline to robust exhaling. 

At any rate, on Saturday I went to COSI the Columbus Center of Science and Industry with Rachel Hinz and we led a group of 30 8th grade girls in flubber explorations.  They modeled glacier flow. Flubber is a mesmerizing glue substance that flows viscously and  shares some properties with glaciers... although as the girls noticed, flubber doe not melt.  After this, I flew down the stairs to give a brief slide show of Antarctic travels to a group of 3 to 50 year olds... my slide show followed an explosion set off to draw listeners in... I have to say COSI knows how to draw a crowd.  I may have to begin all my talks with a loud clang and some smoke.

Hobbies other than science?

The snow blazes down and fizzles out on our Ohio pavement and fieldwork feels distant. During this season, my poor schnauzer is skittish on the ice and our walks grow shorter. As gray blankets us, I miss the aesthetic aspects of being in the field. And when not working, I find myself reading dark literature until I get into a funk and become one with my couch.

And now, I'm attempting new hobbies; pretty and far away from writing manuscripts or proposalling. Today, I officially enrolled in an evening watercolor class at the Columbus Arts Council. This blog is primarily focused on science capades, but the awescapes I've been fortunate to visit trigger a gut need to do something artistic. For the rest of the winter, I shall stay away from sad literature. That being said, if you want a good couch cry read "The Blinding Absence of Light". It's even sadder than "Blindness" and "The Road".
