Extreme weather on Vega Island

This week’s post is about one instance of challenging weather conditions faced by the AP3 team. Written by Dr. Eric Gorscak, AP3 team member and titanosaur specialist at the Field Museum of Natural History.

One morning, Chris Torres, Steve Salisbury, Matt Lamanna, and I made the lengthy hike to Sandwich Bluff, only to find our prospecting sites to be covered in snow. The snow coverage prevented us from doing any meaningful prospecting work for the day but we had to make the trek to be sure… we only had so much time during the trip to maximize our exploration.

The weather report had informed us of an incoming front from the west that would last from the afternoon well into the night; it was already gloomy with sporadic winds during our morning trek out but nothing could prepare us for the trip back. This was when the winds really picked up, much earlier than we anticipated given the weather report. Honestly, the winds never stopped… and blowing directly at us the entire way back… on top of a 2-hour hike across harsh terrains (hills, rubble, snow, angry skuas). The winds were strong enough to hold me up as I leaned into them. If I didn’t have my beard, my face would have frozen off.

I guess you could say we walked up hills both ways in the snow and into the wind to and from Sandwich Bluff that day…

A fresh pair of socks and hot cocoa never felt so good afterward.

Normally walking by this 'pond', the water would have been quite still. As you can see, there was plenty of wave action.

Where is Kerin Claeson now?

AP3 co-PI Kerin Claeson reminisces, comparing this week of 2017 with the same week exactly one year ago, when we set off for Antarctica aboard the Nathaniel B. Palmer. 

One year plus one week ago: I was stuffing an excessive amount of long underwear and socks into my luggage. I managed to fit my Sorels and Carharts next to my rock hammer, maul, and chisels. I was equipped with enough Scopolamine to minimize my seasickness for two months straight and I guarded them like my life depended on it. My new ski mask with the built in camera was finally going to get used and i found a freeze proof, waterproof, sand proof point-and-shoot to take photos too. My GPS was charged and the maps were loaded. I packed extra hand warmers, good coffee, and chocolate. I pocketed the chapstick and hand cream my students bought me and Bob-the-Minion was tucked safely in my carryon at the request of my 3 year old nephew. The next morning, I was flying to Chile, to meet an international crew of scientists, some of whom I’d had the fortune to work with for years, others whom I’d meet for the first time. The AP3 was finally commencing, and I was ready. So much has happened since then, I can hardly believe it’s only been a year, but in truth it feels like yesterday. I’d forgotten about some of it until today, and I’m glad I stopped to remember.

One year plus six days ago: I called my credit card and phone companies from the airport to let them know I would be traveling. I called family to say goodbye and remind them to check the website for updates. I set up my away message for email which told people to write back in April after I returned from Antarctica. (I might still need to respond to some of those messages – yikes!) On the plane, I flipped through my conversational Spanish book and listened to some music. When I woke up, I’d be in South America again, so much closer to our target.

One year plus four days ago: I awoke to the phone ringing and answered in Spanish. I’m glad I recognized the voice, because I confused the caller. “Um, hello. Is Kerin in there?” said Pat. “Hi Pat, how are you?” “Good. Are you coming with us to the helicopter dunk training?” said Pat. “Yes, Abby and I set the alarm for 7. What time is it?” “7:45 – you’re late.” Abby and I brushed our teeth and got downstairs in time to grab some breakfast before hustling to the warehouses. I really wished I thought to wear layers that morning because the room we did our training in was COLD and it was the coldest I felt the entire trip.

Exactly one year ago: over the next few days we learned each other’s names, packed our sleep kits, divvied up so much candy, cereal, and hot sauce, built so many tents, and participated in a few ‘trust building’ exercises too. We sampled the local food and walked around Punta Arenas in our time off. Then the big day arrived, that’s right… the SUPERBOWL… also the day we actually moved on to the Nathaniel B. Palmer. And, exactly one year ago, I was a lone crazy soul standing on the bridge watching the plank be drawn in at 5AM. The departure was smooth and before I realized it, the NBP pushed off of the dock and we were off. Me, my Scopolamine, my AP3 colleagues and a couple dozen other people I would come to call my friends over the next six weeks.

Today: My life this week is distinctly different than the same week of last year. I have been working on a few collaborative projects on fossil fishes from Laurasia (e.g., USA, UK, and Italy) rather than Gondwana. I made plans to travel to Pittsburg to begin the next phase of the AP3. I met with my graduate student about her thesis project checking that she has more than enough data to analyze. I taught masters students about the gastrointestinal tract of humans, establishing a search image for pathology that will help them as they become allied health professionals. I met with the student president of the Wilderness Medicine Club and talked about how wilderness survival is not only for scientists in places like Antarctica, but also the homeless on the streets of Philadelphia. This week I walked those streets with my dog and we ran in the parks and played with puppies and decided to adopt one. Yes, this week has been distinctly different from the same week of last year, but just as busy and just as fulfilling.

Lab Report: “where are they now?”

This post is an update on one of the fossil specimens collected during the AP3 2016 field season. Check back again next week for more updates on 2016 results & ongoing research! 

Nearly one year after the AP3 team left Antarctica, at the end of our 2016 field season, the fossils we collected have made it back to Carnegie Museum of Natural History to be studied. Prep work on the plesiosaur shoulder girdle has begun, and our hard work at stabilizing and securing this beautiful fossil seems to be paying off!

In case you’ve forgotten: the last time most of the team saw this specimen was mid-flight, during its dramatic removal from Sandwich Bluff. We spent several days at work chiseling away the surrounding frozen rock and soil, stabilizing any crumbly bits of fossil bone with consolidant (special reversible glue), padding the surface with a layer of toilet paper and paper towels, and finally slathering the whole thing in plaster of paris and burlap. This cast would keep the shoulder girdle safe on its journey from the Antarctic Peninsula to Carnegie Museum of Natural History in Pittsburgh, Pennsylvania. Here’s the view of the jacket being lifted by helicopter from Sandwich Bluff, captured by AP3 team member Steve Salisbury:

And here’s a picture taken this week by AP3 principal investigator Matt Lamanna, in the prep lab at Carnegie Museum of Natural History. The jacket has been cut open to reveal the precious fossil cargo within:
