South Pole: At Last

By Lindsay Berkhout (University of Chicago Astronomy and Astrophysics Undergraduate)
Pole day 1
The morning of our last day in McMurdo we decided to venture out again in search of wildlife, and this time were rewarded as we headed to the Observation Hill trail. We could see some open water, and movement in the water, as well as some black dots on the edge of the ice. As we came closer we realized we were watching two whales circling two penguins on the ice. We sat and watched in awe until the penguins slipped back into the water (fortunately, none of them were eaten on our watch).

Later in the afternoon, we hopped back onto “Ivan” the Terra Bus, and were on our flight to the pole! After a 3 hour flight on the LC-130 with some mixed knitting, reading, and napping, we arrived at the station around 8:00 p.m. Martin, one of the IceCube collaborators at the station, greeted us before our briefing and showed us around so we could get our bearings. The last item of the day, of course, was pictures. We headed out for our first trip into the cold to visit the geographical and ceremonial south poles, as well as the welcome sign for Amundsen-Scott South Pole station, and took in the vast ice around us.

Pole day 2
The morning after we arrived, we got an early start to work. We started the day by meeting with Rob, the winter-over assigned a few ours a week on the neutron monitors, and performing a chip swap on the indoor rack for the neutron monitors. We were tasked with removing the current chip on the master board for the third neutron monitor on the platform, which was swapped a few weeks beforehand, and putting the original chip back in.

Then, we headed out to the platform to swap the remote chip that was inside of the neutron monitor, and get a good look inside the monitors for the first time.
The neutron monitor remotes are on a platform between the South Pole station and the clean air sector. They are proportional counters that respond to neutrons produced in cosmic ray interactions in the atmosphere.
Now, we just had to wait for the remote collaborators to check the data and let us know how it looked. After lunch, we spent the afternoon doing some inventory on the current neutron monitor supplies, which mostly consisted of checking the spare heaters to make sure that they were working. We then spent the evening relaxing and experiencing the station life.

Pole day 3
Our morning consisted of doing the heater checks out on the neutron monitor platform, so we geared up and walked out again. We brought our some of our spares that we had checked the day before, but thankfully none of the heaters had failed, so we brought our spares back to the lab in the station.
Martin Rongen (IceCube, Aachen Group) helps with closing up a remote after testing the heaters. Three IceCubers came out to see the neutron monitors while we were testing the heaters.
Then, after some lunch, we took a walk out to the IceCube lab to check out the server room and pack up the old IceAct lens that had been removed, which will be used for a student project at River Falls next summer.
Suruj Seunarine inspects the old IceAct lens. We packed it for sending north and it will be used for an REU project in summer 2018.
We also got some great views of the Keck, South Pole Telescope, and BICEP experiments (see featured photo), as well as a look over where the IceCube detector is buried. It was incredible to see the span of the detector that I had spent the summer working on, and the large scale science experiments that are going on at the pole. In the afternoon, I got the opportunity to launch a small meteorology balloon, used to measure how high the cloud ceiling sits. After letting go of the balloon, it is timed to see how long it takes before we can no longer see it, and the cloud height can be extrapolated from this.

For the rest of our afternoon, we spent our time in the B2 lab with some of the IceCube collaborators, hanging out and getting some work done. Here are some more photos from the first days at the South Pole.

On The Ice, At Last!

By Lindsay Berkhout (University of Chicago Astronomy and Astrophyics Major)

1/26/18

On the LC-130 flight to McMurdo Station.

Per the usual drill, we woke up for a 5:45 AM shuttle to the CDC, hoping today would be the day we flew. We were bumped off our 9:00 am flight, but given seats on the next flight out at 2:00 pm. After an anxious few hours of waiting, we went through security and were finally on a plane to McMurdo! We flew for around 8 hours on the LC-130 plane.  After about five hours blocks of ice could be seen floating in the sea, after about six hours ice flows and icebergs appeared.

After about five hours flying south, icebergs appeared in the sea.

And short while after we were over the Antarctic continent.

Approaching the continent of Antarctica.

During the flight some of us were invited to the flight deck. We landed and loaded up onto “Ivan” the Terra Bus for a half hour ride into town. We were dropped off at the Chalet for an in-brief and then we collected our checked bags at midnight. Then I promptly turned in for the night after a long day of flying.

1/27/18

The next morning we woke up for a meeting and tour of the Crary Lab, where most of the science offices are housed. In the afternoon, we took a walk down to Hut Point Peninsula, to have a look at Discovery Hut.

Discovery Hut, built by Robert Scott’s expedition in 1902.

The hut was build by Scott in 1902, during the Discovery mission, and was used for shelter on a few later missions. We couldn’t go inside, but we got a good view of the items left outside, including a seal carcass that was still there after all the years, and got a look through the windows. Because a shipping vessel was docked in town, we had to take the long way to the hut, so on our way we searched for some wildlife.

Our search for penguins was in vain, but we did see some skua and skua chicks. Skua are large, aggressive brown birds, and under protection from the Antarctic treaty, you cannot disturb them in any way (even if they disturb you). This happened to us on our walk as 3 different skua managed to block all our paths down to the hut, and we had to try to creep quietly past without disturbing them. We also saw a few seals, one in the far off distance sleeping, and briefly one in the water near Hut Point.

Today was our last scheduled day in McMurdo, so after a good night’s rest and some breakfast, we decided to summit Observation Hill.

Observation Hill, our destination for today. Volcanic rocks and sand are everywhere around the station.

After a hike up the rocks, we were privy to incredible views over McMurdo and the ice shelf, as well as a look at Mt. Discovery and Mt. Erebus.

In the afternoon, we took a shuttle over to Scott Base, the Kiwi Antarctic station a few minutes from McMurdo. We spent some time walking around the store there and admiring the seals sleeping on the ice all around Scott Base. 

 

Still Here: Christchurch and Arthur’s Pass

Christchurch day 7

After an early morning ride to the airport, we were informed that we had been bumped from our flight, and headed back to the hotel. After a quick lunch, I made

Kea,, a native New Zealand bird.

my way to the Willowbank Wildlife reserve on the outskirts of Christchurch. The reserve housed many native species to New Zealand, including the famous Kiwi bird, Kea, Tuatara, and a very friendly wallaby.

 

 

 

Day 8

Another delay and another day in New Zealand, so I made my way out to the port town of Lyttelton. After a delicious seafood lunch, I rode the gondola up to the hills that split Lyttelton from Christchurch, and took a walk back down. The ‘Crater Rim Walkway’ offered beautiful views over both Lyttelton and the Canterbury plains.

Day 9

Today, we hired a car and took a drive to Arthur’s Pass, a National park nestled in the Southern Alps. After a scenic mountain drive and some lunch, we took a short hike to the ‘Devil’s Punchbowl’, a spectacular waterfall coming from one of the peaks.

Christchurch day 3

Our flight to McMurdo was scheduled for 4 p.m, so around 12:45 we got on a shuttle to the airport and packed our things. However, upon arrival, we found out our flight was delayed for 2 hours and then cancelled, so we gathered our boomerang bangs and headed back to the hotel, with our flight rescheduled to 2 days later.

This is as far as we got in the past few days.

I enjoyed the rest of the evening in and then went out for some Thai food on New Regent street.

Christchurch day 4 

We had the day off as there are no flights scheduled out on Saturday, so we took a bus out to  Sumner and enjoyed the nice weather by taking a walk down the beach. I settled down to read for a bit (and sunburnt myself!), and took a little walk around town after heading back. Then, we went out to meet up with some friends of Suruj’s for dinner and a cup of tea.

Christchurch day 5 

We woke up to a message telling us our flight was delayed, then cancelled- so I set out to do some more exploring. I was able to take a full tour of the botanic gardens, including the conservatory and the New Zealand gardens, as well as enjoy the local art gallery (and some gelato!) 

Botanic Gardens.

Christchurch day 6

With a morning delay, another delay, a cancellation, and a rescheduling of our flight, we headed to the airport once again, only to be met with another cancellation upon arrival. We returned to our hotel and enjoyed a day off before we try again tomorrow. Meanwhile the city is buzzing with the International Busksers Festival in full swing with street performers showing up many street corners.

Exploring Christchurch

By Lindsay Berkhout (University of Chicago Astronomy and Astrophyics Major)

We started off our second day in New Zealand by travelling to the CDC to receive our cold weather gear and receive the safety briefings. Depending on the weather, our flight to McMurdo station was scheduled for the next day, so we spent the morning preparing our gear for the flight.

Then, it was off to the University of Canterbury to meet some of the IceCube collaborators who work there. The university was fairly empty due to their summer break, but the collaborators were still hard at work, and I got to take a beautiful walk around the campus in the 80 degree weather.

After that, we headed back towards our hotel where we split up and I took a walk around downtown, stopping into “Rutherford’s Den” at the old University of Canterbury buildings, where Ernest Rutherford spent his early university days.

The old University of Canterbury campus in downtown Christchurch. After the university moved the suburbs the old campus became the city’s arts center.

Most of it was blocked off for a Buskers festival, but it was still cool to walk around the buildings (and, of course, the gift shop was open). Then, it was a quick stop at the Canterbury museum before heading for a walk around the botanic gardens to look at some of the native (and non-native) New Zealand flora.

Christchurch New Zealand, 2018

By Suruj Seunarine, Associate Professor of Physics ,UWRF

Today we arrived in Christchurch, New Zealand, the first stop on the way to Antarctica. Lindsay Berkhout (U. Chicago undergraduate) is deploying as well this year. Lindsay was a student in our 2017 REU group at UWRF.  We got to Christchurch after a thirteen hour flight from San Francisco to Auckland and then a short one hour flight to Christchurch.

Lindsay at the Re:Start container mall. The container mall was built to give businesses a chance to get going again after the earthquakes.

This is a homecoming for me, I lived in Christchurch for about nine years and left just before the big earthquakes hit. Everywhere there are wide open lots where buildings used to be. But there a many new buildings too and though most of my favourite restaurants are no longer around it was still easy to find something to eat. And there’s art and sculpture everywhere.

The cathedral at the heart of the city still needs a bit of work. But all around  it there are signs of the rebuild of the city.

Tomorrow we go to the CDC to get our extreme cold weather clothing and to have our laptops checked. On Friday, if the weather is good, we will fly out to McMurdo Station in Antarctica.

Today, June 5th, was the first day of the 2017 Ice Cube Boot Camp here in Madison, WI. We made our departure from River Falls campus mid-day on Sunday, June 4th, and drove straight through (aside from a quick stop at Culvers). We arrived here in Madison around mid-afternoon. This is only my third time here in Madison and for many of the students in our group, it is a first. The weather yesterday was warm and sunny, which only heightened our ever-growing excitement/curiosity in our unfamiliar surroundings. Everyone unloaded and checked into the dorms quickly, then immediately set out to tour the beautiful campus. Dylan and I began our journey on the trail that encompasses the lake directly behind our dorms, and eventually moseying our way down to State Street. There we spent the remainder of the afternoon popping in and out of interesting shops and finished it off at one of the local sports bars where we ate some delicious food and enjoyed the basketball game.

This morning I woke up bright and early with an overwhelming sense of anticipation for the day ahead of me. Prior to arriving I spoke with some of my peers who attended the boot camp, but I was still unsure of what to expect. I made my way over to the WIPAC building with a group of students from Marquette. Walking into the building we were greeted by students and faculty who appeared equally animated for the day. Boot camp began promptly at 9 am with a brief introduction to Ice Cube, followed by a more in-depth overview by Francis Halzen (AKA Neutrino Man). The way that Francis spoke sparked the room with an undeniable feeling of awe and inspiration.

We spent the next hour covering the principles of astrophysical and atmospheric neutrinos that Ice Cube was built upon. We then took a short coffee break and jumped right into working with the Ice Tray framework. Things moved along quickly and within a few short hours we covered everything from viewing simulations of neutrino events and reading data with python. For lunch, some of the group opted to walk around the Capitol building with Dr. Seunarine. In the meantime, I was able to sniff my way to an adjacent street with a handful of food trucks positioned along the sidewalk.

The day was concluded with a talk from Prof. Williams giving us a detailed introduction to the calibration LED ‘flashers’ that are on each IceCube DOM. Her presentation accentuated the unbelievable amount of thought and purpose that went into the construction of the Ice Cube detector. She went into detail about how the flashers are used to test the calibration and response of the DOMs. Moreover, the flashers are even used to study the optical properties of the ice itself. Several summer interns will work with the so-called ‘flasher’ data in their projects.

After making the trip back to campus to drop off our bags we made our way over to the terrace on the lake to unwind with our fellow boot campers after a long day. On our trek back to the dorms we even managed to catch an immaculate display of the sun setting over Lake Mendota. Needless to say, I am excited to soak up as much information as I can throughout the upcoming week and make some new connections along the way.
