Ice in hand
Sea ice!

Unfortunately, shaft/cycloconverter (fancy pieces of machinery in the engine room) failures meant that science operations stopped a day early. We were forced to steam straight to Utqiagvik, Alaska (formerly Barrow) to avoid being stranded on a station in the middle of the ocean. Thankfully, this allowed us to spend that day packing up all of the equipment and get a good night’s sleep.

I’m increasingly aware of how incredibly rare it is for undergraduate students to participate in research cruises and I am even more grateful to have been given this opportunity. It is something I will cherish for a long time and I cannot wait to get back on a ship. I love doing science on boats. Despite rarely getting more than four hours of sleep at a time, being cloaked in endless fog, and missing three of the nicest weeks of the summer in Victoria, it was so worth it for this incredible experience of lifetime. The number of times I found myself BEAMING all alone, basking in how happy I felt, was a little ridiculous.

Laurier CTD

All of the tough things about being at sea made the positive things that much more welcome. A day of sun, a whale sighting, making connections with people from all walks of life, pensive life chats at 04:30 staring into the still-lit horizon, dancing to Motown hits while sampling from the rosette, hot tub soaks sailing past the Aleutians, gaining practical skills and knowledge associated with jobs I want to pursue, the best chocolate cake I’ve ever had, getting to see sea ice in person, collecting rocks from the bottom of the Chukchi (yes, I have been told that getting excited about this makes me a nerd), and even the daunting/rigorous arctic crossing ceremony (this shellback is no longer a lowly tadpole!!) – all of these things outweighed the trying times by far.

Final tally of wildlife seen:

  • >3 pods of grey whales in various locations
  • We almost hit a grey whale but the Captain saw it in time and Andre-Ann steered away perfectly!
  • Breaching grey whale
  • Countless bald eagles and a humpback whale coming into Dutch Harbor (seen from the hot tub)
  • Many puffins, parasitic jaegers, gliders, fancy arctic ducks
  • >4 albatross
  • Lots of benthic organisms pulled up from the ocean floor during Van Veen mud grabs
  • One adorable baby seal – the size of a loaf of bread!! It swam right up to the ship while we were on a station!

It was too foggy on our last day on the ship to helicopter off so we took our final glances of the CCGS Sir Wilfred Laurier from the “safety” of a Zodiac. I don’t think this is the last time the Laurier and I will cross paths.

Friday the 13th was the Luckiest Day Ever

Bering Sea
The Bering Sea

I am incredibly sleepy. We have now crossed into the Bering Sea after stopping in Dutch Harbour to pick up the American scientists. Leading up to Friday, July 13, I knew I had to finish taking 38 samples from the underway loop running through the ship, saving five samples for after Dutch Harbor. I had not had longer than two consecutive hours of sleep for the previous five days. I worked hard to finish off the last samples before finally having a bit of relaxation time with Gina and Shea. We hung out on the upper decks and the bridge, where we spotted loads of seabirds (puffins and albatross were the coolest) and tons of whales (orcas, greys, and humpbacks). The light was beautiful! Approaching the Aleutians, we hopped in the hot tub to watch the gorgeous scenery pass by. It was an amazing evening.

Hiking Dutch
Gina and Sarah hiking along the ridge in Dutch Harbor.

In Dutch, we made the most of being on land by going on one of the most stunning hikes I’ve ever had the pleasure of hiking followed by going to the Norwegian Rat bar in town.

The next two days were filled with preparing for the beginning of stations, helping the American scientists set up their lab space, and the Shellbacks (those science and crew members who have crossed the Arctic Circle by sea before) explaining some of the upcoming tasks for us Tadpoles (those science and crew members who have NOT crossed the Arctic Circle by sea before) to partake in. I’m pretty sure I’m not allowed to tell you any details, but the tasks have certainly consumed some of our time and energy.

I finally experienced seasickness. I had begun to think that I was just going to escape it altogether but after five days of spending hours on end focusing on filling resin columns, taping them carefully, moving around, and lifting heavy water samples in the lab with very few windows, all while the ship tilts back-and-forth to some pretty wild extremes finally got to me after all. Sorry to be graphic, but I threw up once, felt immediately better than I had all day, but not good enough to eat until over 24 hours later. I have been taking naps whenever possible and drinking lots of water, both of which have been helping immensely. I still don’t sleep more than two hours at a time, but my samples have been running much more smoothly now (thanks to Magic Wrap), so that is a bonus.

As I spend more time with the crew, I’m finding every single person to be so kind and enjoyable to be around. The crew on the bridge now know that I want to be informed whenever they see whales and it has already paid off! As we were deploying an underway CTD [a reusable instrument to determine ocean temperature and salinity] off the aft deck, a pod of sperm whales was out on the starboard side of the ship.

Everyone is also curious about the projects that I’m working on. I love getting to tell them and ask them about their lives and their rolls on the ship as well. It seems like quite the crazy life they all lead. Most of the time, they work four weeks on, and four weeks off, but the Arctic voyage is six weeks on, and six weeks off. My favourite question to ask is what everyone likes to do in their time off because the answers are all so unique – from scuba diving and foraging for mushrooms to pottery and horseback-riding, everyone has a cool hobby to entertain them in their long stretches of time off.

Laurier fjordShea and I tended to the incubations on the helicopter deck for a couple hours this afternoon. I am stoked to be gaining skills in his line of work. The rest of the time, I was running my own samples, or sleeping with one break for dinner (feeling good enough to eat 😊 ).

Today marked the beginning of the on-board bingo craze. Nearly every person on the ship participates, they announce ~15 numbers per day just after lunch and each round, they go for a different shape (horizontal or vertical lines, wine glass, cactus, blackout, etc). The prizes are quite extravagant – there’s an expensive coffee-maker, high end scotch, and camping equipment – just to name a few!

Tonight is another movie night with unlimited popcorn. We are watching a film called ‘Annihilation’. I am mostly going to attend for the popcorn and the extra-strong G&T’s.

Not too much else to report here! I’m still having a wonderful time at sea regardless of feeling ill and not getting much sleep.

Fueled for Exploration

WWII plane-1
The RAF Dakota 576 crash site just outside of Port Hardy.

Yesterday I awoke in Port Hardy and was told we would be spending the day docked while the ship refueled. This meant that 13 hours was needed to top up the measly one-million-liter diesel tank beneath us. This also meant that the crew and supernumeraries (aka the scientists) were allowed to disembark and explore Port Hardy. My roommate, Gina, and I went for a hike, recommended by a local, to the site of a WWII plane crash. The hike was through a lush, muddy, and mosquito-ridden rain forest and it felt amazing to stretch our legs and smell some trees. Gina, a Vancouver Island native, told me which berries were safe to eat along the way and I tried salmon berries for the first time! Seemed like a genetically-modified cross between raspberries and oranges to me, but they were very tasty.

After returning from our hike, Shea and I left again to visit the hardware store to replenish some supplies we were both short on. In an attempt to solve my leaky column problem, I bought ten more rolls of electrical tape, and something called “Magic Wrap” which claimed to form a rubber casing around a cylinder and stay water-tight. I have now tried it out with the next seven samples and it seems to be working – THANK GOODNESS.

We then returned to the ship to assemble Shea’s incubator on the helicopter pad. His experiments are looking at the effect of increasing atmospheric carbon dioxide levels on phytoplankton growth. We bubble air with present-day atmospheric constituent concentrations (CO~ 410 ppm) and air with one of the projected constituent concentrations for the year 2100 (CO~ 750 ppm) into separate containers holding the same diversity of phytoplankton and we will soon see how the organisms react to increased levels of the greenhouse gas.

We still had a couple more hours to kill so I went for one last jog on land among the pretty rock faces and lush wildflowers along the highway. As we ate dinner, the ship started to move again which indicated it was time for me to get to work. I processed a few samples over the course of the night, waking every hour to check for leakage and to change out fresh carboys.

ARGO float deployment-1
Preparing the ARGO float for deployment.

I am getting more and more confident with the lab protocols, remembering the crew members’ names, and navigating routes around the ship. I am constantly in awe of the stunning scenery surrounding us. Watching the waves interact, the sky change colours at dawn and dusk, and keeping an eye out for whales doesn’t cease to entertain me. I remain endlessly grateful for the chance to fulfill one of my dreams and take this trip of a lifetime.

Speaking of dream come true, I am about to go take another sample, watch the deployment of an ARGO float, eat a strawberry tarte, and then watch the sunset from the hot tub. Goodnight!

Bitter-sweet Bon Voyage

6 July 2018
Seeing an aerial photo of the CCGS Sir Wilfred Laurier and reading a blurb about an undergraduate studying chemical oceanography on the university’s homepage was the tipping point that helped me decide to attend UVic for my post-secondary education.
Like most students in grade 12, I had very few ideas of what I actually wanted to do with my life and career, but seeing what the possibilities were inspired me and I promptly enrolled in the Earth and Ocean Science program. Becoming that undergraduate who has the privilege to do scientific research on a cruise seemed like an unrealistic dream – unachievable for an average student like myself. But lo and behold, a little over three and a half years later, I somehow fooled the people in charge to let me participate!
After two months of working on the InFORM project in the lab, the cruise idea seems a bit more normal to me, but I am lucky to be constantly reminded of how much of a privilege this voyage is. Friends and coworkers all have similar humbling reactions when I mention what my summer job is and what part of the world I get to explore – “Wow, that is so cool! Take me with you??” My dad marveled at how I might be the only person in our family who will have crossed the Arctic Circle (before I reminded him that his own father is from Finland). My mom declared that I might be the coolest person she knows because I get to sail with the coast guard. (Sorry to my sister Marina. If you’re reading this, it’s official – I’m cooler than you. Mom said so!!)
Everyone in the EOS department has been so incredibly helpful in preparing me for my trip, especially Dr. Jay Cullen, Sue Velazquez, and Annaliese Meyer. They’ve helped me understand the procedures, both in our UVic lab, with the citizen science samples, and in providing insights to what my life will look like on the ship. From lab techniques to prevent samples from leaking, to the best seasickness meds to have on-hand, to preparing to eat my body weight in decadent fresh-baked pastries; I feel quite ready for what is to come.
Getting ready for departure!

I have stepped foot on the CCGS Sir Wilfred Laurier three times in the past few weeks. First, to set up the lab equipment with Jay. Second to give my mom and stepdad a tour of where I will be working and living for the next three weeks. Last, to bring my personal belongings to my room. It is a lot more spacious than I was expecting. I found out I will only have a roommate for about half of the time (I thought I would be sharing a room the whole time), and it has a little porthole (I had pictured I would be getting one of the interior, lightless rooms)! So overall, I’m already pleasantly surprised by the experience.

After we set sail tonight at 18:30, we will be having a full tour of the ship and a safety briefing. This will be followed by our first meal as a team. Then we get to work.
The route of the annual CCGS Laurier trip from Victoria, BC to Barrow, AK.

My project involves collecting seawater from what is called the loop sampler. This water runs through the ship  and gives us an accurate representation of the ocean conditions. The seawater is run through a resin which binds to the radiocesium in the water that is left over from the meltdowns of the Fukushima Daiichi nuclear power plants in 2011. Once all of the cesium is bound to the resin, I will send the resin to Dr. John Smith‘s lab at DFO’s Bedford Institute of Oceanography where they use gamma spectroscopy to determine how much cesium is at each sample location. These data will become part of the timeseries from the previous undergrads who have taken the same NE Pacific/Arctic cruise to see how the amounts of cesium have changed through time.

Well, all of my lab equipment is set up on board, I have a seasickness-halting medicated patch behind my ear, and I’m about to walk back to the Laurier‘s temporary resting place at Ogden Point where my feet will soon leave solid ground for the last time. I truly wasn’t sure if I would see this day, but here it is, and I’m ready (as I’ll ever be) to set sail!
