Exploring Reykjavik

Hello Everyone!

I'm joining Dr. Welter in Iceland this summer because I have been interested in ecology for the last few years and really wanted to explore that interest further. I'm excited to be starting a new project here and to see where that goes! We will be heading up to Myvatn to measure nitrogen fixation and metabolism in the lake, as well as the surrounding rivers. 

A street in Downtown Reykjavik 

On our first day here, we went straight to our apartment and got settled in. After resting for a few hours, Gabby and I made our first outing into the streets of Reykjavik and to visit Bonus, a local grocery chain. We hit a bit of a rough spot here trying to differentiate between real butter and fake butter. We figured it out though and managed to walk out with real butter! This excursion was followed by some more rest (we were exhausted from the flight). When we woke up, we went to explore the shops in downtown Reykjavik and to walk along the water.

Reykjavik Coastline

While exploring, we found a building without a sign that looked incredibly interesting. The building was partially hidden behind a hill and some trees and had no visible signs. As we walked closer, we noticed the interesting layout of the building. There appeared to be a courtyard in the middle of the building surrounded by windows. We went inside the building and were greeted by a very friendly security guard who told us that we were in the National Bank of Iceland. He let us through the doors and we had the opportunity to look at the full history of Icelandic currency. We were unable to go out in the courtyard for security reasons. The exhibit included many objects that used to be exchanged as a form of currency to cash and coins and even some of the most recent credit cards that have issued in Iceland. 

After visiting the National Bank, we wandered around the downtown area until we found a very famous and popular hot dog stand that Gabby wanted to try. I don’t know if it was the jet lag or all the walking it took to find it, but the hot dogs were incredible! The mustard on the hot dog was amazing and unlike any mustard I have ever tasted. 

The speed of life here is slower than it is back home and I have really enjoyed that. The city feels incredibly safe and I like the active lifestyle that is important here. I'm looking forward to our adventures in Myvatn!

What makes a data point?

As a student, especially in the sciences, I've spent hours reading scientific papers. Each paper is composed of an abstract, introduction, methods, results, and discussion. One thing I've learned over the years is that figures have the power to provide resolute understanding or utter confusion. Yet each paper that is published and each figure that resides within it is meticulously designed and revised. Regardless of who reads the paper, the audience should be able to gleam a big picture view of the results. That's the beauty of a figure. It's able to convert chaotic datasets full of numbers into elegant and informative visuals.

Figures are meant to be clean, simple, precise, and minimalist. However, readers often forget to acknowledge the hundreds of hours required to produce that single figure. A figure is not just created, it is a culmination of intense work. At the end of this summer when we start analyzing our samples and datasets, it will be satisfying to see all our efforts displayed as a figure. But, it will be just as astonishing that all our work can and will be portrayed in a few figures. Each data point will be the product of a team of people who dedicated hours to acquire that single number.

For example, when determining nitrogen fixation rates we need to travel to Hengill, carry our field gear to the sampling site, set up our incubations, collect and preserve our samples, analyze our samples, process the data, and finally produce a figure. Each of these steps requires lots of time and effort, all for a single data point. Now multiply that work load by adding other components of the core project as well as other side projects and the to do list becomes endless. As we work day in and day out and continue to push on every day it reminds me to applaud the scientists before me and truly appreciate what they have done. 

We are relentless workers. Our work hours are not bound by 9 to 5, 40 hour weeks, but rather by how long our bodies are capable of persisting. Although we may want to yell into the sky in frustration or collapse from exhaustion, we do it because we love it. We strive to explore and explain the unknown and to do that we work tirelessly for that data point. 

I Love Cyanotoxins!

I love working in Hengill!

It’s been great to be back in Iceland for another summer field work. I have returned with experience, many new questions and never-ending curiosity. In my time since last summer, I completed my senior year at St. Kate’s during which I had the incredible opportunity to work with Dr. Welter to continue research on the Iceland project. During the year I explored the effects of temperature on the biodiversity of algal communities. During my spring semester, I also developed a strong interest in cyanotoxins. Cyanotoxins are secondary metabolites produced by some cyanobacteria that are harmful to human health. The more I learned about these toxins, the more I wanted to know. I found out that while there has been a lot of research on cyanotoxins, there are still many questions and uncertainties surrounding them.

Samples of cyanobacteria

The project effort currently underway in Hengill utilizes the natural temperature gradient present across multiple streams to understand how stream communities and processes are affected by temperature. As I read more about how cyanotoxin production is strongly influenced by nutrients and temperature, I realized that this Iceland field site might be a great place to gain a better understanding of cyanotoxins. If any cyanotoxins are detected in Hengill, these streams could provide insight into how toxin production changes along a temperature gradient in stream ecosystems. 

In the time between sample processing, lab work and long field days, I have been developing ideas on how to best collect samples and test for cyanotoxins across a temperature gradient. There are many kinds of cyanotoxins and they can be produced by many different species of cyanobacteria. Trying to understand the details of cyanotoxins can seem overwhelming at times but it’s also what I find intriguing about them and is what motivates me to keep learning more. Regardless of what my samples amount to, I know this experience is helping me become a better scientist. I don’t see my interest in cyanotoxins fading anytime soon and I hope to have to opportunity to study them more in the future. 💚💚💚💚💚💚💚💚💚💚

It's the little things

I love my job as an ecologist. I get to travel, conduct research, collaborate, all in the beauty of the landscape! However, my job, as with any job, isn't always a ray of sunshine. In fact, many times my job as a field ecologist brings extreme challenges and tedious tasks. For example, it can be really mentally and physically draining when you have an 8-10 hour field day with constant rain and winds. You get soaked, cold, and grumpy. It's in these moments where I remember to appreciate and find happiness in the little things. It's the little things that provide the extra boost of motivation to keep going.

Adventures on an island off an island

Yesterday was only my 4th day in Iceland but we were already off on our first field trip excursion. It was a beautiful sunny day and we headed to Haimey, one of the Westman Islands, an archipelago off the southwest coast, for some hiking, sight-seeing, and birding. We had an early 7 am start from Reykjavik (which wasn't too bad considering the sun had been up since 3) and headed south to catch our ferry. After a scenic drive through Iceland and a short 30 minute ferry ride, we arrived at port. 

The small city is home to around 4500 residents and is surrounded by cliffs and two volcanic mountains, Helgafell and Eldfell. After a quick stop at Krónan to grab lunch, we began our hike up Eldfell. Eldfell last erupted in 1973 and is the youngest volcanic mountain in the world. The hardest part of hiking a volcano is the loose soil resulting in a two steps forward, one step back effect. At the top of the mountain we had a panoramic view of the island with cliffs on one side and the city on the other.

After Eldfell, we followed a random trail and discovered a cave! After taking some photos and pretending to be in Lord of the Rings, we began the most anticipated part of our trip, the search for puffins! Iceland has the largest population of puffins in the world and the Westman Islands are home to some of the largest colonies as well. With this in mind, we had high hopes. 

After a few hours of walking along the coast and peaking over cliffs we finally spotted our puffins! Small relative to the gulls and massive cliffs, the puffins zipped around the waves as tiny black specks. We spent the next couple hours sitting by the cliffs and enjoyed the scenic views. Once we returned to town, we followed the loud music coming from the center of the city and stumbled upon a celebration of Sjómannadagurinn (Sailor's Day). Celebrated throughout all the coastal towns of Iceland, the first weekend of June is dedicated to honor those who work at sea and in fisheries. My favorite event during the festival was the pillow fights. Historically used as a test of manhood, the pillow fight involves stepping out onto a plank overhanging the port and fighting until one of the players falls into the icy cold water below. 

Once we arrived back to the mainland, we had a quick drive before we arrived at our next site, the Beglengd Seljalandsfoss Waterfall. Standing at 75 meters, the waterfall cascaded over the edge of the plateau. The best part of this waterfall was that we could walk behind it! Following the path along the side, we ventured behind the waterfall for amazing views of the waterfall, rainbows, and some splashes of water. Overall, we had an amazing day exploring the island and experiencing the local culture. I can't wait to explore more of Iceland throughout the rest of the summer.
