I just came off the boat Ortelius, having spent an amazing ten days sailing around the South point of Spitsbergen to remote Edgeøya and Barentsøya, the Eastern islands of Svalbard. I had come on the SEES expedition as a seaweed scientist, which is a bit of an exaggeration. My scientific focus is more faunal than floral and in preparation for this trip, I dusted off seven-year-old memories of quadrat sampling and basic seaweed taxonomy. Besides getting to revisit a foggy but fascinating topic, I was also excited to experience the polar region after having been away for ten years since studying Arctic lakes and streams in Alaska. I didn’t know what to expect, but I hoped to see some beautiful nature, meet some interesting people, and collect some cold-water seaweeds, all of which I did!
What is so interesting about seaweeds in Svalbard you may ask? Seaweeds have to be tough in general to survive life in the intertidal, but especially in polar regions with rough seas, chilly temperatures, and a night that’s four months long. When researching a potential topic to propose for this expedition, I learned that sea ice is very important for determining seaweed presence in the Arctic intertidal, because winter sea ice can scrape seaweed away from the rocks. Kelps like Laminaria are safe from sea ice because they live deep underwater where ice doesn’t reach, but Fucus, which grows in the rocky intertidal, is at the mercy of ice scraping them off the beach. With rapid climate warming and less sea ice, we can expect more seaweeds in the Arctic. And so, in Spitsbergen, where it is relatively warm, I would expect to see a lot more older and less damaged seaweeds than in Edgeoya where it is colder and sea ice is more prevalent. Thus my mission for the expedition was born: collect seaweed seaweeds in both locations to see if I could find a difference in their cover and morphology.
I thought collecting seaweeds sounded easy, but it was easier said than done. Most of the scientists, including myself, had to land on the island of Edgeøya to do their research. However, there were around 110 expedition participants, half scientists and half tourists and the large group needed to be managed carefully. The biggest reason of canceling our landings was polar bears. People can be polar bear food, and so, in order to make a landing, the expedition staff needed to make sure that there were no polar bears nearby. This meant that before we landed the staff scouted the site from the boat and then on land for polar bears. And, even if we did make a landing, one needed to be near a rifle-carrying staff member at all times, and we could be evacuated if a bear was sighted. This was important for everyone’s safety, bears included— afterall, no one actually wanted to shoot a bear!— but it made for difficult fieldwork conditions because time could be cut short and rifle-carriers were in short supply for such a diverse group of researchers. A scientist collecting seaweed needs to collect them in a very different place than a scientist collecting moss. But with a lot of coordination and patience, we managed.

Fog and polar bears made the first days of the expedition challenging. On, the first day of the trip, a landing at Stellingsfjellet to see a colony of guillemots was planned and canceled because of the thick white fog. The second day was full of scrapped plans. The first planned landing at Kapp Lee was canceled due to large wave swells on the beach, then we sailed to a second nearby site, Rosenbergdalen, where the landing was also canceled due to a nearby bear. Another bear was sighted shortly after we reached the third alternative, Sundneset on Barentsøya, and so we couldn’t land there either. Having fog as a reason to cancel a landing is something that I expected, but the number of bears thwarting our plans was unexpected for everyone. Polar bears prefer to hunt seals from sea ice, but the sea ice had melted very quickly this year, leaving many bears stranded on Edgeøya. While the bears at our hoped for landing sites afforded me the possibility to see a polar bear for the first time, it was frustrating for the scientists who were foaming at the mouth to collect their samples, and also for the tourists who wanted to land and stretch their legs.
But it was not for nothing that we were cautious. On the third day we made our first expedition landing at Rosenbergdalen, where a bear was roaming the previous day. Though we landed and I was able to gather some sparse samples of seaweed for the first time, our visit was cut short when we had to evacuate because a polar bear was spotted nearby and heading our way. As I was in the coastal group and nearby the inflatable boats, I was one of the first people to be evacuated and so it was not a harrowing experience for me. But a few days later at Russabukta, I was happily loaded with samples of baby Fucus distichus and walking from the beach to join other scientists at a small patch of lakes, when Hans, the guide and rifle-carrier for our group, said he spotted a bear. I looked through my binoculars and could see a white dot as well. I would never have noticed the white dot on my own, but Hans, a much more experienced bear dot spotter, said the bear was sleeping. Sleeping bears are of course harder to spot because they don’t move and can easily be confused with ice or rocks, especially for a newbie bear-spotter like myself, but when I looked, the white dot was moving. Martine, another scientist, confirmed my conclusion: “That bear’s on the move.” And when it disappeared from view behind a small hillock in the rocky terrain, a frisson of fear went up my spine. Is the bear coming towards us?
Two days earlier, the bear that had chased us off Rosenbergdalen was seen from the boat sniffing around the spot where the vegetation scientists were collecting plants. The bear must have been disappointed that lunch escaped to sail another day.
