Seaweed Symposium in Canada

Our Ikka-colleague Lina Rasmusson took part in the International Seaweed Symposium 2025 in Canada earlier this month presenting the biological results of our NAPA-project “The Ikaite columns – past and future, and prospects in a changing Arctic”. The main focus has been to compare the biological coverage on the ikaite tufa columns of Ikka Fjord in Southwest Greenland from how they appeared in 1995-97 to 2007 to recent years. Lina took part in last year’s fieldwork to Ikka Fjord and did diving herself among the columns (see featured photo above by Florian Huber). Some of the main research questions have been whether the biological life on the columns have diminished? Have the sea urchins increased in numbers and if so, why? What has happened to the coralline algae, have they also decreased in coverage? And has other marine algae taken over? Do we see signs of warming or heat spikes in the seawater of Ikka Fjord stressing the marine life and the ikaite mineralogy of the columns? Lina reports the presentation went well and with an engaged audience 🙂
