SAS webinar #5: The Arctic Ocean's carbon cycle

Tidspunkt

18. november 2024, 12:00-13:00

Sted

Online

The Synoptic Arctic Survey (SAS) is a researcher-driven initiative that aims to enhance ongoing ocean monitoring with ship-based measurements, to establish the present states of the Arctic Ocean ecosystem, carbon cycle and associated hydrography. SAS has coordinated a multi-ship survey using an international fleet of icebreakers and research vessels, where more than 25 cruises from 11 different nations collected a set of parameters across the Arctic Ocean in 2020-2022. This comprehensive dataset will allow for unprecedented assessments and provide a unique baseline to track future climate change and its impacts. For more information, please visit our website: https://synopticarcticsurvey.w.uib.no/

This webinar showcases recent updates on carbon exchange between the different pools in the carbon cycle of the Arctic Ocean. Marine carbon originates from river run-off (terrestrial) or air-sea fluxes (atmospheric) and is exported to the deep through large-scale currents where it feeds benthic organisms if there is sufficient light and other nutrients. There will be three solicited talks with room for questions and discussions:

Tracing the origins and fate of freshwater and organic carbon in the lower limb of the AMOC

Caroline Gjelstrup - Postdoc. at DTU Aqua, Denmark

Connectivity between Siberian river runoff and the lower limb of the Atlantic Meridional Overturning Circulation - Limnology and Oceanography

Arctic Ocean CO2 uptake

Sayaka Yasunaka - Professor at Tohoku University, Japan

An Assessment of CO2 Uptake in the Arctic Ocean From 1985 to 2018 - Global Biogeochemical Cycles

Seafloor primary production in the Arctic: Status and trends

Karl Attard - Associate professor at University of Southern Denmark, Denmark

Seafloor primary production in a changing Arctic Ocean - Proceedings of the National Academy of Sciences

The webinar will take place in Zoom. If you would like to join the webinar, please register to receive the meeting link:

Seminar: Climate change, the Norse and Inuit in Greenland - From Medieval Time to the Little Ice Age

Dear all, On Friday, June 6th, we will host an open seminar with Raymond Bradley, who is visiting us this week. Ray has been a leader within palaeoclimatology for decades and is an exciting discussion partner for any ideas you might have. If you would like to meet him, please get in touch with me. He will be around Thursday and Friday. Title: Climate change, the Norse and Inuit in Greenland - From Medieval Time to the Little Ice Age Who: Raymond S. Bradley, University of Massachusetts Where: Auditorium 5, 3rd floor, Realfagsbygget, Allègaten 41. When: Friday the 6th of June at 12:15 – 13:00 What: Norse settlers lived and farmed in southern Greenland from the late 10th to the early 15th century. Many explanations, including factors related to climate change, have been proposed to explain why they finally abandoned Greenland. But the Norse were not the only people living in Greenland at that time—the Thule Inuit occupied a large territory at the northern edge of Baffin Bay, arriving from the West around the same time as the Norse people. Although both cultural groups survived independently, there is evidence that they may have occasionally interacted. Deteriorating climatic conditions in the 15th century severely affected both groups of people, leading to an existential crisis for the Norse, and perhaps also for some of the more adventurous Thule explorers. Hope to see many of you on Friday! Cheers, Jostein

BCCR Monday seminar: On oxygen in western Canadian fjords

Next BCCR Monday seminar will be given by Jennifer Jackson, who is visiting BCCR from the Institute of Ocean Sciences, Fisheries and Oceans Canada. She will present her work "On oxygen in western Canadian fjords". The seminar will take place in the usual seminar room (4th floor of the West wing) at 11:00. Speaker information Dr. Jennifer Jackson is a coastal physical oceanographer at the Institute of Ocean Sciences, Fisheries and Oceans Canada (DFO). She received her MSc from the Department of Earth and Atmospheric Sciences at the University of Alberta and her PhD from the Department of Earth, Ocean, and Atmospheric Sciences from the University of British Columbia. She held postdoctoral positions at the University of Cape Town (South Africa), the University of Washington (Seattle, USA), and ASL Environmental Sciences (Victoria, Canada). Jennifer previously worked at the Hakai Institute where she led the Hakai Oceanography Program. Jennifer is known internationally for her work in Arctic and coastal oceanography, particularly fjord research and ocean climate. In October 2024, she took over DFO's Salish Sea oceanography and shore station programs.
