Seminar on Ocean Science by visiting professors from the US
We are pleased to invite all interested in climate change, marine ecology and fishery science to join us for a seminar held by visiting professors Lisa Levin (Scripps Institution of Oceanography) and Karin E. Limburg (State University of New York).
Hovedinnhold
Professors Lisa Levin (SIO) and Karin Limburg (SUNY) are collaborators on our HypOnFjordFish project. They will give us two lectures about anthropic disturbance in deep-sea environments and the role of earbones microchemistry to inform life-histories of fish who are having a hard time.
When: Monday 30th May 2022, 09:15-10:45
Where: Stort auditorium Høyteknologisenteret (HIB), Marineholmen
The lecturers:
Lisa Levin is a Distinguished Professor of Biological Oceanography at the Scripps Institution of Oceanography at UC San Diego. She is founder and co-lead of the Deep-Ocean Stewardship Initiative, which seeks to integrate science, technology, policy, law and economics to advise on ecosystem-based management of resource use in the deep ocean. She also helped establish and co-leads the Deep Ocean Observing Strategy, a program within GOOS. She is active in bringing climate science to policy and contributes to IPCC reports.
Her current research interests include biodiversity of continental margin ecosystems, and the effects of climate change (especially ocean deoxygenation) and human impacts on the deep ocean.

Karin Limburg is a Distinguished Professor in the Department of Environmental and Forest Biology at the SUNY College of Environmental Science and Forestry. Karin received her bachelor’s degree from Vassar College, a Master of Science at the University of Florida, and Ph.D. at Cornell University. Interested in the nexus of humans and nature, Karin’s studies have tended toward the transdisciplinary, but ecology has remained the central focus.
Karin is also a visiting professor at the Department of Aquatic Resources, Swedish University of Agricultural Sciences. Currently she serves as president of the International Fisheries Section of the American Fisheries Society, and is a member of the GO2NE working group.

The program:
09:15: Professor Lisa Levin (SIO) - Deep-Sea Biodiversity Challenges in the 21st century: Climate, Resource Extraction and Sustainability
Abstract: As the human population continues to grow, pressures on the deep ocean from climate change and resource extraction are inextricably rising, creating a serious situation in our planet's greatest frontier. This presentation will discuss the science of climate change in deep ocean environments, industrialization of the deep sea, deep ecosystem responses and effects on ecosystem services. It will consider the governance challenges these present, possible solutions and how scientific networks such as the Deep Ocean Stewardship Initiative (DOSI) and the Deep Ocean Observing Strategy (DOOS) can help address these.
10:00: Professor Karin Limburg (SUNY) - Through the Heads of Fishes: Anthropogenic Impacts on Fishes Revealed by Otolith Chemistry
Abstract: Fishes are increasingly subject to the accelerating, intensifying pressures of human activities, from direct alterations of habitat to climate change. As fishery biologists, we have our various “windows” through which we peer into fish population ecology: genetics, tracking, modeling, etc. Here I’ll discuss the insights that emerge from studying fish otolith chemistry. Otoliths are interesting biominerals because they are composed of aragonite (CaCO3) precipitated on a complex scaffolding of proteins, and as such, various trace elements and isotopes can become incorporated in both materials. Although we surely do not understand all the mechanisms driving incorporation, new insights are continually gained. The rich chemical detail that can be collected over individual fishes’ lives is time-stamped by the chronometric properties of otoliths. Thus, details of life histories are beginning to emerge that allow us greater interpretation of stresses. I will present a few case studies that illustrate how we can use otolith chemistry to understand the impacts of the Anthropocene: ocean deoxygenation; damming large rivers; and possible proxies of metabolism that can track lifetime condition. I’ll conclude with a few thoughts about future directions.

The "ocean economy"
Did you know that our oceans supply 50% of the world`s oxygen (1)? They also absorb about 30% of the anthropic CO2 emissions (2) and more than 90% of the excess heat (3).
The World Wide Fund for Nature (WWF) estimated the yearly value of goods and services supplied by the ocean to be around $2.5 trillion (4). Hundreds of millions of people rely on ocean biodiversity and services, which provide us with food, energy, water, trade and tourism (5).
