Theme title: Scientific Challenges in a Changing Arctic & Subarctic

The decline of biodiversity (the biomass, composition, and distribution of species) on Earth reflects the fact that the ability of Earth to sustain biodiversity in a dynamic environment has been seriously compromised by environmental stressors such as climate change and ocean acidification. Furthermore, the reduction of sea ice in the Arctic Ocean, which has progressed more rapidly than previously predicted, could exacerbate several environmental stresses, including ocean warming, acidification, and stratification. This meeting will focus on the observed and projected changes in the climate and marine environment of the Arctic and Subarctic and in the biological responses to these changes: How did the ancient climate and environment of the Arctic and its marginal subarctic regions change over time? How are the climate and environment of the subarctic and Arctic regions changing during the current Anthropocene? How do marine organisms in subarctic and polar regions respond to multiple environmental stressors? Active discussions will be encouraged to enhance our understanding of observed and anticipated changes and to explore how the natural sciences, humanities and socio-economic sciences can address and adapt to these challenges.

 

Session descriptions:

Challenges to the climate sciences in a changing Arctic & Subarctic –observations & models

Convenors: Ken Drinkwater, Takashi Kikuchi

The large changes in atmospheric and ocean climate during recent years in the Arctic and Subarctic regions are due to a combination of natural variability and global change. In this session we seek presentations that document these changes, seek to understand the mechanisms behind them, and/or develop scenarios of what is likely to happen in the future.   Investigations into both the Pacific and Atlantic regions of the Subarctic and Arctic are welcome, especially studies that compare and contrast responses in these different regions.

Speakers (invited): Satoshi Osafune (Japan Agency for Marine-Earth Science and Technology)

 

Challenges to the ecological and ecosystem sciences in a changing Arctic & Subarctic

Convenors: Franz Mueter, Sei-ichi Saitoh

This session will explore observed and predicted responses of marine organisms, populations, communities, and whole ecosystems of the subarctic and Arctic to reduced ice cover, changing temperatures, ocean acidification, and changes in advection and stratification. We invite presentations addressing biological responses at all trophic levels from bacteria to whales. We particularly encourage comparative studies among regions, such as among different marginal seas, between the Pacific and Atlantic and between the Subarctic and Arctic.

Speakers (invited): TBD

 

Challenges to the biogeochemical sciences in a changing Arctic & Subarctic

Convenors: Kumiko Azetsu Scott, Naomi Harada

Physical and chemical environments in the Arctic and sub-Arctic are changing rapidly due to global warming, accelerated hydrological cycles including sea-ice melt, increasing fluvial input and Greenland ice sheet melt, and ocean acidification. These changing conditions have significant implications for marine ecosystems. In this session, studies of biogeochemical changes in the Arctic and the sub-Arctic and interactions between these regions will be presented. Challenges to understanding the processes and controlling factors will be discussed. Observational, modelling and theoretical studies addressing these issues are welcomed.

Speakers (invited): Masahide Wakita  (Japan Agency for Marine-Earth Science and Technology)

 

Challenges to the humanities and socio-economic sciences for sustainability

Convenors: Alan Haynie, Mitsutaku Makino

This session is expected to reach mutual understanding between natural, social, human, and economic sciences that directly or indirectly relate with or depend on living marine resources. We would like to discuss actively to identify issues of concern toward the sustainable marine resources.

Speakers (invited): Orio Yamamura (Hokkaido National Fisheries Research Institute)

 

Pre/Historical Ecology of Subarctic Marine Ecosystems (with focus on NW Pacific and Sea of Okhotsk, Western Bering Sea)

Convenors: Ben Fitzhugh, Kana Nagashima (Paleoecology of Subarctic Seas (PESAS) Panel)

PESAS is a working group of ESSAS focused on synthesizing and expanding available information on the coupled atmospheric, oceanographic, ecological and human dynamics of the subarctic seas.  Many of our goals are derived from a desire to understand how climate changes have affected ecosystems that humans have relied on around the North Pacific and North Atlantic regions.

 

We invite abstracts from scholars with research interests in the reconstruction of Holocene paleoceanography, paleoecology, archaeology, anthropology, or history of the coastal/marine system.  We welcome papers the examine both long and shorter term histories, and those considering any time scale from LGM-Holocene to recent centuries of change. While we welcome papers on any regions of the North Atlantic and North Pacific (or Arctic), we expect and encourage submissions for this meeting especially on the NW Pacific, Western Bering Sea and Sea of Okhotsk.

 

Suggested topics:

  1. How have marine ecosystems changed since the start of the Holocene and over what scales/cycles?  How can these changes be connected to climate, physical oceanography, bottom-up and top-down ecosystem dynamics?

 

  1. What is the relationship between frequency and amplitude of variations in physical and ecological indicators? (Do longer period cycles — century and millennium — have higher amplitudes than shorter period fluctuations — annual to multi-decadal?). What is the relationship between temporal variability and spatial scale? Do millennial scale changes affect a larger area of ecosystems than decadal and annual scale variability?

 

  1. How has human use of marine ecosystems changed during the Holocene up to recent centuries (and even decades)? How have human populations and marine resource extraction technologies changed over this time? How have humans been affected by changing marine ecosystems or climate regimes?)

Speakers (invited): Iain McKechnie (University of Victoria), Yoshihiro Asahara (Nagoya University)

Directions to the hotel and venue

There are several ways to get from airports to the hotels in Sakuragi-cho, Yokohama. Taking a shuttle bus to get from Haneda airport (30 min) or Narita airport (90 min) to Minatomirai area.

  • From Haneda airport: Taking Keikyu limousine bus to Yamashita Koen Park/Minatomirai area/Yokohama Red brick Warehouse (one-way ticket: 720JPY) is the most convenient. The bus operates from 8:40 to 20:45 every 30 min or 1 hour (after 17:00). Please go to the ticket counter at 1st
  • From Narita airport: If you choose bus, please take Keikyu limousine bus to Yokohama City Air Terminal (one-way ticket: 3,600JPY, round trip thicket: 6,000JPY), walk 5-6 min to get to Yokohama station and change the train, JR Negishi-line and get off at the next stop (Sakuragi-cho). You can buy the bus ticket at the counter of the 1st floor (it is just in front of the exit of baggage claim area). If you like the train, please go to underground to take Narita Express (one-way ticket: 4,300JPY).
