Scientists present new long-term ecological research results at annual ocean sciences conference

Highlights include the health of U.S. East Coast salt marshes; influence of sea ice patterns on penguins; diet of blue whales in the California Current

Pacific sardine

The Pacific sardine is an important species in NSF's California Current Ecosystem LTER Site.


January 31, 2018

Are the U.S. East Coast's salt marshes healthy? How do sea ice patterns affect penguin populations in Antarctica? What diet do blue whales off California specialize in? Is every El Niño the same?

As the oceans continue to change in unprecedented ways, the annual Ocean Sciences Meeting (OSM) has become an important venue for exchanging new insights into these and other questions about marine ecosystems.

Co-sponsored by the American Geophysical Union, the Association for the Sciences of Limnology and Oceanography and The Oceanography Society, the 2018 OSM will be held Feb. 11-16 in Portland, Oregon.

Researchers affiliated with National Science Foundation (NSF) Long-Term Ecological Research (LTER) sites will give presentations on coastal and ocean ecosystems, including penguins in Western Antarctica; biogeochemical cycling in the oceans; microbial community structure in the sea; phytoplankton productivity; and salt marsh resilience.

Highlights of NSF LTER research include:

  • New approaches to monitoring phytoplankton and zooplankton communities.
  • Biogeochemical cycling in the California Current, Western Antarctic Peninsula and other regions.
  • Nutrient cycling, ecosystem metabolism and resilience in U.S. East Coast salt marshes.
  • Use of LTER data to study the influence of sea ice patterns on penguin and krill populations in Western Antarctica (special K-12 poster session).

Selected NSF LTER talks and posters are listed below; talks are listed in bold. All times are in Pacific Standard Time.
