The Ocean Sciences Meeting (OSM) has become an important venue for scientific exchange across a wide range of marine science disciplines, especially as human impacts on the oceans reach unprecedented levels. OSM, co-sponsored by the American Geophysical Union (AGU), the Association for the Sciences of Limnology and Oceanography (ASLO), and The Oceanography Society (TOS), will be held 11–16 February, in Portland, Oregon.

Researchers representing several LTER sites will present talks or posters on a range of coastal and ocean topics including biogeochemical cycling, microbial community structure, phytoplankton productivity, and ecosystem resilience.

Highlights of LTER research being presented at OSM include:

  • Novel approaches to monitoring phytoplankton and microzooplankton communities at multiple spatial and temporal scales
  • Physical properties and biogeochemical cycling in the California current, Western Antarctic peninsula, and other regions
  • Nutrient cycling, ecosystem metabolism and resilience in U.S. east coast wetland systems
  • Poster presentation by a high school student who used LTER data to study the influence of sea ice patterns on penguin and krill populations in Western Antactica (special K-12 poster session)

The full list of LTER science-related talks and posters can be found below. Oral presentations are listed in bold font.
