Sediment toxicity and status of benthic invertebrate communities in the St. Lawrence River and its tributaries within the Massena Area-of-Concern Background Past water-quality issues in the St. Lawrence River at Massena, NY resulted in a determination that selected beneficial uses were impaired in a surrounding Area of Concern (AOC) and on the Canadian side of the international boundary (Cornwall, Ontario). The benthic macroinvertebrate community or “benthos” Beneficial Use Impairment (BUI) was designated degraded because impairment metrics were unavailable or inconclusive. Recent sampling efforts by New York State Department of Environmental Conservation (NYSDEC) as part of their Rotating Integrated Basin Studies (RIBS) program indicate that macroinvertebrate communities in some sections of the St. Lawrence River and its tributaries in the Massena AOC are...

The plankton (phytoplankton zooplankton) Beneficial Use Impairment (BUI) was so designated because impairment metrics were unavailable or inconclusive. Recent investigations, however, suggest that plankton communities are relatively healthy and no longer threaten the local ecosystem. Thus, the BUI for plankton may now be outdated in all, or parts of, the St. Lawrence River in the Massena AOC. The primary goal for the Massena (and Cornwall) Remedial Action...

Coordinated by the Core Science, Analytics, Synthesis, and Libraries (CSAS&L) Program of the United States Geological Survey (USGS), OBIS-USA, strives to meet national data integration and dissemination needs for marine data about organisms and ecosystems. OBIS-USA is part of an international data sharing network (Ocean Biogeographic Information System, OBIS) coordinated by the Intergovernmental Oceanographic Commission, of UNESCO (United Nations Educational, Science and Cultural Organization International Oceanographic...

As a continuation of our inaugural USGS National Climate Change and Wildlife Science Center (NCCWSC) project, this study examined the effects of climate and land use change on bird populations and their riparian and wetland habitats in the western US. Scientists at the USGS, academic institutions, and nongovernmental organizations (NGOs) examined the linkages between climate, hydrology,...

Global climate change would superimpose even greater stress on these ecosystems as indicated by climate change model predictions of higher temperatures and less precipitation in the southwestern United States. In partnership with the University of Arizona, the Nebraska Cooperative Research Unit, and the NASA Goddard Space Flight Center, USGS scientists have investigated (1) how climate change may alter the spacing and quality of critical wetland stopover habitats; (2) the sensitivities of migrating songbirds to loss of riparian forests due to climate change and water-use patterns; (3)...
