Elevated Methylmercury in Water and Aquatic Food Webs in Lagoons
We assessed mercury contamination of water, sediment, and selected aquatic biota from two lagoons in the Apostle Islands National Lakeshore (southern Lake Superior). These nearshore lagoon systems appear to be mercury-sensitive environments with unusually high rates of production of methylmercury, a highly toxic compound that readily bioaccumulates in aquatic food webs. Concentrations of methyl...
متن کاملSeasonal Succession of Free-Living Bacterial Communities in Coastal Waters of the Western Antarctic Peninsula
The marine ecosystem along the Western Antarctic Peninsula undergoes a dramatic seasonal transition every spring, from almost total darkness to almost continuous sunlight, resulting in a cascade of environmental changes, including phytoplankton blooms that support a highly productive food web. Despite having important implications for the movement of energy and materials through this ecosystem,...
متن کاملWestern Antarctic Peninsula physical oceanography and spatio–temporal variability
Peninsula (WAP). The dataset offers the most long-lived consistent CTD-gridded observations of Antarctic waters collected anywhere in the Southern Ocean. The physical characteristics, water column structure and spatio–temporal variability of the various properties are examined for physically consistent and ecologically important patterns and modes of variability. Unique findings of note include...
متن کاملA doubling in snow accumulation in the western Antarctic Peninsula
[1] We present results from a new medium depth (136 metres) ice core drilled in a high accumulation site (73.59 S, 70.36 W) on the south-western Antarctic Peninsula during 2007. The Gomez record reveals a doubling of accumulation since the 1850s, from a decadal average of 0.49 mweq y 1 in 1855–1864 to 1.10 mweq y 1 in 1997–2006, with acceleration in recent decades. Comparison with published acc...
