A phytoplankton bloom dominated by the pennate diatom Nitzschia
curta (Van Heurck) Hasle was observed during January-February 1983 at
a receding ice-edge in the Western Ross Sea, Antarctica. The core of
the bloom was found between 100-150 Km from the ice-edge. Nitzschia
curta cell densities up to 22 x 10⁶...
Dissolved silicic acid (Si(OH)4) and biogenic silica (BSiO2) concentrations were measured on four different cruises in the Southern Ocean along 1700 W from late October 1997 to mid-March 1998. These data were used to construct a vertically integrated Si budget in the surface layer from 58° to 68° S. Throughout...
As the frequency and intensity of wildfires continue to occur in the West, so does the need for measures intended to improve firefighter safety; public safety; and the protection of property, resources, and wildlife. Furthermore, as human activity in the expanding Wildland Urban Interface increases, so does the need for...
Boreal and temperate biomes host nearly half of the earth’s forested ecosystems. The temperate rainforests of the Pacific coast of North America constitute nearly half of all temperate rainforests on earth. Along the northern extent of this region, the perhumid and sub-polar rainforests of southeast and southcentral Alaska are among...
