Tracing CO2 elements in the ocean
The surface waters of the vast Southern Ocean are suffering from `marine anaemia` – a serious deficiency in the micronutrient iron. Just as iron deficiency negatively affects the health and productivity of humans and other land-based creatures, so it affects the phytoplankton (microscopic marine plants) existing in the oceanic realm. The environmental consequences of this condition restrict primary production (photosynthesis) in the surface waters of the ocean. This means that less carbon dioxide is taken up from the atmosphere to fuel phytoplankton growth. The smaller the transfer of this greenhouse ...
Hurricane Ike’s effects linger in the Great Lakes
Although Hurricane Ike is long gone, its impact lingers more than a thousand miles from where it made landfall.  Runoff from tributaries dumped massive amounts of sediment into Lake Michigan, contaminating the water, compromising near-shore navigation and raising E coli bacteria to levels unsafe for swimming.   According to Richard Whitman, a U.S. Geological Survey (USGS) expert on beach health, `The local effects that Ike had on Lake Michigan`s Indiana shoreline, water depth, and water quality have been profound.`  While assessing Ike`s impact on the lake, Whitman noted that `The ...
