Inputs of Phosphorus from Precipitation to Lake Michigan

Precipitation Climatology of Lake Michigan Basin

A detailed climatological study shows that the average annual precipitation over Lake Michigan is 6 percent less than that of the land portion of the basin. This is contrary to results of most previous studies which indicated that lake and land precipitation were equal. However, the results of this study are more accurate than the earlier findings because they are based on more detailed informa...

Responses of phosphorus limited Lake Michigan phytoplankton to factorial enrichments with nitrogen and phosphorus1

Factorial nutrient enrichment expcrimcnts were conducted with water containing natural phytoplankton assemblages collected from Grand Traverse Bay. Levels of phosphorus (phosphate) were 5, 15, 25, 40, and 60 pg P liter4 and levels of nitrogen (nitrate) were 0.23, 0.84, and 1.12 mg N liter-l. Nutrients were maintained at these levels by additions at 2or S-day intervals. Two different analyses of...

Atmospheric mercury deposition to Lake Michigan during the Lake Michigan Mass Balance Study.

Wet and dry mercury (Hg) deposition were calculated to Lake Michigan using a hybrid receptor modeling framework. The model utilized mercury monitoring data collected during the Lake Michigan Mass Balance Study and the Atmospheric Exchange Over Lakes and Oceans Studytogether with high-resolution over-water meteorological date provided by the National Oceanic and Atmospheric Administration (July,...
