Scenario 1:  State-level management staff wants to look at phosphorus trends in Lake Erie and wants the following information:

• Total phosphorus and chlor-a trends in the western basin of Lake Erie (i.e. a time series, plus the box and whiskers plot to show overall variability)
• Total phosphorus and chlor-a trends from an individual station (Erie 59 due to its proximity to the Maumee River)
• Total phosphorus and chlor-a trends in the central basin of Lake Erie
• Loading information (USGS gauge data) from the Maumee River

Scenario 2:  Scientist interested in changes in DCM through time in Lakes Michigan and Huron and wants the following information:

• Average chlor-a values at depth for early in the time series (say, pre – 2002) versus more recent values
• Wants to make a comparison for Lake Huron versus Lake Michigan
• How is depth of DCM related to water temperature (display both profiles on the same graph, or multiple graphs?)
