time-series plots of wind measurements

Figure 1. 1993 Observations in the western Gulf of Maine. Time series of winds measured at the meteorological buoy and freshwater inflow from the Kennebec/Androscoggin river system are shown. Positive wind stresses correspond to upwelling favorable conditions while negative winds correspond to downwelling favorable conditions. The timing of hydrographic surveys off of Cape Porpoise are indicated by the dotted lines. The observed plume width during the surveys are indicated in km with a subjective interpretation of the winds preceeding each survey; D indicates downwelling favorable winds prior to the survey while upwelling favorable winds are labelled with a U.
