Increases: Wind speed
Decreases: Data quality
Saildrone research vehicles are relatively slow, moving at about three knots. Both vehicle speed and noise increase with wind speed, resulting in lower data quality. Saildrones have difficulty making progress in low wind conditions, requiring several days to complete a transect that requires a few hours on a survey vessel. The quality of data collected by Saildrones is especially poor in turbulent ocean conditions (storms, high wind events) because the vehicles are relatively small and lightweight, which makes them prone to substantial pitch and roll that in turn produces frequent acoustic ping dropouts (no data) relative to the survey vessel data.
In the table, select variables pertaining to Saildrones research missions that based on the information provided would be inversely proportional – one increasing and one decreasing. Make only two selections, one in each column.
