| Abstract: | We used an extensive temperature and salinity data set to develop a statistically meaningful way of estimating mean temperature and salinity from discrete measurements in the mouth of Chesapeake Bay. From April 1992 to December 1998, the Center for Coastal Physical Oceanography completed 73 monthly hydrographic sections at high spring tide across the mouth of Chesapeake Bay. Time series of area weighted mean bay mouth temperature (MBMT) and salinity (MBMS) were calculated. We found that at any time the temperature at any location in the section correlated with the MBMT with a r2 of 0.95 or better. A similar analysis for salinity showed that the best correlation was about 0.9 with many locations below 0.8. A correlation between MBMT and temperature at a nearby tide station indicated it was possible to estimate MBMT from the temperature at the tide station to ±0.74°C (90% confidence interval). Salinity was not measured at the tide station, but the correlation at a location in the section similar to the tide station indicates that MBMS can be estimated with an error of ±1.5 (90% confidence interval). |
