(a) Mean high water (MHW) - the average of all high water levels; 



(b) Mean low water (MLW) - the average of all low water levels; 



(c) Mean sea level (MSL) - the average of hourly tidal heights; 



(d) Mean range (MR) - the difference between MHW and MLW; 



(e) Mean tide level (MTL) - MHW plus MLW divided by 2; 



(f) Mean higher high water (MHHW) - the average of the highest 

 high water levels; and 



(g) Mean lower low water (MLLW) - the average of the lowest low 

 water levels. 



4. Meteorological Data . 



The meteorological data are based on daily (excluding weekends and holi- 

 days) observations made about 0700 e.s.t., coincident with the daily sensor 

 maintenance and LEO observations. Appendix B contains monthly summaries of 

 the daily weather observations, along with a chart record availability table. 

 Tables 12 and 13 are annual meteorological data summaries for 1978 and 1979.
