Wave heights calculated from pressure sensor: Format: YYYYMMDD HHMM DDDD.DDD SSSS.SSS PPPP.PPP HHHH.HHH TTTT.TTT where YYYYMMDD = Date as year, month, day HHMM = Time as hour, minute DDDD.DDD = Depth (m) SSSS.SSS = Significant wave height at pressure sensor (m) PPPP.PPP = Wave period at pressure sensor (s) HHHH.HHH = Hsp - significant wave height at surface (m) TTTT.TTT = sper - wave period at surface (s) Sample data: 20070607 1400 9.307 0.262 5.333 0.930 5.545
