Brazil?s coastal line (7,367 km), starts approximately at Lat 5o 00? N and extends up to Lat 33o 00? S, in the Subtropical South Atlantic. Santa Catarina, it's second Southernmost state (Lat 25o 57? to 29o 24? S), occupies 1.1% of Brazil ́s surface area but encompasses 7.2% (561 km) of the country?s coast line. The 37 municipalities located at the state?s coastal zone, have 2.7 million inhabitants (41% of the state?s population), generate 30% of its GDP, and occupy just 9% of the state ́s land area. Based on more than 30 years of meteorological monitoring experience, state agency Epagri expanded its activities to Santa Catarina ́s coastal area. Over the last 5 years, 2 meteorological stations (MS) and 9 tide gauges (TG) were installed to form a new coastal monitoring network. This presentation reports the main results for sea level data analysis of 3 tide gauges (2901, Ilha da Paz; 2951, Florianopolis; and 2963, Imbituba). Data selected for the analysis represent monitoring activity of 643, 817 and 817 days (Jan/16 to Mar/18), respectively. Sea level data collection was performed through the use of radar sensors operating at local levelling (navigation purpose), using a 0.25 h sampling rate. Harmonic analysis was executed using TASK Windows Ed 2.1.0 software package, using 62 harmonic constants in every TG sea level data analysis. From North to South (2901-> 2951 -> 2963; 225 km total distance), the following statistics were recorded: maximum sea level, 2.125, 1.750, and 1.570 m, respectively; minimum sea level: -0.577, -0.620, and -0.660 m, respectively; mean sea level: 0.845, 0.550 and 0.4659 m, respectively. Following North to South data analysis, the difference between the highest and lowest record was: 2.702, 2.370, and 2.230 m; sampling failure was 0.34, 0.64 and 0.98% out of 15,431, 19,631, 19,631 reading possibilities; and residual means were 0.0001, 0.0000, and 0.0000 for TGs 2901, 2951 and 2963, respectively. Residual?s maximum values were 1.167, 1.077 and 1,142 m , which is about 138%, 196% and 245% larger than TG?s 2901, 2951 and 2963 mean sea level values, respectively. Finally, the equation that defines the tide type (O1+K1)/(M2 + S2) presented the following results for TGs 2901, 2951 and 2963: 0.324, 0.538, and 0.673, respectively, characterizing a mixed, mainly semidiurnal, tide type. Results show an interesting pattern in sea level from North to South in South Brazil, e.g., tides tending from a mixed semidiurnal type to a mixed tide type. Furthermore, results indicate that meteorological tides have a significant importance in the region, showing the importance of tide predictions services. We expect that in the near future these stations will operate in the GLOSS pattern of quality, increasing the number of tide gauges monitoring sea level in the South Atlantic.
