Resumo: | Sea level fluctuations on the coast of Santa Catarina during the fall of 2018 were studied to evaluate the contribution of the meteorological tidal phenomenum in comparison with predicted astronomical tides. The time series of the open sea tidal stations (Ilha da Paz, Balneário Camboriú, Imbituba and Balneário Rincão) were quality controlled, interpolated at 15-minute intervals and standardized by mean sea level. The storm surge, evaluated in the inertial scale, presented amplitudes of 30 to40cm in relation to the mean sea level and occurred in periods ranging from 5 to 10 days, corresponding to the temporal scaleof the frontal atmospheric systems. There has been a reduction in the amplitude of astronomical tides towards the south of Santa Catarina, so that the relative contribution of the storm surges to sea level variation exceeds 90% in extreme cases. Based on these results, caution is advised in the use of astronomical tidal tables, especially for coastal navigation on inbound and outbound vessels in estuaries, bays and inlets. |

As séries temporais das estações maregráficas situadas em mar aberto (Ilha da Paz, Balneário Camboriú, Imbituba e Balneário Rincão) foram consistidas, interpoladas para intervalos de 15 minutos e padronizadas pelo nível médio do mar. A maré meteorológica, avaliada na escala inercial, apresentou amplitudes de 30 a 40 cm em relação ao nível médio no mar e ocorreu em períodos que variaram de 5 a 10 dias, correspondendo a escala de passagem dos sistemas atmosféricos frontais. Observou-se uma redução nas amplitudes das marés astronômicas em direção ao sul do estado, de forma que a contribuição relativa das marés meteorológicas na variação do nível do mar ultrapassa os 90% em casos extremos. Com base nestes resultados recomenda-se cautela no uso das tábuas de maré astronômica, especialmente para navegação costeira na entrada e saída de embarcações em estuários, baías e enseadas.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2020-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/53510.52945/rac.v33i1.535Agropecuária Catarinense Journal; Vol. 33 No. 1 (2020); 61-67Agropecuária Catarinense; v. 33 n. 1 (2020); 61-672525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/535/680https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSalles de Araujo, Carlos Eduardo2021-06-01T16:36:59Zoai:ojs.publicacoes.epagri.sc.gov.br:article/535Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2021-06-01T16:36:59Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false |
