“…Values of dissolved oxygen recorded in SLS were higher than that found in other Rio de Janeiro lagoons such as Maricá (Oliveira et al, 1955;Guerra et al, 2011;Silva et al, 2014), Araruama (Debenay et al, 2001) and Itaipu lagoons . The values obtained in SLS indicated a favorable environment to the establishment of aerobic organisms of several trophic levels, since they require oxygen for their functions.…”

“…Secondly, the period from the mid-1970s to the 2000s is characterized by an increase of open dweller foraminifera species (e.g., C. crassa, Cornuspira involvens, G. praegeri) and higher abundance of P. cananeiaensis, which Debenay et al (2001a) related to the influx of suspended tests through the upstream transport of marine sediments. According to Debenay et al (2001a), the presence of P. cananeiaensis in the estuaries of southern Brazil indicates an inward transport of suspended material by tidal currents in these environments.…”

“…The occurrence of species of Bolivina, Buliminella, Elphidium confirmed the coastal environment. Species such as Pararotalia cananeiaensis and Discorbis williamsoni indicate marine influence in coastal environments (Debenay, et al, 2001;Eichler et al, 2012), and Globocassidulina subglobosa is related to marine environments of high energy (Mackensen et al, 1995). G. subglobosa is associated to the Current of Brazil (Boltovskoy et al, 1980) or Subtropical current -STSW (Eichler et al, 2012).…”

This work analysed assemblages of benthic foraminifera in core samples in lagoons from the Restinga de Jurubatiba Rio de Janeiro State, to observe paleoenvironmental changes and sedimentary deposition processes. Six cores were drilled (vibra-cores) until a depth of 1,56cm, in the Garças, Maria Menina, Robalo, Visgueiro, Catingosa and Pires lagoons. It was found that cores with sandy sediments presented lower abundance and richness of foraminifera species than fine sediment cores. Through the foraminiferal assemblages, four biofacies were characterized that reflected episodes of distinct evolutionary conditions for each lagoon. For the sandy lagoons, it was recorded the biofacies Ammonia/ Elphidium representing moderate marine influence, and the biofacies Aglutinated/Trochammina inflata representing the lagoon confinement. At the muddy lagoons, occurred the biofacies Ammonia spp./Elphidium spp./Haynesina germanica which represents paleoenvironments with high marine influence and the biofacies A. tepida/ A. parkinsoniana with low marine influence that favor conditions to opportunistic species. Radiocarbon dating allowed to record, in the sedimentary deposition process of the lagoons, Holocene submergence phases related to the marine transgressions. Keywords: Foraminifera; lagoons; Holocene; sea-level oscillation ResumoO objetivo do presente trabalho consiste em observar mudanças paleoambientais das lagunas da Restinga de Jurubatiba (RJ) através da análise de foraminíferos bentônicos. Foram coletados seis testemunhos (vibra-cores) de até 1,56cm de profundidade distribuídos nas lagunas Garças, Maria Menina, Robalo, Visgueiro, Catingosa e Pires. Os testemunhos com sedimentos predominantemente arenosos (Garças, Maria Menina e Robalo) apresentaram menor riqueza de espécies e abundância de foraminíferos do que os testemunhos com sedimentos mais finos (Catingosa, Visgueiro e Pires). Quatro biofácies de foraminíferos foram reconhecidas e refletiram episódios de condições evolutivas ambientais diferentes. Nas lagunas arenosas a biofácies Ammonia/ Elphidium foi associada a moderada influência marinha e a biofácies Trochammina inflata/ Aglutinantes representando confinamento das lagunas. Nas lagunas lamosas foi presente a biofácies Ammonia spp./Elphidium spp./Haynesina germanica associada a espécies calcárias marinhas sugerindo paleoambientes com alta influência marinha e a biofácies A. tepida/ A. parkinsoniana refletindo baixa influência marinha e condições propícias a espécies oportunistas. Datações radiocarbônicas permitiram registrar no processo de evolução das lagunas fases de submersão holocênica relacionadas com momentos de transgressões marinhas.
