Over the last decades, regional climate changes, erosion, and heightened agricultural runoffs have increased nutrient and particle input in rivers, unbalancing the biogeochemical cycle of this suspended material along estuaries. In this context, particle fluxes in the euphotic zone, a very productive layer and important to maintain the food chain and estuarine preservation, require better understanding. This study aims to evaluate particle sedimentation fluxes in the photic zone of the Cananéia-Iguape Estuarine-Lagoon Complex (CIELC), considering sectors under different salinities and trophic statuses. A cylindrical sediment trap was installed at the base of the photic layer to measure particle fluxes and photopigments. Meanwhile, water samples were taken to measure temperature, salinity, pH, dissolved oxygen, and nutrients. Valo Grande (a freshwater domain) showed high nutrient concentrations, in which high fluxes of phaeopigments and chlorophyll-b highlighted the contribution of vegetable detritus to particle sinking. In the Batatais mangrove creek, the high fluxes of organic particles (675.32 mg m-2 d-1) and chlorophyll-a (98.40 mg m-2 d-1) evinced a high contribution of microplankton to carbon sinking. During the winter of 2018, flocculation processes were evinced in the flood tide of the Cananéia Bay as an important driver of sedimentation rates, with considerable fluxes of inorganic particles (1161.20 mg m-2 d-1) and chlorophyll-a (83.27 mg m-2 d-1). In the summer of 2019, we observed a lower flux in total particles (451.24 mg m-2 d-1) in a period of haline stratification. In the Ararapira Channel, the lowest organic particle fluxes (<100 mg m-2 d-1) were associated with ultra-oligotrophic conditions, indicating a low influence of microplankton on sinking particles. These findings suggest that freshwater input, tidal variation, and trophic status are relevant controls of sinking particles in different CIELC sectors.

in the central part of the Red Sea. From 2000 to 2020, ERA5 reanalysis data on summer months of the Central Red Sea were used to match the time when the Tokar Wind Jet appeared. The diurnal variability of the Tokar Gap peaks in the early morning. The time series data of the wind speed showed that the Tokar Wind Jet appeared from July to August. The empirical orthogonal functions (EOF) analysis method was used to determine the modes of LHF variabilities. The sum of the first two modes of variability explained ~ 90.8% of the total variance. The first mode explained 80.8%, whereas the second mode represented approximately 9.9%. To examine the contribution of sea surface temperature (SST) and wind speed to the first two EOF principal components, the correlation coefficient and determination coefficient were applied. The results showed that SST had a CC of 0.90 and a DC of 81.99%, whereas wind speed showed a CC of 0.35 and a DC of 12.80%. These results may be explained by the strong link between SST and the specific humidity differences of saturation and actual vapor pressure. Partial correlation results indicate that there is an indirect relation between wind and LHF. In this study SST was the dominant factor, influencing LHF variability in the study area.

The Cananéia-Iguape estuarine-lagoon complex (CIELC), located in the State of São Paulo, Brazil, is considered an area of the Biosphere Reserve. However, an artificial channel built in the northern sector of the system (Iguape) has promoted an unnatural input of fresh water into the system, leading to enhanced drainage of terrestrial material into the estuary and influencing silicon biogeochemistry within the complex. This study used the distribution of different fractions of silicon along the system as a proxy for the freshwater input. The samples were collected during August, 2012 (winter) and February 2013 (summer) and analyzed for dissolved silicate, biogenic silica, and lithogenic silica. Dissolved silicate reached values above 200 µmol L -1 in the two seasonal periods, indicating the constant supply of terrestrial material in the northern sector of the system associated with fresh water. Southward, where the system is more preserved (Cananéia-Ararapira), the concentration decreased dramatically. Lithogenic silica (LSi) reached extremely high values of ~700 µmol L -1. Biogenic silica (BSi) showed concentrations up to 120 µmol L -1 with distribution more dependent on assimilation processes and the nature of the biological communities than on the source of fresh water. The availability of different forms of Si revealed remineralization, deposition, adsorption, and uptake mechanisms with different dynamics in the northern and southern sectors of the system, evidencing the environmental impact by the Valo Grande Channel.
位于巴西圣保罗州的canan - iguape河口-泻湖综合体(CIELC)被认为是生物圈保护区的一个区域。然而，在该系统的北部(Iguape)建造的人工河道促进了淡水的非自然输入，导致陆地物质进入河口的排水增强，并影响了综合体内的硅生物地球化学。本研究使用沿系统分布的不同分数的硅作为淡水输入的代理。样品于2012年8月(冬季)和2013年2月(夏季)采集，并分析了溶解硅酸盐，生物二氧化硅和岩石二氧化硅。在两个季节期间，溶解硅酸盐达到200µmol L -1以上，表明系统北段与淡水相关的陆源物质持续供应。向南，在系统保存更完好的地方(canan - ararapira)，浓度急剧下降。产岩二氧化硅(LSi)达到极高的~700µmol L -1。生物源二氧化硅(BSi)的浓度高达120µmol L -1，其分布更多地依赖于同化过程和生物群落的性质，而不是淡水来源。不同形式硅的可用性揭示了系统南北段不同动态的再矿化、沉积、吸附和吸收机制，证明了瓦洛格兰德水道对环境的影响。
