Influence of a Drought Event on Hydrological Characteristics of a Small Estuary on the Amazon Mangrove Coast

Abstract: The effects of atypical climatic conditions, such as those of a drought event, are remarkably accentuated in minor estuaries filled with sediments and with reduced or sporadic freshwater input, where the salinity intrusion is pronounced. To understand these effects, hydrological and hydrodynamic parameters were evaluated during a drought period in a small estuary located on the eastern Amazon coast in northern Brazil. Five campaigns were conducted between June 2012 and June 2013. Samples were collected from th… Show more

“…Still, all components of the food web are affected when community changes such as species diversity and biomass are induced by drought. Depending on the estuary, phytoplankton biomass may be higher (Brazil: Barroso et al, 2018; USA: Cira et al, 2021) or lower (Brazil: Pereira et al, 2017; USA: Wetz et al, 2011) during drought. Higher biomass can be concomitant with lower biodiversity (Cira et al, 2021).…”

“…The annual estimate of water CO 2 -e production for the atmosphere was 3.35 Gg CO 2 -e yr -1 when the area of the Mojuim River basin (45.5 ha) is taken into consideration. [87][88][89][90][91][92][93][94][95][96][97][98][99]…”

“…The precipitation in Amazon estuary exhibited strong seasonality, high precipitation result in an increase of the fluvial discharge of freshwater, together with an increase in the quantity of suspended particulate organic matter (Dittmar & Lara, 2001), which results in an increase in the productivity of the environment (Asp et al, 2018;Costa, Atique, Costa, & Pereira, 2011;Pereira et al, 2017).…”
