“…when flood and ebb currents are typically highest) and minima at slack tides (i.e. when tidal currents are typically lowest), was consistent with observations from previous studies, as in a Brazilian estuarine system (Barboza et al, 2014) and a Tanzanian system (Bouillon et al, 2007c). Such patterns, combined with the strong correlation between POC and TSM, observed both during the tidal and river transect sampling (Fig.…”

“…For instance, studies have shown that changes in tidal levels (e.g. Barboza et al, 2014, Bouillon et al, 2007b, seasonal changes associated with river discharge (e.g. Guo et al, 2015;Hoffman and Bronk, 2006), and the distribution and mixing of different water masses along the salinity gradient (e.g.…”

“…Hydrodynamic data acquisition has become increasingly important in view of the pressures exerted on coastal and marine ecosystems in recent times. Natural and anthropogenic processes including weathering, urbanization, agricultural and industrial activities, tidal regime, precipitation rate, soil erosion and extraction of water resources are all major influences on the physicochemical properties of an estuary (Yang et al, 2012;Barboza et al, 2014;Shefat et al, 2020;Cereja et al, 2022).…”

Estuaries are important ecosystems that support biodiversity and influence the economy of the regions they occupy. Major physicochemical variables of Qua-Iboe River estuary in the Niger Delta region of Nigeria were assessed for ecosystem quality. The influence of tidal current on the spatial distribution of physicochemical parameters in the estuary was examined. Physicochemical parameters, including transparency, temperature, salinity, dissolved oxygen, density and pH were measured in-situ during the dry season. Tidal current velocities were monitored over spring and neap tidal cycles using the Langragian method and results indicated ebb dominance. The relationships between physicochemical parameters were statistically analyzed using Pearson’s correlation matrix. Based on Pearson’s correlation, density showed significant correlations (p < 0.05) with temperature, pH and salinity. Surface and bottom water temperatures significantly correlated (p < 0.05) with density, salinity, dissolved oxygen and pH. Spatial distribution maps of physicochemical parameters were plotted using ArcGIS Pro. Similarities and dissimilarities of surface and bottom water parameters were interpreted using cluster analysis. Results revealed two groups reflecting distinct physicochemical characteristics in the study area. Group one, representing upper and central portions of the estuary is defined by waters which are limnetic to oligohaline, slightly acidic to neutral with low dissolved oxygen (<4mg/l) conditions. The estuary showed limnetic conditions at the upper reaches due to the strong fluvial input by the Qua-Iboe River. Group two, representing the lower estuary, is characterized by mesohaline to normal marine waters; neutral to slightly alkaline pH, and low dissolved oxygen (< 4mg/l) conditions. This study is relevant for future monitoring and assessment of the estuary and similar tidal ecosystems.

“…Physico-chemical properties of an estuary is influenced by different natural and manmade processes such as precipitation rate, weathering, soil erosion, urban development, industrial and agricultural activities, and human exploitation of water resources (Pejman et al, 2009;Yang et al, 2012;Barboza et al, 2014).Factors such as the morphological characteristics of the estuary, water residence time, tidal regime, and rainfall also determine the ecological status and nutrient input to the estuary (Pamplona et al, 2013). Dissolved inorganic nutrients such as nitrite, nitrate, ammonium, and phosphate are the major essential nutrients for the phytoplankton growth (Dyer, 1986).…”

This study aimed to investigate physico-chemical properties of the Pasur River Estuarine (PRE) water connected to the Sundarbans mangrove ecosystem during the dry season for examining the ecosystem health. In-situ measurement and water sample collection were performed to assess physico-chemical properties at fifteen sampling stations along the main axis of the estuary in March 2018, April 2018, January 2019 and March 2019. Surface water temperature ranged from 20.7 to 33.7°C, pH from 7.1 to 7.9, and salinity from 8.5 to 16.2 PSU (practical salinity unit). Dissolved Oxygen (DO) concentration varied from 5.9 to 8.4 mg/L. Ammonium-nitrogen (NH4 +) was the dominant nitrogenous compound among the dissolved inorganic nitrogenous (NH4 + +NO3 -+NO2 -) compounds, and ranged from 0.11 to 2.11 mg/L. Higher NH4 + concentration in water column was largely attributed to release by tidal wash-out of the interstitial waters of the surﬁcial mangrove sediments. In contrast, phosphate concentration varied from 0.07 to 5.8 mg/L. The Pearson correlation coefficient was calculated to elucidate the correlation among physico-chemical properties during the dry season. Temperature showed a significant positive correlation with salinity and total dissolved solids (TDS), and negative correlation with DO. Similarly, salinity showed a significant positive correlation with TDS and negative correlation with DO. According to the Redfield ratio, the PRE is a nitrogen-limited estuarine system during the dry season. Ann. Bangladesh Agric. (2020) 24(1) : 1-16
