“…Dublin Bay (DB) is a wide C-shaped inlet located on the east coast of Ireland with an approximately 10 km entrance enclosing an area of about 296 km 2 ( Figure 1). This includes the intertidal zone of about 16 km 2 (Brooks et al 2016) in a relatively flat topography interrupted by tidally controlled related features, such as drainage channels and inlets. The Estuary is macro-tidal having a mean tidal range of 2.75 m with an average spring and neap tides of 3.60 m and 1.90 m, respectively (Mansfield 1992).…”

Bathymetry estimated from optical satellite imagery has been increasingly implemented as an alternative to traditional bathymetric survey techniques. The availability of new sensors such as Sentinel-2 with improved spatial and temporal resolution, in comparison with previous optical sensors, offers innovative capabilities for bathymetry derivation. This study presents an assessment of the fit between satellite data and the underlying models in the most widely used empirical algorithms: the linear band model and the log-transformed band ratio model using Sentinel-2A data. Both models were tested in two study areas of the Irish coast with different morphological and environmental conditions. Results showed that the linear band model fitted better than the log-transformed band ratio model providing coefficient of determination values, R 2 , between 0.83 and 0.88 (0 m-10 m) for the five images considered in the study. The closest fit was found in the depth range 2 m-6 m. Atmospheric correction, bottom type influence, and water column conditions proved to be key factors in the bathymetric derivation using these satellite datasets.

“…The subtidal benthic area (175 km 2 ) varies in depth from 25 m to a large inner area less than 5 m (Mansfield 1992). The shores of the bay naturally comprise small areas of rocky and pebbly shores and very large areas of predominantly fine sand (Brooks et al 2016). The bay is joined and bisected by the river Liffey in the south and north.…”

“…The Liffey is classified as a nutrient sensitive water body and is considered to be at high risk from diffuse pollution through groundwater and urban run-off and from point sources located within its catchment (O'Higgins and Wilson 2005;Brooks et al 2016;EPA 2018).…”

This paper evaluates for the first time the spatial distribution of a wide group of organic (phthalates, nitro, aliphatic, halogen, aromatic, phenol and amino compounds) and inorganic pollutants along the Liffey river in Dublin city. The work takes into account the effect of short-term weather conditions on the occurrence of these contaminants. The results showed that rainfall conditions affect the levels of pollutants along the river in the days following a rainfall event. In addition, the tributaries entering the river Liffey were not found to impact its water quality. In relation to organic pollutants, 2,4,6-trichlorophenol, 2-nitrophenol and phthalate compounds were found in many water samples between concentrations of 0.21 and 2.17 μg L−1. On the other hand, dimethyl phthalate was present in certain samples at levels around 100 μg L−1. The levels of these contaminants in the river were lower than the toxicity values reported in the literature. Regarding inorganic pollutants, nitrates were detected from 0.59 to 6.81 mg L−1 increasing from upstream to downstream. Based on the chemical nature and applications of detected pollutants, the river contamination can be mainly related to agricultural, industrial activities as well as diffuse urban contributions. These vary with location within a short distance and have the potential to impact aquatic biodiversity as the chemical composition changes with rainfall events.

“…1). Dublin Bay is a macro-tidal estuary with a mean tidal range of 2.75 m (Dyer, 1973) and an intertidal zone of about 16 km 2 (Brooks et al, 2016). In general, the entire bay presents a relatively flat topography with vast areas of fine sand combined with small areas of rocks and pebbles (Brooks et al, 2016).…”

In general, the entire bay presents a relatively flat topography with vast areas of fine sand combined with small areas of rocks and pebbles (Brooks et al, 2016). High nutrient loads, the deposition of large quantities of organic matter and undergoing regular dredging influence the water column conditions (O'Higgins and Wilson, 2005).…”
