D on the west coast of New Caledonia is investigated, also making use of sufficient ground-truthing for model calibration and validation. Specifically, following a brief assessment on the present state of your art, we evaluate the performance of single-band ratio and multi-band ratios models applied to Sentinel-2 data. We 1st applied these models towards the shallowest element of your Poe Icosabutate Epigenetic Reader Domain Lagoon ( 4 m) after which to an extended location which includes bathymetry up to 25 m. Even so, choosing suitable bands remains a hard process and often final results in depthdependent performances, enabling superior accuracy for either shallow or deep waters, but not each. To overcome this issue, a new band optimization iterative strategy is proposed that optimally suited our BMS-986094 Anti-infection objectives to carry out effectively on shallow water lagoons displaying huge and sharp bathymetric alterations too as pretty irregular shallow coral reef places. two. Components and Solutions 2.1. Study Web site The study web-site, the Poe location, is positioned in the central element in the west coast of New Caledonia. It is part with the UNESCO’s Planet Heritage Lagoons of New Caledonia. It includes a 25 km2 shallow sedimentary lagoon bounded on the shore side by an extensive seagrass bed. This shallow lagoon, quasi rectangular-shaped, is bounded on its western side by a narrow pass referred to as the Sharks’ Fault (Faille aux Requins), and on its eastern side by the Gouaro Bay that is open onto the ocean. Lastly, around the southern side, Poe lagoon is delimited by a 15 km extended barrier reef (Figure 1). The lagoon itself consists of many benthoscapes (e.g., bottom sorts, substrates, depth variability) such as sand, quite low-density seagrass and algal beds, irregular coral structures and mixed hardground bottoms, that are additional abundant eastward. Having a maximum measured depth of about 25 m inside the pass plus a maximum depth of only four m within the inner lagoon, the study site demands a bathymetry retrieval process that is definitely correct for the narrow array of shallow depth identified all through the majority of the lagoon, while nevertheless getting correct within the 05 m variety around the pass region. These constraints are, having said that, really relatively common of most island shallow reef systems, bordered by deep channels and slopes. Taking into consideration this, we hereafter defined two regions of interest for the rest with the study (Figure 1). The very first a single, named the Shallow Lagoon Location (SLA), encompasses only the inner lagoon whoseRemote Sens. 2021, 13, x FOR PEER REVIEW4 ofRemote Sens. 2021, 13,throughout the majority of the lagoon, whilst still being correct inside the 05 m variety around 4 of 20 the pass region. These constraints are, having said that, truly fairly common of most island shallow reef systems, bordered by deep channels and slopes.
