... In comparison to existing global coarse (30 m) mangrove biomass datasets [90], the results of this study produced a more suitable AGC range corresponding to field AGC data, with promising R2 and RMSE values. More accurate information on mangrove biomass is frequently produced by higher satellite spatial resolution [91]. This finding is consistent with the finding of Nguyen [92], who compared the ability of Sentinel-2 and Landsat-8 to map the AGB of mangroves in Vietnam. ...

... A model relying on EO data towards the estimation of accretion rates in coastal wetlands was introduced by Jensen et al. (2022) [76]. Time series of Landsat data, along with available accretion records for the areas of interest, were employed towards the production of proxy variables that contribute to the phenomenon. ...

... Remotely-sensed TP estimation is complex, and Politi et al. [47] assessed 28 empirical algorithms sourced from the peer-reviewed literature using new satellite remote sensing data to identify the best water quality parameter retrieval algorithms in terms of accuracy and transferability and concluded that none of them exhibited satisfactory promise. One study showed that the best TSS retrieval model developed by a local dataset was accurate when applied to other areas [48]. Another UAV multispectral images without water sampling on 12 May 2022 in research area B were directly used to retrieve TP concentration combined with the established models. ...

... The average litter densities for the different zones and habitats ranged from 0.017 to 0.5 items/m 2 , which are comparable to the values reported by other surveys using UAV images (Gonçalves et al., 2020a), but lower than results obtained in Adriatic seas using the traditional approach (Vlachogianni et al., 2018). In addition, as reported by Andriolo et al. (2020aAndriolo et al. ( , 2021a, the different coastal habitats (beach, dune, back dune, saltmarsh) and coastal features (washover, beach wrack) have been identified through visual analysis of the orthophotos and DSM, highlighting the benefit in terms of human effort due to the difficulty to access to such areas like salt marshes, as reported also by Green et al. (2017) or Doughty and Cavanaugh (2019). ...

... Remote sensing technologies, such as lidar, InSAR, and image tracking analyses, are increasingly being used to characterize the precursory slope deformations leading to catastrophic failures (e.g., Lissak et al., 2020;López-Vinielles et al., 2020;Roberti et al., 2018;Williams et al., 2021). This information, combined with geological features (e.g., Zhang, S. et al., 2020) and stress regime information (e.g., Li & Moon, 2021), could lead to better estimates of total volume scenarios, and potential identification of multistage failure scenarios if distinct zones of movement are identified in the deformation patterns (Madson et al., 2019;Xiong et al., 2020). Observations of seismic data can provide insights into the volumes and initiation dynamics of past events, if properly interpreted. ...

... Furthermore, significant fluctuation in mangrove forest area in West Africa has occurred in recent decades (Andrieu, 2018). Mangroves in Senegal have experienced surface regeneration since the mid-1990s (Conchedda et al., 2011;Dièye et al., 2013;Andrieu, 2018;Fent et al., 2019;. However, the respective shares of species in regeneration processes differ according to the hydrosystems (Andrieu et al., 2020;Lombard et al., 2020). ...

... Population growth in multinational communities combines farming, ranching, mining, industry, and trade by sharing water and forest resources. To deal with this scope of environmental impacts, several studies focused on ecosystem service and biodiversity [99][100][101]. For instance, the administration of the Santa Cruz Watershed is governed by representatives from four nations, namely the United States, Mexico, Tohono O'odham Nation, and the Pascua Yaqui Tribe. The study area is a river, a limited aspect of the hydrosphere. ...

... Moreover, hyperspectral remote sensing is contributing to phytoplankton pigment mapping with dedicated algorithms [11] making use of continuous and dense spectral sampling. The benefits of merging hyperspectral imagery with the consolidated multispectral data will support future efforts to deal with, for example, the response of freshwater ecosystems to population growth and climate change [12]. ...

... To undertake hyperspectral measurement outdoors, an understanding of the systematic effect of changing zenith angle for spectral measurement and classification is important (Ma et al., 2020;Jensen et al., 2018). In this research, we indicate that the two major effects of increasing zenith angle are: (1) an increase of reflectance values and (2) an increase of noise levels, while center position of a spectral feature is quite consistent . ...

... The primary habitat in the region's northern part are the forests formed by the kelp Macrocystis pyrifera (Arafeh-Dalmau et al., 2021). This habitat supports the region's high diversity and productivity, providing both nursery and food for many species (Schiel and Foster, 2015;Ramírez-Valdez et al., 2017). Other important habitats, especially relevant in the southern section of the peninsula include intertidal, subtidal and deep rocky reefs, seagrass beds, mangroves and estuaries. ...
