The results revealed significant differences between the three bathymetric areas based on SSL and EI descriptors, with micro-nektonic communities in the transition area exhibiting intermediate characteristics between those in the inshore and offshore areas. The relative abundance of micro-nektonic communities decreased from shallow coastal areas to deep offshore areas, with a mean S_v from echointegration of −66.43, −74.39 and −73.65 dB for inshore, transition and offshore, respectively. The inshore area is different from the transition and offshore areas, which is confirmed by diel vertical migration (DVM) analyze through vertical profiles. All areas exhibited classic DVM type I; however, offshore and transition areas also presented unexpected DVMs of type II, <em>i.e.</em>, organisms descend deeper during the night, displaying distinct vertical profiles compared to the inshore area. This suggests that the functional and specific composition of pelagic micro-nektonic communities differed between inshore and offshore areas, indicating that organisms adjust their responses to their environment. Over two decades, the three bathymetric areas showed a significant increase in pelagic relative biomass and variation in SSL spatial structure. The number of SSLs significantly increase, from 0.97 to 1.05 inshore, from 1.75 to 2.25 in the transition area and from 2.2 to 2.7 offshore. Nevertheless, micro-nektonic communities reacted differently to interannual changes depending on the bathymetric areas, such as the minimal depth of the shallowest SSL.

In the first part, the tidal analysis of sea level data shows the dominance of M2 tides followed by S2, N2, K1, and O1 at all the stations. The tides are usually semidiurnal in nature over BoB, represented through the form factor, which is maximum over Ennore (0.21) and minimum over Gardenreach (0.10). The tidal amplitudes increase gradually northward along the western BoB due to interaction with the shallow continental shelf. The topography and coastal geometry also impact the shallow-water constituents (M4 and MS4) significantly at all the locations. Another noteworthy finding is the higher amplitude of M2 tide during the post-monsoon seasons because of the higher stratification of the water column. In the second part, the presence of different non-tidal signals from the residual sea level and altimetry gridded data are studied as well. The correlation coefficient between Sea Level Anomaly (SLA) data from altimetry and the Tide Gauge data are as high as 0.94, 0.91, and 0.90 at Paradeep, Kakinada and Ennore, respectively. The spectral analysis ensures the dominance of the signals with periodicity of 20–60 days in the BoB, which is probably caused due to the monsoon ISOs and Madden Julian Oscillations. The 10–20 days oscillations are also observed with significant amplitudes primarily at Gardenreach which attributes to the Quasi-Biweekly Oscillations. The signature of seasonally varying coastally trapped Kelvin Waves is also identified on the western BoB from both the satellite and Tide Gauge data. The strength of the intraseasonal variability significantly increases during negative Indian Ocean Dipole years with respect to the positive years.

The model's realistic representation of the cross-shore SST supports the interpretation that the observed variability is governed, in the inner-shelf, by the offshore separation of upwelling divergence and, over the mid-shelf, by offshore Ekman transport and mesoscale circulation. The observation of an alongshore low SST/low Chl-<em>a</em> band, bounded by the 30 m and 50 m isobaths, for the days of maximum wind stress, matching the model's solution for the outcrop of colder subsurface waters, constitute a satellite-based evidence of upwelling separation from the coast.

In many ecosystems ponds can be a valuable resource for the conservation of freshwater biodiversity. The Castelporziano Presidential Estate is a Mediterranean protected area hosting numerous ponds which are suffering severe droughts and a general decline in number and hydroperiod length. Hydroperiod changes can be particularly relevant for biodiversity inhabiting ponds, in particular diatom communities. Here, for the first time, we evaluate the conservation status of Mediterranean ponds inside the Castelporziano Reserve. The aims of this research are to i) investigate the influence of environmental variables on diatom communities of ponds; (ii) analyse diatom community structure in function of species richness and competitive interactions; (iii) highlight the potential and effectiveness of diatom ecological guilds in supporting the interpretation of the ecological status of threatened small waterbodies. Overall, 122 diatom taxa in the 29 ponds were described. <em>Nitzschia</em> (18 species) was the most species-rich genus, followed by <em>Gomphonema</em> (14) and <em>Navicula</em> (13). 17 species were included in the Red List of endangered species. Intra-pond distance and anthropogenic impacts didn't influence diatom assemblages. On the contrary, diatom communities were influenced by altitude and the distance from the sea. Furthermore, temporary ponds showed the lowest values for Shannon, evenness and Simpson indexes Considering Beta-diversity, both Bray-Curtis and Jaccard dissimilarity matrices highlighted a large dissimilarity between sampling sites. Inter-variability between sites and intra-variability within the sites resulted both very low. Our results highlight that diatom species are not influenced by hydroperiod length. Moreover, a structured diatom community emerged, where segregation processes predominating over aggregation ones. Finally, the average water quality of the ponds, calculated using the EPI-D index, was described as “good”. This study represents the most complete checklist of diatom communities inside coastal ponds of Castelporziano, providing valuable insights into the effects of natural and anthropogenic influences on ponds conservation and management activities. However, spatial-temporal changes and anthropogenic impacts should be deeply investigated.</div></div>","PeriodicalId":50618,"journal":{"name":"Continental Shelf Research","volume":"283 ","pages":"Article 105359"},"PeriodicalIF":2.1,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142664177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sea levels around the Panama Canal are dominated by ocean tides but local tidal evolution is still unexplored to date, which motivates present study. Two secular tide gauges longer than 110 years (Cristobal and Balboa) around the Panama Canal are analyzed to explore multi-time scale tidal variability. It is found that observed nodal modulations of major constituents are generally consistent with the equilibrium tidal theory. M₄ and Mf nodal modulations notably deviate from the theory possibly due to non-linear processes. Long-term trends exist in main semi-diurnal tides, while main diurnal tides do not have significant secular trends. It is worth mentioning that M₄ and MS₄ amplitudes at Cristobal have halved in the past century. Moreover, tidal parameters of major constituents at Cristobal and Balboa show abnormal mutations in 1908, 1990–1998, and 2013–2018. As a result of changing tides, tidal asymmetries at Cristobal are significantly weakened while the number of high tides per year is notably decreased. Tides at Balboa are almost symmetric. Tidal regimes at Cristobal can periodically shift between mixed diurnal tides and mixed semi-diurnal tides following the 18.61-year nodal cycle. However, such regime shift has disappeared since 1997 due to secular negative trends in M₂ amplitudes.
