“…Immediately adjacent to PI reefs, the National Oceanic and Atmospheric Administration (NOAA) Tide Station 8656483 revealed an 18‐cm increase in mean sea level across 1973–2015 (~3.5 mm year −1 RSLR) (NOAA, 2021). Finally, Beaufort Inlet dynamics may have also contributed to the salinity‐driven faunal patterns we observed in 2013–2015 (but not long‐term salinity patterns per se), as Beaufort Inlet widened from 1.15 km in 2010 to 1.75 km in 2015 (Seymour et al, 2019), furthering the coastal ocean influence in the NRE.…”

Foundation species, such as mangroves, saltmarshes, kelps, seagrasses, and oysters, thrive within suitable environmental envelopes as narrow ribbons along the land–sea margin. Therefore, these habitat‐forming species and resident fauna are sensitive to modified environmental gradients. For oysters, many estuaries impacted by sea‐level rise, channelization, and municipal infrastructure are experiencing saltwater intrusion and water‐quality degradation that may alter reef distributions, functions, and services. To explore decadal‐scale oyster–reef community patterns across a temperate estuary in response to environmental change, we resampled reefs in the Newport River Estuary (NRE) during 2013–2015 that had previously been studied during 1955–1956. We also coalesced historical NRE reef distribution (1880s–2015), salinity (1913–2015), and water‐quality‐driven shellfish closure boundary (1970s–2015) data to document environmental trends that could influence reef ecology and service delivery. Over the last 60–120 years, the entire NRE has shifted toward higher salinities. Consequently, oyster–reef communities have become less distinct across the estuary, manifest by 20%–27% lower species turnover and decreased faunal richness among NRE reefs in the 2010s relative to the 1950s. During the 2010s, NRE oyster–reef communities tended to cluster around a euhaline, intertidal‐reef type more so than during the 1950s. This followed faunal expansions farther up estuary and biological degradation of subtidal reefs as NRE conditions became more marine and favorable for aggressive, reef‐destroying taxa. In addition to these biological shifts, the area of suitable bottom on which subtidal reefs persist (contracting due to up‐estuary intrusion of marine waters) and support human harvest (driven by water quality, eroding from up‐estuary) has decreased by >75% since the natural history of NRE reefs was first explored. This “coastal squeeze” on harvestable subtidal oysters (reduced from a 4.5‐km to a 0.75‐km envelope along the NRE's main axis) will likely have consequences regarding the economic incentives for future oyster conservation, as well as the suite of services delivered by remaining shellfish reefs (e.g., biodiversity maintenance, seafood supply). More broadly, these findings exemplify how “squeeze” may be a pervasive concern for biogenic habitats along terrestrial or marine ecotones during an era of intense global change.

“…From both lidar and SfM, 3D point clouds ( Figure 2B and Supplementary Video S1) can be used to create digital surface models, and digital elevation models ( Figure 2C) when data are georectified within a vertical datum. UAS-derived 3D modeling has been conducted in a variety of environments including shorelines (Gonçalves and Henriques, 2015;Seymour et al, 2018;Lowe et al, 2019;Seymour et al, 2019;Casella et al, 2020), several shallow-water/tidal habitats (Long et al, 2016;Ventura et al, 2016;Casella et al, 2017;Kalacska et al, 2018;Windle et al, 2019), and to study hydrological dynamics in wetlands (Capolupo et al, 2015;de Roos et al, 2018;Harvey et al, 2019).…”

“…While not serving as a replacement for finite sediment surface measurements like those obtained from saltmarsh Surface Elevation Tables (SETs, Cahoon, 2015), UAS-derived elevation data could help determine the overall scalability of SET measurements over a larger area. UASs have been used to track changes to barrier islands and other coastal environments over the course of months to years capturing morphological changes to the landscape (Seymour et al, 2019). Similarly, Marteau et al (2017) used these methods to track geomorphic change of a restored riverine environment to assess restoration outcomes.…”

“…In the case of a living shoreline restoration project, UAS provide significant opportunities to assess how natural systems dampen storm energy compared to artificial or unstructured shorelines. Recognizing this advantage, UASs are incorporated into post-storm monitoring in coastal systems internationally (Turner et al, 2016;Seymour et al, 2019;Casella et al, 2020). Studies conducted on living shorelines to assess their resilience and shoreline protection against storm impacts (e.g., Smith et al, 2018) would benefit from the incorporation of UASs, which would expedite field sampling and reduce unintentional, but inevitable, impacts of direct sampling within the habitat (Figure 1).…”

Assessing, implementing and monitoring ecosystem restoration can be a labor intensive process, often short term (<3 years), and potentially destructive to the habitat. Advances in remote sensing technology are generating rapid, non-destructive methods for siting, executing and monitoring restoration efforts, particularly in fragile marine environments. Unoccupied aircraft systems (UAS), or drones, are a highly flexible method for accessing and remote sensing ecosystems with on-demand capabilities, greater resolution than sensors from satellites and occupied aircraft, and the ability to cover large areas quickly. With the variety of platforms and payloads available, UASs are providing a suite of tools for conservation practitioners to properly plan marine ecosystem restoration projects and evaluate their success. Both conventional and specialized sensors coupled with image processing techniques can be used to gauge impact to and recovery of entire ecological communities. For example, high-resolution, multispectral imaging allows for discernment of population changes across trophic levels, concurrent with the discrimination of species (including rare) across a landscape, and detection of vegetation stress. Structure from Motion photogrammetric processing provides centimeter-scale three-dimensional models of habitat structure to measure ecologically significant aspects like rugosity and assess their change through time. Water quality around a broad impacted area can be remotely monitored via a number of payloads before and after restoration. Additionally, specially designed payloads can be used to manually disperse seeds or materials for restoration applications without disturbing the habitat. UASs have increasing potential to reduce the costs (both time and money) associated with restoration efforts, making site assessment and long-term, broad-scale monitoring more achievable. Here we present a review of the applications of UASs in marine ecosystem restoration with an overview of the special considerations of using this technology in the marine environment.

Landform evolution is mainly to study the coupling model of heat conduction law and landform movement law in the earth so as to obtain the landform distribution millions of years ago and the change law of landform in this region [1]. The problem of terrain reconstruction has attracted more and more geologists and mathematicians' attention abroad. From the existing studies, it can be seen that the study of landform involves the thermal structure inside the earth, river erosion, wind erosion, rainfall, and the impact of human factors (such as artificial canal excavation, increase and decrease of vegetation, large population influx, etc.) [2]. Jinan is rich in spring water resources, and is known as the "Spring City". Spring water plays an important role in people's
