“…In addition the DEM is composed of 63 years worth of data and therefore changes are expected to have occurred due to hurricanes, dredging and other anthropogenic changes (Lester et al, 2016;Smith et al, 2013).…”

“…Several key markets that will demand resources from the nearshore environment have been identified for future and continued development including, marine navigation, aquaculture, climate change adaption and mitigation, coastal resilience and disaster recovery. Technological innovation that yields contemporary nearshore seafloor maps with regular repeat observations will enable proper Marine Spatial Planning (MSP) and sharing of coastal waters (Foley et al, 2010;Lester et al, 2016). This is particularly important for Big Ocean States (Small Island Nations) that have limited data access (Flower et al, 2020) or where data does not match local needs (Kelman & West, 2009).Competing sectors of the Blue Economy will change the bathymetry of nearshore waterways and in a variety of ways.…”

Shallow nearshore coastal waters provide a wealth of societal, economic, and ecosystem services, yet their topographic structure is poorly mapped due to a reliance upon expensive and time intensive methods. Space‐borne bathymetric mapping has helped address these issues, but has remained largely dependent upon in situ measurements. Here we fuse ICESat‐2 lidar data with Sentinel‐2 optical imagery, within the Google Earth Engine cloud platform, to create openly available spatially continuous high‐resolution bathymetric maps at regional‐to‐national scales in Florida, Crete and Bermuda. ICESat‐2 bathymetric classified photons are used to train three Satellite Derived Bathymetry (SDB) methods, including Lyzenga, Stumpf, and Support Vector Regression algorithms. For each study site the Lyzenga algorithm yielded the lowest RMSE (approx. 10%–15%) when compared with validation data. We demonstrate a means of using ICESat‐2 for both model calibration and validation, thus cementing a pathway for fully space‐borne estimates of nearshore bathymetry in shallow, clear water environments.

“…CRNP suffers pressures from coastal tourism (Palafox & Zizumbo, 2009;Rioja-Nieto & Sheppard, 2008) that have been increasing over time (Palafox Muñoz et al, 2015). Coastal development produces sediment run-off (Roberts, Hanley, Williams, & Cresswell, 2017), cruise traffic generates sediment plumes (Lester, White, Mayall, & Walter, 2016), and snorkelling tourists and scuba-divers cause physical damage to coral reefs (Webler & Jakubowski, 2016) and promote coral diseases (Lamb, True, Piromvaragorn, & Willis, 2014).…”

Coral reef biodiversity is rapidly decreasing as a result of the loss of coral cover, which modifies the structure and functioning of the ecosystem. Understanding how coral reef communities respond in space and over the long term is essential in order to implement management strategies and reduce the effects of biodiversity loss on coral reefs. Fish, coral, and algae communities were used as indicators to evaluate changes in coral reef systems. The variation of these communities was studied in a marine protected area composed of three management zones in Cozumel Coral Reef National Park in Quintana Roo, Mexico, over a period of 11 years (2004–2014). The following parameters were monitored annually: (i) total fish density; (ii) fish trophic group densities; (iii) species richness and three fish diversity indices; (iv) relative scleractinian coral cover; and (v) relative macroalgae cover. In the years in which coastal development, such as the construction of a marina, took place, an increase in the abundance of territorial herbivorous and planktivorous fish was observed. As the coral recovered, macrocarnivores and sessile benthic invertivores were re‐established, whereas scraper herbivores showed no changes in the period of study in any of the three management zones. Coral cover recovery showed rapid phase‐shift reversal (phase‐shift, macroalgae dominance over coral) in the three zones. Even though the fish density and coral cover recovered, the diversity indices of each fish trophic group exhibited a reduction in the three management zones over time.

“…True, the mere reproduction of growth numbers in isolation may foster a misconception of cruise sector substance and role within the wider context (Papathanassis, 2019). For example, increasing cruise activities result in infrastructure and environmental costs that lower, or even offset, projected tourism revenues (Lester, White, Mayall, & Walker, 2016), while disclosed spending patterns might be overestimated for marketing or leveraging market power purposes. Still, the benefits to local economies are anything but insignificant.…”
