Sandy Shores (Destroy Map)



It is possible for free players to obtain treasure trail items in sandy clues. Treasure trail rewards obtained from this also count towards the Treasure Trail collection log. One strategy to quickly complete clues is to do so on a free world. As free players do not get members clues, this makes the player more likely to obtain a clue that does not require them to leave the area. However, be sure to open the caskets on a members server if possible because free users will only get up to two items.


The Maldives is the lowest country on the planet. The average height of its 1,200 islands, which spread across 1,000 miles (1,600 kilometers) in the Indian Ocean, is only four feet (1.2 meters) above sea level. Already, ever-higher waves encroaching on the shores of the lowest islands erode beaches and there is nowhere for residents to retreat to when a tropical cyclone or a tsunami wave approaches. Residents have even been forced to move as the world's first climate change refugees.


Propubilica and the Honolulu Star-Advertiser have produced a joint story into how sea walls are helping to cause coastal erosion in Hawaii. Over the last one hundred years Oahu, Maui and Kauai have lost around 25% of their sandy beaches. To help protect their homes from rising seas the owners of sea-front properties often erect sea walls. These sea walls then contribute to the loss of Hawaii's sandy beaches - as over time waves hitting these sea walls pull the sand away from the shore.


Hawaii's Beaches are Disappearing uses a combination of drone captured video, aerial imagery and maps to document and explain the loss of sandy beaches in Hawaii. These disparate element are tied together using Mapbox's Scrollytelling Template. As you progress through the story maps are used to show you where properties have built sea walls and where Hawaii's sandy beaches have disappeared. Overhead aerial imagery and drone shot videos provide stark illustrations of the power of the sea hitting property sea walls.


Male green iguanas can grow to over five feet in length and weigh up to 17 pounds. Females can also reach five feet in length but usually do not exceed seven pounds. Females typically reach reproductive maturity at two to four years of age. Green iguanas typically mate in October through November in their native range, and nesting occurs on riverbanks, beaches and other sandy areas. Females dig egg chambers that may contain nearly 80 feet of interconnected tunnels and multiple entrances and lay clutches of anywhere from 14-76 eggs. Green iguanas can live up to 10 years in the wild and 19 years in captivity.


It is important to retain the natural substrate composition. Many people either dump sand to create a beach area, or clear the natural vegetation. Sand beaches are vulnerable to erosion and kill the vegetation underneath. The sand is easily washed away by receding wave action. If a sandy surface is desired, it should be placed well away from the zone affected by wave action, with a wide vegetated buffer strip. Removing the native vegetation, and too many fallen logs and branches both increases the rate of erosion and harms the waterbody's ecosystem. The roots from the vegetation hold the shore together and provide food and shelter for aquatic mammals, birds, turtles and insects.


Structure and functions of all types of coastal ecosystems will continue to be at moderate to high risk under the RCP2.6 scenario (medium confidence) and will face high to very high risk under the RCP8.5 scenario (high confidence) by 2100. Seagrass meadows (high confidence) and kelp forests (high confidence) will face moderate to high risk at temperature above 1.5oC global sea surface warming. Coral reefs will face very high risk at temperatures 1.5C of global sea surface warming (very high confidence). Intertidal rocky shores are also expected to be at very high risk (transition above 3C) under the RCP8.5 scenario (medium confidence). These ecosystems have low to moderate adaptive capacity, as they are highly sensitive to ocean temperatures and acidification. The ecosystems with moderate to high risk (transition above 1.8C) under future emissions scenarios are mangrove forests, sandy beaches, estuaries and salt marshes (medium confidence). Estuaries and sandy beaches are subject to highly dynamic hydrological and geomorphological processes, giving them more natural adaptive capacity to climate hazards. In these systems, sediment relocation, soil accretion and landward expansion of vegetation may initially mitigate against flooding and habitat loss, but salt marshes in particular will be at very high risk in the context of SLR and extreme climate-driven erosion under RCP8.5. 5.3, Figure 5.16


Near-shore coastal ecosystems are classified by their geomorphological structure (e.g., estuaries, sandy beaches and rocky shores) or foundation species (e.g., salt marshes, seagrass meadows, mangrove forests, coral reefs and kelp forests). All these coastal ecosystems are threatened to a varying degree by SLR (SLR), warming, acidification, deoxygenation and extreme weather events (Sections 5.3.1 to 5.3.7). Unlike the open ocean where detection and attribution of climate driven-physical and chemical changes are robust (Section 5.2.2), coastal ecosystems display regional complexity that can render the conclusive detection and attribution of climate effects uncertain. The hydrological complexity of coastal ecosystems that affects their biota is driven by the interactions between the land (e.g., river and groundwater discharges), the sea (e.g., circulation, tides) (Section 5.2.2.2.3) and seabed structures and substrates (Sharples et al., 2017; Chen et al., 2018; Laurent et al., 2018; Zahid et al., 2018).


Worldwide, sandy beaches show vegetation transformations caused by erosion following locally severe wave events (Castelle et al., 2017997; Delgado-Fernandez et al., 2019998; Zinnert et al., 2019999) (Table SM5.7). The original dense vegetation is replaced by sparser vegetation (Zinnert et al., 20191000) and has a generally slow recovery (multiple years to decades) (Castelle et al., 20171001). In some instances, the changes persist over decades, resulting in a regime shift in the beach morphology (Kuriyama and Yanagishima, 20181002). Such changes in vegetation and beach morphology in response to local disturbances were also related to shifts in the associated fauna composition (Carcedo et al., 20171003; Delgado-Fernandez et al., 20191004). Direct attribution of these observed events to climate change is not available despite early evidence (since the 1970s) and an emerging literature (Section 4.3.3.1, Table SM5.7).


Sandy beaches show similar patterns of biogeographical shifts following warming, with increased dominance of species more tolerant to higher temperatures, as observed in other ocean ecosystems (Section 5.2.3.1.1, Table SM5.7). Examples of these observed shifts in abundance and distribution of benthic fauna in sandy beaches are found in the Pacific and Atlantic coasts of North and South America, and in Australia, including increased mortality of clam populations close to their upper temperature limits with low population recovery (Orlando et al., 20191005), and poleward expansion of crabs since the 1980s that were related to warming (Schoeman et al., 20151006) (Table SM5.7). Also, mass mortalities of beach clams have occurred during warm phases of El Niño events (Orlando et al., 20191007)(Table SM5.7), parasite infestations on dense populations (Vázquez et al., 20161008) and high wave exposure (Turra et al., 20161009).


Human disturbances have caused coastal squeeze and morphological changes in sandy beaches (Martínez et al., 20171010; Rêgo et al., 20181011; Delgado-Fernandez et al., 20191012). Along with SLR and climate-driven intensification of waves and offshore winds, these hazards have increased erosion rates suggesting a reduced resilience due to insufficient sediment supply and accretion capacity (Castelle et al., 20171013; Houser et al., 20181014; Kuriyama and Yanagishima, 20181015). Narrow sandy beaches such as those in south California (Vitousek et al., 20171016) or central Chile (Martínez et al., 20171017) are particularly vulnerable to climate hazards when combined with human disturbances and where landward retreat of beach profile and benthic organisms is constrained due to increasing urbanisation (Hubbard et al., 20141018) (Section 4.3.2.3).


Notwithstanding the uncertainty in projecting future interactions of SLR with other natural and human impacts on sandy shorelines (Le Cozannet et al., 2019; Orlando et al., 20191019), they are expected to continue to reduce their area and change their topography due to SLR and increased extreme climatic erosive events. This will be especially important in low-lying coastal areas with high population and building densities (medium confidence, SM 4.2). Megafauna that use sandy beaches during vulnerable parts of their life cycles could be particularly impacted (Laloë et al., 20171020). For example, the modelled incubation temperatures of green turtles have increased by 1C since the mid-1970s, resulting in an average 20% increase in the proportion of female hatchlings over this period (Patrício et al., 20191021). By 2100, global temperatures will approach lethal levels for incubation in existing nesting sites, and hatchling success is expected to drop to 32% under RCP8.5 scenario, with 93% of the hatchlings expected to be female (76% under RCP4.5). A possible microhabitat adaptation such as shadowed vegetated areas, however, could allow for continued male production throughout the 21st century (Patrício et al., 20191022). In addition, a projected global mean SLR of 1.2 m under the upper likely range of RCP8.5 by 2100 implies a loss of 59% and 67% in the present nesting area of the green turtle and the loggerhead respectively in the Mediterranean (Varela et al., 20191023), and a loss of 43% in the nesting area of green turtles in West Africa (Patrício et al., 20191024). Moreover, benthic crustaceans of sandy beaches, including isopods, crabs and amphipods, generally follow the temperature-body size gradient in which body size decreases towards warmer lower-latitude regions (Jaramillo et al., 20171025). Assuming that the physiological underpinning of the relationship between body size and temperature can be applied to warming (see Section 5.2.2, medium confidence), the body size of sandy beach crustaceans is expected to decrease under warming (low evidence, medium agreement). 041b061a72
