Special Issue Information

Dear Colleagues,

In an ever changing Earth, the coastal settings and continental shelves represent the dynamic transition zone between the land and ocean, including a variety of geomorphic features as well as rich living and non-living natural resources. They are also extremely important environments that enhance prosperity in many societies by integrating ecosystem services and a plethora of activities (e.g., agriculture, tourism, fishing, aquaculture, maritime transport, exploitation of natural resources, development of submarine infrastructure). In addition, and most importantly, shelf seas have been contributing, throughout the geologic time, to climate amelioration via the absorption of the excess amounts of the climatically-crucial greenhouse gases, while they accommodate processes that have been affecting the stratigraphy of the deep-water depositional systems.

The successful completion of the first volume of the Special Issue "Coastal and Continental Shelf Dynamics in a Changing Climate" included a diversity of studies within the context of climate variability, dealing with the following topics: (i) geomorphologic evolution and local and regional paleoclimate reconstructions of coastal settings in the Mediterranean Basin, which is a hotspot of global climate changes; (ii) coastal vulnerability due to the acceleration of the present sea level rise; (iii) thermal maturity of the pre-Messinian sediment strata in the Mediterranean Ridge occurring below the evaporite giant formed during the Messinian Salinity Crisis (triggered by a combination of tectonics and global climate change); (iv) compounding effects of sea level rise and fluvial flooding; (v) iron biochemistry in Antarctica affected by the circumpolar deep water current in the Southern Ocean; (vi) increase in salinization in river estuaries and unconfined coastal aquifers due to the enhancement of the current sea level rise rate; and, finally, (vii) need for an effective implementation of the Marine Strategy Framework Directive (MSFD) and Maritime Spatial Planning Directive (MSPD) for the amelioration of the effects of the current climate trend.

Now we offer a second volume focusing on the degree of impacts of the present climate trend on specific coastal environments (e.g., beach zones, lagoons, coastal dunes, coral reefs, estuaries, river deltas) and their mitigation in terms of adaptation, building capacity (through monitoring and remote sensing tools) and assessment of their social and economic consequences. Further, the second volume has the ambition to address issues related to marine biology such as invasion of alien species, acidification and eutrophication phenomena. Finally, submissions concerning the reconstruction of paleoclimate and paleoceanographic conditions throughout the world are highly recommended, since the understanding of past climate can provide vital clues for a reliable assessment of the future global warming and its effects on ecosystems and human prosperity.

Globally, deep-water reservoir systems are comprised of a variety of traps. Lateral and downdip trapping features include sand pinch-outs, truncation against salt or shale diapirs, and monoclinal dip or faulting with any combination of trapping designs; the potential for massive hydrocarbon accumulations exists, representing significant exploration prospects across the planet. However, deep-water turbidites and submarine fans are two different types of traps, which are developed along the upslope and the basin floor fans. Among these two traps, the basin floor fans are the most prolific traps as they are not influenced by sea-level rise, which distorts the seismic signals, and hence provides ambiguous seismic signatures to predict them as hydrocarbon-bearing zones for future explorations. Therefore, the deep-water channel-levee sand systems and basin floor fans sandstone define economically viable stratigraphic plays. The subsurface variability is significant, and hence, characterizing the thick (porous) channelized-basin floor fans reservoir is a challenge for the exploitation of hydrocarbons. This study aims to develop seismic-based attributes and wedge modeling tools to accurately resolve and characterize the porous and gas-bearing reservoirs using high-resolution seismic-based profiles, in SW Pakistan. The reflection strength slices better delineate the geomorphology of sand-filled channelized-basin floor fans as compared to the instant frequency magnitudes. This stratigraphic prospect has an area of 1180 km2. The sweetness magnitudes predict the thickness of channelized-basin floor fans as 33 m, faults, and porous lithofacies that complete a vital petroleum system. The wedge modeling also acts as a direct hydrocarbon indicator (DHI) and, hence, should be incorporated into conventional stratigraphic exploration schemes for de-risking stratigraphic prospects. The wedge model resolves a 26-m thick hydrocarbon-bearing channelized-basin floor fans lens with a lateral distribution of ~64 km. Therefore, this wedge model provides ~75% correlation of the thickness of the LSL as measured by sweetness magnitudes. The thickness of shale that serves as the top seal is 930 m, the lateral mud-filled canyons are 1190 m, and the thick bottom seal is ~10 m, which provides evidence for the presence of a vibrant petroleum play. Hence, their reveals bright opportunities to exploit the economically vibrant stratigraphic scheme inside the OIB and other similar global depositional systems. Full article

The main objective of the present paper is to achieve the simulation of the long-term (e.g., annual) morphological evolution (bathymetry and shoreline) of a coastal area (Mastichari beach, Greece) due to wind-generated waves in an accurate and cost-effective way. For this purpose, wave climate schematization techniques are adopted in order to reduce the computational effort without losing or distorting the crucial information. Referring to the current practice, the wave chronology is not considered in detail in these acceleration techniques, and therefore, sea bottom and shoreline evolution are not estimated as a function of time. To fill this gap, a novel and easy-to-use chronology-based wave input reduction method is developed to produce representative wave time series of different intensities and durations. The performance of all the applied techniques in the present study is evaluated, and a comparative analysis is conducted. It is shown that the new chronology-based wave input reduction method can achieve a model run-time reduction of about 70%, while at the same time, it provides satisfactorily accurate results. In general, this research could be useful for coastal engineering studies and coastal zone monitoring, and thus, it would be a valuable tool for coastal engineers and marine scientists. Full article

The long-term trend and interannual variation of ocean heat content (OHC) in the Bohai Sea, Yellow Sea, and East China Sea (BYECS) were examined using 27 years (1993–2019) of daily reanalysis data from the Japan Coastal Ocean Predictability Experiment 2 (JCOPE2M). The annual mean OHC was 4.25 × 1021 J, with a linear warming rate of 0.13 W m−2 with a confidence level of 95%. The spatial distributions for the annual and linear trends of OHC in the BYECS were inhomogeneous, and a considerable quantity of heat was stored on the outer shelf. The warming rate was considerably elevated in the areas northeast of Taiwan and southwest of Kyushu, showing a rate greater than that of the Pacific and global oceans by a factor of 4–5. Heat budget analysis indicated that the Taiwan Strait (TAS) is the dominant source of heat for the BYECS. The mechanisms of the OHC interannual variation in the outer and inner shelves varied. On the outer shelf, the OHC interannual variation was dependent on the Kuroshio onshore intrusion, while on the inner shelf, the OHC interannual variation was related to the variation in air-sea heat flux. The rapid warming in the outer shelf corresponded to the increasing trends of heat transport across northeast Taiwan and southwest Kyushu, which were dominated by the temporal variation of current velocity.

In this study, we analyze sea surface height referenced against the WGS84 ellipsoid at the Hon Dau tidal gauge station (Hai Phong, Vietnam), in front of the Red River Delta, between 1961 and 2020. The annual sea level varied from 165.23 cm to 206.06 cm in this period (+20.28 cm over 60 years). The average water level was 190.87 cm for 60 years, with higher annual values in recent years, especially from 2016 to the present (above 201.5 cm). The Mann–Kendall (MK) test with Sen’s slope estimator and Şen’s innovative trend analysis (ITA) were applied and compared to estimate the sea level rise. These methods showed complete agreement among tests with significant rising trends of about 3.38 mm/year with the MK test and 3.08 mm/year with the ITA method for 1961–2020. During the last 20 years (2001–2020), the mean sea level increased about 7.16 mm/year (MK test and Sen’s slope), 7.38 mm/year (ITA method), and around twice higher than the rate of the region and globally. The MK test and ITA method provided similar results for periods: 1961–2020, 1961–1980, and 2001–2020, with relatively stable monotonic related trend conditions. For the period 1981–2000, with a more nonmonotonic trend, the MK test and ITA method provided different trends and allowed to illustrate the specificity of each method. Full article
