Abstract:
... The present study evaluates ground-based downward surface shortwave radiation (Rₛ) over the coastal region of Alicante (Southeastern Spain). Hourly measurements collected over the eleven-year period 2010-2020 are used. Two weather stations located over the region capital, Alicante, have been selected as representative of urban and suburban typologies. Two additional weather stations far from the c ...
... Spatial synchrony may be tail‐dependent, that is, stronger when populations are abundant than scarce, or vice‐versa. Here, ‘tail‐dependent’ follows from distributions having a lower tail consisting of relatively low values and an upper tail of relatively high values. We present a general theory of how the distribution and correlation structure of an environmental driver translates into tail‐depend ...
... Although subaqueous slopes on active continental margins are subject to a variety of failure styles, their movement mechanisms during earthquakes remain poorly constrained. A primary explanation is that few submarine landslides have been directly sampled for detailed investigation. We have conducted a series of dynamic shear experiments on samples recovered from the base of the Tuaheni Landslide C ...
... Accurate and precise monitoring of the absolute density (i.e., number of fish per area or volume unit) of exploited fish stocks would be strongly advisable for deriving stock status and for designing proper management plans. Moreover, monitoring should be achieved at relevant (i.e., sufficiently large) temporal and spatial scales. This objective is particularly challenging for data-poor fisheries, ...
... Specimens of pink salmon Oncorhynchus gorbuscha (Walbaum, 1792) caught in nearshore waters and rivers of the southeastern coast of Sakhalin Island in 2005–2020 are used as the material for study. The average number of circuli counted on their scales was 36.3 (SD = 2.43), with a range from 33.6 to 38.1 in different year classes. To compare the intercirculus spaces on scales from different fish, all ...
... The Aegean Sea is one of the most contaminated by marine litter (ML) in the World. In this study, the Turkish Aegean Region was evaluated in light of the sources, abundance and composition of ML along Çakalburnu Lagoon coast. Macroscopic ML with > 3 cm was collected and separated into composition and sources categories. ML abundance was calculated by its density in items/m² (Mean ± SD). Beach clea ...
... Fish stocks are being severely depleted, marine habitats are threatened and marine pollution is on the rise due to discarded fishing gear. This equipment is generally from illegal, unreported and unregulated fishing, leading to incidental fishing and sometimes ghost fishing. In this study, data obtained from reports produced by the Environmental Military Police in Santa Catarina, Brazil, on gill n ...

Abstract:
... The invasive Australian pest Glycaspis brimblecombei Moore, 1964 is recorded for the first time in Molise, Liguria and Abruzzo, respectively, based on sampling by the authors in 2014 and observations (photographs) retrieved from the internet which were taken in 2018 and 2021. The records from Molise and Abruzzo are the first ones on the Adriatic side of Italy, east of the Apennines. Furthermore, n ...

... Combining the multi-regional input–output model with complex network technology, based on the provincial scale, this paper systematically describes the characteristics of the spatial network flow and its changing track of embodied carbon emissions among provinces in China from three dimensions of network structure, flow distribution characteristics, and spatial flow characteristics. Furthermore, t ...

... Alkali intrusions of Sakju Complex distributed in the western area, DPR Korea were formed in mid-Proterozoic era. The Zirconium-REE mineralization occurs in Sakju and Ryongpho intrusions of Sakju Complex. Zr and Hf are the typical lithophile elements and always exist together under the closed relation to alkali and acid igneous rock. In our country, Zr and Hf mineral resources are exploited in the ...

Abstract:
... Coastline is an important geographical element of the boundary between ocean and land. Due to the impact of the ocean-land interactions at multiple temporal-spatial scales and the intensified human activities, the waterline of muddy coast is undergoing long-term and continuous dynamic changes. Using traditional remote sensing-based waterline extraction methods, it is difficult to achieve ideal res ...

Abstract:
... Digha is one of the largest sea resorts in eastern India, facing a long history of erosion and has been engineered extensively since 1970s. It extends for 5.45 km along the Medinipur coast, which can be divided into three sectors viz. New Digha, Old Digha and Gangadharpur based on the beach character. The current study aims to identify the erosion–accretion trend of the coast and link it with the ...

Abstract:
... Managed realignment (MR) involves the landward relocation of sea defences to foster the (re)creation of coastal wetlands and achieve nature-based coastal protection. The wider application of MR is impeded by knowledge gaps related to lacking data on its effectiveness under extreme surges and the role of changes in vegetation cover, for example due to sea-level rise. We employ a calibrated and vali ...

... Finless porpoise excluder devices have been developed to prevent bycatch of finless porpoise by stow net in Korea; however, fishermen are hesitant to use them owing to concerns of associated catch losses. To promote their use, we aimed to identify the characteristics of catch losses associated with finless porpoise excluder devices used along the Korean west coast and suggest a strategy to reduce ...

The study was conducted to investigate the effect of spatial variation, alkali treatment and the volume of extractant on yield and gel strength of agar for three Gracilaria species (G. salicornia, G. edulis and G. corticata) collected from the Tanzanian coast (Dar es Salaam, Tanga and Zanzibar). Treated and untreated G. corticata showed the highest yield (27 ± 0.7 % and 26.2 ± 1.3 % for treated an ...

... Increasing trend of number and intensity of the extreme precipitation events in India has been reported in literature. Majority of the Indian weather stations have historical rainfall data recorded at a fixed time (0830 hours) of the day, which could be a limitation for correct estimation of extremes. To overcome this, clock hour correction factor (CHCF) in extreme value analysis (EVA) assumes imp ...

... Machine learning (ML) classifiers provide convenience and accuracy in coastline extraction compared to traditional methods and image processing techniques. In literature, the studies about coastline extraction with machine learning classifiers are not focused adequately on the coast types that affect the process. To eliminate this gap, machine learning classifiers were examined in terms of their a ...

Rip currents are one of the most well-known and risky flows in coastal areas, and given the limitations and difficulties in field data collection, predicting the varied behavior of these flows is of particular importance. In this study, based on the design of the intermediate beaches, the wave and bed parameters in the coastal zone were extracted as dimensionless ratios of Froude number, wave heig ...

When the in-orbit geometric calibration of optical satellite cameras is not performed in a precise or timely manner, optical remote sensing satellite images (ORSSIs) are produced with inaccurate camera parameters. The internal orientation (IO) biases of ORSSIs caused by inaccurate camera parameters show a discontinuous distorted characteristic and cannot be compensated by a simple orientation mode ...
