Long-term sea surface temperature (SST) warming trends are far from being homogeneous, especially when coastal and ocean locations are compared. Using data from NOAA's AVHRR OISST, we have analyzed sea surface temperature trends over the period 1982-2015 at around 3500 worldwide coastal points and their oceanic counterparts with a spatial resolution of 0.25 arc-degrees. Significant warming was observed at most locations although with important differences between oceanic and coastal points. This is especially patent for upwelling regions, where 92% of the coastal locations showed lower warming trends than at neighboring ocean locations. This result strongly suggests that upwelling has the potential to buffer the effects of global warming nearshore, with wide oceanographic, climatic, and biogeographic implications.

Although the surface micro-ornamentation of the scales within the skin of snakes has been the subject of many previous studies, there has been little work done on the spectacle, a protective (keratinised) goggle separated from the underlying cornea by a sub-spectacular space. The surface ultrastructure of the "Oberhäutchen" of the spectacle is examined in nine species of snakes (five aquatic and four terrestrial) using light and electron microscopy, micro-computed tomography and gel-based profilometry. Significant topographic differences in cell size (increases of between 5.

This study investigates the vertical profiles, pollution status and ecological risks of heavy metal(loid)s contamination in three sediment cores (N21, N03, and 38002) from the North Yellow Sea (NYS), with a focus on the influence of grain size effects on sedimentary profiles. The results revealed distinct vertical distribution patterns of heavy metal(loid)s content among the three sediment cores. Enrichment Factor (EF) and Geo-accumulation Index (I) assessments identified Sb as significantly enriched, indicating anthropogenic influence, whereas Co, Cr, Cu, Ni, and Zn primarily originated from natural weathering.

Sri Lanka is uniquely situated at the junction of the Bay of Bengal (BOB) and the Arabian Sea (AS), where phytoplankton community may be strongly influenced by ocean dynamical processes, particularly mesoscale eddies and the East Indian Coastal Current (EICC). Here, to explore these regulatory mechanisms, phytoplankton and physicochemical parameters were collected from the top 200 m water column in the eastern and southern seas of Sri Lanka during the winter monsoon. Results showed higher concentrations of nutrients and phytoplankton abundance within the regions affected by EICC and cyclonic eddy (CE) compared to anticyclonic eddy (ACE).

Hypothesis: Gas hydrate formation in sediments is influenced by the availability of gas-water interfacial areas, which governs gas-water interactions. The surface wettability of sediment particles is expected to affect the spatial distribution of water within the pore space, thereby altering the extent of gas-liquid contact. Consequently, by tuning the wettability heterogeneity of the sediment, the spatial distribution of pore water can be regulated, which in turn influences the gas-water interactions and the kinetics of gas hydrate formation.

Sea surface temperature of the Red Sea has increased by up to 0.45 °C per decade over the last 30 years, and coral bleaching events are becoming more frequent. A reef bleaching event was observed in October 2020, whereby some parts of the Red Sea experienced more than 12 °C-weeks.
