Abstract. Due to low calcium carbonate saturation states, and winter mixing that brings anthropogenic carbon the deep ocean, Nordic Seas their cold-water corals are vulnerable ocean acidification. Here, we present a detailed investigation of changes in pH aragonite from preindustrial times 2100, by using situ observations, gridded climatological data, projections for three different future scen...

The life spans of demersal species of fishes occurring in deep-waters are much longer and their potential growth rates much lower than those of related shallow water species. As a result, deep-sea demersal fish species are more vulnerable to exploitation. This is because low growth rates relative to the available market discount rate for capital makes it desirable for fishing firms to mine, rat...

The focus of this study is the assessment of the main range and geophysical corrections needed to derive accurate sea level time series from satellite altimetry in the Indonesia seas, the ultimate aim being the determination of sea level trend for this region. Due to its island nature, this is an area of large complexity for altimetric studies, a true laboratory for coastal altimetry. For this ...

Variation in zooid size within colonies of fossil cheilostome bryozoans is presented as a potential source of information on palaeoseasonality. We base our approach on the inverse relationship between temperature and zooid size in bryozoans, and analyse the mean intracolonial coefficient of variation (CV ) in zooid length, zooid width and zooid area ( length×width) in a number of Recent bryozoa...

Glacial cycles of the Quaternary have heavily influenced the demographic history of various species. To test the evolutionary impact of palaeo-geologic and climatic events on the demographic history of marine taxa from the coastal Western Pacific, we investigated the population structure and demographic history of two economically important fish (Trichiurus japonicus and T. nanhaiensis) that in...

by Pavel Povinec, Scott Fowler, and Murdoch Baxter I he Chernobyl nuclear accident in April 1986 had a significant impact on both the terrestrial and marine environments. The total activity of the nuclear debris released was so high (1-2.10 becquerel) that the radioactive fallout distributed widely after the accident actually dominated anthropogenic environmental levels in various parts of the ...

An ecosystem modelling approach was used to understand and assess the Mediterranean marine ecosystem structure and function as a whole. In particular, 2 food web models for the 1950s and 2000s were built to investigate: (1) the main structural and functional characteristics of the Mediterranean food web during these 2 time periods; (2) the key species/functional groups and interactions; (3) the...

Ribosomal RNA internal transcribed spacer-1 (ITS1) metabarcoding was used to investigate the distribution patterns of fungal communities and the factors influencing these patterns in subtropical Chinese seas, including the southern and northern Yellow Sea and the Bohai Sea. These seas were found to harbor high levels of fungal diversity, with 816 operational taxonomic units (OTUs) that span 130...

The ability to protrude the jaws and capture elusive prey is a hallmark of fish evolution. New analyses provide insight into how jaw protrusion changed predator-prey relationships and fueled species diversification in ancient seas.
