At the southern tip of South America, evidence of shellfish toxicity has been recorded in the accounts of early explorers and shipwreck survivors since the late 16th Century. Blooms of the toxic dinoflagellate Alexandrium catenella were described in the western Magellan Strait in the early 1970s and have since shown a northward progression through ...

Investigating organic compounds in marine sediments can potentially unlock a wealth of new information in these climate archives. Here, we present pilot study results of organic geochemical features of long-chain n-alkanes and alkenones and individual carbon isotope ratios of long-chain n-alkanes from a newly collected, approximately 8 m long, loca...

Here, we describe three endosymbiotic bacterial strains isolated from the gills of the shipworm, Bankia setacea (Teredinidae: Bivalvia). These strains, designated as Bs08T, Bs12T and Bsc2T, are Gram-stain-negative, microaerobic, gammaproteobacteria that grow on cellulose and a variety of substrates derived from lignocellulose. Phenotypic characteri...

Atmospheric deposition is the dominant pathway for the loading of exogenous nitrogen (N) to open ocean. Here, rainwater samples were collected from 31 stations in the equatorial East Indian Ocean (EIO) and West Pacific Ocean (WPO) to explore the spatial variability of N species, potential sources, and related ecological influences. Among two oceans...

In 1842, Darwin identified three types of reefs: fringing reefs, which are directly attached to volcanic islands; barrier reefs, which are separated from volcanic islands by lagoons; and ring reefs, which enclose only a lagoon and are defined as atolls. Moreover, he linked these reef types through an evolutionary model in which an atoll is the logi...

The high-resolution expendable bathythermograph (HR-XBT) network measures temperature down to approximately 800 m along fixed transects. In comparison, Argo floats are distributed throughout the global ocean and measure temperature and salinity down to approximately 2000 m. Over the 2004-2019 period, the HR-XBT network tended to have a greater samp...

Abstract—Hydrogenetic Fe–Mn crusts in the ocean are enriched in platinum but do not accumulate palladium. The mechanism of platinum input into the crusts remains debatable. There is even less data on ruthenium and iridium. In this article, the distribution of platinum group elements (Pd, Ru, Ir, Pt) in ferromanganese crusts of the Detroit guyot (No...

Abstracthe Paleocene–Eocene sedimentary complex is most widely developed among the sedimentary cover deposits of the Magellan Seamounts. It is composed of pelagic (nanoforaminiferal) and reef limestones, edaphogenic breccias and volcanoclastic rocks. The most widespread pelagic limestones form narrow (0.5–1.5 km) and extensive (up to 20 km) ribbon-...

AbstractBased on the NOAA climate datasets, trends, regional features, and possible causal relationships of interannual variations in water temperature on the surface (SST) and in the upper 750-meter layer of the subarctic Pacific with variations in the fields of air temperature, air pressure, wind, and climate indices over the past four decades ar...

The paper presents spatial analysis of the geological settings and topographic structure of the Pacific Ocean by Generic Mapping Tools (GMT). Its tectonic and geomorphic features have complex character and include, among others, trenches, ridges, East Pacific Rise, basins, fracture zones, rifts, rises, fault systems. Such topographic complexity res...
