Chemoautotrophic marine bacteria from the SUP05 clade of marine gammaproteobacteria often dominate low-oxygen waters in upwelling regions, fjords, and hydrothermal systems. Here, we announce the complete genome sequence of "Candidatus Thioglobus autotrophica" strain EF1, the first cultured chemoautotrophic representative from the SUP05 clade.

The interaction of hydrodynamics and biology is a highly suitable subject for coupled biophysical modelling of particle transport. This has been worked on by coupling hydrodynamic models with biological particle models of sea lice dispersal in the Loch Torridon system, a small fjord in northwest Scotland. This system has been the subject of studies of larval sea lice distribution dating back to...

[1] The recent loss of Jakobshavn Isbræ’s extensive floating ice tongue has been accompanied by a change in near terminus behavior. Calving currently occurs primarily in summer from a grounded terminus, involves the detachment and overturning of several icebergs within 30–60 min, and produces long-lasting and far-reaching ocean waves and seismic signals, including ‘‘glacial earthquakes’’. Calvi...

A total of 2198 silver eels were Carlin-tagged and released at two sheltered and one exposed site in the western Baltic Sea. A total of 547 tagged silver eels were recaptured, corresponding to recoverv rates from 19 to 38% at the different sites. The majoritv of the recaptured silver cds was reporred from wirhin a radius of 20 km and within a period of less than 16 days after release. There was...

The current study describes the taxonomic and functional composition of metagenomic sequences obtained from a filamentous microbial mat isolated from the Comau fjord, located in the northernmost part of the Chilean Patagonia. The taxonomic composition of the microbial community showed a high proportion of members of the Gammaproteobacteria, including a high number of sequences that were recruit...

The process of biotope occupation by the anenome Metridium sen~le in the absence of pelagic larvae has been investigated by an in situ monitoring experiment lasting from July 1981 to April 1982. This process is composed of several behavioral phases: dispersion of the anemones on the new substrate by h ~ g h locomotory activity, colonization of the 'chosen' habltat by intensive asexual reproduct...

We used a terrestrial radar interferometer (TRI) at Helheim Glacier, Greenland, in August 2013, to study the effects of tidal forcing on the terminal zone of this tidewater glacier. During our study period, the glacier velocity was up to 25md. Our measurements show that the glacier moves out of phase with the semi-diurnal tides and the densely packed melange in the fjord. Here detrended glacier...

The diversity and cold-active hydrolytic enzymes of culturable bacteria associated with sandy sediment from Nella Fjord, Eastern Antarctica (69°22'6″ S, 76°21'45″ E) was investigated. A total of 33 aerobic heterotrophic bacterial strains were isolated at 4 °C. These bacterial isolates could be sorted into 18 phylotypes based on the 16S rRNA gene sequence belonging to four phyla, namely Alphapro...

Many marine protists form resting stages that can remain viable in coastal sediments for several decades. Their long-term survival offers the possibility to explore the impact of changes in environmental conditions on population dynamics over multidecadal time scales. Resting stages of the phototrophic dinoflagellate Pentapharsodinium dalei were isolated and germinated from five layers in dated...

The density and spatial distribution of benthic viruses and prokaryotes in relation to biotic and abiotic factors were investigated in sediment cores collected in Hornsund, a permanently cold fjord on the West coast of Svalbard, Norway. The cores were obtained from the mouth of the fjord to the central basin, along a longitudinal transect. The results of our analyses showed lower densities of v...
