Trichodesmium is a globally important marine diazotroph that accounts for approximately 60-80% of marine biological N2 fixation and as such plays a key role in marine N and C...

Calcified marine organisms typically experience increased oxidative stress and changes in mineralization in response to ocean acidification and warming conditions. These effects...

Persistent organic pollutants (POPs) are known to converge into the ocean and accumulate in the sediment, posing great threats to marine organisms such as the sessile bottom...

Oceanic uptake of CO2 from the atmosphere has significantly reduced surface seawater pH and altered the carbonate chemistry within, leading to global Ocean Acidification (OA)....

Physiological responses to temperature are known to be a major determinant of species distributions and can dictate the sensitivity of populations to global warming. In...

A projection of larval dispersal patterns of Atlantic cold seep mussels Gigantidas childressi, G. mauritanicus, Bathymodiolus heckerae and B. boomerang was carried out for the...

These data aim at evaluating the hypothesis of long-distance dispersal across the North Atlantic and the Equatorial Atlantic belt for the cold seep mussels Gigantidas...

The data consist of hourly observations of sedimentation impacts located approximately 31 m southwest of the drilling location, including measurements of proxies of suspended...

Microfibre abundance in aggregates were defined by counting microfibres observed in images of aggregates and then extrapolated per mm of the aggregate imaged. Microfiber...

Size, volume and settling velocity were measured by making a recording of the rotating tanks using a commercial digital single-lens reflex camera (Canon) equipped with a...

Micro growth of freshwater bivalve (Paxyodon syrmatophorus) with marking fluorochrome calcein to validate the assumption of ring formation grown in the Maratauira river,...

*Values were modelled analogue to those for samples taken at elevated temperatures for visual comparison.

Here we present taxon-specific apparent growth rate data obtained from high-pressure liquid chromatography (HPLC) pigment and flow cytometry (FCM) analisis of initial (T0) and...

Survival rates of major grazer taxa (Gammarus sp., Idotea, sp., Littorina sp. and Rissoa sp.) exposed to upwelling-induced hypoxia. Treatments: ocean warming=i.e. warming levels...

Microfouling (expressed as cell numbers per cm2) by bacteria and diatoms in response to warming (+0, 2 and 4°C) and upwelling during upwelling event 3. Treatments: ocean...

Macrofouling accumulation on settlement panels (assessed as % cover) over the experimental period in response to warming and/or upwelling. Treatments: ocean warming=i.e. warming...

A mature Salpa thompsoni oozooid was collected using a so-called salp-net (1 m diameter ring net with 202 µm mesh fitted with a 30 litre non-filtering cod-end) at the Chatham...

In a field study (2007-2009) on Sapelo Island, GA, USA (31°27' N, 81°15' W), we incubated two contrasting detritus types in three distinct habitat types in coastal Georgia to...

Anthropogenic inputs of carbon dioxide in the atmosphere are driving ocean warming and acidification. The potential threat represented by these changes for marine species could...

These data are the first observations of Arctic winter microbial activity under sea ice in a west Greenland fjord (Lillefjord, 70°30'N 50°40'W), and are based on changes in...
