Candida albicans counts were assessed in Mediterranean sea water using MCA media. From 116 seawater samples C. albicans was detected in 22 samples of 100 ml sea water. In sixteen samples only one colony, and in six samples two colonies, of C. albicans were found and the fungus does not appear to be an important contaminant of sea water.

The amount of methane released to the atmosphere from the Nord Stream subsea pipeline leaks remains uncertain, as reflected in a wide range of estimates. A lack of information regarding the temporal variation in atmospheric emissions has made it challenging to reconcile pipeline volumetric (bottom-up) estimates with measurement-based (top-down) estimates. Here we simulate pipeline rupture emission rates and integrate these with methane dissolution and sea-surface outgassing estimates to model the evolution of atmospheric emissions from the leaks.

Foraminifera are ubiquitous marine protists that intracellularly accumulate phosphate, an important macronutrient in marine ecosystems and in fertilizer potentially leaked into the ocean. Intracellular phosphate concentrations can be 100-1,000 times higher than in the surrounding water. Here we show that phosphate storage in foraminifera is widespread, from tidal flats to the deep sea.

The Gulf of Maine holds significant ecological and economic value for fisheries and communities in north-eastern North America. However, there is apprehension regarding its vulnerability to the effects of increasing atmospheric CO. Substantial recent warming and the inflow of low alkalinity waters into the Gulf of Maine have raised concerns about the impact of ocean acidification on resident marine calcifiers (e.

The Nord Stream pipeline leaks on 26 September 2022 released 465 ± 20 kt of methane into the atmosphere, which is the largest recorded transient anthropogenic methane emission event. While most of the gas escaped directly to the atmosphere, a fraction dissolved in the water. So far, studies on the fate of this dissolved methane rely on pipeline volumetric estimates or spatially sparse concentration measurements and ocean models.

To fully understand variation in phytoplankton community structure in the Eastern Indian Ocean (EIO), two research cruises were carried out during September-November 2020, and March-May 2021. The phytoplankton community in the EIO was mainly composed of cyanobacteria and diatoms in 2020, cyanobacteria in 2021. Trichodesmium thiebaultii was the dominant specie in both years.
