Global atmospheric carbon levels are continuing to rise from pre-industrial revolution levels. One of the main regulators of global atmospheric carbon levels, and thus climate, is the world's oceans. Unicellular marine cyanobacteria account for a large percent of total marine carbon fixation. We measured chlorophyll-specific ¹⁴C uptake rates (P[superscript b])...

Simulations of past climates require altered
boundary conditions to account for known shifts in the Earth
system. For the Last Glacial Maximum (LGM) and subsequent
deglaciation, the existence of large Northern Hemisphere
ice sheets caused profound changes in surface topography
and albedo. While ice-sheet extent is fairly well
known, numerous...

Assessing the
Bacterioplankton of the SAR11 clade are the most abundant microorganisms in marine systems,
usually representing 25% or more of the total bacterial cells in seawater worldwide. SAR11 is divided
into subclades with distinct spatiotemporal distributions (ecotypes), some of which appear to be
specific to deep water. Here we examine the...

The overflow of deep water from the Nordic seas
into the North Atlantic plays a critical role in global ocean
circulation and climate. Approximately half of this overflow
occurs via the Iceland–Scotland (I–S) overflow, yet the history
of its strength throughout the Holocene (~0–11 700 yr
ago, ka) is poorly...

Improving the understanding of the controls on subsurface stormflow generation has been the goal of numerous experimental and modeling studies. However, the effect of the spatial variability of throughfall on soil moisture patterns and subsurface stormflow (SSF) generation has not yet been studied in detail. The objectives of this study...

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species’ threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that...

Zooplankton fecal pellet flux is a highly variable component of the biological carbon pump. While fecal pellets can comprise 0 to nearly 100% of particulate organic carbon collected in sediment traps, mechanisms for this variability remain poorly understood. Fecal pellet carbon flux is a complex function of several variables. We...

Individual quota (IQ) management systems in commercial marine fisheries are highly diverse, differing in the security, durability and exclusivity of the harvesting privilege and the transferability of quota units. This diversity in the degree of harvest rights may influence the effectiveness of IQ fisheries to meet management objectives. We conducted...
