The study of vertical migrations in aquatic organisms has a long and colourful history, much
of it to do with the effects of changing sampling technology on our understanding of the …

Exploring climate and anthropogenic impacts on marine ecosystems requires an
understanding of how trophic components interact. However, integrative end-to-end …

Methylmercury (MeHg) concentrations can increase by 100 000 times between seawater
and marine phytoplankton, but levels vary across sites. To better understand how ecosystem …

Even at low concentrations in the environment, mercury has the potential to biomagnify in
food chains and reaches levels of concern in apex predators. The aim of this study was to …

Temporal variability in the distribution and abundance of North Atlantic right whales
Eubalaena glacialis and their copepod prey, late-stage Calanus finmarchicus, was …

Concentrations of seven polychlorinated biphenyls (PCBs), hexachlorobenzene (HCB), and
twelve polycyclic aromatic hydrocarbons (PAHs) were examined in plankton collected in …

Small offshore banks may be sites of intense feeding by upper trophic level predators. We
studied the distribution of cetaceans, seabirds, pelagic fish, euphausiids and zooplankton …

The diets of krill and amphipods were examined using light microscopy on field-collected
specimens from 2004 to 2005 from the Marginal Ice Zone of the northwestern Barents Sea …

Different krill species have a pivotal position in many marine food webs by both preying
upon several trophic levels and being forage species for consumers. Within these food …

A macro-zooplankton study from 1996 was repeated in 2006 and focused on euphausiid
species as indicators of advection and warming effects in Kongsfjorden, West Spitsbergen …
