Zooplankton Run for Life

[…] “mass sinking of zooplankton from the surface waters and accumulation at a depth of ∼50 m occurs every 29.5 days in winter, coincident with the periods of full moon. 52 more words


Microplastic pollution in the Greenland Sea: Background levels and selective contamination of planktivorous diving seabirds

Microplastics have been reported everywhere around the globe. With very limited human activities, the Arctic is distant from major sources of microplastics. However, microplastic ingestions have been found in several Arctic marine predators, confirming their presence in this region. 275 more words


Metabolic responses of the North Pacific krill, Euphausia pacifica, to short- and long-term pCO2 exposure

While ocean acidification is likely to have major effects on many marine organisms, those species that regularly experience variable pCO2 environments may be more tolerant of future predicted changes in ocean chemistry. 235 more words


A data-model synthesis to explain variability in calcification observed during a CO2 perturbation mesocosm experiment

A series of studies were conducted during the last two decades to investigate effects of ocean acidification (OA) on phytoplankton physiology, plankton ecology, and biogeochemical dynamics of marine ecosystems. 306 more words


A first look at factors affecting aragonite compensation depth in the eastern Arabian Sea

Water column measurements suggest shoaling of aragonite saturation depths (ASD) throughout the world oceans, due to increase in greenhouse gas concentration. Past records of aragonite saturation state under different climatic conditions are required to assess the impact of climatic changes on shoaling/deepening of ASD. 269 more words


Ocean acidification reduces demersal zooplankton that reside in tropical coral reefs

The in situ effects of ocean acidification on zooplankton communities remain largely unexplored. Using natural volcanic CO2 seep sites around tropical coral communities, we show a threefold reduction in the biomass of demersal zooplankton in high-CO2 sites compared with sites with ambient CO2. 164 more words


New paper: using X rays to look inside zooplankton resting eggs

Zooplankton dormant eggs are time capsules that can transport offspring to distant futures. However, after decades of study we still don’t know very well how this mechanism has evolved and how it works from a mechanistic point of view. 245 more words
