Scientists of GEOMAR Helmholtz Centre for Ocean Research Kiel used so - called «indoor mesocosms» to mimic the future ocean in their laboratories: They transferred the natural
plankton community from the Kiel Fjord into twelve 1400 - liter tanks and brought them to two different temperatures and two different carbon dioxide concentrations.
In parallel, we use high throughput sequencing methods to obtain both deep phylogenetic rDNA / rRNA tag data and metagenomic and metatranscriptomic functional profiles from size fractions covering the entire
plankton community from viruses to fish larvae (Figure 2B and 2C).
Not exact matches
Nearly all are part of a drifting
community of organisms called
plankton, a term derived
from the Greek word for wanderer.
But we wanted to observe the natural development of the
plankton ecosystem
from the first productivity in late winter until summer, closely monitor the succession of the
plankton communities and follow how effects of ocean acidification are transmitted
from one generation to the next,» Riebesell explains.
Thirty - five scientists
from twelve countries deployed these «giant test tubes» in the Kongsfjord off Ny - Ålesund to investigate how ocean acidification affects the
plankton community in the Arctic.
In this study we combined results
from various in - situ mesocosm studies in two different ocean regions (Arctic and temperate waters) to reveal general patterns of
plankton community shifts in response to OA and how these changes are modulated by inorganic nutrient availability.
In an experiment with organisms
from the Kiel Fjord, a team of biologists
from GEOMAR Helmholtz Centre for Ocean Research Kiel demonstrated for the first time, that ocean acidification and rising water temperatures harms the fatty acid composition of copepods in the natural
plankton community.
Bridlington, Whitby, and other English coastal towns have long depended on the North Sea fishery for food and income.2 But global warming is affecting
plankton and changing the marine food chain, compounding the pressures of overfishing.3 The resulting disruption of the ecosystem could damage the fishing industry and hurt North Sea coastal
communities from the United Kingdom to Scandinavia.
