|Changes in marine dinoflagellate and diatom abundance under climate change
Imagine looking at your garden one morning and finding that the grass had suddenly been replaced by bushes. Far fetched ? You might think so, but changes of this magnitude have recently been reported in the biology of the North Atlantic with a dramatic switch in the prevalence of two groups of microscopic planktonic plants that lie at the base of the food chain....
Welcome to GACS
Marine Phytoplankton (left) and Zooplankton
GACS is short for the Global Alliance of Continuous
Plankton Recorder Surveys, which is an international scientific
partnership that was established in September 2011.
The goal of GACS is "to understand changes in plankton
biodiversity at ocean basin scales through a global network of CPR
The GACS Partners in Plymouth, UK at the first GACS
Workshop, 20-21 September 2011.
GACS has a number of specific aims, which include:
- to develop a global Continuous Plankton Recorder (CPR)
- to produce a regular Ecological Status Report for global
- to ensure that common standards and methodologies are
- to provide an interface for plankton biodiversity with other
global ocean observation programmes
- to set up and maintain a website for publicity and data
- to facilitate new CPR surveys and develop capacity building
- to facilitate secondments of CPR scientists between GACS
