  • First MedCPR tow

    GACS is pleased to report that the first tow of the new Mediterranean CPR survey successfully took place this month on a route from Larnaca, Cyprus, to Haifa, Israel, on 21st October. The second tow is scheduled to take place in November. Congratulations to Rana Abu Alhaija and the MedCPR team!

  • Chair of GACS receives SCAR Award

    The Chair of GACS Dr Graham Hosie has received one of the inaugural SCAR (Scientific Committee on Antarctic Research) Visiting Professor awards.

  • GACS has become an affiliated programme of the Scientific Committee on Ocean Research (SCOR)

    The Southern Ocean Observing System (SOOS) has become an official stakeholder of GACS. SOOS is an international initiative sponsored by SCAR and SCOR to “enhance, coordinate and expand the strategic observations of the Southern Ocean that are required to address key scientific issues and societal challenges.” The CPR is an important component of SOOS’ observational network

  • 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    Imagine looking at your garden one morning and finding that the grass had suddenly been replaced by bushes.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 (right)



GACS is short for the Global Alliance of Continuous Plankton Recorder Surveys, which is an international scientific organisation 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 surveys".

The GACS Partners in Plymouth, UK at the first GACS Workshop, September 2013.

GACS has a number of specific aims, which include:

  • to develop a global Continuous Plankton Recorder (CPR) database
  • to produce a regular Ecological Status Report for global plankton biodiversity
  • to ensure that common standards and methodologies are maintained
  • to provide an interface for plankton biodiversity with other global ocean observation programmes
  • to set up and maintain a website for publicity and data access
  • to facilitate new CPR surveys and develop capacity building procedures
  • to facilitate secondments of CPR scientists between GACS institutions.

To learn more about GACS, the Continuous Plankton Recorder and its Partners, please, check out the About GACS pages, and if you have an enquiry or want to get in touch with GACS, please, see the Contact Us page.

This website is a work in progress and will be updated periodically.  We aim to have some initial data products using GACS data online by May 2012; please, check regularly for news and updates.
