Variability in phytoplankton pigments at the Antares ChloroGIN time-series stations

ANTARES is a network of eight countries dedicated to study long-term changes in coastal areas around Latin America based on the observation of the temporal variability of eight coastal stations. During the last four years (2012 to 2015) and continuing during 2016, the network was funded by Nippon Foundation with the general objective of strengthening the interaction between NANO and ´ChloroGIN-ANTARES´ networks focusing specially on pigment analysis using HPLC. This objective was accomplished thanks to the collaboration with the Ocean Ecology Laboratory (NASA Goddard Space Flight Center, Greenbelt, Maryland, USA). The importance of this analysis is both (a) its relationship with biogeochemical cycles and (b) the need of data to calibrate and validate mathematical algorithms used to interpret satellite images.


  • To continue the activities that contribute to the strengthening of working relationships among ANTARES stations (and members).
  • To continue the activities of synergy between NANO and ANTARES networks.Contribute to the maintenance of the NANO and ANTARES websites.
  • Work on the data generated during the three previous years of the project and publish the results in an international scientific journal.
  • Prepare printed and hands on material to disseminate the role of the oceans and organizations such as NF-POGO, NANO and ANTARES to society. This material will be distributed among participating countries and each country will be responsible of its dissemination.
  • Put together developments of outreach in each one of the participating centers.
  • Organize a workshop in February 2016 to:- Discuss and interpret the results of the 2012-2014 NANO Regional Project for Latin America; including a comparison of phytoplankton pigment analysis obtained at each center and those provided by NASA.

    – Discuss and interpret the results of the HPLC intercomparison among participating countries during 2015.

    – Final discussion of the article to be sent for publication in some scientific journal.

    – Analysis of outreach activities.
