The International Group for Marine Ecological Time Series (IGMETS) has released its report entitled “What are Marine Ecological Time Series telling us about the ocean? A status report” (http://igmets.net/2017 or 
This report presents an analysis and overview of oceanic trends through the end of 2012, based on a collection of over 340 in situ marine ecological time series, and supplemented with satellite-based spatio-temporal sea surface temperature and chlorophyll background fields. This report features electronic supplements in the form of a Metabase (http://igmets.net/metabase) and the IGMETS time series Explorer (http://igmets.net/explorer), which allow users to further expand on the information featured in the text. The information contained in the report and IGMETS metabase is relevant for a number of Essential Ocean Variables (EOVs), including the biogeochemistry ones.
