Observations and synthesis to establish variability and trends of oceanic pH
Lead Research Organisation:
University of East Anglia
Department Name: Environmental Sciences
Abstract
We propose a programme of observations, combined with analysis of past and ongoing time series, to discover the magnitude of surface pH variations at seasonal-up-to-decadal time scales. We will address the Atlantic, UK shelf and slope waters, and selected locations in the Southern Ocean, using data from time series stations and volunteer observing ships (VOS), measuring three parameters of the marine carbonate system. The programme will be integrated with the efforts of colleagues in other European countries, (enablng better and longer-term coverage, and of of a wider area). It will be co-ordinated with the Surface ocean carbon atlas project (SOCAT) which aims to produce the most comprehensive and up to date data base to access all the quality data relevant to ocean carbon uptake, and from which pH trends can be derived. Estimation of decadal trends change will be set against the background of intra- and inter-annual variation.

Description | Version 1 of the Surface Ocean CO2 Atlas (SOCAT) has been made public in September 2011. Version 2 of SOCAT has been made public in June 2013. Version 1 has been documented in 2 peer-reviewed publications (Pfeil et al., 2013; Sabine et al., 2013). Version 2 has been documented in 1 peer-reviewed publication (Bakker et al., 2014). Version 3 was made public in September 2015 and has been documented in a scientific publication (Bakker et al, 2016). |
Exploitation Route | SOCAT products are used for the quantification of the global ocean carbon sink. Publications documenting SOCAT are cited in at least 18 scientific publications (as of 24/04/2014). SOCAT products can be used in process studies, for quantification of the ocean carbon sink and its variation and for the initialisation and validation of ocean carbon models. The 2013 Global Carbon Budget has used SOCAT (Le Quere et al., 2013 - accepted for ESSD). |
