The observation-based pCO₂ fields were created using a 2-step neural network technique. In a first step, the global ocean is divided into 16 biogeochemical provinces using a self organizing map. In a second step, the non-linear relationship between variables known to drive the surface ocean carbon system and gridded observations from the SOCATv2 dataset (Bakker et al. 2014) is reconstructed using a feed-forward neural network within each province separately.

The organizers aim to expand the scope of the meeting to include measurements of dissolved greenhouse gases and related ocean tracers for the first time! First circular

Climatological mean monthly distributions of pH in the total H+ scale, total CO₂ concentration (TCO₂), and the degree of CaCO₃ saturation for the global surface ocean waters (excluding coastal areas) are calculated using a data set for pCO₂, alkalinity and nutrient concentrations in surface waters (depths less than 50 m), which is built upon the GLODAP, CARINA and LDEO database.

The Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM website) program will commence in September 2014 with an initial commitment of $3.5 million per year over 6 years ($21 million dollars total). SOCCOM program is a six‐year initiative funded by the US NSF to drive a transformative shift in the scientific and public understanding of the role of the Southern Ocean in climate change and biogeochemistry.

An interesting compilation of the state of ocean acidification research and understanding has just been published and can be downloaded here.

With the advent of new sensors and platforms to measure surface water CO₂ levels, the dataset quality control criteria are updated in SOCAT to accommodate surface water fugacity of CO₂ (fCO₂) data from these sensors.

This year’s OCB summer workshop will take place July 22-25, 2013 at the Woods Hole Oceanographic Institution in Woods Hole, Massachusetts. Please visit the workshop website at http://www.whoi.edu/workshops/ocbworkshop2013/  for more information and to register to attend. The registration deadline is June 19, 2013.

POGO is pleased to announce that it will once again offer a special POGO Visiting Fellowship for training on-board an Atlantic Meridional Transect (AMT) cruise in 2013.  

The purpose of this message is to invite you to propose members for the new Ocean Acidification international Reference User Group (OA iRUG). Please forward this message as appropriate to your contacts.
