Updated “recipes” for SOCAT quality control published in a new version of the cookbook

The Surface Ocean CO2 Atlas  (SOCAT) that was developed by the international marine carbon research community, celebrated its 10th anniversary in 2017. It provides a synthesis of quality-controlled, surface ocean fCO₂ (fugacity of carbon dioxide) observations, and is a milestone for biogeochemical and climate research and in informing policy. SOCAT data is readily available and can be used to quantify ocean carbon sink and ocean acidification, and to evaluate ocean biogeochemical models.

SOCAT data are released in versions, with each succeeding version containing new data sets and updates of the previous one. SOCAT version 1 was released in 2011. The most recent, version SOCAT version 6, comprises 23.4 million global oceans and coastal seas observations from 1957 to 2017, as well as calibrated sensor data.

A team led by Siv Lauvset (Bergen, Norway) recently released an updated “cookbook” of quality control procedures for SOCAT data. This update will be used from SOCAT version 7 onward. The revised quality control criteria will not be retrospectively applied to data sets in SOCAT versions 1-6. The “cookbook” is useful for quality control and to give those who wish to submit data to SOCAT an indication of what is required to achieve the highest quality rating. New data can be submitted at any time, and will be included in the next SOCAT release. The deadline for quality control of SOCAT version 7 is 31 March 2019.

Microbial Respiration, the Engine of Ocean Deoxygenation

Carol Robinson, University of East Anglia

This paper synthesis of current knowledge of microbial plankton respiration in relation to deoxygenation, including the drivers of its variability and possible constraints to our ability to project future scenarios.

Microbial plankton respiration is key to the balance between the storage of organic carbon in the oceans or its conversion to CO2 with accompanying consumption of dissolved oxygen. Many areas of the world´s oceans have experienced reduced dissolved oxygen concentrations for the past 50 years, and this ocean deoxygenation trend it seems set to continue. Despite its central role in ocean deoxygenation, microbial respiration is one of the least constrained microbial metabolic processes. There is thus the need for improved understanding of the magnitude and variability of respiration, and the attribution to component plankton groups. This, together with the quantification of the respiratory quotient, would enable better predictions, and projections of the intensity and extent of ocean deoxygenation and of the integrative impact of ocean deoxygenation, ocean acidification, warming, and changes in nutrient concentration and stoichiometry on marine carbon storage

The 8th China-Japan-Korea IMBeR Symposium and Training Course

The 8th IMBeR China-Japan-Korea (CJK) Symposium was held at the East China Normal University in Shanghai, China last month. The theme was Marine Biogeochemical Sciences for the Sustainability of the West Pacific Biosphere. In addition to participants from China, Japan and Korea, the symposium attracted researchers and students from Thailand, India, Pakistan, Sri Lanka, Malaysia and Canada.

Following the symposium, the IMBeR Human Dimensions Working Group held a training course. These meetings are held every second year and the next one will be in Thailand in 2020.

’Mind the Gap’ between ecosystem services classification and strategic decision making

Although ecosystem services are increasingly embedded in policy agendas, it is largely unknown if and how policy actors are considering them. This paper features a retrospective analysis of interviews with key policy actors involved in the strategic decision-making process leading to an innovative large-scale Dutch coastal management project, the Sand Motor mega beach nourishment. The interviews were analysed to ascertain which ecosystem services were considered and how they were described by policy actors. The findings suggest that broad, unspecified ecosystem services were adopted highly by the policy actors, while specific ecosystem service categories were rarely considered. Also, relatable and easy to understand cultural ecosystem services also constituted critical arguments for policy actors in their strategic decision making. The study suggests a ‘translation step’ between ecosystem services research and decision making for ecosystem services to truly align with relevant aspects of decision making.
