Interdisciplinary Marine Early Career Network (IMECaN) launched at the IMBeR Future Oceans2 conference

IMBeR officially launched its latest programme dedicated to students and early career researchers. The Interdisciplinary Marine Early Career Network (IMECaN) provides a networking platform, training programmes, and leadership opportunities for early career marine researchers. The official launch happened at a workshop at the Future Oceans2 Open Science Conference in Brest, France on 16 June 2019. The workshop focused on career development paths for marine researchers, and using infographics in research outputs.

IMECaN has lots of plans for the future, and will be providing training and development in areas not traditionally provided through formal curricula.

IMECaN currently has members in 59 countries and we hope to encourage more people to join up – so help us spread the news. More info about IMECaN and  sign up to receive updates on activities and events organised by IMECaN.

IMBeR at the 2019 SOLAS Open Science Conference in Sapporo, Japan

The Surface Ocean-Lower Atmosphere Study (SOLAS) held its 7th open science conference in Sapporo, Japan from 21-25 April 2019. Members of IMBeR Japan Committee, Jun Nishioka, Koji Suzuki and Masahiko Fujii from Hokkaido University, and Atsushi Tsuda from the University of Tokyo, attended the conference and presented an IMBeR poster highlighting the collaboration between IMBeR and SOLAS, including new research successes and trends.

SOLAS-IMBeR Interior Ocean Carbon working group, led by Niki Gruber, has determined the amount of man-made CO2 emissions taken up by the ocean from the atmosphere between 1994 and 2007.

The state of ocean CO2 uptake

The ocean is an important sink for anthropogenic CO2. From the beginning of the industrial revolution to the mid-1990s roughly 30% of our emissions have been absorbed by the oceans. This process is an important moderator of climate change, but can we count on it to remain as strong in the future? Gruber et al. calculated the ocean uptake of anthropogenic CO2 for the interval from 1994 to 2007, which continued as expected. They also observed clear regional deviations from this pattern, suggesting that there is no guarantee that uptake will remain as robust going forward

Marine heatwaves threaten global biodiversity and the provision of ecosystem services

Marine heatwaves (MHW) are periods of above average temperatures (above the expected 90th percentile) that persist for more than 5 days in a region. They provide an unwanted look at how the ocean might respond to temperatures that exceed the 2C target for limiting global warming. A study by an international team of researchers including IMBeR SSC member Alistair Hobday published a global review of the impact of MHW on species and habitats. damage marine heatwaves are causing to the marine environment wherever they occur. The research in Nature Climate Change demonstrates periods of extreme temperatures can cause rapid loss of marine habitat, local extinctions, reduced fisheries catches and altered ocean food webs. Regardless of where MHW had occurred, they had negative and often detrimental effects on all kinds of marine organisms, including plankton, seaweed, coral, fish, birds and mammals. Impacts on marine life were more severe at the warm part of the species range, as heatwaves elevate already relatively warm temperatures. Studies like this one contribute to addressing IMBeR Grand Challenge 1 – understanding and quantifying the state and variability of marine ecosystems.

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
