Applying an Organizational Psychology Model for Developing Shared Goals in Interdisciplinary Research Teams

Developing shared goals within interdisciplinary marine research teams can enhance success, both in terms of knowledge production processes, and efforts to link that knowledge to decision-making processes. However, there is very little guidance available for how best to develop shared goals that reflect the values and perspectives of all team members. In a new Perspective Paper just published in One Earth, Chris Cvitanovic and colleagues explore the utility of an organisational psychology model – the ASPIRe model – for developing shared goals within interdisciplinary marine research teams. They do so by applying the model to the Centre for Marine Socioecology in Tasmania, Australia – a group that brings together marine experts from a number of organisations and with varied disciplinary expertise including physics, law, economics, biology, sociology and governance. The full paper is Open Access and can be found here

The IMBeR ClimEco7 Summer School is now open for applications

We are very pleased to announce that we are now accepting applications for the 7th IMBeR 'Climate and Ecosystems' Summer School that will be held at UBC in Vancouver, Canada from 17-21 August 2020.

Numbers are limited to between 60-70 ClimEco7 participants to ensure good discussions and interactions between participants and the amazing lecturers. So when you apply, tell us why you should be selected to attend. We look forward to receiving applications from a wide range of ocean science disciplines.

The registration fee is still to be confirmed. No payment is necessary at this stage. Successful applicants will be informed of the deadline for payments later.

A new IMBeR International Project Office at the East China Normal University (ECNU) in Shanghai, China

Last week, Carol Robinson, the Chair of the IMBeR Scientific Steering Committee, joined the IMBeR project office staff - John Claydon and Lisa Maddison from the International Project Office in Norway, and Fang Zuo and Kai Qin from the Regional Project Office in China - at a ceremony to mark the inauguration of the new International Project Office (IPO) in Shanghai, China.

A Memorandum of Understanding to support the IMBeR IPO-China for the next five years was signed by Carol Robinson and the ECNU President Prof. Qian Xuhong. The office is also supported by a consortium of supporting marine institutions and projects.

Tuna carbon isotopes suggest global shift in phytoplankton communities

Research by the CLIOTOP Marine Predator Isotopes Task Team was recently published in Global Change Biology. The study compiled more than 5000 stable isotope values from 2000 to 2015 of three tuna species sampled globally. Their analyses, unprecedented in scope and spatial range, found a decline in tuna δ13C values of up to 2.5‰ which was up to five-fold larger than expected from the Suess effect alone, i.e. fossil fuel-derived and isotopically-light carbon incorporated into marine food webs. The team used time-series analysis and Bayesian modelling to relate the observed temporal trend to various processes known to influence ocean carbon cycling in the global oceans. The study concluded that tuna isotope signatures are not only indicating changes in fossil-fuel derived carbon emissions but also a substantial shift in phytoplankton communities (from a likely dominance of larger diatoms to smaller coccolithophorids, flagellates or cyanobacteria).

More than 90% of the heat associated with global warming, and more than 30% of the fossil-fuel carbon emissions have been absorbed by the oceans. While such processes are predicted to impact marine biota through changes in ocean stratification and ocean acidification, current estimates of trends are based on localized ocean time series or satellite observations with significant uncertainties.

The findings from this CLIOTOP study could have broad ramifications for marine food webs. Such shifts in phytoplankton could decrease the availability of energy and some essential macro and micro nutrients to fish and human consumers. The study represents a heretofore unrecognized application of stable isotope analyses to reveal decadal changes in the ocean carbon cycle. Such empirical data will be invaluable in calibrating and validating global earth system models used by the IPCC to project the effects of climate change on oceanic productivity.

Global carbon budget 2019

The 2019 “global carbon budget” was published on 4 December. It provides an assessment of anthropogenic CO2 emissions and their distribution in the atmosphere, ocean, and land. This is important to better understand the global carbon cycle, support the development of climate policies, and project future climate change. It shows that emissions are still increasing, but have slowed due to the global decrease in coal burning. Continued and increased global action is needed to reverse the trends.

ESSAS 2020 Annual Science Meeting in Japan from 1-3 June

IMBeR´s ESSAS Regional Programme will hold its 2020 Annual Science Meeting at Hokkaido University in Sapporo, Japan from 1–3 June 2020

ESSAS´s goal is to compare, quantify and predict the impact of climate variability on the productivity and sustainability of Subarctic and Arctic marine ecosystems. The theme of the 2020 meeting is Linking past and present marine ecosystems to inform future fisheries and aquaculture. This builds on a Belmont Forum-funded project that examined the resilience and adaptive capacity of Arctic and Subarctic marine systems, and aims to gain greater understanding of the mechanisms by which climate change will affect aquaculture and capture fisheries, how these changes will affect resource-dependent communities, and how management can foster resilience in these systems.

Registration and abstract submission are now open. We invite you to submit abstracts that address these themes to help inform our understanding of future changes affecting fisheries and aquaculture in high-latitude marine ecosystems. We welcome contributions from different marine science fields, including paleoecology, contemporary ecology and the social sciences. In an effort to reduce our carbon footprint, presentations can be delivered via a video conference system if you cannot atttend the meeting.

If you would like to join the optional excursion to the UPOPOY National Ainu Museum and Park on 5 June, please sign up for it when you register.

Deadline for abstract submission: 31 January, 2020

Deadline for online registration: 30 April 2020

Registration fee: Students: 2,500 JPY, Others: 5,000 JPY

The smallest phytoplankton may be bigger than we first thought

The ability of flow cytometry to sort hundreds of thousands of phytoplankton cells in minutes has been used in marine science for over 30 years. However, the differentiation of these cells into different types and then further into size distributions and optical properties still requires the manual interpretation of skilled analysts.

We have developed and implemented an automated scheme on the large Atlantic Meridional Transect flow cytometric database consisting of around 104 samples and 109 cells. This unique, well-calibrated dataset covers 100° of latitude between the UK and the Falklands, and has multiple samples between the surface and 200m. The results clearly show that Prochlorococcus, which are very small marine cyanobacteria, are consistently larger (>0.65 µm) than previously thought and have a distinctive double peak (0.75 µm and 1.75 µm) in their size distribution, which varies strongly with depth. This is coupled with changes in their optical properties: a term we have coined as “opto-types”. Synechococcus by contrast are strongly monodispersed and are typically 1.5 µm in diameter.

This work has uncovered new information regarding the size distribution of the smallest phytoplankton and has implications for how energy is transferred between different biological organisms.
